ACI Northwest has served the region since 1992, bringing the same crews and standards we’re known for across the Inland Northwest to Greenacres. Sitting at the fast-growing east end of Spokane Valley toward Liberty Lake and the Idaho line, Greenacres grew out of old fruit-orchard country into a mix of new subdivisions, established mid-century homes, and manufactured homes. Each of those calls for a different approach, and we handle all of them.
We cover the whole home: heating, air conditioning, indoor air quality, water heaters, electrical, and generators. We handle installation, replacement, repair, and maintenance.
HVAC for a Growing East-Valley Community
Greenacres has been adding new subdivisions for years, and those homes benefit from new-construction and high-efficiency systems sized and installed right the first time, including zoned setups for larger floor plans. The older mid-century homes are a different story: many run aging equipment that’s ready for an efficient replacement, and those that never had central AC are ideal candidates for ductless mini-splits. Greenacres also has a large share of manufactured and mobile homes, and we install and service heating and cooling suited to them, from furnaces and heat pumps to ductless systems. Where older homes run boiler or radiant heat, we service, repair, and replace those too.
Our Services
Built for Greenacres
The Inland Northwest climate shapes the work here: cold, snowy winters, hot dry summers that make reliable cooling worth planning for, and a late-summer wildfire smoke season when whole-home filtration earns its keep. We also keep water heaters running reliably with tank and tankless service, and handle the electrical work that often comes with a system upgrade. Whatever the age or style of your Greenacres home, we match the system to it.

Greenacres HVAC FAQs
We’re building in one of the new Greenacres subdivisions. Can you handle new-construction HVAC?
Yes. We size and install complete new-construction systems, including high-efficiency and zoned setups, done right the first time.
Do you service manufactured and mobile homes?
Yes. Manufactured and mobile homes have specific heating and cooling needs, and we install and service systems suited to them, including ductless.
My older home doesn’t have central AC. What are my options?
Ductless mini-splits are an excellent retrofit for homes without existing ductwork, delivering efficient cooling and heating without a major remodel.
How often should I service my system?
A heating tune-up in the fall and a cooling tune-up in the spring is the cheapest way to avoid a breakdown in demanding weather.
