HVAC ALL the WayWe concluded our recent discussion with “causing refrigerant to condense into a high-pressure liquid…” let’s find out what happens next.

Expansion Valve and Evaporator Coil

The high-pressure liquid refrigerant then travels to the indoor unit (air handler), where it passes through an expansion valve or metering device. The expansion valve regulates the flow of refrigerant into the evaporator coil, causing a drop in pressure. As the refrigerant expands, it absorbs heat from the indoor air, cooling it down. The now-cooled indoor air is then circulated back into the living space by a blower fan.

Sounds pretty fundamental, and it is. Next time we will check out the cycle and thermostat control. Our concluding discussion will review Straight Cool efficiency.

Check back soon as there is much to come…

Wishing everyone a safe and fantastic Fourth of July!
