A heat pump install in Limestone County is a local engineering decision, not a catalog pick. 228 severe weather events were recorded in Limestone County, Alabama between 2015 and 2024. At that rate, severe weather is part of what every system here runs against across its life, which means the sizing conversation a contractor has before any equipment is ordered needs to account for that operating reality. A unit sized for mild, stable conditions leaves a homeowner short when conditions are anything but. Contractors working this county build that load into the equipment selection from the start.
Ductwork laid down for a gas furnace or a window-unit setup was not designed around the airflow a heat pump system needs, and whether it can carry one is the first real question a contractor has to answer on most jobs here. Half the homes in Limestone County, Alabama were built in 1998 or earlier (2020-2024 ACS 5-year). A house that old runs a real chance of having supply runs, return capacity, or both that fall short of what a new heat pump draws on, which pushes the installation into a ductwork assessment before anyone prices the unit itself. Electrical service is the second check: the panel has to support the load, and that gets confirmed on-site.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, sitting on a pad beside the house. It holds the compressor and the outdoor coil, which do the work of pulling heat from outside air. The indoor air handler mounts inside, usually in a closet, utility room, or attic, and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the indoor air handler through the wall or crawlspace. A thermostat goes on an interior wall where a homeowner can reach it, and it is wired back to both units to control the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your house.
