Common Problems Your A/C May Face

June 1, 2022

A broken air conditioner is a common experience for many homeowners. Being aware of the causes of air conditioner failure can help you develop the necessary strategies that will keep your system in the best shape. These common causes of AC failure can guide you on how to go about it.

1. Frozen Coil

A frozen coil is not usually an everyday occurrence. It happens when the air conditioner is used for long periods without being serviced. The frozen coil will not be able to function properly, and this will cause the entire system to fail. You can solve this problem by simply thawing the coil with a hairdryer. Once the coil is thawed, you should replace the filter and turn on the fan to circulate the air.

2. Clogged Drain Line

The drain line is responsible for draining away all the water that condenses on the evaporator coils. If this line becomes clogged, it will cause water to back up and overflow into the home. This can be a serious problem because it can lead to water damage. You can prevent this problem by regularly cleaning the drain line.

3. Dirty Air Filter

Air filters get dirty with time and need to be replaced. A dirty air filter will restrict airflow and cause the system to overwork. This will lead to a decrease in air conditioner efficiency and an increase in your energy bills. Therefore, it is important to check the air filter regularly and replace it. You can replace the air filter yourself or hire a professional to do it.

4. Leaking Refrigerant

Refrigerant leaks are one of the most common problems that air conditioners face. When the refrigerant leaks, it will cause the system to lose its cooling power. This problem can be fixed by simply repairing the leak and replenishing the lost refrigerant. Therefore, it is important to check for leaks regularly and have them repaired as soon as possible.

5. Thermostat Issues

The thermostat is responsible for controlling the temperature in your home. If it is not working properly, it can cause the air conditioner to overwork or underwork. This will lead to an increase in your energy bills. Therefore, it is important to have the thermostat checked regularly and replaced if necessary.


These are some of the most common problems your air conditioner may face. By being aware of these problems, you can develop the necessary strategies to prevent them. Remember, an air conditioner is a major investment, and it is important to take care of it to last for many years. Contact JMB A/C & Heating LLC for all your air conditioning repair needs.
