J. W.

Purchased a new HVAC last year and have had wonderful service since installation. They had the best price and on American Standard equipment. Very attentive to details, very honest and fair. Continue to use them and refer to family and friends.

I have worked with Nathan for a few years now. He has always been fair, explains everything, and gives you options. He has never tried to oversell his services and has been honest about issues with the systems I’ve had (have moved a couple of times). He’s helped to patch up old systems until I was ready to buy a new one then helped me select the right systems for me and my household. I appreciate him, his knowledge, and I have recommended him to anyone I know.

Denny O.

I had maintenance performed on two units and found OT to be flexible with the scheduling, timely in arrival and extremely knowledgeable. Nathan provided the service and was very thorough. Payment process was a breeze and the price charged was as he had quoted me. He was very professional and wore shoe coverings when coming into our home. Nathan was very respectful and I wouldn’t hesitate to use OT again.

The most exceptional air conditioning experience I have ever had. When a fire broke out outside our home, he responded promptly and collaborated with us on our schedule, accommodating our inability to reside in our home while repairs were underway. I highly recommend Nathan to anyone seeking exceptional air conditioning services.
