Takes about a minute. No obligation.
A contractor quoting a heat pump repair in Waller County starts from the fact that the system has been working against genuine weather pressure, not a mild background. 33 severe weather events were recorded in Waller County, Texas between 2015 and 2024. At that rate, wear on compressors, reversing valves, and capacitors accumulates from conditions that are part of normal operation here. A part that failed may have failed early because of that load, or it may have simply reached the end of its service life. The contractor has to open the system and look at what is actually there before either answer is available.
Heat pump systems running in houses built in the late nineties are old enough that the refrigerant lines, contactors, and control boards they take have cycled through at least one product generation since the original install. Half the homes in Waller County, Texas were built in 1998 or earlier (2020-2024 ACS 5-year). A contractor opening a unit in stock this age has to verify that the specific components a repair calls for are still in production, because substitutes sometimes exist and sometimes do not, and that answer changes the scope of the job before any labor estimate is written.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits on a pad outside the house. The compressor is where a contractor starts when the system stops moving heat altogether. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each kill the system in a different way, and each leaves its own set of signs.
Inside the house, the air handler holds the evaporator coil and the blower fan, usually in a closet, attic, or utility room. The expansion valve connects the two units and controls refrigerant flow between them. A contractor also checks the reversing valve, which is the part that lets a heat pump heat in one season and cool in another, because when it sticks or fails, the system runs in only one mode.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply to your specific house and setup.
