“Should I be doing anything to get my AC ready for spring?”

The short answer is yes. Scheduling an AC spring tune-up is one of the best ways to make sure your air conditioner is ready for warmer weather.

Your air conditioner has been sitting idle for several months, and just like any mechanical system, it works best when it’s inspected and maintained before you rely on it again. A professional AC spring tune-up can help prevent breakdowns during the first hot days of summer and keep your system running all season long efficiently.

Here are a few things we typically recommend homeowners keep an eye on.

It’s Been Over a Year Since Your Last AC Spring Tune-Up

If your system hasn’t had an AC spring tune-up in over a year, it’s a good idea to schedule maintenance before the cooling season begins.

During a typical spring tune-up, a technician will inspect the electrical components, check refrigerant levels, clean the outdoor unit, test the system’s performance, and make sure everything is operating safely and efficiently.

Catching small issues early can make a big difference when temperatures start climbing later in the season.

Rising Energy Bills Can Signal Your AC Needs Maintenance

If your energy bills seemed higher than usual last summer, your air conditioner may have been working harder than it should.

Dirty coils, clogged filters, or low refrigerant levels can all reduce efficiency. When your system has to run longer to cool the same space, that extra strain shows up on your energy bill.

Unusual Noises Could Mean Your AC Needs Attention

Air conditioners aren’t completely silent, but they shouldn’t be making loud or unusual sounds either.

If you notice banging, rattling, grinding, or buzzing when the system starts running, it could be a sign that something inside the unit has loosened or worn down. These issues often start small but can turn into larger repairs if they aren’t addressed early.

Having a technician check things out before summer arrives can help avoid a mid-season breakdown.

Uneven Cooling Throughout the Home

Another thing we hear from homeowners is that certain rooms in the house never seem to cool down as well as others.

Uneven cooling can sometimes point to airflow issues, dirty components, thermostat problems, or even ductwork leaks. We can help pinpoint the cause and make sure your system is distributing air properly throughout the home.

Warm Air Coming From Your Vents

If you turn your system on for the first time in spring and warm air starts blowing through the vents, that’s a clear sign something isn’t right. When the first hot day hits Wisconsin, the last thing anyone wants is an air conditioner that’s acting more like a heater. A quick AC spring tune-up can help identify the issue before summer temperatures arrive.

In some cases, it could be as simple as a thermostat setting, but it can also indicate refrigerant issues, compressor problems, or blocked airflow. Getting the system checked early helps ensure you’re not left without cooling when summer heat arrives.

Older Air Conditioners Need Regular Tune-Ups

Most air conditioning systems last somewhere between 10 and 15 years with proper maintenance.

If your system is approaching that age, routine tune-ups become even more important. Regular maintenance can help extend the life of your equipment and give you a better idea of when replacement might eventually make sense.

Why Spring Is the Best Time for an AC Tune-Up

From a technician’s perspective, spring really is the ideal time to schedule an AC tune-up.

By the time the first 85-degree day hits Wisconsin, HVAC companies across the Fox Cities are responding to emergency calls and system breakdowns. Getting your system checked early helps ensure everything is working properly before the summer rush begins.

Getting your AC spring tune-up scheduled early ensures your system is ready before the summer rush begins.

The post Is Your AC Ready for Spring? What Homeowners Should Check First appeared first on Martens Heating & Cooling.

For many homeowners in the Fox Cities area, this decision can feel overwhelming. You want to stay warm without unnecessary expense and make the smartest long-term choice for your home.

At Martens Heating & Cooling, we help homeowners across Appleton, Oshkosh, and the Fox Cities weigh their options every day. Let’s walk you through how to know when a repair is still worthwhile, and when replacing your furnace may actually save you money..

When Furnace Repair Makes Sense

Not every furnace issue means you need a full replacement. In many cases, a timely repair can safely extend the life of your system.

A furnace repair may be the right choice if:

• Your furnace is under 10 years old and has been well-maintained
• The issue is minor (faulty ignitor, thermostat issue, sensor replacement, etc.)
• Repair costs are reasonable compared to the system’s value
• Your home is heated throughout all rooms, and energy bills haven’t increased

If this sounds like your situation, a professional furnace repair can restore comfort quickly. At Martens Heating & Cooling, we offer 24/7 emergency HVAC service throughout Northeast Wisconsin when you need it most.

