Sizing a heat pump in Coke County starts with what the site and the existing setup actually demand, not with assumptions carried in from a busier climate. 66 severe weather events were recorded in Coke County, Texas between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means the decisions that shape an installation well are the ones contractors have always made in quieter counties: load calculations tied to the specific structure, refrigerant line routing that suits the property, and equipment spec matched to actual heating and cooling demand rather than worst-case weather. A system installed carelessly here will fail on its own terms.
Ductwork laid down for a furnace and window units was designed around a different kind of air movement than a heat pump requires, and in housing of this vintage that gap shows up early in the quote. Half the homes in Coke County, Texas were built in 1974 or earlier (2020-2024 ACS 5-year). That means a contractor arriving to install a heat pump is evaluating the existing duct layout and its condition before the new unit is ever selected, because what is already in the walls and ceiling decides whether the system will move air the way it is supposed to. The electrical panel gets the same look, since the loads a heat pump draws were not part of the original design. What a contractor quotes depends heavily on what those two things turn out to be.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or wall bracket outside the house, and it holds the compressor and the condenser coil. Inside, the air handler sits in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units do the physical work of the system.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two sides communicate. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. An expansion valve, tucked inside the air handler, controls how the refrigerant flows between the two units.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your house.

Severe Weather Events in Coke County
Weather extremes put a direct load on heating and cooling equipment, and that load shapes what a heat pump needs to handle over its working life. Sizing and installation decisions in Coke County are grounded in local conditions, not regional averages.
