4 Reasons Your AC System in Myrtle Beach, SC, Won’t Stay On

As you use your air conditioner in Myrtle Beach, SC, pay attention to the length of each cycle, which should generally last between 10 and 15 minutes. Short cycles and uneven cooling may mean the AC system has a dirty filter, low refrigerant, a faulty thermostat or an excessively powerful blower.

Dirty Air Filter

Hopefully, it’s nothing more than a case of a dirty filter constricting airflow and causing the system to shut down prematurely rather than overheat. Homeowners should replace their filters once every three months for smooth air circulation.

Refrigerant Leak

AC systems can overheat and short-cycle from another source besides air blockage, and that’s a low refrigerant charge. Low refrigerant is usually the result of a leak in the lines, which is something that regular professional maintenance can detect early on and address.

Thermostat Trouble

Maybe nothing is wrong with the AC system itself, but the thermostat is telling it to shut down before it has reached your set point. This can happen if the thermostat incorrectly thinks the air conditioner has already reached it. It’s an issue of the sensors needing some calibration.

Incorrectly Sized AC System

There’s a popular misconception that the bigger the AC system, the better because it’ll cool the home faster. The reality is that air conditioners can be too large and powerful for a home.

An oversized AC system will cool your home very quickly but, at the same time, unevenly and with excessive wear and tear to the motor. If a mismatch is what’s causing the short cycles, your only recourse is to replace the air conditioner.
