Spokane WA Heat Pump Installation is a heat pump contractor providing heat pump thermostat installation for homeowners and property owners across Spokane County, WA and out to the Idaho state line. Every job starts from a load calculation rather than the size of whatever came out.
A heat pump needs a thermostat that understands it. A standard thermostat has no concept of a reversing valve, no way to stage backup heat correctly and no lockout to stop expensive resistance heat running when the heat pump could handle the load alone. Fitting the wrong thermostat, or fitting the right one and leaving it on default settings, quietly costs a great deal over a winter. The physical installation takes under an hour. The configuration is where the value is, and it is the part most commonly skipped.
Setting a lockout temperature stops resistance backup heat engaging above a chosen outdoor temperature, where the heat pump can comfortably carry the load alone. Left unset, backup heat contributes far more often than it needs to, and it converts electricity to heat at exactly one to one.
Thermostats are the cheapest component in the system and one of the largest influences on what it costs to run.
Deep temperature setbacks work differently on a heat pump than on a furnace, and this catches people out. A furnace recovers a large setback quickly using high output. A heat pump recovering the same setback often triggers backup resistance heat, which costs far more than the setback saved. Modest setbacks, or a thermostat with intelligent recovery that starts early and avoids backup heat, are the better approach here. We explain this at handover because it changes how you should use the system.
Fit the thermostat the customer bought, connect the wires that were there before, confirm it turns on and leave the defaults in place.
Confirm compatibility with the actual equipment, configure the reversing valve logic, set backup heat staging and lockout properly, and explain how setbacks should be used on a heat pump.
The configuration items that matter most are the reversing valve logic, the number of heat pump and auxiliary heat stages, the auxiliary heat lockout temperature, the compressor lockout temperature if applicable, and the minimum compressor off time that protects against short cycling.
The auxiliary lockout is the one with the largest financial effect. It prevents electric resistance backup from engaging above a set outdoor temperature, on the basis that the heat pump can carry the load alone in milder conditions. A system left on defaults will frequently call for backup heat far more readily than it needs to, and because resistance heat has a coefficient of performance of exactly one, every hour it runs unnecessarily is money spent for nothing.
Thermostat installation is a short job unless the wiring at the wall does not support the chosen device. The most frequent complication in older Spokane homes is the absence of a common wire, which either needs running or working around with an adapter.
Configuration time is included rather than charged separately. Fitting a heat pump thermostat and leaving it on defaults would take less time and cost you considerably more over a winter, so we treat the setup as part of the job.
We confirm the thermostat suits your specific equipment, since variable-speed and communicating systems often need a manufacturer controller.
The existing wiring is checked for the terminals the new thermostat needs, particularly the reversing valve terminal and a common wire.
The old thermostat is removed, the sub-base is mounted and wired, and connections are confirmed at the air handler end as well.
Reversing valve logic, staging and backup heat lockout are set for your system, and we explain how setbacks should be used on a heat pump.
Thermostat work is quick, and almost all of the delays come from wiring that is not what anyone expected.
