Why Is My AC Blowing Hot Air?

As the Las Vegas summer heat intensifies, having a reliable air conditioner is crucial to maintaining a cool and comfortable home. But what happens when your AC starts blowing hot air instead of providing relief? Let's explore the common reasons behind this issue and how to fix it.

Common Causes of an AC Blowing Warm Air (and How to Fix Them)

There are several potential reasons your air conditioner might be blowing warm air instead of the refreshing cool breeze you expect. While some of these issues may require professional assistance, others can be easily addressed on your own.

Incorrect Thermostat Settings

It may seem obvious, but it’s worth checking that your thermostat isn’t set to “heat.” Accidental switches can happen easily, whether it’s from a bump with a bag, playful children, or simple oversight. Make sure your thermostat is set to “cool” if you want cool air.

Another potential issue is the fan setting. If the fan is set to “on,” it will continue blowing air even when the cooling system isn’t active, which can result in warm air coming through the vents. Set the fan to “auto” to ensure it only runs when cooling.

If these settings are correct and the issue persists, you might be facing one of the following problems.

Outdoor Unit Power Loss

Your AC system consists of an indoor unit that circulates air and an outdoor unit that cools it. If your indoor unit is blowing warm air, it could be due to a lack of power to the outdoor unit. This could be caused by a tripped circuit breaker or a blown fuse. Check your circuit breaker or fuse panel; if power isn’t reaching the outdoor unit, a professional will need to resolve this.

Low Refrigerant Levels

Warm air from your AC can also indicate low refrigerant levels, often due to a leak. In such cases, the system struggles to cool your home, continuously running without achieving the desired temperature. Contact URBN Home Services to locate and repair the leak, recharge the refrigerant, and restore your system’s cooling capabilities.

Dirty Evaporator Coils

Evaporator coils are vital for your air conditioner’s performance. If these coils become dirty or clogged with debris, they can’t efficiently cool the air. If you’ve missed your annual maintenance, dirty evaporator coils might be the culprit. Schedule a professional tune-up to clean the coils and restore your AC's efficiency.
