A contractor quoting a heat pump installation in Cumberland County starts with what the climate actually demands of the equipment, because sizing and refrigerant line decisions made without that picture produce a system that is underpowered before the first winter is out. 116 severe weather events were recorded in Cumberland County, Pennsylvania between 2015 and 2024. Severe weather at that rate is a standing condition, and a heat pump sized to catalog assumptions rather than local load will cycle harder, recover slower, and wear its compressor faster than the specs suggest. The install is where that math gets done right or wrong.
Ductwork laid down for a furnace and central air setup carries air at different pressures and volumes than a heat pump system expects, and whether what is already behind the walls and in the ceilings can handle that shift is the question a contractor has to answer before anything else is priced or ordered. Half the homes in Cumberland County, Pennsylvania were built in 1978 or earlier (2020-2024 ACS 5-year). That puts the duct runs and the electrical service at the center of most installation conversations here, not as a formality but as a real variable with real consequences for scope and schedule. A panel that was not sized for a heat pump's draw may need an upgrade. Ducts that cannot move enough air at the right velocity push a system to work harder than the equipment was rated for.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house, and it holds the compressor and the coil that pull heat from the outside air. Inside, the air handler sits in a utility space, basement, or closet and circulates conditioned air through the home. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two sides of the system communicate. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler for the coldest days.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

Licensing and Legal Requirements in Cumberland 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 Cumberland County
Heating and cooling equipment in Pennsylvania takes on real stress when outdoor conditions swing hard, and what that load looks like depends on where the equipment sits. A heat pump sized and installed for Cumberland County's weather history performs differently than one built around assumptions from somewhere else.
