"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"Sam Marsala was very good at diagnosing my furnace trouble, the fix was simple to my relief. My water heater was on its last legs. Sam diagnosed the trouble and we had Sam install a new Raheem water heater. He was very quick to respond to my needs and explained very clearly the trouble found. Installation was really done neatly and he left the work area very clean. I am more then satisfied with the work, product and technician. Well done."

"Robert has been here twice before, so we knew what to expect: pleasant, professional, and efficient. We had a fill valve problem and replaced the fill valve with an identical piece. However, upon replacement, the water line was leaking, and the shutoff was not entirely stopping the water from filling. Robert reseated the work I had done, explained what my problem was - missing seal, and replaced the shutoff. No troubles since."

"Andrew and team were out very quickly and worked in a storm to get our sewer lines unclogged so we did not take on more water. We had another big rain storm the following week with no more water backing up into the basement!"