Signs It’s Time to Replace Your Furnace

As your furnace gets older, repairs tend to happen more often and become more expensive, while efficiency declines. There’s a point where continuing to fix an old system becomes more expensive than upgrading.

You may want to start considering furnace replacement if:

• Your furnace is 10+ years old
• You’re frequently calling for repairs
• Repair costs are approaching 30–50% of the cost of a new system
• Your home has uneven temperatures or struggles to stay warm
• Energy bills continue rising despite repairs

A common rule of thumb is that if a repair costs more than half the price of a new furnace, replacement is the smarter investment.

Why Furnace Replacement Can Save You Money in the Long Run

While replacing your furnace has a higher upfront cost, it often pays off faster than you’d think.

Benefits of replacing an aging furnace in your Fox Cities home include:

• Energy-efficient furnaces can lower monthly heating bills
• More consistent and reliable heating
• Quieter operation and better indoor air quality
• Peace of mind knowing your system is dependable

Modern high-efficiency furnaces are designed to perform better in colder winters, and many Wisconsin homeowners are surprised by how much warmer their homes are after upgrading.

Flexible Financing Makes Replacement More Manageable

Cost is the top reason many Wisconsin homeowners put off a furnace replacement, and that’s completely understandable.

To help make replacement more accessible, Martens Heating & Cooling offers flexible financing options, allowing you to spread the cost of a new furnace over time instead of paying everything upfront.

What Counts as an HVAC Emergency?

Sometimes homeowners are a bit hesitant to reach out because they’re not sure if something is really an “emergency” or they’re concerned about those fees. Here are a few situations where you shouldn’t wait to call for help because it could impact your health and safety:

Furnace Isn’t Working in Freezing Weather

If your furnace stops working during freezing temps, that’s an emergency. Besides comfort for you and your family, no heat can cause pipes to freeze and burst, leading to extensive damage and expensive repairs.

Strange Smells or Smoke

If you smell gas, burning plastic, or smoke coming from your vents or furnace, shut the system off immediately and call for emergency HVAC service. These can be signs of a gas leak or electrical issue that poses a safety risk for you and your family. 

System Won’t Turn Off

If your HVAC system keeps running no matter what you do, it could mean a short circuit or faulty control board. This can cause overheating, equipment damage, and a potential fire if ignored.

Water Leaks or Ice Buildup

Leaking water or ice around your unit can mean something’s seriously wrong, like a blocked drain, frozen coil, or refrigerant leak. Catching these issues early on can prevent damage to your home and system and minimize future repairs.

When It Isn’t an HVAC Emergency

While we get that any HVAC issue is frustrating and concerning, not everything is an emergency or danger to you and your family. Some HVAC issues can wait until regular business hours, including:

• Uneven heating or cooling in certain rooms
• Minor noise changes
• A clogged air filter
• Regular maintenance or tune-ups

These are generally signs that you might need a repair or replacement soon, but there’s no immediate risk. 

If you’re unsure whether something is an emergency HVAC issue, it’s always better to call and ask. A trusted technician can help determine whether you need immediate service or can safely wait. Ultimately, waiting until normal business hours when possible will likely save you money on after-hours and emergency fees. 

What to Do in an HVAC Emergency

If your HVAC system stops working or something doesn’t seem right, don’t panic. Shut down the system, check for immediate dangers, and call a trusted emergency HVAC technician right away.

Let’s break down exactly what to do while you wait for help to arrive.

• Turn off your system. Shut down your furnace, AC, or heat pump at the thermostat and the breaker. This helps prevent further damage or hazards until an HVAC technician can come take a look. 
• Check for obvious issues. Common culprits include tripped breakers, dirty filters, and blocked vents. Sometimes, a quick reset or filter change can solve your problem.
• Leave if you smell gas or burning. Grab your family and exit your home immediately. Call your utility company or 911 before calling us.
• Protect your home from freezing. If your furnace is out and its freezing temperatures, open cabinet doors to allow warm air to reach pipes and put towels around them. Use space heaters safely to prevent freezing and keep your family comfortable.
• Call a trusted emergency HVAC technician. Once you and your family are safe, contact Martens Heating & Cooling for emergency HVAC services. We’ll walk you through the next steps while dispatching a technician to your home.

