A contractor quoting a heat pump installation in Lampasas County has to size and spec for a climate that does push the equipment, but not relentlessly. 46 severe weather events were recorded in Lampasas County, Texas between 2015 and 2024. At that rate, severe weather is an event rather than a standing condition, which means the dominant variables in how a system performs over its life are how well it was sized for the house and how cleanly it was installed. A unit that degrades here is pointing at the work that set it up, not at the weather it has run through.
Ductwork laid down for older heating and cooling systems was designed around different static pressure and airflow assumptions than a heat pump requires. Half the homes in Lampasas County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation in a house from that period of the stock has to assess whether the existing duct layout and the electrical service will carry what a modern unit draws, before any equipment choice gets priced. A panel that met code for the original system and ductwork that was routed for it can both fall short of what a heat pump needs, and that assessment shapes the scope of the job.
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 exchange heat with the outside air. Inside, an air handler mounts in a closet, attic, or utility space and pushes conditioned air through the home. These two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall where it reads the living space and signals the system to run. A disconnect box mounts near the outdoor unit to allow the equipment to be safely shut off for service.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your house.
