Walking into your air-conditioned home after a day in the hot sun will always put a smile on your face. But what happens if you have an A/C blowing warm air instead of cold? The experts at New Berlin Heating & Air Conditioning have the answer. Below, we’re sharing reasons why your system isn’t working like it should—and what you can do about it. Read it over, then call us at 262-784-8889.
Causes of a Central A/C Not Blowing Cold Air
Wrong Thermostat Setting
Believe it or not, sometimes the wrong thermostat setting can cause a lot of comfort problems. Make sure your device is set to “cool” and the fan is set to “auto.” That way, you can be sure your air conditioner is at least running according to your preferred settings.
Having a Wi-Fi thermostat can also help solve this problem, as you can schedule temperature changes according to your daily routine. It also lets you control adjustments straight from your smartphone.
Dirty Air Filter
Another simple reason why your A/C is blowing warm air—your air filter is clogged. That filter works along with your heating and cooling systems to capture dust, dirt, and other contaminants flowing through your air. But over time, those pollutants can clog the filter. That can block airflow, put unnecessary stress on your HVAC systems, and even cause them to break down.
To keep air moving and your family comfortable for longer, replace your air filter every one to three months. Or, if you have a high-efficiency media filter, change it every six to 12 months.
Low or Leaky Refrigerant
Refrigerant is a liquid-like substance that essentially powers your cooling system’s ability to create cold air. So if your A/C is blowing warm air, it could be due to low or leaky refrigerant. If that’s the case, call in the experts at New Berlin Heating to help you—the sooner the better.
Broken or Dirty Parts
This is the hardest problem to diagnose because you need a professional to open the system and look inside. It could be a dirty condenser coil—a part that helps release heat outside your home—causing warm air to circulate inside. Or it could be a broken belt or blower that’s making your house much warmer than it should be. Either way, trust New Berlin Heating to help you pinpoint the problem and make a long-lasting repair.
