A heat pump installation in Harrison County has to be sized for what this climate actually delivers, not for what a catalog assumes. 163 severe weather events were recorded in Harrison County, Texas between 2015 and 2024. At that rate, severe weather is a regular part of the operating environment every system here runs against, and a contractor who treats it as a rare variable will undersize both the equipment and the installation's structural margins. Refrigerant line routing, unit placement, and electrical specifications are all local decisions here, not defaults.
Ductwork designed for older heating and cooling equipment was laid out for different static pressure and air volume than a heat pump requires, and in Harrison County that gap is common. Half the homes in Harrison County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here will open supply and return runs, measure whether the existing trunk lines move enough air, and price from what they find. Houses where the ductwork holds up get a cleaner install. Houses where it does not need remediation that only shows up once someone gets into the system.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the core work of moving heat between inside and out. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home. Together these two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two and carrying the working fluid back and forth. A thermostat goes on an interior wall where the homeowner controls the system, and a condensate drain line runs from the air handler to carry away any moisture the indoor coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your specific home.

Severe Weather Events in Harrison County
Weather puts a measurable load on heating and cooling equipment, and that load is shaped by what actually happens here, not by averages drawn from somewhere else. A heat pump sized and installed for Harrison County's conditions works against the climate this county actually records.
