HE CAME IN AND LOOKED IT OVER AND GOT IT ORDERED RIGHT AWAY AND PUT IT IN TWO DAYS LATER. I HAVE NEVER DEALT WITH ANYONE MORE HONEST AND ACCOMMODATING, , I WOULD RECOMMEND HIM IN A HEART BEAT. THE TWO GUYS THAT CAME OVER AND INSTALLED THE UNIT WERE GREAT AND HE CAME A COUPLE HOURS LATER AND FINISHED HOOKING IT UP.

Showed up on time and was able to get the issue with my furnace figured out very quickly. The techs that came out were also great at answering my questions and explaining stuff to me.

Northern Integrity has done a top notch professional job. I would advise anyone who needs this type of work done to contact them. The work was 5 star quality and everything worked perfect the first time. I have the best working furnace/duct work/registers that are possible. I thank them all so much and hope others will call them immediately for the best job ever.

Our furnace was making a funny noise and we call Mike's company to check it out. He came over to our house and he found out that we need to fix or replace the furnace. Mike ended up replacing our furnace. Mike did a great job and at a reasonable price. He took time to explain what was wrong with the old furnace and gave us choices about what kind of new furnace. We will have Mike do all our heating and cooling work.
