There is absolutely nothing more uncomfortable than sitting in your home and coming to realize that your air conditioner is not only not cooling your home, but in fact blowing hot air.   Even worse is if it is during the sickeningly hot summer months.

It is best to deal with the issues prior to the dog days of summer, you don not want to be looking for answers for why your air conditioner is not working when you and your family are burning up inside your home. It is, of course, always best to know the reasons ahead of time so you will know how to avoid them and/or when to call the professionals at HVAC Philly, who have been serving the greater Philadelphia, Bucks and Montgomery County, PA areas for over 20 years,to fix the issue.

So why is your AC blowing hot air? Here are the most common reasons:

Your thermostat is turned to heat mode

Although this may definitely be a big hand to forehead moment,  if you are getting hot air, you may just have accidentally flipped your thermostat to “heat” mode. It happens to all of us. If that is the case, switch it back to “cool” and you’re good to go.

Your evaporator coil may be dirty, which is caused by a dirty air filter

Chances are, your thermostat is set to cool, and you’re still getting hot air. Now what?

The cause could be a dirty evaporator coil caused by a dirty air filter. This keeps your air conditioner from properly cooling your home. You can change the filter, but you’ll need a professional to clean the evaporator coil.

Your outside AC unit is not properly maintained

Walk outside and look at your air conditioner’s outside condenser unit. What do you see?

Is there anything blocking the condenser coils air flow? Are they blocked with dirt and debris?

If so, this seriously impacts your air conditioner’s cooling ability.

Cleaning the condenser coils needs to be a regular activity during the summertime.

Low on refrigerant/Freon

This is the usual culprit. Your air conditioner needs a proper refrigerant (usually Freon) charge to cool your home.

So a Freon leak can leave you feeling the heat since you’ll have a complete loss of cold air.

You can tell if your air conditioner doesn’t have enough Freon if ice forms on the inside and outside units.

Getting a Freon charge is best left to a professional.

Get AC maintenance should be done annually

Keeping an eye on these problems will not only will this keep your air conditioner from blowing hot air, it will also prevent a costly breakdown. And the last thing you want is a breakdown during summer.

So it only makes sense to get preventative maintenance done during the spring before it gets too hot.  However life sometimes gets in the way, it is better late than never.  So if you find that you are in need of a professional AC maintenance service, call today HVAC Philly today!
