A contractor called out to repair a heat pump here has to settle one question before they can say what failed and why: how much of the system's wear was driven by the conditions it has been running against. 94 severe weather events were recorded in Galveston County, Texas between 2015 and 2024. At roughly the national midpoint for severe weather, this county sits in a range where stress on a heat pump is neither negligible nor overwhelming, which means the failure could go either way. A refrigerant leak traced to a corroded line set reads differently in a place with this kind of weather record than in a sheltered market, and a contractor quotes accordingly.
Ductwork and wiring that came with a house often outlast two or three rounds of equipment, which means the heat pump a contractor opens today was not what the house was built for. Half the homes in Galveston County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A system installed into stock like this has been adapted, not matched, and the repair scope follows from what the refrigerant circuit, the coil, and the electrical connections inside the unit actually show once the panels come off. Parts availability is the variable that drives the job from there, because manufacturers do not carry everything a system of this vintage takes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize: a metal cabinet that sits on a pad outside the house and holds the compressor and outdoor coil. When a heat pump stops heating or cooling properly, those two components are where a contractor looks first. A failed compressor means the system cannot move heat at all. A damaged or dirty outdoor coil means it cannot shed or absorb heat efficiently.
Inside the house, the air handler contains the indoor coil and the blower that pushes conditioned air through the home. A refrigerant line set connects the two units and carries the working fluid between them. When airflow drops, temperatures swing unevenly, or the system short-cycles, the indoor coil, blower motor, and the condition of those lines all come under inspection.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific system and setup in your home.

Severe Weather Events in Galveston County, Year by Year
Weather puts hours on HVAC equipment. In Galveston County, what the climate asks of a heat pump shapes how hard that system works and where it tends to fail first, which makes repair history here a local question, not a general one.
