My Air Conditioner is Not Blowing Cold Air

My Air Conditioner is Not Blowing Cold Air

It's frustrating entering your home and finding your air conditioner blowing hot air. You’ve come to count on your AC system, and now it has failed you when you needed it most. When this happens, you will want to get your unit back up and running as soon as possible. You will need to call in an HVAC professional, but, before you do so, there are a few tips you can try yourself.

The Thermostat

Check the thermostat on the indoor unit. If it is“on”, then the fan will blow hot air even when the cooling system is not engaged. This makes your air conditioner seem broken. Switch the thermostat to “auto,” so that the fan only blows cold air when you need the system to.

A Dirty Filter

If your thermostat is on “auto” and your air conditioner is blowing hot air anyway, try checking the unit’s filter. If it is completely dirty, then it is time to replace it. The new filter will likely get the air conditioner working again.

Blocked Outdoor Unit

The next thing to check is the outdoor unit. This contraption helps to expel the hot air from your house. If dirt or debris covers it, then it will not be able to work right. Try cleaning it off to see if that improves the performance of your air conditioner.

A Tripped Breaker

The last possible problem you can check on your own is a tripped breaker. A tripped breaker on the outside unit will cause the air conditioner to blow hot air into the home. Switch the breaker on again, and everything should return to normal.

Problems That Need an HVAC Professional

If all these measures fail, then it is time to call an HVAC professional. Your air conditioner is suffering from one of many potential problems. These include a refrigerant leak, leaky ducts, or a bad compressor.

Another potential problem is a broken or unconnected return duct. This will cause your AC unit to draw warm air from outside or the attic. This is an issue that a HVAC professional will be able to check for and repair.
