A contractor diagnosing a heat pump here works out how hard the compressor and reversing valve have been running before settling on a repair scope. Homes in Humboldt County, CA run heat about eight months a year, from October through May. Repeated heating cycles load the reversing valve in ways that straight cooling systems never face, and a compressor that has been switching direction all winter shows fatigue in its valves and windings before it shows it anywhere else. On a repair call, a Humboldt County contractor prices the compressor health first, because that is where the season's work lands.
Refrigerant lines in a house that has changed systems more than once tend to show the history: connections made for one unit and adapted for the next, bends that reflect where walls were and where they are now. Half the homes in Humboldt County, California were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this finds that the repair scope sometimes widens once the covers come off, because what connects the indoor and outdoor units has been touched before, and those prior repairs set the condition of the fittings and charge levels a technician now has to work from.
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 the condenser coil. These are the pieces a contractor looks at early. When the compressor fails, the system stops moving heat entirely. When the coil is damaged or blocked, the unit runs but accomplishes little.
Inside, the air handler mounts in a closet, attic, or utility room and contains the blower fan and the evaporator coil. The reversing valve, which sits within the outdoor unit, is what lets a heat pump heat and cool. A fault there shows up as the system working in only one direction, or refusing to switch at all.
The drawing shows a typical layout, and a licensed contractor determines which components apply to the specific system and house.

Severe Weather Events in Humboldt County
Weather puts hours on heating and cooling equipment. A heat pump working harder through rough conditions accumulates wear faster, and when repairs become necessary, the right contractor is one who knows what local conditions demand.
