Why Isn’t My Air Conditioner Cooling My Home?

When summertime hits, the last thing you want to be stuck with is a malfunctioning air conditioner. So when you go to turn in on the first time the weather warms up to discover it’s blowing out lukewarm air, your initial reaction may be to panic and start shopping for a new air conditioner. Before you jump to any conclusions though, be sure to read below to discover some common reasons that your AC might not be cooling. Sometimes it’s as simple as a quick repair!


It’s no secret that when you live in a home with multiple occupants, people may have different cooling preferences. When this is the case, quite often other people will mess with the thermostat. Be sure to check that nobody has changed the temperature setting on your thermostat, and also that the thermostat is set to “cool” rather than “auto.” If it’s set to auto, then the fan may run but you won’t get any cooling effect.


Whether your ductwork has a small hole or tear in it, is bent, or even wasn’t installed correctly to begin with, it cannot deliver the conditioned air that it is meant to. Additionally, breached ductwork makes your air conditioner work harder to achieve proper cooling. An inspection and possible duct sealing may likely be necessary.


Upon installation, your air conditioner is supplied with enough refrigerant to last its entire lifespan. However, occasionally damage or corrosion occurs that causes a refrigerant leak. If this happens, your AC will not be able to deliver cool air. A refrigerant leak should be taken care of right away to prevent further damage to your system.

Condenser Coils

A blown fuse or even a tripped circuit breaker can prevent your condenser coil from working, even though the fan will continue to run. This will make it appear as though your air conditioner is operating, but just not blowing cool air. If you suspect you have a problem with this or any of the above mentioned issues, give us a call for quick repairs.
