AC Blowing Only Warm Air? Learn How to Correct the Issue.

Nothing’s worse than noticing your air conditioning system is blowing warm air during the long Florida cooling season. Luckily, the problem may be caused by some simple issues, which you can remedy on your own. Listed below are some of the steps you can take to deal with an AC blowing warm air before calling an HVAC repair company.

Check the Thermostat Setting

Unbelievable as it may sound, your air conditioner may be blowing warm air because someone incorrectly set the thermostat to “heat.” Start by ensuring that your thermostat is set to cool. Also, check that the fan setting is on “auto.”

Change Your Air Filter

A clean filter is critical to maintaining healthy airflow through your air conditioner. If your filter is clogged with dust and debris, the airflow to the AC coil is reduced. This can result in your AC blowing out warm air. If you’ve neglected to change your filter, that could be the culprit. Change your filter once every month during peak summer use.

Inspect the Condenser

Your outdoor condenser unit won’t work efficiently if there are leaves, grass, dirt, and other types of debris on or around it. Inspect it for debris. If you see any visible obstructions, turn off the unit and remove the debris. Your unit should then start blowing out cold air.

Check the Circuit Breaker

Your condenser could lose power due to a tripped circuit breaker. Check if its breaker has tripped, and turn it on if it has. Wait to see if your unit will now blow cool air.

Problems That Require Professional Attention

If the circuit breaker trips again after you’ve reset it, you’ll need to call an AC professional to investigate the cause. Your condenser or the entire cooling system may require replacement.

Other troublesome problems that will require the services of a professional include:

If your DIY steps don’t resolve the warm-air issue, be sure to contact a qualified HVAC pro to repair the problem. If you have an AC blowing warm air in Martin, Palm Beach, or Indian River county, contact the NATE-certified technicians at NisAir Air Conditioning for fast diagnosis and repair services.
