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

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

"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."

"Cody was professional and the install was done in a timely manner"

"The technician was honest and said that the water heater is in good working condition not needing any repairs or replacement We were told the opposite by another company!!! They have indicated that it needs replacement!!"

"The installation technicians did an amazing job. I had them replace my toilet with one that was very difficult to install. It sat close to the wall with two inches available to insert your arm and reach in to install / tighten the bolt. I have no idea how the technician contorted his arm to install the bolts. The two technicians were very polite and professional. The communicated their arrival time and explained what they needed to achieve the impossible task. I would strongly recommend them and will be requesting their service in the future."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"
