A heat pump sized for mild conditions will struggle against what Muskingum County actually delivers. 154 severe weather events were recorded in Muskingum County, Ohio between 2015 and 2024. At that rate, severe weather is a standing feature of the climate, not an occasional interruption, and the load it places on a heat pump is something a contractor has to account for before settling on equipment specs. A unit undersized for the real demand cycles harder, recovers slowly on the coldest and hottest days, and wears its components faster. Contractors working here build that into both the equipment selection and the installation details from the start.
Ductwork designed for a furnace carries heat in bursts at high temperature. A heat pump moves conditioned air differently, at lower temperatures and higher volume, and ducts that were never built for that pattern often cannot deliver it without modification. Half the homes in Muskingum County, Ohio were built in 1972 or earlier (2020-2024 ACS 5-year). That vintage of construction means the ducts a contractor opens up were sized for equipment with a fundamentally different operating profile, and what they find inside determines whether the installation is a straightforward swap or a duct project with a heat pump attached. The electrical panel gets the same scrutiny: a service that was adequate for what was originally in the house draws a different judgment once a contractor measures what the new unit will actually pull.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, set on a pad beside the house, and it holds the compressor and the outdoor coil that do the main work of moving heat between the refrigerant and the outside air. Inside the home, the air handler sits in a utility space, basement, or closet and pushes conditioned air through the duct system.
A refrigerant line set runs between the two units through a small penetration in the wall, carrying refrigerant in both directions. The thermostat mounts on an interior wall and tells the system when to run, and an expansion valve inside the system controls how refrigerant moves between the coils.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.
