5 Common Problems That Cause an AC System to Blow Hot Air

5 Issues Causing Your AC To Blow Hot Air

Few things are worse than having your AC blow hot air on a scorching summer day in Los Angeles. While this is a frightening thought, it is also a reality. Many AC owners struggle with the problem of hot air blowing from their units.

Before booking a new AC installation in Daytona Beach, FL, you should look for these signs. If you find any of the following issues, have them repaired as soon as possible or get a new one installed right away.

Dirty Air Filters

Filters in AC systems collect dust and debris, forming a top layer on top of it. When this happens, the system will no longer be able to circulate the cold air in your house. The unit will eventually malfunction if left uncleaned, causing it to work harder and harder.


The condenser unit is part of the outdoor HVAC system. A malfunctioning condenser coil or unit results in hot air being blown out of the system. There is a little noise from the condenser while it is working. If there is major chaotic noise, call for AC repair immediately.


Your air conditioner’s coolant or refrigerant is responsible for blowing out cold air. Your air conditioner will blow hot air whenever there is a leak, it is possibly caused by cracks or corrosion in the coils.

Dirty Evaporator Coil

Evaporator coils cool your house by absorbing all the heat and circulating cold air instead. With time, dust and debris collect in these parts of your air conditioner. Resulting in little to no cool air being circulated.

If you are careful with the equipment and follow the required protocol, you can clean your evaporator coils yourself, but it is best to have a professional do it. Get in touch with a professional for AC repair in Ormond Beach, FL.


Air conditioner produces cold air by using refrigerants. This refrigerant collects all the humid air, compresses and converts it into cool air then distributes it. The procedure is adversely affected if the device blows hot air because of a malfunctioning compressor.

Refrigerant Leaks

A refrigerant such as Freon, is under pressure to cool the humid air. A refrigerant leak occurs whenever there is corrosion or cracks in the coils or equipment. As a result, the device blows hot air instead of cold air.

Duct Leaks

Any cracks in your ductwork, no matter how small or large, can allow warm air to enter your home. Cold air is distributed throughout the house through these ducts. Hot or warm air comes out of these vents when warm air enters these ducts.

Thermostat Temperature

Make sure the AC thermostat is set to cool mode if it is on. Ideally, it should be 5 degrees cooler than the room temperature. It is possible to reset the thermostat temperature if the temperature settings are incorrect.

You should look for a new thermostat that is programmable if temperature fluctuations have become repetitive. The rapid increase in heat results in improper AC cooling and hot airflow if you keep your windows and doors open. It is therefore advisable to keep the windows and doors closed.
