Why Is My Air Conditioning Unit Blowing Hot Air?

When battling the summer heat, you need high-quality air conditioning to keep your home cool and comfortable. What if your air conditioner cannot cool the house properly and starts blowing hot air instead? Is your air conditioner blowing hot air for a simple problem you can fix yourself, or do you need to call Lancaster HVAC contractor?

Common Reasons For an AC Blowing Warm Air

There are various reasons why an air conditioner might not blow cool air. Listed below are a few reasons that might need your immediate attention. At Brock Heating & Air Inc, We offer AC repair Lancaster CA at an unbeatable price. Our main motive only is customer satisfaction.

Clogged Air Filters

Air filters are responsible for catching all types of airborne pathogens and particles. Though they help to clean the air in your home, they become saturated over time. When the air filter becomes clogged, the airflow is restricted, and cold air cannot circulate properly in the house.

Refrigerant is Low

The refrigerant is responsible for absorbing heat from the air into your house. If it leaks, your air conditioner has a problem cooling your air. You can see that the refrigerant leaks when ice forms in the indoor and outdoor air conditioners. To solve the problem, you need to fill it with refrigerant. The best way to prevent the air conditioner from blowing warm air is to repair it twice a year.

Leaky Ducts

If the duct system in the house has a large enough leak, warm air can flow out of the vents. House ducts send cold air everywhere, but leaks can mix warm air with chilled air, allowing warmer than normal air to flow out of the vents. A specialist should always address duct-related problems.

Dirty Condenser Coils

One of the condensation unit’s important functions is to release heat outside the building. The condenser coil is responsible for this task. But if the coil is dirty, it prevents the system from cooling effectively, causing the air conditioner to blow in warm air.

Malfunctioning Compressor

Your air conditioner relies on a refrigerant that circulates in the unit to blow cold air when it is on. If the unit’s compressor is not functioning, the refrigerant will not be able to change from gas to liquid and will not be able to cool the air.
