Step 1 of 3: Equipment

A heat pump sized and installed for this county's actual demand will carry that load without being overbuilt or undersized for it, and a contractor working here has to get those numbers right before any equipment gets ordered. 66 severe weather events were recorded in Dawson County, Texas between 2015 and 2024. At that rate, severe weather touches equipment here now and then, but age, installation quality, and how well the refrigerant charge was set on day one are what determine whether a system is still running well years later. A contractor who quotes a heat pump job in Dawson County is specifying around real conditions, not padding for a climate that hammers equipment week after week.

Ductwork laid in for a furnace or a window-unit era moves air on a different set of assumptions than a heat pump requires, and in Dawson County a substantial share of the housing stock was built under exactly those assumptions. Half the homes in Dawson County, Texas were built in 1963 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here checks whether the existing duct layout can handle the lower supply-air temperatures and the longer run cycles the system will use. If the ducts cannot, that work comes before the equipment question. The electrical panel gets the same look, since older service was sized for what the house needed then.

What to Know About a Heat Pump Before Installation

The outdoor unit sits on a pad outside the house and holds the compressor and coil that do the primary work of moving heat between inside and outside. The indoor air handler mounts in a closet, attic, or mechanical room and circulates conditioned air through the home. These two units are what a contractor places and connects during the job.

A refrigerant line set runs between the outdoor unit and the air handler, carrying the fluid that links both sides of the system. A thermostat on an interior wall gives the homeowner control over the whole setup, and a condensate drain line carries moisture away from the indoor unit to a suitable discharge point.

The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your house.
