High Voltage Air Conditioning (HVAC) - Basics Summary: HVAC is not rocket science but information about HVAC is scattered all over the Internet. In this document, I try to define in a concise way. Background: There are 4 different aspects of HVAC: - Components. - High voltage electrical wiring. - Control wiring and circuit boards. - Refrigerant. Components: A HVAC system that is either just air conditioning or a heat pump consists of: - A wall mounted thermostat. - An air handler, which is inside the house either in a closet, utility room or in the attic. The air handler contains coils that either absorb or give off heat. Heated or cooled air is then circulated through the duct system via an air handler blower motor. - Compressor unit. The compressor is located outside and again contains coils, a compressor motor and a fan that moves outside air through the compressors coils and up and then away from the unit. HVAC with a furnace has a natural gas or oil-fired burner as part of the air handler.
