A heat pump sized for a milder place will run harder and recover more slowly every time conditions push it to its limits. 180 severe weather events were recorded in Licking County, Ohio between 2015 and 2024. At that rate, contractors working in this county treat equipment selection and refrigerant charge as site-specific calls, not specifications copied from a manual. A unit installed to the wrong capacity for this climate spends its working life compensating, and the compressor bears most of that load.
Ductwork laid in for older furnaces and window units was sized and routed for those systems, and when a contractor quotes a heat pump installation here, what that ductwork can actually move becomes the first thing to settle. Half the homes in Licking County, Ohio were built in 1980 or earlier (2020-2024 ACS 5-year). A heat pump's delivery requirements differ enough from what much of that older ductwork was built around that leaks, undersized runs, or poor return placement can undercut the new system before it runs a single cycle. The electrical service gets the same scrutiny: the panel that fed the old setup may not carry what the new unit draws. That assessment shapes the scope and the price before any equipment gets ordered.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the work of pulling heat from the outside air. Inside the house, the air handler mounts in a closet, attic, or mechanical room 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. A thermostat goes on an interior wall and serves as the control point for the whole system, telling both units when to run and at what level.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.
