Why is Your AC Blowing Out Warm Air?


Even though your air conditioner appears to be working, being unable to cool down on a hot day is quite annoying. There are several probable reasons why your air conditioner is spewing warm air. Understanding the most common causes of air conditioner problems might help you prevent this inconvenience. You may take precautions to avoid these setbacks at your home or company. Your air conditioner, like all other equipment, should be examined and cleaned on a regular basis to avoid problems.

Examine Your Thermostat

The thermostat is the first thing to check if your home or business air conditioner is blowing warm air. True, they’ve been tampered with by children accidentally hitting them with flying objects or a coworker inadvertently turning them off because they’re too chilly. Be certain that you have the thermostat set to COOL and that the fan is turned on.

Low-Temperature Refrigeration

When your unit’s refrigerant level is low, it may blow warm air. A refrigerant is required to keep your equipment running efficiently. If your air conditioner isn’t cooling, it’s possible that the refrigerant is leaking, and what’s left isn’t enough to keep your home cold.

Dirty Air Filters or Evaporator Coils

Another possible source of warm air from your AC unit is a problem with the evaporator coil. The coil’s job is to collect heat from the air within the air conditioner. It will not absorb heat efficiently if it is damaged or dirty, causing the AC to blast warm air. Finally, a blocked air filter might be the source of your air conditioner’s warm air. Before entering the air conditioner, the air filter removes debris and particles from the air. If it is dirty, it may obstruct airflow and cause the AC to blow warm air.

Examine Your Ductwork

If your energy bills are soaring this summer, have your ductwork examined. There might be an undiscovered leak, which is usually caused by rats or negligent installation workers. Ducts run through your home’s walls and ceilings, bringing cooled air from your air conditioner to the rest of the space. When there are openings in the ducts, air leaks into the walls, which is undesirable.

The Outside Air Conditioning Unit’s Power Was Turned Off

Standard components of air conditioning systems are an interior evaporator/air handler unit and an outside condensing unit. The fan will continue to blow air into your space as long as the air handler is turned on. However, no cooling will occur if the condenser unit fails to function correctly, allowing your air conditioner to emit warm air.
