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.

Electrical contractor, MissoulaGoogle review

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.

05 — Where we work

07 — Questions

The things people ask us

Straight answers, in the first sentence. If yours is not here, the phone number at the top goes to one of the owners.

Do mini-splits actually work in a Montana winter?
Yes. A cold-climate mini-split keeps producing usable heat well below zero, because variable-speed compressors can pull heat from outdoor air far past freezing. What decides whether yours performs is whether it was sized off a real load calculation for your house and whether it was properly evacuated and charged at commissioning. Neither of those is visible once the covers are on, which is why installation quality matters more than which brand is on the box.
Is a mini-split less expensive than adding ductwork?
In an older Missoula home, almost always. Retrofitting proper ductwork means opening walls and ceilings, losing closet space and paying for drywall repair afterwards. A mini-split needs one small penetration for the line set. The bigger the house and the more finished it already is, the further ahead ductless comes out.
Should I get a mini-split?
They are a strong fit for additions, above-garage living space, cold or hot spots the existing system never fixed, rooms you cannot get traditional heating or cooling into, finished homes that want air conditioning but have no furnace to attach it to, and anyone who wants different temperatures in different parts of the house. If your situation is none of those, we will tell you so rather than sell you one.
Do you charge for an estimate?
No. Estimates are free and you get a clear scope of what is needed and what we would do before there is any decision to make.
Do you offer after-hours or emergency callouts?
No. We run Monday to Friday, 8 to 5, and we would rather tell you that plainly than have you waiting on a call we cannot take. Inside those hours we answer quickly and get out fast, which is what our reviews say about us.
Is my furnace worth repairing or should I replace it?
Age against repair cost is the honest test. Under ten years old, most repairs are worth doing. Past fifteen, a large repair is usually money spent on borrowed time. A cracked heat exchanger is a replacement regardless of age, because that is a combustion safety problem rather than a comfort one.
