A contractor quoting a heat pump installation in Chilton County has to settle the sizing question before anything else, because an undersized or oversized unit will underperform regardless of what the weather asks of it. 66 severe weather events were recorded in Chilton County, Alabama between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means the variables a contractor controls during installation carry more weight than the ones the sky provides. Slab placement, refrigerant charge, and duct work determine how the system runs for years. Get those wrong and the weather never has to be severe for the equipment to struggle.
Ductwork laid down for a gas furnace or a window unit carries assumptions about static pressure and flow that a heat pump does not share. Half the homes in Chilton County, Alabama were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here has to assess what the existing duct system will actually deliver before settling on equipment, because a mismatch between the distribution system and the new unit shows up in comfort and efficiency from the first season. That assessment changes the scope of the job more than the choice of unit does.
What Goes Into a Heat Pump Installation
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. The indoor air handler mounts inside, usually in a closet, attic, or utility room, and moves conditioned air through the home. Together these two units do the core work of the system.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over temperature. The condensate drain line runs from the air handler to a nearby drain, carrying away moisture pulled from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your house.
