Takes about a minute. No obligation.
A heat pump quoted from a catalog spec sheet, without adjusting for what the local climate actually demands, will be undersized or overworked before the first summer ends. 126 severe weather events were recorded in Hanover County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor sizing a new system has to treat it as a baseline input rather than an edge case. That means the equipment selected, the refrigerant line routing, and the placement of the outdoor unit all get decided around a climate that pushes systems hard with regularity.
Existing ductwork in a house built for a different generation of equipment is what shapes a heat pump installation here more than any choice of unit. Half the homes in Hanover County, Virginia were built in 1991 or earlier (2020-2024 ACS 5-year). That gap between when a house was framed and what a contractor is now asked to put in it means the duct system gets examined for whether it can move the air volume a heat pump requires, and the electrical service gets checked against what the new equipment will draw. The unit itself gets ordered after those answers come in.
What to Expect With a Heat Pump Installation
The outdoor unit sits on a pad or bracket outside the house and holds the compressor and the main coil. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. Together these two cabinets are the core of what a contractor puts in place.
A refrigerant line set runs between the two units, passing through a small penetration in the wall, and carries the working fluid back and forth. A thermostat goes on an interior wall where the homeowner sets temperatures, and a condensate drain line runs from the air handler to an appropriate discharge point.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your house.
