5.0 stars across 50 reviews. Real Twin Ports homeowners.
No incentivized reviews, no review-collection bots. Just what real Duluth, Hermantown, Superior WI, Two Harbors, and Cloquet homeowners said after we worked on their homes.
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.

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.

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.

Our cast-iron boiler is from 1956 and most contractors will not touch it. Northland Air not only services it, they walked us through what it would take to keep it running another 20 years vs converting to a modern boiler. Honest, patient, no pressure.

Furnace died at 6am on a Tuesday in February. Called Northland Air at 6:15. Tech was at my door at 8am with the part already on the truck. Heat back on by 8:45. Best service experience I have ever had with a trade.

We have a seasonal cabin off Highway 61. Northland Air does our spring startup and fall shutdown every year. Pricing is fair, they are reliable, and they actually return calls. Cannot recommend more.

Karen H.Two Harbors
Asked for a new AC quote. They came out, did real measurements, told me my existing furnace had four good years left and there was no reason to replace it just because I was adding cooling. Saved me $4,000 on a hard sell I would have walked into.

Tuned up our furnace and humidifier in October. Tech walked me through everything he saw and made one small recommendation (a new flame sensor) that he had on the truck and installed in 10 minutes. Painless and professional.
