Sizing a heat pump for a house in Guadalupe County starts with what the climate has actually been asking of equipment here. 104 severe weather events were recorded in Guadalupe County, Texas between 2015 and 2024. That puts this area somewhere between a place where severe weather is rare enough to ignore and one where it drives every specification. A contractor still has to work through the structure of the house, the duct layout, and the exposure of the installation site before they can quote a system that will carry the load without being oversized for the stretches of ordinary weather that make up most of the year.
Ductwork and electrical service are what a contractor prices before anything else on a heat pump job, and in Guadalupe County the electrical is where the real question sits. Half the homes in Guadalupe County, Texas were built in 2003 or earlier (2020-2024 ACS 5-year). A house built then was wired for whatever the builder put in at the time, and heat pumps draw differently than what that original service was sized for. If the panel needs an upgrade, that work goes into the quote before the equipment does.
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, usually in a utility closet, attic, or basement, and moves conditioned air through the home. Together these two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing that passes through the wall. A condensate drain line also connects to the air handler to carry away moisture, and a thermostat mounts on an interior wall to give the homeowner control over the whole system.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece applies to your house.

Severe Weather Events in Guadalupe County
What the climate throws at a building shapes how hard a heat pump has to work and how long it holds up doing it. That load profile is local, and equipment sized and installed for Guadalupe County conditions is a different conversation than one sized anywhere else.
