A contractor diagnosing a heat pump in Kings County starts with what the equipment has actually been running through. Homes in Kings County, CA run heat about six months a year, from November through April. Refrigerant circuits degrade under sustained heating cycles, and the reversing valve, which switches the system between heating and cooling, wears at its seals with each transition. A compressor that spent the cold months pushing heat into a house rather than out of it carries a different fatigue pattern than one that saw only light use, and a good repair quote accounts for that before it prices any parts.
Ductwork in a house this old has usually been rerouted, resealed, or sectioned at least once, and what it actually contains now differs from what any permit or visual inspection suggests. Half the homes in Kings County, California were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor diagnosing a heat pump here opens the unit and then follows the duct runs, because a refrigerant problem and a distribution problem can produce the same symptom at the register. What they find in the ducting decides whether the repair is a component swap or a broader fix.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. These are where most failures show up. A contractor will check the compressor for signs of electrical or mechanical fault, and the coil for damage, refrigerant issues, or anything blocking airflow.
The air handler lives inside, usually in a closet, attic, or utility room, and moves conditioned air through the house. It contains the evaporator coil and the blower motor, both of which a contractor examines when the system is heating or cooling poorly. The refrigerant lines running between the two units and the reversing valve, which switches the system between heating and cooling, are also on the inspection list.

Weather Events in Kings County That Stress HVAC Systems
Storms, temperature swings, and extreme conditions put direct load on heating and cooling equipment, accelerating wear and shortening the time between repairs. How hard a heat pump works over its life is shaped by where it runs, which makes local weather data a practical starting point for any repair conversation.