So, what can you do?

Investing in a whole-home humidifier can help keep your family healthy, make your home more comfortable, and support HVAC efficiency all season long.

What Is a Whole-Home Humidifier?

A whole-home humidifier works with your home’s furnace or HVAC system to add moisture to the air as it circulates through your ducts. A whole-home humidification system, also called a central humidifier or furnace humidifier, maintains a consistent humidity level throughout your entire house.

There are a few common humidification options:

• Bypass humidifiers: These use the warm air from your furnace to evaporate water and circulate humidity through your ducts. These work well in small or medium-sized homes with ductwork
• Fan-powered humidifiers: This type includes a built-in fan to move air across the water panel, making them more effective for larger homes.
• Steam humidifiers: These humidifiers generate steam directly and are the most precise option for homes that need tight humidity control.

Whole-House Humidifiers vs. Portable Humidifiers

When it comes to humidification, it often comes down to a portable humidifier or a whole-home humidification system. 

While a whole-house or furnace humidifier is installed directly into your home’s HVAC system, a portable humidifier is a standalone unit. It releases moisture directly into the air in a single room. 

You have to fill the tank manually with water and plug it in. The humidifier will run until the tank is empty or the room reaches a certain humidity level.

Why Humidification Matters During Wisconsin Winters

Wisconsin’s cold, dry winters often bring indoor humidity levels below 25%. Ideally, you want your home between 30% and 50% humidity. Below that range, the dry air can impact your health and your home’s structure.

When the air gets too dry:

• Skin and sinuses become irritated: Low humidity pulls moisture from your body, leading to cracked lips, nosebleeds, and irritated throats that are both annoying and painful.
• Static electricity builds: This leads to shocks when touching random items in your home and impacts your hair and clothes. 
• Wood dries out: Flooring, doors, and furniture can shrink, crack, or warp as they lose moisture due to the dry air. 
• Allergens increase: Dry air irritates nasal passages and can make you more susceptible to colds or allergies.

The Benefits of a Whole-Home Humidifier

Installing a whole-home humidifier can improve your comfort and health during Wisconsin’s long, dry winters while protecting your home’s structure and finishes.

Healthier Air

Proper humidity helps your body’s natural defenses work better and reduces the spread of viruses. It also soothes dry skin and sinus irritation that are common in winter.

Protection for Your Home

Your hardwood floors, trim, musical instruments, and furniture will stay in better condition when the air isn’t actively drying them out.

Low Maintenance

Once installed, your whole-house humidifier runs automatically with your HVAC system. You’ll just need annual maintenance, which usually just means replacing the water panel or filter once a year.

How to Choose the Right Whole-Home Humidification System

The right humidifier depends on the size of your home, the type of furnace you have, and  what type of humidity control you’re looking for. Since each home is different, it’s best to work with an HVAC company to discuss your specific requirements. 

Our certified HVAC technicians at Martens Heating & Cooling can:

• Measure your home’s needs
• Recommend the best model and capacity
• Integrate it with your existing HVAC system
• Set up an automatic humidity control (humidistat)

Get Full Home Comfort This Winter

Living in Wisconsin, where the air gets painfully dry every winter, means that a central humidifier it’s an investment in comfort, health, and home protection. 

If you’re curious whether a whole-home humidification system makes sense for your family, the HVAC experts at Martens Heating & Cooling are here to help. Our HVAC technicians travel throughout the Fox Cities and Northeast Wisconsin, including:

That’s where an Energy Recovery Ventilator (ERV) comes in. Not many homeowners in the Fox Cities are familiar with ERVs, so let’s break down what these systems do and whether one might be a good fit for your home.

What Is an Energy Recovery Ventilator (ERV)?

An ERV is an HVAC device designed to bring fresh outdoor air into your home while reducing energy waste. Think of it as a system that pre-conditions the incoming air to let your house “breathe” so your furnace or air conditioner doesn’t have to work harder.

How an ERV Works

The process is fairly simple. Here’s how an ERV works:

• Exhaust air out: The ERV pushes stale indoor air back outside.
• Fresh air in: At the same time, it pulls in fresh outdoor air.
• Energy exchange: As the two air streams pass through the ERV’s core, heat and humidity are transferred. 

