Air Conditioning 101

Before talking about potential problems and our repair services, it might be helpful to provide a brief explanation of how your central AC unit works, without getting too far into the technical weeds.

Basically, the air handler fan of your unit draws in air from the interior of your home that is blown across the evaporator coil that sits in the interior portion of your AC unit. Heat is absorbed into the refrigerant that’s in the coil, and the cooled air is distributed throughout your home.

Meanwhile, the refrigerant and heat are pumped to the condenser – the part of the unit that sits outside the house. The condenser unit cools the refrigerant while blowing the heat into the outside air. The cooled refrigerant is pumped back into your house, and the cycle repeats itself.

Sources of Trouble

When everything is operating as it should, your house remains cool and comfortable, but there are any number of things that can go wrong including:

• A leak in the refrigerant
• Compressor failure
• Power failure
• A frozen evaporator coil

Signs of Trouble

With those sources of trouble in mind, here are some of the signs indicating you need to call the AC repair experts at Sullivan Super Service:

• Outside, strange noises from the compressor unit
• Compressor is not running
• Inside, warm air blowing out of the registers
• High humidity, even when the unit’s running
• AC system not turning on at all
