A contractor quoting a heat pump repair in Union County has to settle one question before anything else: what actually wore this part out. 82 severe weather events were recorded in Union County, Kentucky between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a steady grind that explains compressor failures or refrigerant loss on its own. Age and installation quality are the more likely culprits, and a good diagnosis works through those first. A system that has been undercharged since the day it was installed will fail on a calm afternoon just as readily as after a storm.
Ductwork in a house built for earlier technology picks up a long record of use, and by the time a heat pump repair call comes in, that record shows up as blocked passages, degraded seals, and airflow that no longer matches what the equipment expects. Half the homes in Union County, Kentucky were built in 1976 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock this old will often find the unit itself is a straightforward fix, while the duct runs feeding it are where the hours go. Cracked insulation, separated joints, and years of particulate buildup change what the repair costs and what it fixes.
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. The compressor is usually where a contractor starts: when it fails, the system runs but moves no heat. The condenser coil sits around it, and a damaged or dirty coil causes the same dead-air symptom through a different path.
The air handler lives inside, most often in a utility closet or attic, and it holds the evaporator coil, the blower motor, and the expansion valve. A failing blower motor cuts airflow through the house. The expansion valve and the evaporator coil are the pieces a contractor checks when the system runs but cooling or heating is weak.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to your specific house and system.
