ACI Northwest has served the region since 1992, bringing the same crews and standards we’re known for across the Inland Northwest to Newman Lake. A quiet, wooded community wrapped around its namesake lake in the far east corner of Spokane County, just minutes from the Idaho line, Newman Lake is a mix of year-round homes, longtime family cabins, and larger custom lakefront properties. We keep all of them comfortable through the seasons.
We cover the whole home: heating, air conditioning, indoor air quality, electrical, and generators. We handle installation, replacement, repair, and maintenance.
Heating & Cooling Around the Lake
A lot of Newman Lake homes are part-time or seasonal, which puts a premium on heating that runs reliably when no one is there, and smart thermostats let you monitor and adjust a cabin from anywhere. Older lake cottages often were never built for ductwork, so ductless mini-splits are an ideal fit for efficient heating and cooling without a major remodel. For larger custom lakefront homes, properly sized and zoned systems keep every room comfortable. We handle heating repair, installation, and replacement, furnaces, heat pumps, and air handlers, and we service the boiler and radiant heat found in some homes.
Our Services

Built for a Rural Lake Community
Newman Lake is almost entirely on well and septic and sits off the natural-gas grid, which makes heat pumps and dual-fuel systems an efficient, practical choice, and where propane or electric heat is already in place, we service and upgrade those too. Set in the pine-forested foothills of Mount Spokane, the area sees cold, snowy winters and a late-summer wildfire smoke season, so dependable heating and whole-home filtration both matter here. We also handle the electrical work that often comes with a system upgrade and offer whole-home standby power for winter storms.

Newman Lake HVAC FAQs
I only use my lake place part of the year. Can you help me keep it protected while I’m away?
Yes. We install reliable heating and smart thermostats that let you monitor and adjust the temperature remotely, which helps protect a seasonal home through the winter.
My cabin doesn’t have ductwork. What are my options?
Ductless mini-splits are ideal for lake cottages and cabins without ductwork, adding efficient heating and cooling without a major remodel.
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 winter storms?
Yes. Whole-home standby generators keep your heat, well pump, and essentials running when a storm knocks out power, which matters in a rural lake community.
