A contractor quoting a heat pump installation in Madison County has to treat sizing as a site-specific calculation, not a product-line default. 576 severe weather events were recorded in Madison County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a system that is marginally sized or loosely installed will be running against real load from the start. Refrigerant line placement, equipment mounting, and airflow design all behave differently when the climate routinely pushes the unit hard. A contractor who accounts for that up front sets the system up to carry the load it will actually meet.
The electrical panel is where a heat pump installation in Madison County tends to run into resistance. Half the homes in Madison County, Alabama were built in 1992 or earlier (2020-2024 ACS 5-year). Housing from that era was commonly wired around equipment that drew differently than a modern heat pump does, and the service feeding the outdoor unit is what a contractor checks before anything else gets priced. Ductwork in a house of that vintage is worth inspecting too, but it is the panel capacity that decides whether the project moves forward on the first visit or requires additional work before the unit can go in.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchanges heat with the outside air. The indoor air handler mounts inside, usually in a closet, attic, or utility room, and it moves conditioned air through the home. Together these two units are what a contractor installs.
A refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it can read the living space accurately, and a condensate drain line carries moisture away from the air handler to a suitable drain point.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.
