Spokane WA Heat Pump Installation is a heat pump contractor providing ductless mini-split heat pumps 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 ductless mini-split puts the evaporator coil directly in the room it serves, which removes the duct losses entirely and makes it the obvious answer for houses that never had ducts in the first place. Spokane has a lot of these: older homes on electric baseboard, converted attics, detached shops and additions that were never tied into the main system. The install is comparatively clean, needing a three inch wall penetration for the line set, condensate and control wiring rather than sheet metal through the ceiling. Most single-head installations are finished in one day.
Most mini-splits arrive charged for a 25 foot line set. Longer runs need additional refrigerant weighed in, and shorter runs are left alone. Getting this wrong is one of the most common causes of poor performance on an otherwise correct installation.
Ductless equipment is reliable and the failures we get called to are almost always installation faults rather than equipment faults. These are the details that separate the two.
Head placement decides how well a ductless system works, and it is worth more discussion than most installers give it. A head mounted above a doorway looks tidy and throws air into a hallway. A head mounted on the long wall of the room it serves does the actual job. We walk the room with you and talk about where the air needs to go before anything gets drilled, because moving a head afterwards means patching drywall and re-running the line set.
Mount the head wherever the line set run is shortest and the drilling is easiest, usually high on the nearest exterior wall.
Place the head where the room's airflow actually needs it, then work out the line set route afterwards, even when that means a longer run and more line set cover.
Ductless heads are sized to the room, not the house, and oversizing is the classic mistake. An oversized head satisfies the thermostat quickly, shuts down and leaves the room with poor humidity control in summer and uneven temperatures in winter. Because inverter-driven equipment is most efficient in its mid range, a head that is modestly sized and runs long beats one that is generously sized and cycles.
We calculate the load for the specific room including its window area, orientation and how well it is connected to the rest of the house. A bonus room over a garage with three exterior surfaces behaves very differently from an interior bedroom of the same square footage, and a rule of thumb per square foot cannot see that difference.
A single-head ductless install is one of the more predictable jobs in this trade. Cost moves with the number of heads, the length and difficulty of the line set routing, and whether the electrical panel can accept the new circuit without modification.
Long line set routes are the usual surprise. A head on the opposite side of the house from the practical outdoor unit location can double the line set length and add hours of routing work, so we agree on that route with you before quoting rather than after.
We look at each room you want conditioned, discuss head placement against how the room is actually used, and identify the outdoor unit location.
Each room gets its own load calculation so the head is matched to that space rather than to a square footage rule of thumb.
Heads are mounted, the wall is cored and sleeved, line set is run inside covers, and flare connections are torqued to specification.
The system is nitrogen pressure tested, evacuated to a deep vacuum, charge is adjusted for the actual line set length, and operation is verified in both modes.
Ductless installs need clear access to one interior wall and the matching exterior wall, plus a route for the line set between them.
