“Stuart was very nice and personable answered all my questions and explain things very well.“

“Northland Comfort responded quickly to our service request. The technician, Trevor, was courteous and had the issue diagnosed and the repair completed in a timely manner. We will definitely use your services in the future and will recommend you to others!“

“MMT Heating and Cooling is our go-to for all mini split and boiler issues. They installed our mini splits on short notice in spring of 2021. They were super responsive and really made us feel like our home and needs were a priority for them. We got quotes from two other companies for our AC but went with MMT because they were the most responsive and professional in their communications and gave us a lot of confidence that they'd do the job in the most cost-effective and efficient way possible. We've been very pleased with the outcome.They also replaced our boiler and a thermostat. The number one thing I appreciated about their work on our boiler (besides being nice and warm again) is that they were SUPER clean! When they were done for the day, there wasn't a trace of the enormous project they had undertaken in the basement. That was HUGE for us because we have a toddler who will find anything that she's not supposed to eat, including trash and debris, and then she'll try to eat it.These guys are phenomenal. We really appreciate and respect their work and would def recommend!Services: A/C system maintenance“

“Just had my gas furnace and hot water heater replaced by Carlson Duluth. Could not be happier. A young fellow named Jake ramrodded the job. Very pleasant and conscientious. He did a fabulous job. I highly recommend this business.“

“Guthrie Plumbing and Heating has been an absolute pleasure to work with. From booking the appointment to the service provided this company is top notch and goes above and beyond for customers. We have older pipes in our home and Dale took the time to discuss our options with a leak we had and also helped us trouble shoot some freezing pipe issues we had during the last cold spell.
They were on time, polite, professional and cleaned up very thoroughly. I appreciate the great communication throughout. We got more than our money's worth with this company. Thank you, Guthrie Plumbing and Heating!!“

“Jeff helped me replace a hot water heater with ease and also walked me through troubleshooting my furnace after an amateur homeowner repair on my end. He took the time to explain everything step by step, accurately diagnosed the issue, and helped me get the exact part I needed—on the day before Christmas, no less.

Extremely knowledgeable, extremely professional, and incredibly helpful. I would absolutely hire him again in a heartbeat for anything HVAC-related and highly recommend him to anyone needing reliable service.“

“Great service! From first phone call (handled very professionally) to project complete and follow through they did an outstanding job. I highly recommend these folks!“

“I had been having water pressure and water heater problems, in my brand new home, for 4 years. The company who built my house had been back multiple times trying different things, finally told me “it’s normal for a new home for a few years to have problems like this.” Finally after multiple people told me to try a different company I listened. I called North Star who sent Ron, same day, to my house who located, and fixed(!) the problem within 45 minutes.
He has since been to my house two additional times for regular maintenance. He is quick, efficient, clean and very patient with my questions making sure to explain what he’s doing and why. I feel safe with him in my home. North Star will be my first call from now on!“

“I had an air exchanger that needed replaced due to unavailable parts. Bill changed the unit and retrofitted the wiring so that all works as it should. He ws great at keeping me informed and checking on progress.“

“Prompt response. Fair prices. Quality work. Would recommend. Surprising I didn’t take any photos.“

“Efficient, timely service.
Toilet part replacement and discussion of kitchen sink parts replacement.
Cody gave us excellent service“
