What to Do If Your AC Unit is Blowing Hot Air


Manchester, NH Homeowner Looks for Help

The simplest thing to check when your air conditioning unit is blowing hot air is the thermostat. Confirm that this is set to cool and that the AUTO is not on. This setting ensures that the fan only blows to circulate cool air through the home. If the thermostat settings check out fine, the problem may be a frozen AC coil. This can be caused by a dirty air filter or dirty evaporator coil. The cause of warm air being put through the AC may also be a refrigerant leak in the air conditioning unit. This leak could be preventing the air from getting to a cool enough temperature before blowing into the house.

A homeowner in Manchester noticed that his air conditioning unit was blowing warm air. After confirming that the thermostat settings were correct and still not resolving the problem, he contacted Joyce Cooling & Heating for assistance.

Mechanical Issues that Cause AC to Blow Warm Air

A dirty air filter can restrict air flow, making the AC work harder. This extra taxation on the unit can make it a struggle to maintain a cooler temperature. Your outdoor compressor may also be the culprit. Dirt and debris collecting around this outdoor unit can make its way into the exposed coil through vents or cracks and affect the performance of the air conditioning unit. Be sure that there is at least two feet of room around the condenser to prevent this from becoming a problem.

The compressor is critical to the efficient running of your air conditioning unit. Responsible for circulating refrigerant through the HVAC system, if this fails your air conditioner will struggle to keep the air cool. In this scenario, you may need a replacement air conditioning unit especially if the existing one is very old.

A Joyce Cooling & Heating technician was dispatched to the home in Manchester. After performing a thorough cleaning of the indoor and outdoor air conditioning unit, the homeowner once again has cool air circulating throughout his home.


Testimonials & Reviews

We had central air conditioning installed last year by Joyce and were very satisfied with the job. Today, John N. serviced the unit and all of the components and he was incredibly thorough and professional. He explained exactly what was serviced and what to avoid (greenery around the outdoor unit). I highly recommend Joyce Cooling & Heating!
