Air conditioning problems

We all have the same issues when it comes to our A/C problems, but some are more common than others. Here are some of our most common A/C problems:

The A/C is not cooling my house/apartment.

This is the most common problem that we hear about. There are a few things that you can do to try and fix this problem. The first thing you should do is check your air filter and make sure that it is clean. If your air filter is dirty, it will restrict the airflow to your unit and cause it to work harder to cool your home. The next thing you should check is your thermostat to make sure that it is set to the correct temperature. If your thermostat is set too high, your unit will run continuously and never reach the set temperature. Check your outdoor unit to make sure that there is nothing blocking the air flow.

Air conditioning capacitor failure.

One of the most common issues that we see with air conditioners is capacitor failure. The capacitor is responsible for starting the compressor and fans in your unit. If the capacitor fails, the compressor and fans will not start, and your unit will not be able to cool your home.

Frozen Evaporator Coil.

Another common issue that we see is a frozen evaporator coil. This can be caused by a number of things, but the most common cause is a dirty air filter. A dirty air filter will restrict the airflow to your unit and cause the evaporator coil to freeze. Leaking Refrigerant. Refrigerant is what cools the air in your unit. If your unit is leaking refrigerant, it will not be able to cool your home effectively.

Cool Air Conditioners

Damaged Compressor.

The compressor is responsible for circulating the refrigerant in your unit. If the compressor is damaged, the refrigerant will not be able to circulate and your unit will not be able to cool your home.

Dirty Air Filter.

As we mentioned before, a dirty air filter will restrict the airflow to your unit and cause a number of problems. It is important to check your air filter monthly and replace it if it is dirty.

AC Refrigerant Leak.

If your unit is leaking refrigerant, it will not be able to cool your home effectively. Water Leak (Inside the House). If you have a water leak inside your house, it is most likely coming from your unit. Check the unit for any leaks and have a professional repair the unit if necessary.

Water Leak (Outside the House).

If you have a water leak outside your house, it is most likely coming from your condensate line. Check the line for any leaks and have a professional repair the line if necessary.

Thermostat Malfunctioning.

If your thermostat is not working correctly, it will not be able to control the temperature in your home effectively.

AC Making Noises.

If your air conditioner is making strange noises, it could be a sign of a serious issue.

Circuit Breaker Keeps Tripping.

If your circuit breaker keeps tripping, it is most likely due to a power surge. You should have a professional check your unit to see if there is a problem.

Electrical Failure.

If your unit is not receiving power, it will not be able to turn on. Check your circuit breaker to see if it has tripped. If it has, reset it and see if the unit turns on. If the unit still does not turn on, you will need to have a professional check the unit.

AC Smells Bad.

If your air conditioner smells bad, it could be a sign of a mold or mildew problem.

Leaking Ducts.

If your ducts are leaking, it will cause your unit to work harder to cool your home. Have a professional check your ducts and repair any leaks.

AC Fan Failure.

If the fan in your unit is not working, it will not be able to circulate the air and your unit will not be able to cool your home.

Weak Air Flow.

If you have weak air flow, it could be due to a number of things. The most common cause is a dirty air filter.

Conclusion.

There are a number of common air conditioning problems that can occur. The most common problems are dirty air filters, frozen evaporator coils, and capacitor failure. It is important to check your unit regularly and replace any parts that are not working correctly.
