Dan and Derek were excellent - great communicators and honest technicians. They helped our grandmother get her AC up and running and did a complete and thorough diagnostic. Would gladly have them come back for any future maintenance or installations! Very reasonable pricing as well.

From start to finish, the owners delivered on exceptional communication, fair pricing, and high quality workmanship. During some of the hottest weeks of the year when HVAC related repairs are in high demand, D.A.D HVAC found time to help me. I needed a natural gas line, PVC venting, and ductwork temporarily removed to allow for a critical joist repair. Dan made three separate service calls at my property within the week; one to diagnose, one for disassembly and another for reassembly. Dan and Derek were responsive, reliable, and clearly took pride in doing the job right. They didn’t upsell extra services, and were upfront about costs. I’m very satisfied and I’m glad I chose D.A.D. HVAC instead of one of the large corporate HVAC service companies. The personalized service, attention to detail, and customer care made all the difference. Thank you, Dan and Derek, for going above and beyond. Highly recommended!

We initially had another company come by and diagnose an issue with our furnace over the holidays but they ended up misdiagnosising the issues and recommended a full replacement which felt like we were being gouged. After that experience, I was recommended Dan through a friend and it was a night and day difference in experience. He came on boxing day and was able to diagnose and fix the issue within 2 hours. He is very knowledgeable and explained what happened, even went above and beyond with his diagnosis and made some really great recommendations to optimize our furnace set up. Dan will be my go to for all H.V.A.C needs, he knows his stuff and is really looking to solve your problems not just charging you the most. I would highly recommend if you are looking for a trust worthy and knowligable H.V.A. company.

Dan made things right with our non-functioning humidifier and took the time to explain not only about the service he performed, but how to better use the equipment.

Dan and Derek are very competent and efficient. It took Dan few minutes to diagnose the issue, when other technicians were just guessing. Before you contact anyone else, I recommend that you contact DAD.
