A contractor quoting a heat pump install in Limestone County starts with the climate before they open any product sheet. 106 severe weather events were recorded in Limestone County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, and a system sized for a calmer environment will be working outside its design range on a regular basis. That gap shows up in refrigerant line choices, in the capacity a contractor selects, and in how they approach the outdoor unit's placement and protection. Getting the sizing right the first time is harder here than the spec sheet alone suggests.
Ductwork laid in for a conventional system carries air at pressures and volumes that a heat pump does not match, and a house built to those older specifications may need the ducts assessed, modified, or replaced before a new unit can perform as rated. Half the homes in Limestone County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). That puts the existing duct layout at the center of what a contractor has to work through here, well before the new equipment gets priced. Panel capacity is a separate check: heat pumps draw differently than the systems that were standard when most of this county's homes went up, and the electrical service has to support what the new unit actually pulls.
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 condenser coil, which do the core work of moving heat between outside air and your living space. Inside, an air handler mounts in a utility closet, attic, or mechanical room and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the refrigerant that connects outdoor and indoor work. A thermostat mounts on an interior wall and gives you control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler for periods of very cold weather.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the setup in your house.

Severe Weather Events in Limestone County
Limestone County's climate puts real load on heating and cooling equipment, and that load is not uniform year to year. A heat pump sized and installed for local conditions handles demand better than one spec'd to a national average.
