Adam and his team were very professional and friendly. Once the water heater was installed he walked me through the installation process, showed me how it functions and gave tips for maintenance etc.

From the initial, timely estimate to the install everyone at Dave's was very responsive. The install was seamless and the cleanup was excellent. Even though I know next to nothing about HVAC systems, Adam never let me feel like my questions were silly. I would highly recommend this company for all of your HVAC needs.

Dave’s did a great job replacing my old gas hot water heater! Professional and clean work with a choice of Bradford White and AO Smith 75 gallon in stock. Excellent planning visit, quoting and contracting process. Even a follow up to make sure we are happy! Thank you Dave’s!

Adam did an excellent job replacing my water heater. He was professional, courteous, and respectful of my home throughout the entire installation. He took care to keep everything clean and made sure there was no mess left behind.
I also really appreciated that he kept me updated throughout the process and explained what he was doing along the way. Once the installation was complete, his team walked me through everything that had been done and made sure I understood the new system before he left.
Overall, it was a great experience. Adam was knowledgeable, professional, and easy to work with\. I would definitely recommend him.
