Common Air Conditioning Problems

Below we explain several common air conditioning problems (Part 1 of 2) to help you understand what may be happening, if your AC is not functioning properly.

Refrigerant Leaks

If your AC is cycling on and off more frequently than usual, or is having trouble achieving the desired temperature, you may be dealing with a refrigerant leak.

To generate cool air, your AC takes in hot air and runs it across the evaporator coil. The evaporator and outdoor condensing coil are connected with copper lines filled with refrigerant that chill the evaporator coil, which in turn chills the air being pulled across the coil.  Then, the blower motor circulates the chilled air throughout your home’s duct system, making its way out the vents.

When your refrigerant levels are low, your AC struggles and cannot produce the required amount of cool air, so it cycles on and off trying to resolve the issue. This constant cycling is its attempt to achieve the set temperature to keep you cool.  However, if not repaired, this cycling can lead to other problems.

Dirty Air Filter

Your air filter has a vital purpose.  Its job is to keep the inside of the air handler clean and your indoor air quality clean. It does this by filtering dust and other particles before it begins circulating throughout your home.  If your air filter is clogged, it stops the cold air from entering your home, resulting in higher temperatures indoors.

What most people don’t realize is air filters can only do their job for a limited time before they get clogged or dirty. We recommend replacing air filters monthly. However, if you have 5″ pleated filters, we recommend replacing every 3 months.

Clogged Drain Line

Your air conditioner drain line has an excess of water flow throughout the year in SW Florida. Over time, the drain line can get clogged with algae and dirt. This can lead to drain pans overflowing, or water pooling around your air handler.
