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.

Arizona summer is just brutal, I was having issues with my AC again. I hear the unit running but the house is not getting cold. I called D&H 24/7 service. They were able to fit me in the same day (Saturday). Giovanni did the inspection, he took photos and run diagnostics so he can explain it better. This was a same day maintenance service so hoping not to have a lot of issues. The problem was the capacitor (about 3 years old)that needs to be replaced. The issue was resolved and AC is working properly especially with 105 degrees heat. I definitely recommend D&H service. Giovanni did a phenomenal job, absolutely satisfied and I highly recommend D&H.
I also wanted to extend my thanks for Giovanni for bringing up a gas smell and having us reach out to Southwest Gas to do a courtesy check. They eventually came out and fix the leak. His attention to detail and priority to safety is above and beyond. Thanks you Sir.

I know I have posted several times about this business, but when you have locally owned company that provides phenomenal service you need to put it out there. Had a simple issue I could have probably fixed, but called a technician out anyways. Ethan showed up and took the time to explain what to do next time as it was an easy fix. However the way he explained what happened was fantastic. D&H has always sent employees that are respectful and treat customers to where they don't feel dumb for asking questions. Again. All around great service from dispatch to Ethan taking of of the customer on his end. Can't recommend enough.

Our central air went out last night. D&H was here before 10 am and had the unit running full blast by 10:30. Kudos to Isaiah who was up on the roof but also to the front office, who we found to be very cordial.
