"I highered Bruce and his team, we're very happy with the service. They installed a couple new baseboard heaters to our existing unit to add more heat to a few rooms that's were cooler than we liked. We're very happy and much warmer. Bruce and his team were responsive and open to everything they were doing. Fast and efficient highly recommended!"

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"We decided not to go tankless but E&R did a great job installing a new 50 gal Rheem heater. Very quick and clean install. I will use them again in the future."

"Would hire them in the future if I have a problem. Arrived right on time. The plumber was courteous, did a great job. I can't say if the cost was great because I have no idea what the cost of installing a copper water line to a refrigerator costs. It was more then I thought it would be, but could be what other plumbers charge."

"The installation of the new boiler was excellent! They were quick and cleaned up everything when they were done. We were so impressed with their workmanship that we had them install â mini splitsâ for cooling. Extremely satisfied and happy with their work. I would highly recommend them."

"Great job by Total Mechanical Systems repairing/replacing old faucets on my tub/shower that would not stop the running water. Their tech, Joe, was friendly and professional. The problem is solved, I am very happy after this experience."