In the winter, the outgoing warm air pre-heats the cold air coming into your home. In summer, the cooler indoor air helps reduce the temperature and humidity in the air entering. The result is cleaner, fresher indoor air without a big spike in your heating or cooling bills.

Benefits of an ERV for Your Wisconsin Home

That all sounds great, but will you actually notice a difference in your home? YES! You’ll notice your home feels fresher and less “stuffy,” no matter the season. From improved health to increased comfort and energy efficiency, energy recovery ventilators offer numerous benefits. 

• Healthier indoor air: Getting some fresh air into your Fox Cities home helps reduce indoor pollutants, allergens, and odors throughout the year. 
• Better humidity control: Humidity control is especially useful in Wisconsin’s muggy summers and dry winters. Your home will feel comfortable no matter what Mother Nature is doing. 
• Energy efficiency: ERVs can help keep heating and cooling costs lower compared to constantly opening windows or relying on less efficient ventilation systems. 

ERVs Make Sense in Wisconsin

Like it or not, living in Wisconsin means long, cold winters that dry out the air and humid summers that make it tough to stay comfortable. An ERV helps with both of those challenges:

In the winter, you’ll keep warm air inside while still getting some fresh air, helping reduce dryness and stale air without freezing. 

And ERVs provide much-needed relief in the summer, too. They reduce the amount of sticky humidity that enters your home, keeping your home cool and dry even on the hottest days.

Because the ERV recycles energy during the air exchange, your HVAC system doesn’t have to work as hard. That means lower energy bills all year long! Sounds great, right? 

Is an ERV Right for Your Home?

If you already struggle with dry winter air or damp, sticky summer air, adding an ERV to your HVAC system could be a game changer. ERVs are a great option for:

• New, tightly sealed homes that don’t “breathe” naturally.
• Families and pet owners concerned about allergies, odors, or overall air quality. 
• Any homeowner looking to improve comfort while keeping their energy bills under control.
• Anyone who wants fresher air year-round without constantly opening their windows.

Bringing Fresh Air Back Into Wisconsin Homes

Your home should feel comfortable and healthy in every season. With an Energy Recovery Ventilator, you can enjoy fresh air without wasting energy or stressing your HVAC system.

If you’re curious whether an ERV makes sense for your home, the HVAC experts at Martens Heating & Cooling are here to help. We’ll assess your home, walk you through your options, and recommend the best solution for your family’s comfort and budget — from mini-splits to ERVs.

The good news is you don’t have to sacrifice comfort to keep your energy bills in check. With a few smart strategies, you can stay cool and save money this summer. 

1. Close Your Curtains or Blinds

Be sure to close your curtains or blinds during the hottest part of the day to block out sunlight. This helps to reduce the heat that gets trapped in your house. Blackout curtains or thermal shades are another option to help you cut heat gain dramatically.

2. Use Fans

Ceiling fans and portable fans can help circulate air, which can help your home feel cooler. Fans don’t actually cool the air, but they make your body feel cooler by increasing evaporation on your skin and help push the cool air throughout your home.

3. Open Windows Strategically

One of the best things about Wisconsin weather is that the mornings and evenings are relatively mild. On cooler evenings and mornings, open your windows to let in the fresh Wisconsin breeze and reduce the need for AC. Just remember to close them before the temps start to rise for the day. 

4. Adjust Temperatures When You’re Not Home

When you’re away from home — whether you’re headed to the office for the day or going up north for the weekend — consider setting your thermostat to a higher temp to give your AC unit a little reprieve. If you’re gone during the day, the AC doesn’t need to run full blast. Setting it to 78–80°F is generally a good range and can save you a ton on your monthly cooling costs.

5. Use a Smart Thermostat

A smart thermostat learns your schedule and makes adjustments automatically, so you’re not cooling an empty house. Some smart thermostats even adjust based on the weather forecast, making the most of cooler days. As a bonus, some utility companies in Wisconsin will offer rebates on smart thermostats, making them affordable and saving you even more money. 

6. Change Your Air Filter

We recommend you change your air filter every 1–3 months—especially during peak summer. When filters are dirty, airflow is restricted, and your cooling system has to work harder to push air through. As a result, you’re using more energy and reducing cooling power. A clean filter gives you stronger airflow and the additional cooling power you need to be comfortable.

