03 — What people say
5.0 stars, 40+ reviews
The best rating of any HVAC contractor in Missoula. In the customers’ own words, unedited.
As an Electrical Contractor there are multiple things that I look for when hiring out subs or recommending them to my clients. The boys at 406 Heating and Cooling are absolutely hands down the best HVAC contractor that I recommend whenever anyone asks for it. They have time and time again, come in within or below customers budget and done amazing work. They are knowledgeable ,craftsmen and most importantly take pride in what they do. Their communication is top notch.
“I wasn't able to be there for the service appointment, but Ethan and Robert worked directly with my family while I was at work. They quickly diagnosed and fixed our furnace issue, and my wife and elderly mother both commented on how professional, respectful, and easy they were to work with.”
“AMAZING SERVICE. We had originally hired another HVAC company in Missoula and we're incredibly disappointed with their service so we hired 406 Heating & Cooling and they were 1000000x times better.”
“406 Heating and Cooling were very quick in getting us a quote, installing our new unit and removal of our old unit. They were very professional and I will certainly be calling them in the future with any issues with HVAC.”
“We needed an entire system install. They came out and gave us a clear estimate of what was needed and what they would do. they didn't charge us for an estimate!”

04 — Why 406
Two owners, and they do the work
406 is Ethan and Robert. When you book a job, they are the ones who turn up and do it. Both of them get named in our reviews, which is not something a big shop can say.
- Veteran-owned, Montana-built
- Born and raised here. The same discipline that served the country is what shows up on the jobsite.
- No pressure, ever
- We will tell you when a repair is not worth the money and when you do not need the bigger system. Our reviews say this better than we can.
- Free estimates
- A clear scope of what is needed and what we would do, at no charge and with nothing attached to it.
- Mini-split specialists
- Ductless is what we install more of than anything else, and it is the right answer for a lot of older Missoula homes.
