AC blowing warm air out of vent

Why Is My AC Heating My House in Cleves, OH?

June 28, 2025

When you turn on your air conditioner, you expect cool, refreshing air to come from your vents. If that’s not the case, and your air conditioner is making your home hotter, something is definitely wrong. Here’s a look at a few reasons for your AC to blow hot air in your Cleves, OH home.

Dirty Air Filter

You’re probably aware of how a clogged air filter can diminish your indoor air quality, but you may not know that it can also lead to your AC producing warm air. When your air conditioner faces added strain while trying to push air through a clogged filter, it can get warm internally. This often leads to the air not being as cool as it should when it gets into your home.

Condenser Issues

The condenser is a component in your outdoor unit that’s responsible for releasing heat that comes from inside your home. When something blocks the condenser or its coils become coated with dirt, the system can’t release that heat. This leads to your AC blowing warm air, as the heat has nowhere to go.

Faulty Compressor

Your air conditioner relies on a condenser to put the refrigerant under high levels of pressure. When something goes wrong with the condenser, the refrigerant can’t adequately cool the air that blows into your home. In the most extreme cases, this can lead to your air conditioner producing warm air instead of cool air.

Refrigerant Leak

Your air conditioner relies on refrigerant to cool the air that flows through your vents. This refrigerant travels through a network of coils, and if those coils suffer damage, a leak can occur. When you have a refrigerant leak, you need professional repairs, as it’s not safe for untrained individuals to handle this substance.
