Our History

Tucson’s Trusted home service technicians

Founded in January 1959, D&H Air Conditioning began as a family business when WWII veteran and experienced journeyman sheet metal mechanic Arthur Duhamel moved from New York City to Tucson. Partnering with Harry Hawk, they combined their initials to form D&H.

With a reputation for honesty and a commitment to quality, D&H AC began to grow quickly. As Tucson developed rapidly in the 60s, D&H expanded into other areas such as upgrading of existing A/C equipment and ductwork, service & repair, and commercial HVAC work.

Tim was very good and professional. He solved the problem we were having with our air conditioner. He was the 3rd serviceman in the last 5 days

Tim Caho with D&H did a great job repairing my heat pump. I appreciated his honest advice about the risk associated with repairing an old unit like mine. I decided to assume the risk and go ahead with the repair. Tim’s years of experience were evident as I watched him replace the faulty parts. I tried not to bother him too much as he worked, but he patiently answered all my questions while navigating the tangle of wires and components. It was a pleasure chatting with Tim. I feel lucky they sent me him.

I had a great experience with Tim from D&H Air Conditioning. He was extremely friendly, professional, and knowledgeable. What I appreciated most was that he took the time to explain what was going on with my HVAC system and helped me better understand how everything works instead of just coming in, doing the job, and leaving.

Tim answered my questions, explained things in a way that was easy to understand, and made sure I knew what to look out for going forward. You can tell he really knows his stuff and cares about providing good service.

Overall, I was very impressed with the experience. Great customer service from start to finish. I would definitely recommend D&H Air Conditioning, and a big thank you to Tim for taking such good care of us!

This an honest and reliable family-own company. I had an AC emergency (four animals) and Pedro was here within minutes. He carefully assessed the problem, quoted a reasonable price (thermostadt), and executed the work promptly. Soon after, we discovered another problem (we don't do adequate annual maintenance, which Pedro educated us on) with our AC compressor this time. Pedro returned (at no house call charge this time), assessed the new problem, again quoted a reasonable price, and executed the job promptly and efficiently (taking only as much as he needed; no dilly-dallying). I had full AC service by end of day. I'll never use anyone else. Thank you Pedro! You're a life-saver!! 🙂
