Sizing a heat pump for Walker County starts with what the climate actually demands of it year-round, not with a model number that happens to be available. 79 severe weather events were recorded in Walker County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, and a contractor quotes around it rather than around an assumed moderate load. Refrigerant lines, electrical connections, and the compressor itself are specified for what this area runs against. A catalog install skips that work, and the system pays for it over time.
Ductwork laid down for a gas furnace or a window unit was not designed around the airflow a heat pump requires. Half the homes in Walker County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation in this county has to open and measure what is already in the walls and attic before the equipment choice means much, because duct sizing and electrical service that worked for the original system may not carry the new one. What the existing ductwork actually allows often sets both the scope and the cost of the job.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first, mounted on a concrete pad or wall bracket outside the house. It holds the compressor and the outdoor coil, and it is the part of the system that moves heat between the refrigerant and the outside air. The indoor air handler goes inside, usually in a closet, attic, or utility room, and it circulates conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or along the exterior to carry refrigerant back and forth. A thermostat or control panel goes on an interior wall and gives the homeowner a way to set temperatures and switch between heating and cooling modes.
The drawing shows how these pieces sit in a typical home, and a licensed contractor determines what the layout looks like for your specific house and setup.

Severe Weather Events in Walker County
Texas weather puts real demand on heating and cooling equipment, and Walker County has its own pattern of stress events that shape how hard a heat pump has to work over its lifetime. What gets installed here has to hold up to local conditions, which is why the weather record belongs alongside any honest conversation about equipment.
