A contractor sizing a heat pump in Lamar County is solving a local problem, not pulling a figure from a chart. 70 severe weather events were recorded in Lamar County, Alabama between 2015 and 2024. At that rate, severe weather here is an occasional fact of life, not a standing pressure on every system. What that means for an install is that the work lives or dies on proper load calculation and the quality of the setup itself. A poorly sized unit or a rushed refrigerant charge will fail here the same as anywhere, and the weather record does not explain it.
Ductwork sized and routed for an older system carries real consequences when a heat pump goes in. Half the homes in Lamar County, Alabama were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor pricing a new heat pump here checks what the existing duct network can actually move and whether the electrical service will carry the load, because both were built to different specs than a heat pump requires. Where the ducts fall short, the installation scope grows before the unit is ever touched.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between inside and outside. Inside, the air handler mounts in a closet, attic, or utility room and pushes conditioned air through the home.
A refrigerant line set connects the two units, running through the wall to carry refrigerant back and forth between them. A thermostat mounts on an interior wall and gives the homeowner control over the whole system, telling the heat pump when to run and what temperature to hold.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits into your particular house.

Severe Weather Events in Lamar County
Weather puts a load on heating and cooling equipment, and that load varies by location. A heat pump sized and installed for what Lamar County actually experiences will run more reliably than one spec'd to a generic standard.
