A contractor quoting heat pump repair in Johnson County has to settle one question before anything else: what drove the failure. 177 severe weather events were recorded in Johnson County, Texas between 2015 and 2024. At that rate, stress from severe weather is a real variable in the condition of any system that has been running here for years, which means a refrigerant problem or a failed capacitor gets traced back to whether it wore out under heavy load or was simply never serviced. That distinction produces a different scope of work and a different parts list.
Half the homes in Johnson County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). A heat pump that has run through that much calendar time is likely on its second or third refrigerant standard, and the compressor, reversing valve, or control board inside it may draw from a parts lineage that has thinned out. Once a contractor opens the unit, the question is whether what needs replacing is still in production or has to be sourced as old stock. That answer sets the repair bill more than the labor does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. These are where a contractor starts when a heat pump stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each produce distinct symptoms that point the diagnosis in a clear direction.
The air handler lives inside, most often in a closet, attic, or utility room, and it contains the evaporator coil and the blower that moves conditioned air through the home. The reversing valve, which sits inside the outdoor unit, is the part that lets a heat pump shift between heating and cooling modes. When it sticks or fails, the system runs in only one direction regardless of what the thermostat calls for.
The drawing shows a typical layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

Severe Weather Events in Johnson County
Extreme weather puts real stress on heat pump equipment, pushing it harder and wearing components faster. How much of that stress a system absorbs depends on local conditions, which is why the weather record for this area is a repair factor, not just background.
