A heat pump repair quote in Glenn County starts with what the compressor and reversing valve have already been through. Homes in Glenn County, CA run heat about six months a year, from November through April. Heating duty is hard on the refrigerant circuit in ways that cooling duty is not: the system pulls heat from cold outdoor air, which means the compressor is working against poor conditions every time temperatures drop at night. A contractor checking a struggling unit looks at the reversing valve first, then the refrigerant charge, because those are the components that absorb the stress of long heating cycles.
Ductwork and wiring in a house this old were adapted over the years to whatever system moved in, and the heat pump a contractor opens today is a later addition to that story. Half the homes in Glenn County, California were built in 1977 or earlier (2020-2024 ACS 5-year). That means the repair question lands squarely on the unit itself: what its compressor shows when opened, and whether the parts it takes are still in supply. A refrigerant circuit that has been running hard through Glenn County summers tells its own condition through what a contractor finds inside, and that finding drives the scope and the bill.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits on a pad outside the house and holds the compressor and condenser coil. The compressor is where most repair work begins. When it labors or fails, the whole system feels it. The condenser coil wraps around it and sheds or pulls heat through the refrigerant lines that run between the two units.
Inside the house, the air handler holds the evaporator coil and the blower fan that moves conditioned air through the home. The reversing valve, which switches the system between heating and cooling, sits in the outdoor unit and is a common focus when the system runs but delivers the wrong temperature. The expansion valve and refrigerant lines connect both sides and are checked whenever pressure or output is off.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.
