A contractor quoting a heat pump replacement in Henry County works through site conditions and the state of the existing equipment before weather load enters the calculation. 66 severe weather events were recorded in Henry County, Kentucky between 2015 and 2024. At that rate, severe weather is a real but periodic pressure on equipment here, not a constant one. What drives sizing decisions is the specific house: duct layout, insulation, and how the previous system was installed and maintained. A unit that failed early almost certainly failed for those reasons, and a contractor scoping the job will check them before attributing anything to storm history.
Ductwork laid down for a furnace was sized for the high-velocity, high-temperature air a gas system moves. Heat pumps move more air at lower temperatures, and ducts that worked fine for decades can restrict airflow enough to undermine a new unit's efficiency before it runs a full season. Half the homes in Henry County, Kentucky were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here measures duct capacity and checks the electrical service, because those two things determine what the job actually costs and how the finished system performs.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first: a metal cabinet set on a pad outside the house that holds the compressor and one set of coils. Inside, an air handler mounts in a closet, utility room, or attic and moves conditioned air through the home. Together these two units do the work of both a furnace and a central air conditioner.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installs also include an auxiliary heat strip inside the air handler to cover the coldest stretches of the year.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific house.

Severe Weather Events in Henry County
Weather puts a measurable load on heating and cooling equipment, and that load varies by location. A heat pump sized and installed for what Henry County actually sees will hold up better than one spec'd to a national average.