7. Schedule an Annual Inspection

Coils, refrigerants, and motors all need a little TLC sometimes. When coils are dirty, they can’t absorb or release heat efficiently, so your AC takes longer (and uses more electricity) to cool the same space. That’s why annual inspections are so important. If you’re looking for an HVAC inspection for your Fox Cities home, we can help. 

8. Seal Leaks & Drafty Areas

If cool air is leaking into your attic or crawlspace, your AC must run longer to cool your living areas. Minor home improvements, like sealing up leaks and insulating ducts, ensures the cold air gets where you want it.

9. Upgrade Your AC Unit

Don’t miss the signs that it’s time to upgrade your air conditioner. If your air conditioner is 10–15 years old, it may be costing you more than it should. Today’s models are significantly more energy-efficient. Look for Energy Star®-rated units, which can save you hundreds of dollars over their lifespan. 

10. Stay Cool With Martens Heating & Cooling

Staying cool in a Wisconsin summer doesn’t have to mean sky-high energy bills. If you’re dealing with AC issues, Martens Heating & Cooling is here to help. We offer AC maintenance, repair, and replacement across Northeast Wisconsin, including:

The post 10 Ways to Save Money on Air Conditioning This Summer in Wisconsin appeared first on Martens Heating & Cooling.

While we all want to stay cool and comfortable this summer, an overworked or inefficient air conditioning unit can result in higher energy bills and more wear and tear on your HVAC system than necessary.

Let’s explore a few of the common signs of HVAC inefficiencies and how Martens Heating & Cooling can help you stay comfortable and save money.

Spot the Signs of an Inefficient HVAC System

Many of our customers here in the Fox Cities don’t realize there’s an issue until their AC unit breaks down or they get a bill that’s way higher than expected.

”Small problems and minor inconveniences can turn into big emergency repair costs and potentially long down times during peak season. If something with your HVAC system doesn’t feel right, it’s important to be proactive,” said Jason Martens, owner of Martens Heating & Cooling.

These signs can help you detect an inefficient AC unit or other issues early:

Uneven Cooling

Some rooms are icy, others warm? Your home should have an even, comfortable cool. Uneven cooling is often a sign of airflow issues or leaky ductwork in your home. 

Longer Cooling Cycles

Does your AC run for a long period of time without really cooling things down? An AC unit that constantly runs and has long cooling cycles can indicate poor insulation, dirty filters, or even an undersized unit for the size of your home. 

Loud Or Whistling Vents

A lot of noise is usually a key indicator that something might be wrong. Whistling sounds, in particular, can indicate that your ductwork is too small or restrictive, which is putting strain on your system.

Dusty Home Despite Regular Cleaning

If you’re experiencing more dust around your home than usual or a musty smell, it may be due to poor filtration or leaky ducts. This can often be hard to notice because many families attribute the mess to pets, kids, or tracking dust in from outside during the summer months. 

Older Unit

If your HVAC system is more than 10 years old, it might be time for an upgrade. Even if things are technically still working and keeping your home cool, newer AC units are naturally more efficient. You want to make sure you’re taking advantage of potential savings! 

Summer Energy-Saving Tips for Wisconsin Homeowners

Before you crank the thermostat even lower, try these efficiency hacks to help beat the heat and reduce strain on your home’s HVAC system. 

Use a Programmable Or Smart Thermostat

Whenever possible, set schedules so your AC isn’t cooling an empty home. Smart thermostats are especially beneficial in the summer months, as schedules tend to be less predictable, and many Wisconsinites leave for extended periods to head up north or go on summer vacation. 

Replace or Clean Air Filters Monthly

This simple habit can have a big impact on overall AC efficiency. Clean filters maintain strong airflow and reduce energy waste throughout the summer and all year round. If you’re a pet owner or have allergies, replacing your filter is even more important. 

Close Blinds During Peak Heat Hours

We love the sunshine, but direct sunlight can quickly raise the temperature in your home. Closing blinds or using UV-blocking shades can keep you and your family cooler without having to rely on or adjust the AC.

Seal leaks and insulate

Gaps around your doors, windows, and ducts let cold air escape and hot air enter. Properly sealing and insulating your Fox Cities home keeps the cool air where it belongs—inside your home!

