A contractor quoting a heat pump installation in Giles County has to account for what this area actually demands of the equipment, and the weather record is only part of that picture. 71 severe weather events were recorded in Giles County, Tennessee between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means the sizing decisions and installation details a contractor works through carry more weight than storm exposure does. Compressor placement, refrigerant line length, and how well the air handler is matched to the load of the house are what determine how the system runs across its life.

Ductwork laid down for older heating systems was designed around different airflow volumes than a heat pump moves, and in a county where older housing is the norm, that gap is where a heat pump installation either comes together or gets complicated. Half the homes in Giles County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor quoting a job in stock like this opens registers, checks trunk dimensions, and confirms the existing runs can handle the system's supply requirements before anything else gets priced. Electrical service gets the same look, since a heat pump's draw has to match what the panel can deliver. The unit itself is a known quantity; what surrounds it in the house is what the quote is actually built around.
What Gets Installed With a New Heat Pump

The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the condenser coil, which are the heart of the system. Inside, the air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. The thermostat goes on an interior wall where the homeowner can reach it, and it ties the whole system together by telling both units when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specific conditions of your house.
