AC Troubleshooting: Why is my AC not Cooling?

Why Is My AC Not Cooling?

Is your AC not cooling? If that answer to that question is yes, then you may be frustrated. Air conditioners are complex systems. That is why it may be difficult to find out why you have an air conditioner not cooling. There are several things that can cause your air conditioner to stop cooling.

Frozen Air Handler

If your AC not cooling, then your air handlers may be to blame. The evaporator coils can become frozen. The ice will prevent the air from flowing. AC troubleshooting is typically easy. If you keep the air conditioner off for 24 hours, then the evaporator coils will likely thaw out on their own.

However, if you still have this problem, then you will need to call a technician. Your evaporator coils may need to be cleaned. A professional has specialized tools that can clean the coils.

Thermostat Set to On

You should check your thermostat if you have an air conditioner not cooling. If the fan is set to on, then it will run 24 hours a day, seven days a week. It will run even when the air is not being cooled. That is why you will need to set the thermostat to auto.

Faulty Compressor

The compressor is a part of the air conditioning system that is part of cooling. It compresses the refrigerant or coolant and then circulates through the evaporator coils and condenser. If your compressor is damaged, then it will not be able to keep your home cool.

Dirty Coils

Your condenser helps dissipate the removed heat. If the coils are dirty, then the heat will not be dissipated. The efficiency of the air conditioner will also be reduced. That is why dirty coils will need to be cleaned. You will need to have a professional to clean the coils.

Dirty Air Filter

Your air filter has to be changed on a regular basis. If the air filter is dirty, then the air conditioner will not work as efficiently. Your air conditioner may struggle to circulate the air. The evaporator coil may also start to freeze up.

Low Refrigerant Levels

Your air conditioner will not work properly if the refrigerant level is low. The refrigerant cools the air that flows through the evaporator coils. There are several things that can cause the refrigerant level to drop.

There may be a coolant leak. Frequent usage can also cause refrigerant levels to drop.

Undersized Air Conditioner

Many people make the mistake of buying an air conditioner that is too small for their home. Some people will buy an air conditioner based on their budget and not their needs. It is important to look at all of the proper sizing parameters before you buy a new unit.

The climatic conditions are another thing that you will need to take into consideration. An HVAC technician will help you pick an HVAC unit that is the right size for your home.

Your Air Conditioner Degrades Over Time

Your air conditioner is like any other electrical equipment. It will start to degrade over time. According to the Heating, Refrigerating and Air Conditioner Engineers, air conditioners will lose seven percent of their efficiency within the first year. They will lose five percent during the second year, and an additional two percent every year after that.

Frequent maintenance can slow down the rate at which your air conditioner ages. You will also need to get minor problems repaired before they become serious ones. If you need help with AC troubleshooting, then you will need to contact an HVAC technician. Our experienced technician will solve the problem as soon as possible.
