It's the middle of summer and the last thing you want is for your air conditioner to stop working. You rely on it to keep your home cool and comfortable, so when it's not doing its job, it can be a real hassle. What do you do when your air conditioner is running but not cooling? There are a few possible reasons why your AC unit might be having trouble cooling your home. This article will take a look at five of the most common reasons why your air conditioner isn't working properly and why you need to seek air conditioning system repair services.

1. Thermostat Issues

If your AC unit is turned on but the thermostat is set to "off" then your unit won't run. Similarly, if the thermostat is set to "cool" but the temperature is already at or below the desired setting, then your AC unit won't turn on. Sometimes the wiring in the thermostat can become loose, which will cause the unit to run but not cool. If you're not sure how to fix this problem, it's best to call a professional to repair the wiring.

2. Refrigerant Leaks

If your air conditioner is low on refrigerant, it will run but not cool properly. The refrigerant helps to cool the air as it circulates through the unit. When there's a leak, the refrigerant level drops and the AC unit has to work harder to cool the air, which will result in higher energy bills and wear and tear on the unit. If you think your AC unit might have a refrigerant leak, it's best to call a professional for repair services.

3. Frozen Evaporator Coils

When the coils are frozen, they can't properly absorb heat, which means your AC unit won't be able to effectively cool your home. To fix this problem, you'll need to thaw out the coils and then clean or replace the air filter. You may also need to add more refrigerant to the unit. This task should be done by a professional AC technician.

4. Your Equipment Is Wrongly Sized or Installed

If your AC unit is too small for the space it's cooling, then it will have to work overtime to try to cool the area, which can lead to decreased efficiency and shortened lifespan. Additionally, if your unit is incorrectly installed, it won't be able to function properly. This is why it's so important to have a professional install your AC unit. They'll ensure that the unit is the proper size and that it's installed correctly so that it will work efficiently and last for many years.

5. You Have Leaky Ductwork

If your ductwork is leaky, then conditioned air can escape before it has a chance to reach your living space. This not only wastes energy and money but also makes your air conditioning unit work harder than necessary. To fix this problem, you'll need to have the leaks sealed by a professional.
