A contractor quoting a heat pump installation in Fayette County is not working around a climate that batters equipment constantly. 57 severe weather events were recorded in Fayette County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, which means the variables that drive sizing decisions are the ones that exist year-round: the thermal load of the home, duct layout, and the quality of the install itself. A system that underperforms here almost certainly does so because it was undersized or poorly commissioned, and that is what a contractor has to get right before anything else.
Ductwork laid down for a furnace and central air system carries air on a different set of assumptions than a heat pump runs on. Half the homes in Fayette County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). That vintage of construction means a contractor sizing and installing a heat pump is working out whether the existing duct layout and the home's electrical service will carry what the new system needs, before any equipment gets ordered. If the ducts restrict airflow or the panel needs an upgrade, that work comes first.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between inside and outside. The indoor air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or ceiling between them. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A disconnect box mounts near the outdoor unit and allows the contractor to cut power safely for service.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
