ACI Northwest has served North Idaho since 1992, and that includes Plummer. Set on the plateau above the south end of Lake Coeur d’Alene where the Palouse farmland meets the mountains, Plummer is the headquarters of the Coeur d’Alene Tribe and the gateway to Heyburn State Park and the Trail of the Coeur d’Alenes. It’s a rural community of farms, acreage homes, and year-round families, and we keep them comfortable through every season.
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 Farms & Rural Properties
Plummer homes tend to sit on larger lots and farmland, and many properties include a shop, barn, or outbuilding that needs heat of its own, which we can plan for alongside the main house. We handle heating repair, installation, and replacement, furnaces, heat pumps, and air handlers, and we service the boiler and radiant heat found in some older homes. With the plateau’s dry summers turning hot, a well-sized air conditioner or heat pump keeps the whole house comfortable, and ductless mini-splits are a clean fit for older farmhouses without ductwork.
Our Services
Built for Plummer
Many Plummer 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. Hard well water is tough on water heaters, so we keep tank and tankless systems running efficiently. Up on the plateau the winters are cold and snowy, the summers dry, and late summer brings wildfire smoke, so dependable heating, reliable cooling, and whole-home filtration all earn their keep here.

Plummer HVAC FAQs
Can you heat a shop, barn, or outbuilding?
Yes. Many Plummer properties need heating beyond the main house, and we can recommend the right solution for a detached space.
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.
My older farmhouse doesn’t have central AC. What are my options?
Ductless mini-splits are ideal for older homes without ductwork, adding efficient cooling and heating without a major remodel.
Does well water affect my water heater?
Well water tends to run hard, which shortens water heater life. Regular maintenance and the right system keep hot water reliable and efficient.
