A heat pump install in Harris County starts with what the house actually demands, not with assumptions about weather punishing the equipment. 71 severe weather events were recorded in Harris County, Georgia between 2015 and 2024. At roughly the national median or below, that record means severe weather is an occasional fact of life here, not a standing load the equipment fights year-round. A contractor quoting a new system still has to size it for the structure, the duct layout, and how the house retains heat or sheds it. Those variables drive the spec. The climate, at this rate, does not.
Ductwork and electrical service installed in a house built around that era were sized for equipment generations that still resemble what runs today, which means a contractor assessing a heat pump job here finds infrastructure that is worth measuring rather than assuming away. Half the homes in Harris County, Georgia were built in 1997 or earlier (2020-2024 ACS 5-year). That is enough recent history that the ducts and panel in a typical house are a real starting point, not a liability to price around before anything else is opened. What a contractor checks is whether the existing runs actually move the air a heat pump needs, and whether the panel carries the load, not whether the house itself is the obstacle.
The Parts of a Heat Pump in a New Installation
The outdoor unit sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a closet, attic, or utility room and pushes conditioned air through the home. A line set of copper tubing runs between the two units, carrying refrigerant back and forth.
The thermostat goes on an interior wall and is what the homeowner uses to set temperatures and switch between heating and cooling. Most heat pumps also include a reversing valve inside the outdoor unit that lets the system run in either direction, and an expansion valve that controls refrigerant flow between the coils.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly what applies to this house.

Weather puts a load on heating and cooling equipment, and that load varies by where you live. A heat pump sized and installed for local conditions handles the work better than one that was not.
