How does a compressor work in HVAC?

HVAC 101: Your Compressor As we noted before, your compressor produces high-pressure, high-temperature gas, which flows through the outdoor coil, releasing heat. It does this by squeezing (compressing) the refrigerant into a smaller and smaller space, producing a gas under extremely high pressure.

How does AC unit work with furnace?

How central heating works. During warm seasons your heating system works with your central air conditioning.