HVAC Upgrades that Pay Off

If you started with a self-check but your system still seems to be struggling, it might be time for a deeper look. That’s where Martens Heating & Cooling comes in. 

As a leading HVAC company serving Appleton, Oshkosh, Neenah, and the surrounding Fox Cities area, our contractors can help you find the right AC efficiency upgrades for your Wisconsin home. 

We offer: 

Ductwork Modifications

Many homes—especially older ones here in the Fox Cities area—have inefficient or poorly designed ductwork. Our team can evaluate airflow and recommend updates that reduce energy loss, improve temperature balance, and reduce your utility bills. 

System Assessments

Not sure if your current AC is the right size for your home? Hearing a funny noise? We’ll run a full system evaluation, measuring performance, age, and efficiency to guide your next steps, whether that’s a repair or replacement. 

Energy-Efficient HVAC Upgrades

Upgrading a 10-15 year old HVAC system to a high-efficiency system can lead to significant cost savings, primarily through reduced energy consumption. New, energy-efficient systems can lower heating and cooling bills by up to 20%. We’ll help you find the right system for your home, including mini-splits and ductless air conditioning solutions.

Stay Cool All Summer Long

Don’t wait until your system fails during a major Wisconsin heatwave. Suppose you notice any of these signs of inefficient air conditioners. In that case, Martens Heating & Cooling offers seasonal air conditioner repair, maintenance, and replacement in the Fox Cities to help you identify issues before they become costly problems.

After months of hibernation and severe temperature fluctuations, your AC unit needs some TLC to keep your home cool, comfortable, and energy-efficient this summer. A proactive approach to air conditioner maintenance and repair here in Wisconsin can save you time, money, and a whole lot of sweat when summer hits its peak.

Spring Is the Perfect Time for Air Conditioner Maintenance in Wisconsin

While things are starting to warm up, spring temperatures in Wisconsin are still relatively mild. Take advantage of it while you can! You want to make sure your air conditioning system is ready to go before the real heat and humidity set in. 

Avoid The Summer Rush & Wait Times

Wisconsin HVAC companies, including our team here at Martens Heating & Cooling, get swamped with emergency calls when that first big heatwave arrives. Scheduling spring maintenance ensures your unit gets attention before you actually have an AC unit breakdown and have to sweat it out while you wait. 

Catch Small Issues Early

Minor wear and tear from previous use or critters nesting inside your unit during the winter months can turn into expensive problems if ignored. Deal with it early on to minimize any further damage to your HVAC system and extend the life of your unit. 

Boost Energy Efficiency

With rising prices, we’re all more money-conscious than ever. The good news is that air conditioner maintenance can actually help you save money throughout the summer months. A clean, tuned-up AC runs more efficiently, which can reduce your utility bills. 

DIY Air Conditioner Maintenance Tips for Wisconsin Homeowners

Before we head into the peak of summer, here are a few things our Wisconsin HVAC experts recommend you do to help maintain your air conditioner. 

• Change the air filter every 1–3 months. If you have pets or allergy issues, it’s best to change more regularly. 
• Clear debris like leaves, twigs, and dirt from around your outdoor unit to minimize accidental damage. 
• Check your thermostat settings to ensure they’re ready for summer operation. If you have a smart thermostat, you can adjust temperatures to better align with your schedule. 
• Inspect ductwork in your Fox Cities home for loose connections or signs of mold, dust, and other buildup that can cause health concerns.
• Inspect the AC unit for signs of wear and tear or other issues. Be sure to also look at insulation, refrigerant lines, and more.
• Monitor your air conditioner for unusual noises, frequent cycling, warm air, or weak airflow. These are signs it’s time for an air conditioner repair or replacement for your Wisconsin home. 

Get Professional AC Maintenance for Peace of Mind

Don’t settle for a quick filter swap and call it a day. A thorough air conditioner inspection and maintenance visit from one of our qualified Wisconsin HVAC technicians can give you added peace of mind all summer long. Our air conditioner maintenance visits include:

• Inspecting and tightening electrical connections
• Cleaning the condenser and evaporator coils
• Checking and refilling refrigerant levels (if necessary)
• Calibrating the thermostat
• Lubricating moving parts
• Inspecting the ductwork for leaks or blockages
• Replacing or cleaning the air filter
• And more!

