What Your Neighbors Are Saying About Us

Northstar Services was able to get someone out to fix my furnace within 24 hours - at this time of year, that's really impressive! Ron was professional and friendly and had everything running smoothly again very quickly, and cleaned my furnace before he left. Definitely would recommend!

We have worked with NorthStar for a few years after having a furnace and two mini splits installed. Their customer service is excellent. Staff are always friendly and knowledgeable. Ron came to service our units last week. He answered all our questions and did a great job. We have and will continue to recommend NorthStar Plumbing and Heating.

Very quick to schedule a furnace inspection with the technicians. Charlie was so helpful in educating me while discussing options to replace our furnace and AC. Michelle at the office was able to promptly answer all of my payment and administrative questions. Finally, Andy and Sam were excellent during the installation process. I will be recommending North Star to all of my home-owning friends!

Luke addressed a lack of heat in the home and thoroughly explained the dual fuel system, including scheduled power interruptions with MN Power. He assessed BTU capacity vs output capacity and offered recommendations. He is an excellent educator with exemplary customer service and friendliness.
