Summer is here, and with rising temperatures comes the need for cool, refreshing air. We rely on our air conditioners to keep us comfortable during the hottest months of the year, but what happens when your AC starts blowing warm air instead? It can be frustrating and uncomfortable to have your home suddenly feel like a sauna.
In this blog post, we will discuss common causes of warm air from an AC unit and provide practical tips on how to troubleshoot and resolve these issues.
Common Reasons Your Air Conditioner Is Blowing Warm Air
- Thermostat Issues: A faulty thermostat or one that has been set to “heat” can stop the exchange of air, resulting in warmer air being circulated.
- Clogged Air Filters: Dirty or clogged air filters can impede the airflow of cool air, resulting in lukewarm air being transmitted throughout your home.
- Frozen Evaporator Coil: A dirty evaporator coil will not be able to initiate the cooling process, causing the coil to freeze.
- Dirty Condenser Coils: Dirt, debris, and other obstructions around the condenser coil can make it difficult to draw warm air out of the home.
- Refrigerant Leaks: Since the refrigerant is responsible for cooling the air, low levels or leaks within the system can produce hot air.
- Condenser Unit Problems: Common condenser issues such as faulty wiring or improper voltage may cause the unit to expel warm air.
- Electrical Issues: There may be an issue concerning the power supply to the AC unit. Power overload can trip the circuit or loosen the condenser plug.
Troubleshooting Steps to Rectify the Situation
- Check and Adjust the Thermostat: Ensure the thermostat for the AC unit is working, the “cool” setting is turned on, and the thermostat is reading the correct temperature.
- Inspect and Replace Filters: Remove and clean the air filters to ensure better airflow.
- Examine the Outdoor Unit: Ensure the exterior portion of the AC is not blocked by debris or shrubs, which can reduce the transference of air.
- Check the Circuit Breaker: Check the circuit breaker to ensure it is not tripped and does not need to be reset.
- Call a Professional for Refrigerant Issues and Electrical Problems: If you have concerns about a possible refrigerant leak or an electrical issue, contact a professional AC service.
Preventative Measures to Avoid Hot Air from Air Conditioners
Scheduling regular air conditioner maintenance is important to ensure your unit is in top working order and produces clean, cool air when needed.
To reduce the risk of sudden breakdowns, particularly due to neglected maintenance, schedule inspections before the unit is used every season.
