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.

UPDATE ***************************************The company came out to correct issues from previous install. Today's service was great and I can't complain. I still can't give a 5 star review until I know the issue is fixed. By tonight we will know. Once I hear from the manager and he/she validates the repair finally done right and the drywall access has been fixed them I'll update my rating as fully satisfied. Everything below this update is old review which will also be pulled once 100% complete
***************************************
This review is not on the tech. Its on after the sale and install follow up.
D&H knows all the issues we had prior to buying a new unit and they made that right. They also know about the defective product and made that right. But my complaint is what happened after the install.
The thermostat was loose and not installed securly, even the tech moved it back in place and didnt say or do anything about it. I had to call and get someone back out to secure it.
After second system was installed and finally working, before tech left he said someone would be in contact to fix the damaged drywall where the return air was put in. Not even an appoligy. One week later no call. I call D&H and im told it will be sent to a third party and they will contact me. 4 days later still no call so i call back and ask for phone number to contractor and im told they dont have it but she will send my info to the scheduler and they will contact me and also have contractor contact me. So now were on today almost 24 hours later and still no call.
So D&H im not happy with service after the sale. You got my $18,000 dollars and im a closed book.
By the was they also took out the old gas furnance and shut gas valve off but did not cap the line. This im told is a must.
Its sad but im having to hire someone to come and repair the wall and install the return air vent properly(only one of 4 screws are holding it and there is nothing keeping the unit from pulling air, dust and what ever from the wall cavities. There is a top board in attic but air is still being pulled from around cracks and holes and open space)the area where the air handler attaches to the duct work is loosing more air then what comes out of the registers. High power line is not secure and they used part of the old systems condensation tube to run the new line, the old tube is colapsed. This is just not quality work. Ive asked for someone to come out and see this with no responce. Very disapointed, that i have to hire another hvac company to come clean up their work
UPDATE
Owner responded with apoligy and said someone would call me this evening. That was 40 minutea ago and its 5:35 in the evening.
I left a message on their chat box not to bother, i cant afford to take more time off of work. Ive already secured a contractor to fix my walls and cap the gas. Ill find someone else to fix the leaking air and condensation tube

Had service after hours on Sunday. Luis came out found and took care of the issue right away.

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.
