About D&H Air Conditioning, Heating & Plumbing

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.

I needed to replace a water softener ( I provided the new unit) the job was pretty much removing the old unit and reconnecting the new one. The plumber was was efficient and courteous. He even reset the controller box and tested the water for hardness. I would highly recommend D&H plumbing department. I purchased my AC unit a few years ago and their service was also very good. Glad to see them expanding into plumbing.

I had a great experience with Tim, my AC technician. He was extremely professional, knowledgeable, and clearly very experienced. Tim took the time to explain what was going on, answered all of my questions, and provided helpful information without making me feel pressured or confused.

What really stood out was his positive attitude and willingness to help. It’s clear that Tim takes pride in his work and genuinely cares—he quickly diagnosed the issue with the unit and fixed it quickly. I highly recommend Tim to anyone looking for an honest, experienced, and professional AC technician!

Absolutely excellent service! We had a serious water main break in our front yard. We immediately called D&H and Gilbert arrived within an hour. He quickly diagnosed the issue and provided 2 solutions. The problem was then solved 24 hours later. Everything procedure was explained clearly, Gilbert & Mark were courteous, professional & expedient. We're beyond satisfied with D&H.
