Sizing a heat pump for a Caswell County home starts with what the climate actually asks of that equipment. 151 severe weather events were recorded in Caswell County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing condition, and a contractor working an install here has to build that load into the sizing calculation from the start. A unit sized for a calmer environment will run harder, cycle more, and reach its limits sooner. The install specifications that follow from honest local sizing are different from what a catalog chart alone would produce.
Ductwork laid down for a furnace or a window unit was sized and routed for a different kind of system. Half the homes in Caswell County, North Carolina were built in 1981 or earlier (2020-2024 ACS 5-year). A heat pump moves a larger volume of air at lower temperature differentials, and ducts built for anything else often cannot carry that load without modifications a contractor has to measure before the equipment gets ordered. The electrical service runs into the same question: what the panel was built to handle and what a heat pump actually draws are two numbers a contractor has to reconcile before a quote means anything.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad beside the house. Inside, the air handler sits in a closet, basement, or attic and moves conditioned air through the home. Together these two units are the core of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two units do their job. A thermostat goes on an interior wall where it can read the living space and give the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
