Get matched with top water heater installers and replacers in O Fallon, MO

"Jason and Allen were great to work with. They had to wrestle with our 30 year old water heater and replace it with a nice new one. They arrived on time in a snow storm and finished hours ahead my expected time frame. I was waiting to hear a list of excuses and expensive problems. However everything was positive and informative. The guys were friendly and prepared. The cost estimate was exactly what the bill was. Plus I learned more about my house which was a great bonus."

"Did a great job replacing my water heater and was about 30% cheaper than the other bids I got."

"Steve arrived on time, quickly diagnosed the problem with the water heater, gave me options to fix/replace without trying to steer me to one option or the other, and answered my questions. I opted for replacement and he got the appointment set up for the next day so we wouldn't be without hot water any longer than necessary."

"Remove electric water heater and install a new high efficiency gas water heater."

"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!"
