With the rising cost of electricity, you can’t afford to have an underperforming air conditioning system. If your air conditioner is blowing warm air, it may actually be heating up your home. If you’ve started up your system this spring and noticed that the air coming through your vents is not as cool as you’d like, it may be time to contact an HVAC professional. But first, take a look at the three most common reasons your air conditioner is blowing warm air.

In order for your air conditioning unit to run at its best, the system requires a set level of refrigerant. When this level drops, a number of problems can occur–with warm air being the most immediately noticeable. Most times, low levels are a result of a refrigerant leak, which could mean that components in your system have corroded or been punctured.

You AC unit’s condenser coils absorb and dissipate thermal energy, with the system’s exhaust fan dispersing warm air to the outside. If these coils get dirty, the condensation process loses a great deal of efficiency and may not be able to generate cool air. Even if the system is obstructed, the condenser coils may not be able to operate at peak performance.

First, you’ll want to make sure your thermostat is set to cool (this is a common oversight). If warm air is still coming through your vents, your thermostat may not be assessing temperature correctly, which will provide inaccurate information to your system. This can often be remedied by replacing the thermostat.
This summer, don’t throw money away by cranking up an AC system that blows warm air. If you’ve done annual maintenance on your unit and it still seems to be warming up your home rather than keeping things cool, contact us today for more information.Featured image by o0o0xmods0o0o
