Why Your AC Is Shutting Off on Its Own

Air conditioners make even the hottest days of the year bearable. They also help keep the air you breathe indoors clean by removing excess humidity, which can attract airborne pollutants. Be aware the likelihood of system failure increases when your AC is constantly running during the summer. 

In this post, Dittmer Air and Heat discusses what causes an AC to shut off on its own and what you can do to fix it.

Burnt Motors

The motors are in charge of driving the compressor and fans. If they overheat, they will burn out and the air conditioner will shut down. You may have a damaged motor if you smell something burning coming from your vents.

Compressor Issues 

The compressor is an essential component of your HVAC system. It circulates the refrigerant through your equipment, allowing the unit to provide cool air to your living space. When this piece fails, your air conditioner also fails. For repairs or replacement, you’ll need to contact a qualified technician.

Dirty Evaporator Coils 

The condenser coils are located outside the house. They will work harder to meet your cooling needs when they are obstructed by dirt and debris.

Frozen Evaporator Coils

Ice forms on the coils when they are dirty or there is insufficient airflow. Your AC may shut off on its own due to frozen evaporator coils. To melt the ice on the coils, the entire system must work harder, putting strain on the equipment and causing the unit to overheat.

Poorly-Sized Equipment 

An experienced technician will measure your space before recommending and installing an air conditioner. HVAC systems remove a specific amount of heat from a particular area size. If your air conditioner is too big, it will short-cycle or shut down sooner. That said, units that are appropriately sized for the room operate more efficiently and consume less energy.
