A/C Question

Specific Inspection Topics Inspecting HVAC Systems

Copied from another website. Is it true?

"Your central air conditioner has a heater that vaporizes the refrigerant. If you leave power to the air conditioner on, the heater runs all winter. Not only does that unnecessary effort waste energy and money, it wears out the heater faster.

Some air conditioner compressors have a nearby shutoff switch. If not, you must shut it off at the main electrical panel."

Yes some air conditioning units have a crankcase heater to vaporize any liquid refrigerant that migrates to the compressor during the off cycle.

The power must be on to the air conditioner for at least a 24 hour period before turning it on.
