Takes about a minute. No obligation.
A heat pump in Bexar County has been running against real weather pressure for its entire service life, and that history shows up inside the unit when a contractor opens it. 387 severe weather events were recorded in Bexar County, Texas between 2015 and 2024. At that rate, refrigerant lines, capacitors, and compressor windings carry wear that accumulates across seasons rather than arriving in one storm. A contractor quoting a repair here works out how much of that load a component has already absorbed before settling on a fix, because a part that looks marginal in a quieter climate is a likely failure point here.
Older housing stock carries older equipment, and in heat pump repair that gap between the building and what runs in it decides more than the diagnosis itself. Half the homes in Bexar County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A heat pump serving a house of that age has likely been through at least one prior replacement, and the unit a contractor opens may be far enough back in its production run that sourcing components requires more than a standard parts order. When a compressor or reversing valve turns out to take a discontinued part, the repair scope shifts entirely, and a homeowner gets a different conversation than the one they expected when they called.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. The compressor is where most repairs begin. When it fails, the system runs but moves no heat. The condenser coil surrounds it, and a bent or dirty coil will push the compressor to work harder than it should until something gives.
Inside, the air handler hangs in a closet, attic, or mechanical room and pulls household air across the evaporator coil and through the blower. The reversing valve lives in the outdoor unit and is what lets a heat pump shift between heating and cooling. The expansion valve and refrigerant lines connect the two units, and a slow refrigerant leak often traces back to a fitting or the coil rather than the lines themselves.
The drawing shows a typical heat pump layout, and a licensed contractor will assess which components apply to your specific setup.

Severe Weather Events in Bexar County
Extreme weather puts real stress on heat pumps, which have to work harder and longer whenever conditions swing hard in either direction. How often that happens in Bexar County shapes how much wear local equipment takes and how frequently repair needs come up.
