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.

This morning Isaiah came for our heating system annual servicing. He called before coming and introduced himself on arrival. After showing him the location of the equipment he began his inspection. Isaiah took amperage readings on the blower motor and took pictures of the blower wheel for his report. Finding the system ready for the heating season he made his recommendations for maintenance services. We were very pleased with Isaiah and his service.

I called about a problem and the front desk scheduled me right away. The technician Zach was amazing, he was very knowledgeable, courteous, and professional. He listened to understand what was happening and he went right to work and quickly found the problem. He found a replacement part and then picked it up, installed and tested and things were working again. 5 stars to D&H and Zach for a great 'get it done' effort. Yes I would recommend them to friends and family .

Isaiah came out today for seasonal heating system checkup. While he was here he noticed that the surge protector needed to be replaced, and did so. The visit was prompt, courteous, and professional.

I had a plumbing issue. Daniel found the problem, checked multiple places where the problem could have been, and explained everything. He was so nice and friendly but also professional and polite. I can’t say enough nice things about him. When I need help with plumbing again, I will call D&H and request Daniel specifically.
