It can be quite disheartening when your AC blows warm air on a sweltering day. Perhaps you have noticed that the AC is still operating but is blowing warm air above the temperatures you have set. Since an AC should essentially give off cold air, you should contact your AC appliance professional immediately to fix the problem when it begins to blow warm air. This article looks at a few causes of this problem.
A Refrigerant Leak
The refrigerant facilitates heat exchange in the AC for cooling to take place. When there are low refrigerant levels, the AC may start blowing warm air instead of cool air. Since the refrigerant does not deplete with use, low levels might indicate a leak in the refrigerant lines or coils. This results in the AC losing the cooling power hence blowing warm air.
However, the refrigerant is poisonous and requires safety precautions when handling it. Therefore, you should hire an AC specialist since they understand how to refill the refrigerant safely. They will also repair the leaks to avoid future leakage.
Wrong Thermostat Setting
You should check your thermostat immediately if you notice warm air coming from your cooling unit. You may have incorrectly set the thermostat higher than the room's temperature and need to readjust it to solve the problem. Additionally, improper thermostat wiring may result in the thermostat giving erratic responses, thus causing your AC to blow warm air. Therefore, you should engage your home appliance service repair technician to rectify the wiring or replace the thermostat if it is defective.
Clogged Air Filters
Over time, debris may accumulate in the air filters, obstructing the flow of air into the AC. Since the evaporator coils require warm air so as to draw the heat from the air, restricted airflow renders them incapable of serving this function. This dysfunction results in the AC blowing warm air instead of cold. As such, it is important to have an AC professional service your AC regularly and clean or even replace the filters when they wear down.
Loss of Power of the Outdoor Unit
If you have a centralized AC, your outdoor unit houses the condenser responsible for cooling. When there is no current flowing through the exterior unit, there will be no cooling, and your cooling appliance will blow warm air. If the power cables are in good condition, the power loss could be caused by either a blown fuse or even a tripped circuit breaker. If the breaker keeps on tripping despite resetting it, you should hire an AC repair expert to ascertain the cause of power loss and repair it.
If your AC is blowing warm air, you should hire a home appliance service repair specialist to diagnose and fix the issues. They will also perform routine servicing and tune-ups to maintain the optimal functionality of your unit.
