A heat pump installation in Portsmouth starts with what the site actually demands, and a contractor has to nail the sizing and duct work before any equipment choice makes sense. 35 severe weather events were recorded in Portsmouth city, Virginia between 2015 and 2024. At that rate, severe weather is an occasional event rather than a steady operating condition, which means a unit that struggles here is far more likely carrying the weight of a poor original install or a mismatch in capacity than it is of storm load. The contractor's first job is to establish what the house truly needs, measured against its envelope and layout, and get the equipment matched to that.
Ductwork laid down for a different generation of equipment carries assumptions about airflow that a heat pump does not share. Half the homes in Portsmouth city, Virginia were built in 1967 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here has to assess whether those existing ducts can handle the system's lower supply-air temperatures and higher airflow volumes without creating pressure problems or dead zones. If the ductwork falls short, the electrical service gets priced second. The box on the wall is the straightforward part of that quote.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners see first. It sits on a pad outside the house and holds the compressor and the outdoor coil. Inside, the air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. These two units are the core of what a contractor places.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the system.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the conditions of your house.
