How To Perform a Diagnosis On Your Home’s Central AC Unit

Are you in need of AC repair? If so, you are not alone. Many people find themselves needing AC repair at some point or another. Many things can go wrong with your central air conditioning unit. Fortunately, most of them can be repaired by a qualified technician if you know where to look. This post will go through some of the most prevalent issues with your air conditioner and how to address them. Keep reading for more information regarding central air conditioning repair.

Why is central AC running but not blowing air?

If your air conditioner is operating but not blowing, it may be due to various issues. The most prevalent issue is a dirty filter. If the filter is dirty, it will restrict airflow and prevent the unit from cooling correctly. You can clean or replace the filter as needed.

Another common issue is a blocked evaporator coil. The evaporator coil is concerned with absorbing heat from the air within your house. If it becomes blocked, it can cause the AC unit to blow warm air.

The compressor is likely a problem if your AC unit is still not blowing air after checking the filter and evaporator coil. This compressor is responsible for circulating refrigerant through the unit to absorb heat inside your home. If your air conditioner is not operating correctly, it will not be able to keep your house cool.

How can you realize if your air conditioner thermostat is faulty?

If your AC unit is not blowing air, the thermostat may be bad. Turn off the AC unit and remove the cover from the thermostat to test this. There should be a small metal switch inside. Use a screwdriver to switch the position of the two metal tabs. If the AC unit turns on when you do this, the thermostat is wrong and will need to be replaced.

Can I replace my thermostat myself?

It is possible to replace the thermostat yourself, but it is not easy. Depending on the type of thermostat you have and the layout of your home, it may be difficult to access the wires and terminals. If you are not comfortable doing electrical work, it is best to call a professional.

How do you unclog an AC condenser coil?

If your AC unit is not blowing air, the condenser coils may be clogged. Clogged coils can restrict airflow and prevent the unit from cooling correctly. Turn off the AC unit and remove the access panel to clean the coils. Use a brush to remove any dirt or debris from the coils. You can also use a hose to rinse the coils if they are very dirty. Let the coils dry thoroughly before turning on the AC unit. If the issue persists, it might be an even more severe problem that needs expert attention.

How can you tell if your central air conditioner requires Freon?

One way to tell if your central AC needs Freon is to check the outdoor unit. If the unit is frosty or icy, the Freon is low and should be refilled. Another sign that your AC needs Freon is if it is not cooling your home as well as it used to. You can also listen to strange noises coming from the unit, indicating that the compressor is not working correctly. If you detect any of these indications, it is recommended that you contact a professional to examine your air conditioner.

If you have any problems we have discussed or a problem not covered in this article, do not hesitate to call an HVAC technician. They will be able to help you assess the issue and make the necessary repairs. While it may seem daunting, you can fix many common AC unit problems yourself with some know-how like you fix your toilet.
