A contractor quoting a heat pump installation in Lee County sizes the system for the local climate, but that sizing question is not what drives most of what they find when they open a failing unit. 46 severe weather events were recorded in Lee County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and a heat pump that has underperformed here was more likely installed with undersized refrigerant lines or skipped startup commissioning than worn down by storm load. What a contractor has to establish before they quote a replacement is whether the original install was done to spec, because a correctly specified and commissioned unit handles this county's weather record without difficulty.
Ductwork laid down for a conventional system carries air at a different velocity and volume than a heat pump needs, and in a county where a large share of the housing stock predates the spread of heat pump technology, that gap is what a contractor has to resolve before anything else on an installation job. Half the homes in Lee County, Texas were built in 1992 or earlier (2020-2024 ACS 5-year). A contractor working through an installation here measures the existing duct runs for static pressure and return capacity, because those numbers decide whether the ducts stay, get modified, or get replaced. The electrical service gets the same look, since a heat pump's draw at startup has to match what the panel can deliver.
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 together do the core work of moving heat between inside and outside. The indoor air handler mounts inside, often in a closet, attic, or utility room, and pushes conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or along the exterior of the house to carry refrigerant between them. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the air handler to a nearby drain, carrying away moisture pulled from indoor air.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific conditions of your house.

Severe Weather Events in Lee County
Local weather puts a measurable load on heating and cooling equipment, and that load shapes what a system needs to handle over its working life. A heat pump sized and installed for this county has to hold up under whatever the climate here delivers.
