Sizing a heat pump for Putnam County starts with what the system will actually run against. 197 severe weather events were recorded in Putnam County, West Virginia between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, and a contractor who ignores it when selecting equipment and planning an install is setting the homeowner up for a system that works on paper but underperforms in place. Refrigerant line placement, unit mounting, and equipment ratings all answer to local conditions here in ways a standard catalog spec does not account for.
Ductwork sized and routed for older heating equipment is what a contractor runs into across a large share of Putnam County's housing stock. Half the homes in Putnam County, West Virginia were built in 1989 or earlier (2020-2024 ACS 5-year). Systems from that period were built around fuel sources and airflow volumes that a heat pump does not replicate, which means the existing duct layout may move air in ways that work against the new unit's efficiency from day one. An electrician also has to look at the panel before anything gets quoted, because the service coming into houses of that vintage was not provisioned for the draw a heat pump puts on it. The duct run is where the install either holds to its original scope or grows.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house, and it holds the compressor and the outdoor coil that do the system's core work. Inside, the air handler sits in a mechanical closet, basement, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, typically along an exterior wall, carrying the working fluid back and forth. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A disconnect box mounts near the outdoor unit and lets a contractor cut power to it safely.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is placed and configured for your specific house.
