A contractor quoting a heat pump install in Castro County has to size for what this area actually runs against, not for a mild baseline. 137 severe weather events were recorded in Castro County, Texas between 2015 and 2024. At that rate, severe weather is a standing operating condition rather than a rare event, which means a unit sized for average demand will spend a meaningful part of its life working against conditions it was not built for. A contractor who accounts for that load during installation chooses equipment and placement that holds up across real seasons here, and a homeowner who gets that quote right the first time avoids a system that underperforms from the day it goes in.
Ductwork put in for one era of equipment does not automatically carry the next. Half the homes in Castro County, Texas were built in 1966 or earlier (2020-2024 ACS 5-year). A heat pump draws on the existing duct layout and the electrical service already in the house, and in stock this old, both were sized for something different from what a licensed contractor installs now. That gap is where the real variation in scope comes from. Some houses have been updated over the years and the infrastructure holds; others have not, and a contractor has to open walls or panels before a quote means anything.
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 outside air. The indoor air handler mounts in a utility space, attic, or closet and moves conditioned air through the home. Together these two cabinets are the core of what gets installed.
A refrigerant line set runs between the two units, carrying the fluid that transfers heat from one side to the other. A thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. The disconnect box and condensate drain line round out what a contractor places during the job.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific home.