Since we know what we’re looking for, we can spot potential issues and offer solutions before you have a major issue on your hands. Will make sure your air conditioner unit operates efficiently and doesn’t have to work harder than necessary.

Is It Time to Replace or Upgrade Your Air Conditioner?

While maintenance is great, sometimes an air conditioner replacement or upgrade can be just the ticket to a cool, relaxing summer. Upgrading your system before peak temperatures can save you from mid-season breakdowns and unexpected expenses. Common signs it’s time for a AC replacement include: 

• Rising energy bills: Old and outdated AC units are less efficient than today’s ENERGY STAR®-rated models, so you’ll likely continue to see your bill going up. 
• Uneven cooling or hot spots: If your system may be undersized or struggling, you’ll likely feel inconsistent temperatures throughout your house. If that’s the case, upgrading to a bigger or newer unit could be the best option. 
• Frequent or costly repairs: If you’re constantly having to call our HVAC specialists, it’s likely that investing in a new unit may actually be more cost-effective long term.

• Smart Thermostat Compatibility: Many modern ACs work seamlessly with smart thermostats. While not 100% necessary, it’s a nice perk and can save you a lot of money due to efficiency. 
• Noise Levels: If you have a noisy air condition, give your ears a bit of a break. Newer units tend to be much quieter—perfect for Wisconsin homes where open windows and porches are cherished in summer.

If it’s time for an AC upgrade, our HVAC specialists are here to help you find the right size and efficiency to meet your cooling needs and offer seamless installation in your Fox Cities home.

If you want to enjoy the warmer weather without suffering from poor indoor air, UV light air purifiers and electronic air cleaners are game-changers. These powerful systems work with your HVAC system to keep your home’s air cleaner, healthier, and easier to breathe—especially during peak allergy season.

What Is a UV Light Air Purifier?

A UV (ultraviolet) light air purifier uses UV-C light to quickly kill or neutralize microscopic particles that could be floating through the air and your HVAC system. As the air passes over the UV light, it destroys airborne viruses, bacteria, and mold spores, so fewer of those irritants are recirculated into your home.

Benefits of UV Light Purifiers For Wisconsin Homeowners

• It kills mold, bacteria, and viruses, and it is great for preventing those annoying spring colds.
• Reduces unpleasant odors from mildew, pets, or cooking.
• Lowers allergy triggers like mold spores that thrive in damp basements or ductwork.

What Is an Electronic Air Cleaner?

An electronic air cleaner uses an electric charge to trap and remove dust, pollen, smoke, and pet dander from your air. The air passes through a filter that catches larger particles and moves through an electrically charged section that zaps smaller particles, causing them to stick to collector plates inside the unit. You can easily clean these plates to keep the system working at its best.

Benefits of Electronic Air Cleaners for Wisconsin Homeowners

• Captures up to 99% of airborne particles, including allergens like pollen.
• Helps reduce asthma and allergy symptoms.
• Improves airflow in your HVAC system, which can help with energy efficiency.

Why Improve Your Indoor Air Quality in Wisconsin This Spring

Wisconsin springs are unpredictable. With the dramatic temperature shifts and precipitation, we tend to keep windows closed, which impacts ventilation. That’s when UV air purifiers and electronic air cleaners become especially helpful in fighting dust, germs, pollen, and other allergens. 

Combat Seasonal Allergies

Pollen, mold, and dust are often at their highest in the spring, which is no fun for allergy sufferers. Electronic air cleaners and UV purification systems can reduce irritants, providing some much needed relief in your home. 

Fight Springtime Germs

After spending the long Wisconsin winter trapped inside, viruses and bacteria can linger in ductwork. UV lights can help eliminate them, creating a healthier space for you and your loved ones. (They’re especially helpful if you have children who tend to bring home all those school germs all year long!)  

Boost Indoor Comfort

Even if you don’t have allergies or other concerns, you’ll likely notice an immediate difference with your electronic air cleaner or UV purification system. The clean air feels fresher and helps your whole home feel more comfortable, especially on damp, rainy days.

Ready to Breathe Easier This Spring?

Let’s make this your healthiest spring yet. Adding a UV light air purifier or electronic air cleaner to your HVAC system is a smart, long-term solution for cleaner air all year round.

