Why Won’t My Ductless AC System Cool My House?

Your ductless air conditioner in Star City, AR, is a reliable feature of your home. But when it suddenly stops working, it won’t take you long to feel hot and uncomfortable. There are multiple reasons a ductless AC system can stop cooling, and these signs can help you identify the possible causes. Learn more about some common causes of ductless AC failure today.

Ductless AC Compressor Failure

The compressor is a vital part of your ductless AC system. When it fails, your mini-split can’t effectively cool your home. The condenser pressurizes your system’s refrigerant, allowing it to cool your home. Without a functioning condenser unit, your ductless AC system won’t be able to cool your home.

Warning signs of a damaged or broken compressor include:

• Strange noises.
• Increased energy consumption.
• Frequent cycling.
• Blowing warm air.

Refrigerant Leak

Refrigerant makes cooling possible. If your ductless AC system has a leak, the mini-split won’t be able to effectively cool and reach your desired temperature. Common signs of a refrigerant leak include reduced performance, a sweet smell coming from your ductless air conditioner and high-pitched hissing noises.

Frozen Evaporator Coil

As ironic as it sounds, a frozen evaporator coil can prevent your ductless AC system from cooling your home. When ice builds up on the evaporator coil, it blocks airflow while also negatively impacting the heat transfer process.

A frozen evaporator coil is usually caused by dirty air filters, low refrigerant levels or blocked air vents. Though it may seem easy to fix, it’s best to leave it to one of our professional HVAC service techs.

A broken HVAC system during the summer isn’t only inconvenient but can also be unsafe. If you need a AC repair for your mini-split in Star City, AR, contact Pine Bluff Heating & Air today.
