Whenever I get service from Northern Air, I keep getting reminded why I continue going back to them. They are clean, professional, and courteous. Our technician Eric was great. I asked if could wear a mask given our unvaccinated kids and he didn't hesitate to put it on. We will keep going back to them for any future needs. Service: HVAC system maintenance
I highly recommend Northern Air Systems! I phoned them at 10 am on the morning of July 4th. Scott was at my home by 10:30 am and had my AC up and running again by 11 am. I very much appreciated Scott’s professionalism and honesty. I will definitely be calling on them again! Thank you again Scott! Service: HVAC system repair
