A contractor quoting a heat pump installation in Randall County starts from what this climate actually asks of the equipment, not from a standard sizing table. 390 severe weather events were recorded in Randall County, Texas between 2015 and 2024. At that rate, severe weather is a routine operating condition, and a system sized without accounting for it will be working against the local load from the first season. Refrigerant line placement, unit positioning, and equipment ratings all become local decisions shaped by what the weather here puts a system through year after year.

Existing ductwork in a house this age was sized and routed for a different system, and whether it can move the air a heat pump requires is what a contractor has to settle before anything else gets priced. Half the homes in Randall County, Texas were built in 1986 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and when heat pumps became the standard choice is long enough that the original duct layout reflects assumptions the new equipment does not share. A panel that was adequate then may not carry what the new unit draws either. The electrical and the ductwork together are what the job turns on, and both have to be looked at before the equipment selection matters.
What a Heat Pump Installation Puts in Your Home

The outdoor unit sits on a pad beside the house and holds the compressor and the coil that pull heat from outside air. The indoor air handler mounts in a closet, attic, or utility room and pushes conditioned air through the house. These two units are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the refrigerant that moves between them. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly what the configuration looks like in your house.
