Sizing a heat pump for Hartley County starts with the climate, because the climate here is not a mild background variable. 216 severe weather events were recorded in Hartley County, Texas between 2015 and 2024. At that rate, every system installed in this county has been running against sustained environmental pressure, and a contractor who ignores that when selecting equipment capacity, refrigerant line routing, or mounting location will produce an install that underperforms before the first service interval. A heat pump sized for a gentler operating environment will cycle harder, recover slower, and strain its compressor under loads the catalog spec was never built for here.

Ductwork laid down for a furnace-and-window-unit setup was not designed around the airflow a heat pump needs, and in much of Hartley County's housing stock that mismatch is what a contractor spends the most time working out. Half the homes in Hartley County, Texas were built in 1979 or earlier (2020-2024 ACS 5-year). A house that old was almost certainly ducted for something else, and what a contractor finds behind the registers determines whether the existing runs can carry the new system or need to be reworked before the equipment goes in. The electrical panel follows the same logic: service sized for a different era of appliances gets checked against what the new unit draws.
What a Heat Pump Installation Covers

The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a closet, attic, or utility space and pushes conditioned air through the home. These two units are the core of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that links the two. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. Both the line set and the thermostat are part of what a new installation includes.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly what applies to your house.

Severe Weather Events in Hartley County
Hartley County weather puts real demands on heating and cooling equipment over its lifetime. How hard a heat pump works, and how long it lasts, is shaped by local conditions, which is why that record belongs on a page about installation.