Serving the Appleton, Oshkosh, and the Fox Cities area, Martens Heating & Cooling has been helping Wisconsin homeowners stay comfortable for 50+ years. Our Wisconsin HVAC experts can recommend the best air purification system for your Fox Cities home and handle the installation with care.

What if there was a way to keep your home perfectly comfortable year-round without adding expensive ductwork or going bankrupt from your energy bills? That’s where mini split systems come in. These ductless heating and cooling units are gaining popularity among Wisconsin homeowners—but are they the right fit for your home? 

Today we’re answering some of the most common questions we get about mini splits from our customers around the Fox Cities to help you decide if they’re worth the investment for your home.

What is a Mini-Split System?

A mini-split system is a ductless heating and cooling system that allows you to control the temperature in specific rooms or zones. These systems use an outdoor compressor unit and one or more indoor air handlers, offering flexibility and energy efficiency without extensive ductwork.

Why Choose A Mini-Split System?

Great question! Many Wisconsin homeowners choose a mini-split air conditioning system for improved energy efficiency, more control over their home’s heating and cooling, and lower costs. Some of the key benefits include: 

• Save Money on Your Heating & Cooling Bills: Mini-splits let you zone your comfort, saving you money. You only pay to heat or cool rooms you’re using! 
• No Ductwork Needed: Ductwork can be expensive. Mini-splits don’t need it, which makes it a convenient and affordable option for older homes, garages, and workshop areas here in Wisconsin. 
• Peace and Quiet: Mini-splits are much quieter than traditional air conditioners and noisy window units so that you can relax without constant noise.
• Year-Round Comfort: Most mini-splits have both heating and cooling options, which is a must with Wisconsin’s crazy temperatures and weather fluctuations. 
• Control Your Comfort, Room by Room: No more bickering over temperatures. Mini-splits allow for individual room temperature settings so everyone is happy and comfortable. 

Are Mini-Splits Efficient​?

Yes! Mini-splits are among the most energy-efficient heating and cooling options available. And they use technology to allow you to adjust output based on demand. For people without a ducted system mini-splits are more efficient than window air conditioners. Energy savings, comfort, and noise reduction — it’s a win-win.

Do Mini Splits Work in Older Homes? 

Yes, mini-splits are a great option for older homes here in the Fox Cities area! Since these systems don’t require ductwork, they’re ideal for homes built before central HVAC systems were common. If you’re planning to remodel or update your home, they also work for additions, garages, basements, and other spaces that didn’t originally have heating and cooling.

How Long Do Mini Splits Last? 

A high-quality mini split system can last 15-20 years with proper maintenance. Regularly cleaning your filters and annual inspections will keep your system running efficiently for years, making these a great long-term investment for your home. 

How Big of a Mini Split Do I Need​?

The size of the mini split system you need depends on the square footage of the space. The quality of your insulation and layout can also impact sizing. 

Our team of experienced HVAC experts can help you find the right size mini-split, but here are some general guidelines to get you started: 

• A 9,000 BTU mini-split unit can cover about 350 square feet
• A 12,000 BTU mini-split unit can cover up to 500 square feet
• A 18,000 BTU mini-split unit can cover up to 750 square feet
• A 24,000 BTU mini-split unit can cover up to 1,000 square feet

(BTU stands for British Thermal Units, which is used to measure heat.) 

We recommend you get a professional assessment to ensure your mini-split system is properly sized for both heating and cooling. Oversized or undersized units can result in wasted money and uncomfortable nights when Wisconsin temps hit extreme highs and lows. 

Are There Any Incentives for Installing a Mini-Split in Wisconsin? 

Yes! Many Wisconsin utility companies offer rebates for installing energy-efficient heat pumps — including mini splits. You may also qualify for federal tax credits. Our team of experienced Wisconsin HVAC contractors and your local energy provider can help you find out the specific incentives for your home. 

In general, Wisconsin homeowners will spend $2,000-$5,000 for a single-zone mini split (one indoor unit) and between $5,000-$15,000+ for a multi-zone system (multiple indoor units). 

The cost of your mini-split system fluctuates based on the size, number of units needed, and installation factors such as electrical upgrades. 

Keep in mind that while that upfront investment may seem big, these mini-split systems offer long-term savings due to their high efficiency. And rebates and tax incentives can help balance out some of the initial costs.
