"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."

"Steve was absolutely amazing to work with! Needed to replace my water heater and messaged him late Wednesday night, he got back with me early Thursday morning with the quote and came out that morning at 9:15 to replace the water heater. We got a great water heater, easy installation and the work was done very well. Steve is very knowledgeable and has such a great personality! You will NOT go wrong with hiring Steve! Thanks again for all your help, Steve."

"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show. They were extremely friendly over the phone. I called at approx 8AM and said they'd be able to come out by 11AM. They called at about 9:30 to say someone was available to come out now and I said that was perfect. They arrived at 10AM.
Jason was the plumber who arrived and he was very very friendly and professional. I told him the problem and we discussed pricing up front. I had a coupon which he said they would definitely honor. He immediately got to work. He wore footies over his shoes while in the house. He worked diligently and answered all of my questions. After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.
A very pleasant and hassle free experience. I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.
The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."
