Why Does My Air Conditioner Blow Warm Air?
Whether it’s the first warm day of the year or you’re in the middle of a summer heat wave, having a working air conditioner is essential to your physical health and mental wellbeing. So it’s understandable to be concerned when you come home to find your central AC unit not blowing cold air. Before you panic, learn more about the most common causes behind this common problem and how you can prevent it:
The thermostat is set improperly. Sometimes, when your AC unit isn’t operating the way you want it to, it may be due to an incorrect setting. A quick trouble shooting exercise can help you ensure that the unit is on the “cool” setting, not “heat.”
Your air filter needs to be changed. Most experts recommend checking filters on a monthly basis during periods of consistent use and changing them if they become dirty. A dirty air filter can lead to blockages and pressure fluctuations that cause an air conditioner to blow warm air.
Your condenser coils are blocked. The part of the AC unit that’s located outside is known as the condenser. When the coils inside the condenser are blocked, it impedes airflow and the ability to effectively cool air. A visual inspection and thorough cleaning of the outside unit should be performed on a regular basis throughout seasons of steady use.
The condenser breaker is tripped. The outsider condenser has a separate breaker than the inside air conditioning components. When you have an AC blowing air but not cooling, the outside breaker may have been tripped and needs to be reset.
You have a Freon leak. If there’s a leak in your system that’s allowing refrigerant to escape, the levels will dip and your unit will become unable to absorb heat from the air. A side effect of not having enough Freon flowing through the system is an air conditioner that blows warm air.
What to Do When Your Central AC Unit Isn’t Blowing Cold Air
If an AC is blowing air but not cooling it, there are several easy fixes such as adjusting the thermostat or resetting the condenser circuit breaker. However, if you notice a persistent problem or have identified a serious concern such as a refrigerant leak, it’s helpful to seek professional assistance. Contact the HVAC specialists at N.S.
