Sizing a heat pump for this county is not a question a contractor can answer from a spec sheet alone. 96 severe weather events were recorded in Huntingdon County, Pennsylvania between 2015 and 2024. At that rate of severe weather events, a system that is undersized or poorly matched to the local load will cycle harder, recover more slowly, and wear its components faster than the install specs would predict. A contractor quoting a job here has to account for what the climate actually demands before settling on equipment, not after.
Ductwork laid down for a furnace and window units was not engineered for the airflow a heat pump needs, and in a county where so much of the housing stock carries that original infrastructure, the duct system is what a contractor prices first. Half the homes in Huntingdon County, Pennsylvania were built in 1972 or earlier (2020-2024 ACS 5-year). That age puts most of the existing ductwork well outside the era when heat pump distribution requirements shaped how installers ran it. The electrical service in houses of that vintage is the second constraint: heat pumps draw on circuits that many of these panels were not wired to supply, and that gap shows up on the quote before the outdoor unit does.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, sitting on a concrete pad or wall bracket outside the house. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. Together these two units are what a heat pump installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run. Some installations also include a supplemental electric resistance element inside the air handler, which a contractor sizes to the house before the work begins.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits your home.

Licensing Rules for Huntingdon County, Pennsylvania
Pennsylvania names the trade in its own definition: installing central heating or air conditioning is a home improvement under the Act, whether or not the equipment is affixed — so an HVAC installation is work the registration requirement reaches.
A Pennsylvania registration displaces the local one: no political subdivision may require a home improvement contractor to register, license or pay a fee on top of it, though building permits and local code enforcement still apply.
Pennsylvania requires home improvement contractor registration rather than a licence: nobody may hold themselves out as a contractor, or perform any home improvement, without first registering with the Bureau of Consumer Protection.
Severe Weather Events in Huntingdon County
Weather puts a load on heating and cooling equipment, and that load is local. A heat pump sized and installed for Huntingdon County's conditions works against the actual climate here, not a regional average.
