If you have ever been in a situation, when it’s summer time and your AC is plagued with so many problems, you may never want to be in this nightmare ever again. Hence, we have listed the most common causes of AC failure and how you can prevent them so as to never compromise with your summer comfort.
- The evaporator coils are frozen
The evaporator coil of your AC is stuffed with refrigerant and is meant to absorb the heat from the air like a sponge. It may seem a tad bit counter intuitive, but those coils require warm air to circulate in the surrounding areas in order to make them work properly. When something goes awry with the airflow and the evaporator coils get frozen, you may find that a layer of ice is accumulated on the outside. When the ac line frozen, warm air comes or no air comes out of the AC.
- Your AC has low refrigerant
The refrigerant in your AC helps in removing the heat and humidity in the air of your room. When there is a leak in the refrigerant lines, you can end up with low amount of refrigerant in your AC. Unluckily, addressing this issue correctly is not just about replacing the refrigerant. You need to hire an HVAC repair professional to have a look at the leaks and fix the holes in the lines. This may take a lot of time and money particularly when there are multiple leaks.
- The condenser coils in your AC are dirty
The condenser coils of your unit which are the external part of the system eliminate the heat reduced from the air by pushing it outside the building. The condenser coil fails to work well when it is covered with a layer of filth. This is deemed a common issue in every polluted city. When this occurs, the heat transfer is obstructed and your unit is enforced to work harder for the job that further leads to wear and tear in the unit and sometimes may cause system failure.
- The AC fan is having problems
There are two fans in an AC, one that blows indoor air over the evaporator coil to cool the air and another blows the air the outdoor condenser to push the absorbed heat out of the building. When either of the fans fails to work because of lack of lubrication, faulty motor, wear and tear, or accumulation of debris, you have poor airflow and AC problems. When you don’t address this issue, it can cause your compressor to fail, means more problems for your AC.
