Why Is My Ductless AC Not Cooling My Anthony, TX Home?

August 11, 2021

Ductless cooling systems are an energy-efficient and affordable way to cool your Anthony, TX home. Most of the time, they operate quietly and effectively to keep your home’s temperature and humidity comfortable. If your ductless AC suddenly stops cooling, here are a few of the possible reasons why.

Dirty Air Filter

A dirty air filter in the indoor unit interferes with the ductless AC system’s ability to push cooled air into your living space. It’s important to keep up with air filter maintenance. Ductless AC units may use disposable or reusable filters. If yours has reusable filters, follow the manufacturer’s timeline and instructions for cleaning them. If your ductless air conditioner has a disposable filter in each indoor unit, check it monthly, and replace it within three months.

Short Cycling

Short cycling is when an air conditioner turns on for a minute, turns off and turns on again almost immediately. According to the Department of Energy, air conditioners may short-cycle if they’re improperly sized or located in an area that’s drafty or near a heat source. Short cycling may also occur if an air conditioner’s capacitor or wiring is damaged.

Refrigerant Leak

A refrigerant leak in the conduit or outdoor unit could impair a ductless air conditioner’s ability to absorb heat from your home and transfer it to the outdoors. If too much of the refrigerant leaks out of the unit, the system’s safety limit switch will engage. This prevents the AC from turning on and requires a ductless AC repair.

Thermostat Malfunction

A malfunctioning thermostat may interfere with the ductless air conditioner’s functions. The thermostat’s sensor may have failed. The wiring between the thermostat and the indoor and outdoor units may be damaged. Improper thermostat placement may also affect the ductless system’s cooling.
