When it comes to heating and cooling comfort in your home, you want the best. In 2025, it’s time to upgrade your HVAC system to ensure top-notch performance and lower energy costs.
Let’s dive into the 10 HVAC considerations our Martens Heating and Cooling technicians recommend for homeowners throughout the Fox Valley this year.
- Schedule Preventative HVAC Maintenance
Annual or bi-annual preventative maintenance is the key to having a well-functioning HVAC system. Expert HVAC technicians thoroughly inspect your air filters and ductwork, clean coils, check refrigerant levels, and much more to extend the life of your HVAC unit and prevent major repairs or safety risks.
Martens Heating and Cooling has been helping homeowners throughout Appleton, Oshkosh, and the Fox Cities to maintain efficient, fully functional HVAC systems that keep families comfortable year-round since 1970.
“They have a great yearly maintenance plan and are always efficient. They also go the extra step if they see something that can be improved with your setup.” — Nicole K.
- Replace Air Filters
Replacing your unit’s air filters is one of the simplest yet effective ways to keep your HVAC system running smoothly. Dirty or clogged HVAC filters can restrict airflow, forcing your system to work harder and consume more energy. This increases your utility costs and your system’s wear and tear.
We recommend replacing the air filters in your Fox Cities home every one to three months. This replacement depends on overall HVAC usage and your household, such as if you have pets or seasonal allergies.
Try to check your filters regularly and contact our team if you need help with replacement. Making this a priority in 2025 will leave your home feeling fresh!
- Plan for Seasonal Changes
As Wisconsinites, we know how quickly the weather can change, no matter the season. Adapting your HVAC system to these seasonal changes can keep your unit running at its peak performance.
Before the winter season, double-check that your furnace is clean and running efficiently. Before summer rolls around, you’ll want to inspect your air conditioning unit, ensuring it’s clean and ready to fight the Wisconsin heat and humidity.
Sealing gaps in windows, cleaning vents, and inspecting insulation can help maintain consistent temperatures in your home. By planning ahead, you’ll be able to enjoy a comfortable home year-round.
- Upgrade to Smart Technology
Smart technology continues to improve how homeowners across Northeast Wisconsin manage and use their HVAC systems.
Smart thermostats allow you to set custom schedules, adjust temperatures from your smartphone, and optimize energy usage based on your schedule and habits. Some advanced systems even automatically learn your preferences or detect when people are no longer in a room to limit energy usage and heat or cool rooms in your home as needed.
According to Energy Star, a certified smart thermostat can save you an average of 8% on your heating and cooling bills.
- Address Indoor Air Quality
Indoor air quality has become a larger focus for Wisconsin homeowners to create a comfortable and safe living environment.
Poor air quality can lead to respiratory problems, allergies, and discomfort caused by common home pollutants, including dust and pet dander. You can invest in air purifiers for your home, but advanced filtration from your home’s HVAC unit can make a true difference.
At Martens Heating and Cooling, we offer humidification, dehumidification, filter media cabinets, and UV lights that can clean your air of pollutants while optimizing the air you breathe. If improving air quality isn’t on your list of to-do’s for your home, it should be in 2025!
“Fair estimate at a fair price to have central air, whole house purifier, and humidifier installed. Everything was installed by Jeremiah, and it went extremely well and I am very happy with [the] service and products sold by Martens. All the folks were friendly and presented plenty of options for me to make an educated decision on the best route to take with my house.” — Chad C.
- Prepare for Extreme Weather Events
Extreme weather events have become increasingly common throughout the United States, and your HVAC unit must be ready to handle the changes. Whether Wisconsin is going through a heatwave, deep freeze, or severe storm, you need to be able to rely on your system to keep you and your family safe and comfortable.
Start by installing surge protectors to protect your HVAC system against power outages or electrical surges. Having a generator on hand is also beneficial to keep your home’s unit running during a power outage.
Make sure to also protect your outdoor HVAC unit by cleaning debris and securing it against high winds or potential flooding.
“Marten’s is the best! It was quite the week with our air conditioning system leaking in the ceiling and our boiler going out when temps reached zero! Alex fixed up the insulation around the piping of the A/C in the ceiling. Not an easy feat, and he did an amazing job. Jeremiah kept our old boiler limping along with multiple visits, and Marten’s scheduled our new install right away. Now we are dry and warm. Top-notch service, courteous, professional, and knowledgeable. I highly recommend them.” — Melissa
- Consider Ductwork Maintenance
Your home’s ductwork is responsible for delivering heating and cooling throughout your home. Over time, your ducts can accumulate debris, dust, and even mold. These issues can reduce your unit’s efficiency and negatively impact indoor air quality.
Leaking or poorly insulated ducts can cause your HVAC system to work harder, adding wear and tear to your unit while increasing monthly utility costs.
Inspect, clean, and seal your ductwork to ensure everything is working properly, and contact our Fox Cities HVAC professionals if you need assistance.
“You won’t regret going with these guys! Three guys came to my house to install a new air conditioner/furnace and some ductwork. Very friendly and informative and cleaned up after themselves. 5 stars.” — Alex S.
- Stay Informed About HVAC & Energy Innovations
Technology is ever-evolving, and the technology connected to HVAC systems is no different. New developments in geothermal heating and cooling systems, hybrid HVAC solutions, and smart zoning can improve energy efficiency and provide more control and customization.
Keeping up with trends can help you make informed decisions about upgrading your HVAC system and when you should incorporate the latest technology.

“I called Martens Heating today on Christmas Morning. Our furnace was not working. The owner, Jason, answered and stepped me through all the steps to check and try to fix it. The plan was for him to come over later in the afternoon if we didn’t get it started back up. He did get me through to get it to work, and I am extremely grateful for what he did.
