How It Works

T he basic concept is that as a gas moves from an area of high pressure to an area of low pressure, it gets colder high pressure is high temperature, and low pressure is low temperature. Your AC compressor circulates refrigerant at high pressure through a tiny hole into a larger area, thereby dropping the pressure and temperature rapidly.

Fans then blow this cold air out into your house. Since warmer air holds more moisture than cooler air your air conditioner will also act as a dehumidifier and produce water. This water collects in a drain pan and the excess water is drained out of the home.

Working Properly

A  proplerly working air conditioner will cool the temperature of the air between 16-22 degrees.

A properly sized, and properly working unit should cool the air 3-5 degrees per hour of operation. If a home is ducted properly and insulated sufficiently every room in the home should be within 2 degrees of each other.
Does your air conditioner have any of these symptoms?

A/C Maintenance

  • Replace or clean (washable) air filter a minimum of every 3 Months
  • Condensing coil should be cleaned once a year
  • Inspect drain line periodically for proper drainage and connect a shop vac at end of drain line to suck out built up debris and obstructions
  • Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort

Air Conditioner Red Flags

  • Running continuously but not cooling the home
  • Wide range of temperatures from room to room
  • Water not draining out of the primary drain line
  • Warm suction refrigerant line (thicker of the two copper refrigerant lines on a split a/c system)
  • A/C compressor or fan when running is noisy
