A contractor quoting a heat pump installation in Lavaca County has to account for how the local climate actually behaves, not how bad seasons occasionally look on paper. 26 severe weather events were recorded in Lavaca County, Texas between 2015 and 2024. At that rate, severe weather is a periodic factor rather than a constant one, which means the sizing decisions and installation choices a contractor makes here rest primarily on the home's load requirements and the quality of the work itself. Ductwork fit, refrigerant charge, and equipment placement carry more weight on the final outcome than storm history does.

Ductwork laid in for older heating and cooling equipment was built to move air in a particular way, and a heat pump asks something different of it. Half the homes in Lavaca County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were designed for and what a heat pump needs is where a contractor's assessment is most consequential: not the unit on the pad, but what the existing duct system will actually carry at the volumes and pressures a heat pump runs. Electrical service in houses of that vintage follows the same logic, because the panel and the circuits going into a heat pump install were put in for something else. A contractor working a job here measures both before anything gets ordered.

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 pulls heat from outside air. The indoor air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. Together these two units are what a new heat pump installation puts in place.

A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or ceiling. 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 shows a typical layout, and a licensed contractor determines exactly what applies to your house.
