Sizing a heat pump for Sherman County starts with an honest look at what the system will actually face here. 171 severe weather events were recorded in Sherman County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of this climate, and a contractor who ignores it when calculating load and selecting equipment is setting a system up to run beyond its design range on a regular basis. A unit quoted from a catalog without that adjustment may keep a house comfortable for a season or two, then spend the rest of its life short-cycling or overworking its compressor to cover the gap the installer left.
Ductwork laid down for older heating equipment was designed around different airflow demands than a heat pump puts on it. Half the homes in Sherman County, Texas were built in 1966 or earlier (2020-2024 ACS 5-year). That gap between the original construction and what a heat pump requires is where an installation job gets complicated or stays straightforward. A contractor assessing a Sherman County home has to open up and measure what is there before any equipment decision is final, because the ducts determine whether the new system will deliver what it is rated to deliver.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad outside the house and holds the compressor and coil that do the core work of the system. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the air handler to a floor drain or outside, carrying away moisture the system pulls from the air.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned.
