I called Northern Air Systems after a previous HVAC worker wouldn't come back to finish the job he started on my boiler system. My boiler was working, but after he left I only had half the heat registers working in my house because they failed to bleed the air out of the system after the work they did. These guys had someone out to my house within 4 hrs to get my boiler heater back up and running. Joe the technician was great to work with and communicated with me on how to do some maintenance on my own in the future if I need to bleed my system in the future. Fantastic company that put me and my need, after having been treated so poorly from a previous company, a top priority. Thank you , Thank you!

Recently had Central A/C installed. They were very polite, professional, and did an excellent job. They pay attention to details. Their prices are fair and they do exactly what they say they will. What more could you ask for. Would use them again and recommend them to others. Thanks to the entire staff.

Called on Memorial Day with my air not working, knee surgery the next day in 90 degree heat outside and now 85 degrees inside, NORTHERN jumped into action to schedule me the next day, ordered a part and to schedule a return visit. So very impressed with this company. From Kate in the office and the tech, Eric that helped get my air conditioning up and running truly an exceptional staff. Eric explained everything thoroughly, very professional and courteous. Can not say enough about this company!!
