If your air conditioner stops cooling, chances are you’ll soon have an HVAC technician at your home diagnosing the problem. We’ve put together a guide to help you navigate through the repair process with a better understanding of a few terms you’ll likely hear.
Condenser Coil – Located outside and pushes heat out. This component holds refrigerant.
Evaporator Coil – Located indoors and absorbs heat. Also holds refrigerant.
Two Stage Cooling – An automatically adjusting component. It can operate at two speeds: high and low. Which speed it runs on is based upon how hot it is outside.
Zones or Zoning – Created to increase comfort through the home and to help eliminate extreme hot or extreme cold rooms. Zones are controlled from your thermostat. Each zone controls a set of vents. Within the vents are dampers which change the direction of air flow.
Duct Work – Tubes that carry conditioned air to the rooms within a space.
Variable Speed – This refers the motor on the indoor unit that adjusts based upon what the thermostat is calling for and what the home requires.
Refrigerant – This is the gas that cools the air within your home through the coils. There are two main types: R-22, which is being phased out by the EPA and R-410A, which is the more environmentally friends replacement of R-22.
Compressor – The heart of your air conditioner. It converts refrigerant from a low pressure gas to a high pressure gas.
Float Switch – This is a sensor usually attached to the drain pan on your furnace. If water reaches a certain height, the sensor will shut the system off automatically so that you don’t end up with water damage within your home.Condensate Drain – Your evaporator coil creates condensation. This water leaves your home via the condensate drain, which leads all the way outside. These can clog from time to time and need to be cleared.
