Sizing a heat pump for Greene County means answering a question a generic load calculator skips: how far outdoor temperatures drop in the coldest weeks, and whether the unit's rated heating capacity holds there. Homes in Greene County, MS run heat about five months a year, from November through March. Across those months, a heat pump's ability to move heat into the house shrinks as outdoor air gets colder, so a unit that tests fine in mild weather can leave a house short on the hardest nights. A contractor has to establish the low-end temperatures this house actually sees before settling on capacity, and has to price backup heat into the install rather than treat it as optional.
Ductwork designed around a previous generation of central equipment does not automatically carry what a heat pump needs to push through it. The geometry, the returns, the static pressure a given layout produces: these are what a contractor has to measure before the unit itself can be specified. Half the homes in Greene County, Mississippi were built in 1987 or earlier (2020-2024 ACS 5-year). That share of the housing stock was built for systems that predate the heat pumps now replacing them, and the duct runs reflect that. A contractor pricing a heat pump installation here opens the duct question first, because what the existing layout will and will not carry determines what the job actually costs.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the main coil. The indoor air handler mounts inside, most often in a utility closet, basement, or attic, and it moves conditioned air through the home. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Both the line set and the thermostat are part of the installation, not afterthoughts.
The drawing shows a typical layout, and a licensed contractor determines what fits the configuration of your specific house.
