A heat pump repair in Medina County rarely comes down to one obvious failure. 88 severe weather events were recorded in Medina County, Texas between 2015 and 2024. At that rate, the system has been cycling hard through real weather loads season after season, and the wear spreads. Contractors working these jobs find that refrigerant-side components, capacitors, and contactors all carry the accumulated load, so a repair that starts with one failed part often surfaces a second that was close behind it.
Half the homes in Medina County, Texas were built in 1996 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house built around that year has probably had components replaced at least once, and the refrigerant lines and coil assemblies inside it carry the record of that work. When a contractor opens the unit, the question is whether the failed component can be sourced. Some parts for systems of that vintage are still manufactured; others are not, and that determines whether the repair is a straightforward fix or a conversation about what comes next.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. These are where most faults begin. A failed compressor stops the system entirely; a damaged or dirty coil starves it of the heat exchange it depends on. A contractor opens this cabinet first.
Inside, the air handler contains the evaporator coil and the blower that moves conditioned air through the house. The reversing valve, which tells the system whether to heat or cool, sits in the refrigerant line between the two units. The expansion valve and refrigerant lines connect everything, and a leak or a blockage anywhere in that path will show up as a symptom somewhere else.
The drawing shows a typical heat pump layout, and a licensed contractor determines what applies to the specific equipment and configuration in your home.
