Whitefish Heating, Cooling & Quiet Comfort
Whitefish comfort without the franchise script. Honest as a Montana handshake.
Second homes and year-round houses here want quiet systems, smart zoning, and ductwork that doesn’t roar in a timber-frame great room. Western Sky serves Whitefish from Columbia Falls with that premium bar — and the same upfront pricing we publish for the corridor.
Cold-climate heat pumps, wildfire-season IAQ, and custom fittings from our fab shop show up often on Whitefish jobs. We’re not a Kalispell-only template page with the town name swapped. Call 406-296-3336 or send the form to schedule.
Whitefish HVAC, with a premium bar
Natural gas through NorthWestern Energy heats most Whitefish homes. Mountain-side residences above town often use propane, and newer luxury builds increasingly include electric heat pumps as a primary or backup heat source. We handle furnaces, heat pumps, boilers and hydronic, IAQ, and water heaters. Call 406-296-3336 or use the form if you’re not sure whether a job is water-heater work we do or something that needs a licensed plumber.
Quiet-path duct and radiant floor heat come up on timber-frame and custom jobs. Fall is the busiest maintenance season, especially as vacation homes prepare for winter.
Resort town, year-round comfort
Downtown Whitefish has older cottages and mid-century homes with character and, occasionally, aging ductwork. The Wisconsin Avenue area offers established residential neighborhoods. Iron Horse features newer construction with modern systems. South Whitefish includes a mix of housing ages and styles.
The Highway 40 shop in Columbia Falls is about 20 minutes by road. Highway 40 and US-93 stay well-maintained through winter, though Big Mountain Road access can be slowed by heavy snow. Same crew, same written pricing.

What you can count on
Frequently asked questions
Straight answers for Flathead homeowners — phones, service area, and what we do (and don’t) advertise.
What phone number should I save for Western Sky in Columbia Falls / the Flathead?
406-296-3336 — that’s our published Columbia Falls / Flathead residential number. Call that number or use the form on this site.
Do you really come to Whitefish?
Yes. We’re based at our Columbia Falls shop on Highway 40 and schedule the corridor — Columbia Falls, Whitefish, and Kalispell — as capacity allows. Hungry Horse may be available as an optional nested corridor stop; confirm your address when you call 406-296-3336 or send the form.
Is there a different number for Bozeman?
Yes. Bozeman and the Gallatin Valley publish their own number on Bozeman pages. Don’t use the Columbia Falls number as the Bozeman NAP, or vice versa. This page is Flathead residential service — save 406-296-3336.
What about the old Denning number 892-0111?
Legacy 406-892-0111 may still forward into our Columbia Falls line, but it is not a number to save or publish. Save 406-296-3336.
Are you the old Denning Sheet Metal?
Same Columbia Falls shop on Highway 40 (3580 MT-40), new ownership as Western Sky Heating & Cooling (formerly Denning Sheet Metal). A lot of Flathead folks already know the Denning name — and that recent years of service needed a reset. That’s what we’re here for. Call 406-296-3336 or use the form.
Did you merge Denning’s Google reviews into Western Sky?
No. We keep the verified Western Sky listing and mark Denning permanently closed — not merged. Heritage carries through honest naming and citations, not by importing old ratings.
What’s the shop address and website?
3580 MT Hwy 40 W / 3580 MT-40, Columbia Falls, MT 59912 · westernskyhvac.com · Call 406-296-3336.
What heating and cooling work do you do from this hub?
Residential service and replacement from Columbia Falls: furnaces, air conditioning, cold-climate heat pumps, boiler and hydronic heat, indoor air quality, and ductwork built in our own shop. We’re a Lennox dealer for Columbia Falls residential. Call 406-296-3336 or use the form to schedule.
Do you offer maintenance memberships?
Yes — seasonal tune-ups and member preferences as defined on the plan page. Exact monthly pricing publishes when our price book is locked; until then, call 406-296-3336 or use the form and we’ll explain today’s options honestly.
Does Western Sky do plumbing or install water heaters?
Yes. We install and service water heaters. General plumbing is a different conversation — if you’re not sure whether a job is water-heater work we do or something that needs a licensed plumber, call 406-296-3336 and we’ll tell you straight.
Why aren’t the Whitefish and Kalispell URLs at the root?
Our site nests corridor towns under the Columbia Falls engine — for example /columbia-falls/whitefish/... and /columbia-falls/kalispell/.... That’s intentional architecture, not a mistake.
How do I book service?
Call 406-296-3336 or use the form on this page. We’ll get you on the schedule and explain next steps.
