Why Is My Air Conditioner Blowing Warm Air?

As the temperatures soar and the summer heat becomes insufferable, the last thing you want is your air conditioner blowing hot, uncomfortable air instead of the cool, refreshing breeze you were expecting. This particular problem can be frustrating and uncomfortable, to say the least.

There can be several reasons why your air conditioner is blowing warm air. Let’s review some of these potential causes in more detail below.

Dirty Air Filter

A dirty air filter is one of the most common reasons why your air conditioner is blowing warm air. The air filter is responsible for filtering out dust, dirt, and other debris from the air, preventing them from entering your home. However, when the filter becomes clogged, it restricts the airflow, reducing the amount of cool air that is being circulated into your home. This can cause your AC to blow warm air, or worse, not blow air at all.

It’s generally recommended to change your air filter every three months to prevent it from becoming dirty or clogged. This simple maintenance task can have many benefits down the road and might even help you avoid needing an unexpected air conditioning repair in McKinney, TX.

Clogged air filters are not something to be taken lightly. Learn more about how changing these filters regularly can have a positive impact on your comfort and energy savings:

Thermostat Setting

When you discover your AC blowing hot air, one of the first steps you should take is to inspect the thermostat. As you probably know, the thermostat is responsible for regulating the temperature in your home. If it’s set to “heat” instead of “cool,” your air conditioner won’t be able to produce cool air. It seems like an obvious mistake, but it’s actually an easy one to make — especially when you are not familiar with your thermostat’s functions. Confirm that your thermostat is set to “cool” and not “heat,” and if it is still blowing warm air, check the fan settings.

Dirty Evaporator Coils

Your AC system’s evaporator coils remove heat from the air, cooling it before it is blown back into your home. However, when these coils become dirty, they cannot absorb heat efficiently. As a result, this could be why your air conditioner is blowing warm air.

Dirty evaporator coils are a common problem, especially in homes with pets. You need to schedule regular AC maintenance with an HVAC professional to clean the evaporator coils. This can help to prevent issues and keep your AC running smoothly.

Circuit Breaker

Believe it or not, when you find your AC blowing hot air, this issue could have to do with a tripped circuit breaker. When your AC works, it pulls a lot of electricity, and if the circuit breaker is not robust enough, it can overload.

A tripped circuit breaker can lead to the AC unit not receiving adequate power, causing it to blow hot air. To fix this particular issue, you’ll need to reset the circuit breaker. If it keeps tripping, contact an HVAC professional to install a dedicated circuit.

Refrigerant Leak

Refrigerant is the substance that absorbs heat in your AC system. If there is a refrigerant leak, it means that your AC does not have enough refrigerant to remove heat from the air, and as a result, it recirculates the same warm air that is in your home.

Refrigerant leaks can occur due to wear and tear or damage to your AC system components. An HVAC professional can detect and fix the leak and recharge the refrigerant.

Condenser Coil Problems

The condenser coil is responsible for releasing the heat that your AC pulls from your indoor air. If the condenser coil is not working properly, this can cause your AC system to work harder, which can lead to your AC blowing hot air.

To determine if the condenser coil is the problem, check the outdoor unit. If it’s dirty, it is possible that the condenser coil is clogged with dirt or debris. Cleaning the coil or calling in an HVAC professional to maintain the AC system can solve the problem.
