Here Is Why Your AC May Be Blowing Hot Air


me with it. That’s perfect for the outdoor activities you may have planned, but if you need to work indoors, that heat and humidity can make things difficult.

Fortunately, we have air conditioners now to take care of that problem. However, when air conditioners don’t work the way they’re supposed to, you need to rectify the situation as quickly as possible.

The last thing you want in the summer is for your AC to act as a furnace, blowing even more hot air into a home. But there are a few reasons why this might be happening, and we go over the more common causes.

The AC Is No Longer Receiving Electricity

Anyone that has an HVAC system in their home enjoys the integration between a furnace inside the home and the AC condenser outside the home. The furnace you have in your home still operates during the summer.

It’s the furnace fan that pushes the cooled air from the condenser throughout the home’s ventilation.

So, if your furnace is still doing its job and blowing air through your home, it’s the condenser that may not be working.

If you’ve had a power surge recently, check your condenser outside.

If the fan isn’t working, this probably means no electricity is going to your condenser.

Check your breaker box to see if the switch for your AC has been tripped.

If the switch is in the off position, just flip it back to the on position and your problem will be solved.

If the problem continues to happen after that, call a professional to come check it out. There might be a more serious underlying problem.

The Refrigerant Is Leaking Out

Refrigerant is the substance that fuels modern AC systems. When it changes its physical state from liquid into a gas, it draws out all the heat, leaving only cold air.

Today’s AC systems just exploit this in a never ending cycle of constantly converting refrigerant from liquid to gas and back again, then pumping the remaining cold air to your home.

Usually, you don’t have to worry about running out of refrigerant since it’s not burned up as a fuel like gasoline, it just changes state repeatedly.

But if a mechanical defect or some accident outside pierces the area where refrigerant is stored and used, the leakage will have a critical impact on your AC’s ability to cool.

There Is Ice on Your Condenser

It’s not common to see a giant ice cube sitting in front of someone’s house during the hottest days of summer, but that can happen to your condenser.

If you inspect it, you’ll find that it’s covered in ice and icicles.

There could be any number of issues behind this, such as leaking refrigerant, a mechanical problem, or even a blockage in the air flow.

The result, however, is the same.

All that cool air being generated by your condenser is staying at the condenser not being pumped to your furnace.
