Ductless mini-splits · Spokane
Spokane mini-splits for the room the furnace never reaches
A Latah Valley bonus room at 88°F by late afternoon, an Audubon daylight basement stuck at 62, a Five Mile shop on a space heater. We install cold-climate ductless units for rooms like these and repair the ones already on the wall.
- Cold-climate only
- Primary-heat units that keep producing at −13°F, sized for Spokane Januaries.
- Any installer's unit
- Codes read and faults proven on systems we did not install.
- Circuit on the quote
- Dedicated 240-volt circuit and disconnect listed as their own line.
Spokane houses were built around a single heat source in the basement, and the rooms added since then are where the comfort complaints live. A room over the garage in Latah Valley or on Five Mile sits at the end of a duct run nobody sized for it. A finished daylight basement in Audubon-Downriver has one supply register and no return at all. An ADU behind a Perry District craftsman has no ductwork whatsoever. A ductless mini-split heats and cools each of those rooms on its own terms, without cutting into the original system or opening up plaster walls.
The same crew looks after units already installed around the city. When a head starts dripping, the outdoor unit disappears under a shell of ice in January, or the remote blinks a code and the room drifts warm, we pull the error history, check the charge with gauges and a scale, and confirm the failed part electrically before swapping anything. One written number follows, with the $99 diagnostic already counted in it, and a declined repair leaves you owing only the diagnostic. Most repairs wrap up during that first visit, and an ordered board never brings a trip charge for the return.
Mini-split problems and projects we see in Spokane
| What you notice | What it usually is | What we do |
|---|---|---|
| West-facing Kendall Yards condo can't keep up in July | The building system was never sized for that afternoon sun | Single-zone head sized to the room's actual load |
| ADU or detached shop with no heat source | Space heaters on extension cords and a breaker that trips | Cold-climate single-zone unit on its own dedicated circuit |
| Mini-split runs but barely heats or cools | Low charge from a flare leak, or a coil coated in biofilm | Leak repaired, system weighed in, coil and blower wheel cleaned |
| Water running down the wall under the head | Blocked or badly pitched condensate line, or a dead lift pump | Line cleared and re-pitched, pump replaced |
| Code blinking and the head shuts off | Sensor, indoor-outdoor communication or inverter fault | History pulled from the board, failed sensor or board proven, then replaced |
| Outdoor unit encased in ice | Defrost control fault, low charge or poor drainage under the unit | Defrost repaired, charge corrected, unit raised or drainage fixed |
Where ductless makes sense in Spokane, and where it goes wrong
Climate chooses the equipment. A standard mini-split gives up most of its heating output once the outdoor air falls into the low 20s, which describes an ordinary Spokane January night, so a unit that will be the only heat in a shop or an ADU needs to come from a cold-climate line built to keep heating at −13°F and below. We install Mitsubishi, Daikin and Fujitsu lines picked for those ratings and for parts we expect to still buy in Spokane fifteen years from now. We mount the outdoor unit on a bracket or stand, clear of drifted snow, so defrost water can drain away instead of building an ice dam under the coil.
Two other traps catch Spokane homeowners. Bargain units ordered online often have no parts supply in the United States, so the first failed board ends the machine. And a standard multi-zone system runs all its heads in one mode at a time, so the basement cannot heat while the upstairs cools on a mixed April afternoon. When that is the real need, two single-zone systems usually make the better design. Those questions get settled at the install site visit, which carries no charge, well before anything is ordered.
Older houses raise panel questions. Browne's Addition and the Perry District are full of 1920s electrical services that limit what can be added, and every mini-split needs a dedicated 240-volt circuit and a disconnect. Both go on the written quote as line items, along with the permit. On install day the line set is flared with a torque wrench, pressure-tested with nitrogen, then evacuated until a micron gauge proves it dry and tight before the stored refrigerant is released. The system is then run in heating and cooling before we pack up.
Mini-split repair and installation costs in Spokane
A single-zone cold-climate mini-split in Spokane starts at $3,350, and that starting price covers the equipment and the whole install, circuit and line set included. On the repair side, sealing a flare leak and weighing in a fresh charge starts at $450, and a replacement control board at $400. Read the repair and install figures alike as Spokane-area starting points for planning, not a quote: a repair is priced in writing after the $99 diagnostic, an install after the site visit, and a multi-zone system is quoted on request once that visit is done. There is up to $50 off an HVAC repair booked online, and up to $500 off a full-system install booked through the site-visit form, first-year tune-up included.

Questions we hear
Will a mini-split heat an ADU through a Spokane winter?
A cold-climate model will, with rated output down to −13°F, and that is the only class we specify when the mini-split is the main heat. A standard unit fades in the low 20s. We size the unit to the room, its insulation and its windows, and the quote lists the unit's heating capacity at low outdoor temperatures.
Our 1920s house has a small panel. Can it take a mini-split?
Often, yes. A single-zone unit needs a dedicated 240-volt circuit, and the site visit checks whether the existing service has room. If it does not, the panel upgrade appears as its own line on the quote, a common story in Browne's Addition, where the panel tends to be the bottleneck.
Can you repair a mini-split someone else installed?
Yes. Mitsubishi, Daikin, Fujitsu, LG, Gree, Pioneer and MrCool are all routine repair work for us. The technician reads the code history, confirms the real fault with a meter and gauges, and writes one price with the $99 diagnostic inside it. Flare leaks are the most common fault on units installed without a torque wrench; boards and sensors come next.
How often should the indoor heads be cleaned?
Rinse or vacuum the washable filters in each head every month or two while the system is working hard. A deep cleaning of the coil and blower wheel every couple of years keeps output up and clears the musty smell that comes from biofilm. If a head already smells or blows weakly, it is probably due now.
Can I buy a unit online and have you install it?
We will look at it, but many bargain units have no parts supply in the United States, and one failed board can end the machine. A unit we supply comes from a line with parts available locally for years, and a single written warranty covers both the equipment and the installation work.
