5 Common Reasons for AC Trouble

It can be a frustrating experience to have your AC stop working when you need it, such as during hot summer days or when you have house guests. Although there are countless reasons why your AC has stopped working, there are also a handful of common AC problems that can explain why your AC has blown out.

1. Poorly Installed
When an AC unit has been improperly installed, it can cause leaking air ducts and poor air flow. It can also cause fires if the wires were incorrectly installed. This is due to poor wiring that prevents the AC from receiving power or a tripped circuit breaker. If you’re unsure about your AC being poorly installed, an indication can be the sound of loud rattling or vibrations when you turn on the AC system.

2. Low Refrigerant Levels
Refrigerant is a chemical used to cool air. If the refrigerant levels are low, this could mean that there’s a refrigerant leak somewhere. When a refrigerant leak occurs, it can cause your AC to not bring cool air into your home. A common sign of a leak is when the AC unit needs to be refueled with refrigerant.

3. Outside Fan Stopped Running
The outside fan in the AC unit is responsible for taking hot air out of your home. When the fan stops working and the heat in your home doesn’t transfer outside properly, the system can overheat and cause damage to the AC compressor.

4. Stalled Condenser Coil
The condenser coil is the area of the AC unit that produces cold air. If your AC turns on normally but doesn’t produce cool air, this can mean that your AC system has a stalled condenser coil. Possible causes of a stalled condenser coil can be a tripped circuit breaker or blown fuse.

5. Air Filters Clog Up
When the AC air filters are clogged, this can cause the system to not cool your home due to obstructed air flow. If you have pets or plants, this can cause your air filters to clog up faster than normal. Depending on your environment, the air filters in your AC unit can be clogged up, and it can require you to replace them every 3-5 months.

Although there are several common AC problems, you can hire a professional to check your AC system for any other issues.
