ACI Northwest has served the region since 1992, bringing the same crews and standards we’re known for across the Inland Northwest to Otis Orchards. A semi-rural community at the east end of the valley, north of the Spokane River and just west of the Idaho line, Otis Orchards grew out of Washington’s first commercial apple-growing region and still carries that character: larger lots, acreage parcels, hobby farms, and a mix of original farmhouses and newer custom builds. That variety is exactly what we’re built for.
We cover the whole home: heating, air conditioning, indoor air quality, electrical, and generators. We handle installation, replacement, repair, and maintenance.
HVAC for Acreage & Orchard-Country Homes
Lots here run from half an acre to several, and many properties include a shop, barn, or outbuilding that needs heat of its own, which we can plan for alongside the main house. The housing mix is wide: original early-1900s farmhouses and older ranch homes often run aging equipment that’s ready for an efficient replacement, newer custom builds call for high-efficiency systems and zoning, and we install and service heating and cooling suited to manufactured homes as well. We handle furnaces, heat pumps, and air handlers, and we service the boiler and radiant heat found in some older homes. For homes without central cooling, ductless mini-splits are a clean, efficient fit.
Our Services

Built for Otis Orchards
Many Otis Orchards properties sit on well and septic and off the natural-gas grid, which makes heat pumps and dual-fuel systems an efficient choice, and where propane or electric heat is already in place, we service and upgrade those too. With cold, snowy winters, hot dry summers, and a late-summer wildfire smoke season, dependable heating, reliable cooling, and whole-home filtration all earn their keep here. We also handle the electrical work that often comes with a system upgrade and offer whole-home standby power for the winter storms that can cut power to rural properties.

Otis Orchards HVAC FAQs
Can you heat a shop, barn, or outbuilding?
Yes. Many Otis Orchards properties need heating beyond the main house, and we can recommend the right solution for a detached space.
I have an older farmhouse with aging equipment. Repair or replace?
We’ll give you an honest recommendation. Older systems are often cheaper to replace with a high-efficiency unit than to keep repairing, and we’ll lay out the numbers.
My property is on a well and septic and off natural gas. What heating fits best?
Heat pumps and dual-fuel systems are often the most efficient choice, and we service propane and electric systems as well.
Do you install backup power for rural properties?
Yes. Whole-home standby generators keep your heat, well pump, and essentials running when a winter storm knocks out power.
