Family owned. Duluth grown.
Built on neighborly service, not call-center scripts.
Northland Air is owned and run by Kris Higgins, a journey-level technician who grew up working the Twin Ports. When you call us, you get a tech who lives in the neighborhood we serve, not a salesman in a polo who showed up to push a quote sheet.
We work on every major brand of furnace, boiler, AC, heat pump, and mini-split. Whether you want a tune-up before the cold sets in, a fix for a boiler that bangs every morning, or a full system you can hand to the next generation, we make the price clear before we start.
Veteran-owned. Locally run. 24/7 emergency line for no-heat calls in winter. We pull every permit our work requires.

How we work
A clear price before we start. A clean job before we leave.
Every job, every customer, every time. The process is the product.
Call or text
Talk to a real person in Duluth, not a national call center. We will book you the same day for no-heat or no-cool emergencies.
Diagnostic
$139 trip and diagnosis. We find the actual problem, not a list of upsells. The fee is waived when you approve a same-visit repair.
Flat-rate quote
You see the repair or install price up front. No hourly meter, no surprise line items, no “just one more thing” at checkout.
Clean, permitted work
We pull every permit our work requires, leave the job site cleaner than we found it, and back the labor for a full year.
The Northland Air difference
Why Duluth homeowners keep our number in the freezer door.
Veteran-Owned. Locally Run.
Kris is a journey-level tech who grew up in the Twin Ports. We answer our own phone, drive our own trucks, and put our own name on every install. No middlemen, no franchises.
5.0 Stars Across 50 Reviews.
The job is not done until you are happy. Our reviews come from real Duluth, Hermantown, and Superior WI homeowners who got the work they paid for and called us back the next season.
Same-day service. Real Duluth phone.
No-heat in January? No-cool in July? Call us before lunch and a tech will be on your porch by dinner. That is the Northland Air promise.
What homeowners say
Real Duluth reviews, no stock photos.
Kris came out at 9pm on a Saturday in January when our boiler quit. Had it firing again in under an hour and the price was exactly what he quoted on the phone. We will not call anyone else.
Sarah K.Lakeside, Duluth
We had three quotes for a new heat pump. Northland Air was not the cheapest but they were the only one who actually looked at our duct sizing and our load. The install was clean, on time, and our power bill dropped 18 percent that winter.
Mike T.Hermantown
The crew that put our mini-split in our finished attic was professional, polite, and left it cleaner than they found it. They also took the time to show me how the remote worked. That kind of small thing is why we tell our neighbors.
