- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream

Do heat pumps work well in cold winters?

What does a heat pump installation involve?
A single-zone ductless system is generally the simplest install; multi-zone and ducted whole-home systems take more time depending on the number of zones and line-set length. You get a firm written price before any work starts — call for a quote.
