"We would be happy to recommend the services of Integrity 3 to anyone we know; both commercial or residential. We have a large property with a lot of HVAC units. Any time we've called, day or night, Integrity 3 responds promptly, checks in with us, informs us of the work that needs to be done and then repairs it correctly. They really fix the problem. It's not just a temporary fix. We appreciate their work ethic, professionalism and willingness to work hard for our business. Their name says it all and we are looking forward to a long professional working relationship with their company!"

"Trustworthy and knowledgeable comes to mind when I think abut Nolan Harkness. He installed our new cooling system and the yearly savings on our electric bill has been evident. His recommendation was one I'm glad I followed.

Since that installation we have needed one service maintenance - nothing more than an air filter, as it turned out - and he scheduled us immediately. We had summer house guests and both my wife and I were relieved to receive such prompt service. I highly recommend Integrity 3!"

"Nolan worked on our unit when the weather turned hot and it wasn't working correctly. He diagnosed the problem, fixed it and serviced the unit. He was knowledgeable, professional, efficient and the price was more than fair. Integrity 3 and Nolan is who we use and recommend. Go Integrity 3!"
