A contractor quoting a heat pump installation in Henry County has to account for what the local climate actually asks of equipment, and that means sizing to real conditions rather than a regional average. 92 severe weather events were recorded in Henry County, Ohio between 2015 and 2024. At roughly the national midpoint for severe weather activity, the county sees enough to matter but not enough to dominate every sizing decision. What that means in practice is that a poorly sized or sloppily installed system will show strain that looks weather-driven but traces back to the install itself, and a contractor who knows this area will price and spec accordingly.
Ductwork laid down for a furnace was sized and routed to push hot air, and a heat pump running in heating mode moves a larger volume of cooler air to reach the same result. Half the homes in Henry County, Ohio were built in 1964 or earlier (2020-2024 ACS 5-year). In a house that old, the existing duct runs, their cross-sections, and the returns all reflect what the original system needed, not what a heat pump needs. A contractor installing a heat pump here measures and pressure-tests before anything else, because a mismatch in the ductwork shows up as uneven temperatures and higher electric bills once the system is running.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners see first. It sits on a concrete pad or wall bracket outside the house and holds the compressor and the outdoor coil, which together do the heavy lifting of moving heat between the refrigerant and the outside air. The indoor air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. The thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. Some installations also include a backup heat strip inside the air handler for use on the coldest days.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house based on its size, configuration, and existing infrastructure.
