A contractor quoting a heat pump installation in Winston County sizes the system for the local climate, but the weather record here does not push that calculation toward extremes. 75 severe weather events were recorded in Winston County, Alabama between 2015 and 2024. At that rate, severe weather is an event a system may encounter, not a condition it runs against year-round. Compressors that fail here are failing for the reasons most compressors fail: undersized equipment, a rushed install, or years without a filter change. A contractor assessing an existing system before replacement looks at those factors first.
Ductwork put in for a furnace and central air combination was not sized for the airflow a heat pump moves, and in Winston County much of the existing residential duct system predates heat pumps as a common choice altogether. Half the homes in Winston County, Alabama were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here opens that question early: whether the existing ducts can carry the new system, or whether the install price includes bringing them up to what the equipment actually needs. The electrical is a separate check. What the house already has behind its walls is what drives the scope of the job.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, which do the core work of moving heat between inside and outside. The indoor air handler mounts inside, usually in a utility closet, attic, or basement, and pushes conditioned air through the home. Both units arrive as separate pieces and get set in place during installation.
A refrigerant line set runs between the two units, carrying the working fluid that links them, and a condensate drain line carries moisture away from the air handler. A thermostat mounts on an interior wall and gives the homeowner control over the whole system.
