Almost 100 million homes in the US have an air conditioning system. However, it is not a guarantee that all these homes have functioning AC systems. Most of the time, people tend to ignore the importance of maintaining a working air conditioner.

While some are ignorant, others are not aware of the essential maintenance requirements. Here is a quick guide on how to identify issues and repair your AC as part of the maintenance process.

How to Identify Issues

If your AC fails to deliver optimal performance, it can mean that various parts may be having issues. The parts to consider checking include:

• Expansion valve
• Compressor
• Refrigerant
• Condenser
• Evaporator coil

However, before checking the parts mentioned above, certain things might happen that can mean your AC has issues. They include the following.

When It Gets Hot Indoors

The evaporator contains a refrigerant that absorbs heat. If you notice warmer temperatures than usual, your evaporator coil could be having issues. In case it gets hotter than you would like, look at it.

Failure to Turn On

This is very common and straightforward. If your AC fails to turn on, it could result from a blown fuse or a circuit break.

Poor Airflow

If you don't regularly clean your AC, your air filter may accumulate dirt and get blocked. This may lead to poor airflow from the cooling vents.

Noise

A functional AC will have normal noises such as the whir of the fan. But, if you hear loud vibrating noises, it can mean your AC has issues and should get checked.

How to Repair Issues Your AC May Have

If your AC fails to turn on, check that the thermostat is not set to the OFF position. You can also check that all switches are turned to the ON position. You can fix poor airflow by cleaning the air vents regularly. If it is beyond cleaning, consider replacing it.

There are some repairs you cannot do on your own. You might require the help of a technician. For instance, if your AC has a long compressor cycle, you should hire an expert to test the compressor.

If your AC produces loud noises, this is a simple issue to fix. You can review the instructions manual, which highlights how to install the system properly. If you missed a step, this could be a reason for the loud noise.

If your AC produces more hot air than usual, clean the air filters and have an expert check the refrigerant's functionality.

Know when and how to repair your AC for better efficiency. The above guide can help you remain calm if your AC fails to work when the climate becomes unfavorable.
