A contractor quoting a heat pump install in Armstrong County has to get the sizing right before anything else. 162 severe weather events were recorded in Armstrong County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition in this area, which means a unit that is even slightly undersized will run at or near its limit far more often than a loose estimate would predict. The brand on the cabinet matters less than whether the capacity fits what the climate actually asks of it. A correctly sized unit installed with that load in mind gives the compressor and refrigerant circuit a reasonable chance of running as expected; a unit that is too small starts behind.
Ductwork and electrical service are what decide how a heat pump installation goes, and in Armstrong County, the electrical side is the part that stops a job before it starts. Half the homes in Armstrong County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). A home built in that era carried a panel sized for the loads of that era, and a heat pump draws more than what those panels were designed to handle. A contractor has to assess the existing service before a unit gets quoted, because the panel upgrade, if one is needed, changes the scope of the whole 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. The indoor air handler mounts inside, most often in a utility closet, attic, or basement, and moves conditioned air through the home. Together these two cabinets are the core of what a contractor installs.
A refrigerant line set runs between the two units, carrying the refrigerant that lets the system do its work, and a condensate drain line carries moisture away from the air handler. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what goes where based on the specifics of your house.

Severe Weather Events in Armstrong County
Weather conditions in this part of Texas drive how hard heating and cooling equipment has to work and how often. A heat pump sized and installed for local conditions handles that load differently than one built to a generic spec.
