A contractor quoting a heat pump installation in Galveston County has to treat severe weather as a built-in operating condition, not an edge case the system might occasionally face. 94 severe weather events were recorded in Galveston County, Texas between 2015 and 2024. At that rate, the climate here is part of what determines how a unit gets sized and how the refrigerant lines, electrical connections, and mounting hardware get specified for the site. A system installed to catalog defaults for a mild area will be undersized for what this county actually asks of it.
Ductwork laid down for a central system running on different airflow assumptions does not automatically suit a heat pump. Half the homes in Galveston County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). That age of construction means the ducts a contractor walks into were designed around equipment with different static pressure and airflow requirements than what a modern heat pump needs, and the electrical service wired at the same time may not match what a new unit draws. A contractor installing a heat pump here sizes the duct system alongside the equipment, not after it.
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 exchanges heat with the outside air. Inside, an air handler mounts in a utility space, closet, or attic 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, and a condensate drain line carries moisture away from the indoor coil. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

Severe Weather Events in Galveston County
Galveston County's climate puts real demands on heating and cooling equipment, and those demands are shaped by what the weather actually does here year after year. A heat pump sized and installed for local conditions handles that workload differently than one specified for somewhere else.
