A contractor quoting a heat pump installation in Orange County has to account for what the local climate actually demands before settling on equipment, refrigerant line routing, or mounting position. 36 severe weather events were recorded in Orange County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of operating conditions here, and a system spec'd without accounting for it will be working harder than its design intended from the first season. The contractor's job is to size and position the unit around that load, not around catalog defaults.
Ductwork laid down for an older system was sized around how that system moved air, and a heat pump moves air differently. Half the homes in Orange County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). When a licensed contractor quotes a heat pump installation in Orange County, the duct layout is what they have to assess first: whether the runs, the returns, and the static pressure the existing system lives with will carry what the new unit puts through them. Electrical service matters too, but ducts are the variable that most often changes the scope of the job.
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. The indoor air handler mounts inside, usually in a closet, attic, or utility space, and pushes conditioned air through the home. These two pieces are the core of what a contractor puts in.
A refrigerant line set runs between the outdoor and indoor units, carrying the working fluid that links them. An expansion valve sits inside the system and controls the flow of that refrigerant. A thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor will determine what applies to your specific house.

Severe Weather History in Orange County
Heat pumps work against whatever the outside air throws at them, so local weather patterns shape how hard the equipment runs and how well it holds up over time. That makes the storm record for this area a real factor in sizing and installing a system that fits the load.
