Sizing a heat pump for Moore County is not a step a contractor can treat as a formality. 228 severe weather events were recorded in Moore County, Texas between 2015 and 2024. At that rate, severe weather is a routine operating condition, and a system sized without accounting for it will spend its life running at or past its limits. A contractor who quotes by catalog spec alone, without factoring in what the local climate actually demands, leaves the homeowner with equipment that starts wearing the day it is installed. The right install begins with an honest load calculation specific to this area.
Ductwork designed for a system from a prior generation of HVAC equipment carries different airflow expectations than a heat pump requires. Half the homes in Moore County, Texas were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump in stock of that vintage has to assess whether existing duct runs, their sizing, and their routing will move air the way the new system needs, before the equipment selection matters at all. If the ductwork cannot carry it, that work gets priced and done first. The electrical service gets the same look, since the draw of a heat pump differs from what older panels were wired to handle.
What Goes Into a Heat Pump Installation
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil, the two components that do the heaviest work in the system. Inside, the air handler mounts in a closet, attic, or utility space and moves conditioned air through the home. Together these two units are what a contractor is placing, connecting, and commissioning.
A refrigerant line set runs between the outdoor and indoor units, carrying the working fluid that links them. The thermostat goes on an interior wall where it reads the living space and tells the system when to run. A contractor also sets the condensate drain line at the air handler to carry moisture out of the house.
The drawing shows a representative layout, and a licensed contractor determines what fits the specific conditions of your house.
