HVAC

 

Electrical wiring of HVAC is rather straight forward, BUT dangerous.

Never work on HVAC unless you are absolutely, positively, sure high voltage circuits are dead

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 compressor’s coils and up and then away from the unit.
