ACI Northwest has served North Idaho and the Silver Valley since 1992, and that includes Kellogg. A historic silver-mining town tucked into the Coeur d’Alene Mountains, Kellogg has reinvented itself around Silver Mountain Resort, and its homes reflect that: preserved mining-era houses downtown alongside newer resort condos and mountain vacation homes. In a valley that sees serious snow, dependable heating is not optional, and we know how to work on all of it.
We cover the whole home: heating, air conditioning, indoor air quality, water heaters, electrical, and generators. We handle installation, replacement, repair, and maintenance.
Heating Built for Mountain Winters
Kellogg sits high in the mountains and takes on some of the heaviest snow and coldest winters anywhere we serve, so your heating system carries the household for months at a time. We handle heating repair, installation, and replacement, furnaces, heat pumps, and air handlers. Many of Kellogg’s older mining-era homes were built around boiler and radiant heat, and we service, repair, and replace those systems, keeping radiators and hydronic heat reliable through a hard winter. For resort condos and mountain vacation homes, ductless mini-splits deliver efficient heating and cooling, and smart thermostats let you keep a second home protected and monitored while you’re away.
Our Services
Built for the Silver Valley
Kellogg’s older housing stock rewards a contractor who’s actually worked on historic homes: tighter mechanical spaces, aging equipment, and retrofit challenges that reward doing it right. Some properties sit off the natural-gas grid, where heat pumps, dual-fuel systems, and the propane or electric heat already in place all have their role, and we service them all. Hard water is tough on water heaters, so we keep tank and tankless systems running efficiently, and with a late-summer wildfire smoke season in the mountains, whole-home filtration is worth having.
