Half the homes in Dillingham Census Area, Alaska were built in 1985 or earlier (2020-2024 ACS 5-year). A house that old has almost certainly seen its heat pump components accumulate wear through winters that were never mild. When a contractor opens the unit, what matters is the condition of the refrigerant lines, the capacitors, and the contactors, and whether the parts those systems take are still in production. Stock of this vintage was built before the service intervals that extend equipment life became standard practice, so the opened unit often shows deferred wear rather than a single point of failure. The repair scope follows from what is found, not from what the permit says.
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 outdoor coil. The compressor is the part contractors look at early in a repair call: when it fails, the system moves no heat at all. The outdoor coil sits around it and is where dirt, ice, or physical damage shows up plainly.
Inside, the air handler or indoor coil sits in a utility space, attic, or closet and is where the refrigerant lines terminate on the indoor side. The expansion valve and the reversing valve are smaller components inside the system that control how refrigerant flows. Either can cause the unit to heat poorly, cool poorly, or behave differently in one mode than the other.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.
