They where honest they cane fixed it and then when we had another problem they came back and re fixed it for free they where affordable and reliable we have used them alot and everytime they have done nothing more than what was needed and even went out of there way a couple times too hook up a new thermometer that they gave us we didnt even ask them to do it but they knew the line in the old one was cut so they fixed it free of charge
Joe our technician was AWESOME. He located the problem and found other issues that were never done when the house was built 11yrs ago! We were both shocked. Kate the scheduler was very helpful as well. I would totally recommend Northern Air Systems to anyone and will continue to use them if problems arise in the future.
