Why is my AC Unit Blowing Warm Air?

Reasons Why Your AC Unit is Blowing Warm Air

Especially during the hot summer afternoons, having your AC unit blow warm air can be really frustrating. Your living area feels so hot, you will become uncomfortable for the rest of the day. All you get after placing your hand on the AC registers is warm air coming out of the cooling unit.

What has gone wrong with your cooling unit? Do you need to call an air conditioning service expert immediately? When your cooling unit starts to blow warm air, something is definitely wrong with the unit. Bob Heinmiller Air Conditioning Inc., your dependable Orlando Air Conditioning Expert brings you some of the reasons that can make your AC unit blow warm air and possible solutions.

Thermostat Issues

The moment you notice that your cooling unit is blowing warm air, the first thing to check is your thermostat. Your little ones might have accidentally tampered with the thermostat. Your co-worker might have turned it off because of feeling too cold. Ensure that the thermostat is set to cool, with the fan set to auto. After doing this, and the temperature doesn’t improve, guess it’s time to call on your Orlando AC repair expert.

A Clogged Filter

Another thing that can cause your Orlando Air Conditioning unit to blow warm air is a clogged filter. The filter of your air conditioning unit is designed to help remove dust, debris, and contaminants from the air flowing through the cooling unit. Over time, these dust, debris, and contaminants can end up blocking air from entering the system, thus leading to reduced air flow.

When this happens, the coils will be unable to remove the heat. At the end of the day, the fan of your cooling unit will begin to blow heat back into your space. This is why it is advisable to clean your AC filters regularly and change the filters after some months.

Blocked Vents

Unfortunately, you might have closed the vent grilles during the cold winter months and never re-opened them. It is also possible that you have furniture blocking them. Walk around your home or office space. Check to be sure that all registers and returns are open. This will leave room for air to flow freely.

Leaky or Disconnected Ducts

Leaky or disconnected ducts can also cause your cooling unit to blow warm air. In a situation whereby there are holes or cracks in the duct, or if the duct is totally disconnected, return air may be unable to make it back to the cooling unit. At the end of the day, cool air ends up wasting in your walls, while your AC continues to blow warm air. Call your Air Conditioning Repair Orlando, FL expert to inspect the ducts.

Dirty Condenser Coils

The condenser of your cooling unit is responsible for releasing heat to the outside of your home or office. Due to exposure to weather elements, the condenser might become covered with dirt, leaves, and grime. Eventually that the operation of the condenser coils are obstructed. Thus, your air conditioning unit will be unable to cool your home effectively, thereby blowing warm air.

Refrigerant Leak

The refrigerant is the substance which flows through your AC unit, thus, making cooling happen. When there is a leak in the refrigerant coils, the cooling power of your cooling unit is lost. In the long run, your AC unit will start to blow warm air. Call your Air Conditioning Repair Orlando, FL expert to inspect the refrigerant coils, repair the leak, and add more refrigerant if need be.

There you have it! The above are some of the reasons that can make the air conditioning unit in your Orlando, FL, home or office to blow warm air. By carrying out regular maintenance on your cooling unit, you will be able to prevent most, if not all, of these causes.
