Why Is My Air Conditioner Blowing Hot Air?

After enjoying a hot summer’s day here in California, the last thing you want to come home to is a sauna.

Unfortunately, your air conditioner (AC) is doing the exact opposite of its job—blowing hot air. Yikes!

Several factors could be at play. Before paying for a repair, consider your AC system’s age. If it’s 15 years or older, it may be more cost-effective to buy a new unit.

Upgrading to a new efficiency model could instantly cut your utility bills in half, according to the U.S. Department of Energy (DOE). Do you need a replacement? Let one of our specialists at Carrier Cooling Center Dealers specialist take a look at your current system.

However, if your San Diego air conditioner is newer and hasn’t had recent issues, here’s what could be going on:

Wrong Thermostat Setting
Perhaps a member of your household was fiddling with the thermostat and made the target temperature too high. Sometimes, the fix is simple!

Wrong Thermostat Location
Alternatively, your thermostat may be having issues producing an accurate temperature reading. The culprit could be the location—installing a thermostat near an oven or in a room that tends to be warmer or colder than the rest of the house will skew the temperature reading.

There could also be a bug in the thermostat itself. Your specialist can move or re calibrate it as needed.

Clogged Air Filter
Heating, ventilation, and air conditioning (HVAC) system tend to get cranky if you don’t regularly change or clean the air filter. Dust and debris can form a barrier that stifles the airflow needed to cool your home. If your filter needs a change, don’t put it off. Dirty filters can cause mechanical damage to your AC and shorten its lifespan.

Lack of Connection
Your air conditioner has two main components: the indoor unit and the outdoor compressor. Always be sure your outdoor compressor is on and creating cool air for the indoor unit to circulate. Check your circuit breaker for any shortages.

Condenser Coils Are Dirty or Frozen Up
When moisture forms on the outside of your AC, it turns into ice which can impair functioning. This problem is called a freeze-up. Inspect your outdoor box unit for thin ice patches on the condenser coil.

If you notice ice or dirt, this is probably the culprit. The condenser coils circulate the refrigerant that cools your home. When they don’t work, the indoor fans will end up circulating regular, untreated air.

Mechanical Problems
If it’s not one of the previous five issues, there is likely something going on with your air conditioner’s internal parts. There could be low refrigerant levels, electrical problems, or a damaged compressor. If you suspect any of these could be the case, it’s best to call your HVAC specialist for diagnosis.
