Report
We've used Northern Air Systems for several years now for HVAC maintenance and have been very happy with the service they provide. We decided to replace our furnace and AC this year. We had a competitor come out and give us a quote and the saleperson was mostly interested in selling a system and didn't take any time to look at the ducts, etc. Bob from Northern Air came out to give us a bid and took measurements and made drawings before trying to sell anything.
He explained everything and answered all my questions, and even made some recommendations for more efficient ductwork at a later time, if we wanted. The installers of the unit arrived on time and worked until the unit was installed. They also answered questions we asked as they were installing the furnace and AC. Bob has been very responsive to questions I had about rebates. The installed thermostat has lots of features that I've never worked with before and Bob has arranged a time to come out again and go over all the bells and whistles.

We've been having Northern Air Systems taking care of our HVAC system for many years, and I have to tell you they are GREAT! No matter which rep Kate (who herself is proficient, professional and really nice to boot) schedules to come out for service, the guys are all knowledgeable, efficient, timely and, well, as I said GREAT! Try them; you'll like -- no, you'll LOVE them! Jill

We have been using Northern Air for almost three decades. No matter the service- routine yearly maintenance to installing new A/C or heating system, Northern Air does great work. They honor their commitments and are always professional. We recently needed an emergency repair and Kate in the office and Gary the technician made it happen. This was a great relief to me and my family. We give Northern our highest recommendation.
