A heat pump going into Coffee County needs to be sized for what this area actually demands, and that work starts before a contractor pulls a unit off a truck. 129 severe weather events were recorded in Coffee County, Tennessee between 2015 and 2024. At roughly that rate, severe weather is part of the normal operating environment, and a system sized to catalog minimums rather than local conditions will run harder and longer than it was built to. A contractor installing here accounts for that load when selecting equipment, placing the outdoor unit, and setting refrigerant charge.
Ductwork and electrical service sized for older equipment are what a contractor runs into across much of Coffee County's housing stock. Half the homes in Coffee County, Tennessee were built in 1986 or earlier (2020-2024 ACS 5-year). A heat pump pulls differently than what those systems were built around, and whether the existing ducts can move the air a new unit needs is answered by measuring, not by looking at the unit itself. If the ductwork falls short, that is the job that sets the budget, and the new equipment gets priced after it.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which do the main work of moving heat in or out depending on the season. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to wherever the air handler sits. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler for the coldest nights.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
