Why is my Air Conditioner Blowing Hot Air?
You go to bed on a hot summer’s night, basking in the icy breeze from your air conditioner. The next morning, you wake up in a sweat, and realize your AC unit is blowing out hot air! If you find yourself in this situation, there’s no need to panic. Ballard Natural Gas created the following checklist, to help you figure out what’s causing the problem:
Check the Settings on your Thermostat
Sometimes, in the heat of the moment, it’s easy to forget the most basic solutions. Make sure your thermostat is set to “cool” and not “heat.” Additionally, make sure the “auto” section is highlighted. The “fan” setting should be deselected, because this setting causes the fan to run even when the A/C isn’t operating.
Check Your Air Filter
When in doubt, always check your air filter. Clogged air filters are the bane of an AC unit’s existence, and can cause all sorts of problems for the unit. You should replace air filters once a month. This will greatly reduce the risk of any mechanical issues, increase the longevity of your HVAC system, and keep the air quality safe.
Make Sure All Units, Indoors and Outdoors, are Operating Correctly
Check to make sure that the the indoor unit and the outdoor compressor are turned on and functioning. The compressor generates cool air, so if it’s off, the indoor unit has nothing to circulate.
Check for Freeze-Ups
Freeze-ups are the formation of ice on the exterior of a unit. Check the outdoor compressor for any freeze-ups, as they can cause the compression coils to work improperly, leading to hot air being circulated. Dirty coils can lead to system malfunctions as well.
There are a number of more serious issues that can cause the unit to circulate hot air. A few examples are refrigerant leaks, electrical issues, or broken compressors. In these cases, professional help is mandatory, as they are potentially dangerous to your AC unit.
