My AC is Blowing Warm Air

My AC is Blowing Warm Air

Envision coming home after a long day, where you find your AC blowing warm air rather than cooling the house. You need to identify the causes immediately and get them repaired.

The Common Reasons Why Your AC is Faulty Can Include:

  • Inaccurately Calibrated Thermostat

Setting the thermostat accurately can cause the AC to blow hot air. For example, if you set the AC on heat mode, it will generate warm air. Also, warm air will come out from the unit if the blower fan is set on.

Solution: Check the thermostat whether the heat mode or blower fan is set to ON.

  • Leakage In Refrigerant

Refrigerant is responsible for absorbing heat from the air, thereby cooling your room. A leak in refrigerants will decrease the cooling agent.

Solution: Never try to fix the leak yourself. Search for air conditioner installation near you or call us at (714) 894 6500. A leaking refrigerant is a safety concern, and it is the expertise of an HVAC technician.

  • Return Vents Are Closed

If you have closed the top return registers, it is likely to sink cold air and increase hot air generation into the room. Closing the return vents means the hot air is not sent back to the HVAC unit for cooling.

Solution: Take a toll on your house and examine if all return vents are open. One simple task is to hold a tissue six inches away from the vent. The tissue will be pulled into the return vent if it is available.  

  • Dirty Air Filters

Airflow issues are common if the air filter is dirty. It may lead to overheating the fan motor, thereby increasing energy usage.

Solution: Visual inspection is recommended. Also, clean the air filters every two weeks and, if possible, replace them every 3-4 months.

  • Frozen Evaporator Coils

If extensive water aggregates on the evaporator coil, it usually freezes. This restricts heat transfer that blows warm air into the room from the AC unit.

Solution: Don’t turn on the AC if you find ice or frost on the evaporator coils. Let them thaw in the open air, or you may use a hairdryer over the coils to dry them quickly.

  • Dirty Condenser Coil

The condenser coil helps release the hot air from the room to the external environment. The AC’s outdoor unit attracts dust and debris to gather on it. When it is difficult to expel the heat outside, it is likely to blow hot air into the room.

Solution: After turning off the unit and circuit breaker, remove the condenser cover. Examine to see any dust or debris and remove those with a soft-bristled brush.
