A contractor diagnosing a heat pump failure in Vigo County first has to separate what weather has done to the system from what time and wear have done. 76 severe weather events were recorded in Vigo County, Indiana between 2015 and 2024. At that rate, severe weather is a regular feature of life for equipment here, not an occasional surprise. That means a refrigerant line showing stress or a contactor showing pitting gets read in the context of genuine cumulative load, and the repair scope follows from that. A unit that has run through repeated severe weather events may need a different set of decisions than one that simply aged out.
Ductwork laid down for one generation of equipment, then adapted for the next, tells a contractor less about what a repair will cost than what is inside the unit itself. Half the homes in Vigo County, Indiana were built in 1968 or earlier (2020-2024 ACS 5-year). A heat pump that has been running in a house of that vintage may predate the parts it now needs, and a contractor opening the system has to establish whether those components are still in production before a repair scope makes sense. If they are not, the job changes shape before pricing starts.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit sits outside the house and holds the compressor and the condenser coil. When a heat pump loses heating or cooling capacity, the compressor is one of the first things a contractor looks at. The condenser coil and the fan motor that draws air across it are checked alongside it.
Inside the house, the air handler contains the evaporator coil and the blower that pushes conditioned air through the home. The reversing valve, which controls the direction the system runs, sits in the outdoor unit and is a common point of failure when a heat pump gets stuck in one mode. Refrigerant lines connect both units and are inspected for leaks when pressures read low.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components are at issue in your specific system.
