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.

( 14Oct26) Tim just did a Family Plan check on the gas heater, found a small leak with his nose and a detector, fixed it. In and out in less than a 1/2 hour. He explained every step. I feel confident that we will have a working system during the cold months.

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.

New 5 -star review!
Tim Caho was out again for a new problem on a different heat pump unit this time. The outside condenser unit was being disabled due to a blocked condensation drain pipe. The air handler's emergency water pan was full and thankfully the float switch worked to disable the outside unit. Tim had to suck it out with a shop vac (two 5 gallon buckets worth! and not easy because the air handler is in the attic space). There was no drain pipe connected to the emergency pan (not up to code) and the P-trap on the main drain was made up with 90 degree bends in the PVC making it impossible to clean with a pipe brush. Tim installed a new drain pipe on the emergency pan and also replaced the P-trap with a clear plastic curved P-trap with serviceable ports so you can see any sediment build up and it can now be cleaned with a brush he provided. Another 5 star job by Tim!

I’m a bit late with my review! I was very happy with my service. I had my very old swamp cooler taken out and replaced with a brand new air conditioning system. Also a mini split in another area of my house. I wanted to mention all the techs who worked most diligently during the very hot August temperature. The four techs were: Jeremy, Kaleb, Kyle and Dominque. A week later I had my ducts cleaned by Luis and Jason, another job well done. Also a shout out to Patrick who had guided me on the conversion.
