Sizing a heat pump for a Washington County home starts with what the structure asks of the system, not with a tally of rough seasons. 36 severe weather events were recorded in Washington County, Texas between 2015 and 2024. At that rate, severe weather is a real but infrequent variable, and a contractor quoting an installation here will spend more time on load calculations, equipment placement, and duct design than on any assumption that storm exposure is the governing factor. The installation decisions that shape a system's long-term performance in this county come down to how well the unit is matched to the structure and how cleanly the refrigerant lines and air distribution are set up.
Ductwork laid down for a central air system built around older equipment carries specific dimensions, joint types, and return configurations that a heat pump's airflow demands do not always match. Half the homes in Washington County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump install here will pull registers, measure static pressure, and assess whether existing runs can move the volume the new system requires before any equipment gets ordered. If the ducts fall short, the electrical panel is the next question. A heat pump draws differently than what most of this housing stock was wired for, and that calculation happens before the unit is ever placed.
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 system's main work. Inside, an air handler mounts in a utility space, closet, or attic and moves 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 mounts on an interior wall and gives the homeowner control over the system. Some installations also include a disconnect box near the outdoor unit, which sits between the unit and the electrical supply.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece positions within it.

Severe Weather Events in Washington County
Weather extremes put direct demands on heating and cooling equipment: the harder a system has to work, the more its sizing, installation quality, and component choices matter. What happens outside in Washington County shapes what a heat pump needs to do year-round.
