A contractor quoting a heat pump installation in Kendall County has to work out what the local climate actually demands of a system before any equipment gets specified. 55 severe weather events were recorded in Kendall County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a standing operating condition, which means the case for a particular system size or refrigerant line configuration comes down to the thermal load of the house, the quality of the ductwork, and how well the outdoor unit is sited. Weather is a real input, but it is not the dominant one. Contractors who get the load calculation wrong in either direction leave the homeowner with a system that short-cycles or runs constantly, and no subsequent tuning fixes a bad install.
Ductwork and electrical service in Kendall County houses were laid down recently enough that a contractor sizing a heat pump installation here is working with infrastructure built for modern load expectations. Half the homes in Kendall County, Texas were built in 2002 or earlier (2020-2024 ACS 5-year). That matters because it narrows what a contractor has to resolve before quoting: the panel and the ducts in a house of this vintage are unlikely to be the constraint, so the work turns on matching the right unit to the house's actual layout and exposure rather than on correcting what is behind the walls.
What a Heat Pump Installation Covers
The outdoor unit sits on a concrete pad or wall bracket outside the house and holds the compressor and the coil that exchanges heat with the outside air. The indoor air handler mounts in a utility space, closet, or attic and circulates conditioned air through the home. Together these two units are what a contractor places and connects during an installation.
A refrigerant line set runs between the two units, carrying the refrigerant that makes the exchange possible, and this line gets routed through the wall or ceiling to bridge the indoor and outdoor sides. A thermostat on an interior wall ties the whole system together, giving the homeowner control over when and how the system runs.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly how each one applies to your house.

Severe Weather Events in Kendall County
The load a heat pump carries is shaped by what the climate actually does, not just its averages. Storm activity drives temperature swings and humidity spikes that determine how hard the equipment has to work, which makes local weather history a real factor in sizing and installation decisions.
