If your air conditioner is running but the house is not getting colder, you most likely have a refrigerant leak. The reason for this is because over time, the pipes and valves are constantly compressing and the pressure causes cracks. These cracks grow over time and the refrigerant leaks out slowly. This issue is easily fixed but it requires a professional to determine where the leak is coming from.
Dirty and Clogged Unit
Any air conditioner works best when it is cleaned and maintained consistently. This means you clear out the area surrounding the unit, especially if it’s outside, wipe the condenser free of any dirt or grime, and switch out the filters. If you do not do proper care for your air conditioner unit before using it, it can overheat and cause other parts in it to break.
A sign of a broken thermostat can be your air conditioner unit working perfectly fine one day and then breaking down the next. Its job is to regulate the temperature in your home and when it reaches a certain temperature, it will shut off. However, over time, thermostats will wear out and need to be replaced.
Drain Line is Clogged
Another part of your air conditioner unit that needs to be maintained is the drain line. This piece of your unit drains any moisture that builds up around your unit. It can get plugged up with debris or mold, which results in the water backing up into the air handler. The drain line can be easy to clean and one good tip is to run vinegar or water with bleach through the line every couple of months. This should kill any mold and clear out any debris buildup.
