5 Signs It’s Time to Replace Your Air Conditioning Unit

Temperatures are rising across Wisconsin, and the humidity is already noticeable when you step outside. Before we hit the peak summer months throughout the Fox Valley, ensure your air conditioning is running correctly when you need it most. 

Here are a few indicators that it’s time for an air conditioning replacement before the summer heat sets in. 

1. Age of the AC Unit

As air conditioning units age, they lose efficiency and are more prone to breakdowns, leading to increased repair costs and energy consumption. An aging unit often struggles to effectively provide cold air to your home, resulting in uneven temperatures and discomfort. 

If you’ve noticed a steady increase in your energy bills without an increase in usage, it might indicate that you have a broken air conditioning unit or an older system. Most AC units are designed to last between 15 to 20 years, depending on the level of maintenance and usage. 

As AC units age, they lose efficiency, requiring more energy to maintain the desired temperature in your home. This inefficiency increases utility costs and puts additional strain on your system, potentially accelerating its wear and tear. 

According to Wisconsin Public Service (WPS), once your air conditioning unit is over 12 years old, you can end up paying up to $1,000 per year in cooling costs. 

Some customers note that their energy bills skyrocketed during the summer months, even though they scheduled regular maintenance. After replacing their outdated unit with a newer, energy-efficient model, they saw a significant reduction in their monthly energy costs and enjoyed a more consistent and comfortable indoor climate. 

If your air conditioner is approaching or exceeding this age range, consider a replacement to ensure reliable and efficient cooling for your Northeast Wisconsin home.

2. Frequent Repairs

If you frequently have to call us or another HVAC business in the Oshkosh or Appleton area for air conditioning repairs, it might be a sign that your unit is on its last leg. Constant breakdowns disrupt your comfort and lead to mounting repair and utility bills that can quickly add up. 

At a certain point, the cost of repeated repairs can approach or even exceed the cost of a new unit. Frequent repairs often indicate underlying issues that can’t be permanently fixed with replacement parts. Plus, an aging system will continue to deteriorate over time. 

Don’t endure a summer of repeated repair services and escalating costs before replacing your old unit. Investing in a new air conditioner ensures you enjoy consistent cool air and peace of mind free from the hassle of constant repairs.

“We had a new furnace and AC installed. Martens was very responsive and had great communication. Martens was one of several quotes that we had and Martens did the most thorough job beforehand by far. We felt confident choosing them. Our installers did a great job. Alex was very knowledgeable and friendly. He made sure we understood the new units and thermostat. He also did a very thorough job cleaning up after! I’d highly recommend Martens to anyone!” — Maci W.

3. Inefficient Cooling

If you notice that your air conditioner is running constantly but struggling to maintain a comfortable temperature, it’s likely that the system is no longer operating efficiently. 

This inefficiency can result in certain areas of your home feeling warm while others are overly cool, causing discomfort and frustration for you and your whole family. An inefficient unit also consumes more energy to reach the desired temperature, leading to higher utility costs. 

If your old air conditioner can’t keep up during the hottest Wisconsin days, despite adjusting the thermostat, it’s likely time to replace your unit. 

4. Strange Noises or Odors

Unusual sounds or odors are a pretty obvious sign that something is wrong with your air conditioner. These issues can signal serious problems and may even pose a health risk, so it’s not something you should ignore. 

Noises such as grinding, squealing, or banging can signal mechanical issues with your AC or worn-out components within the system. These noises often indicate problems that could lead to more severe damage and expenses if not addressed immediately. 

Strange odors coming from your AC unit, such as musty or burning smells, can indicate mold growth, electrical issues, or other serious problems. Ignoring these signs can compromise indoor air quality and pose health and safety risks such as fires, breathing issues, and depleted oxygen levels. 

5. Air Conditioning Failure

Experiencing a complete failure of your air conditioning system is a clear indicator that replacement is necessary

When your AC stops working altogether, especially during peak Wisconsin summer months, it can lead to significant discomfort and inconvenience for your household. This could be caused by many factors, such as compressor failure, refrigerant leaks, or electrical issues that are beyond repair. 

By upgrading to a new, reliable unit, you can regain peace of mind and uninterrupted comfort in your home. 

“[The Marten’s team] came on time, were pleasant to talk with during the installation, answered all my questions during installation, and explained things in a manner that I understood. After they left, I felt like I had chosen the best business of the nine that quoted the job. I would happily recommend this business to all. Thanks for an excellent job guys.” — Terry G.
