"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."

"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."

"SILA called to offer their annual heating inspection services given that I was a prior customer. The gentlemen they sent, Ivan, was very knowledgeable and thorough. He went over and above, and spent a lot of time explaining the parts of my boiler to me and likely failure points, gave some recommendations on my aging indirect water tank, and even answered a few questions I had regarding thermostat wiring. He was very patient, and left everything clean and exactly the same was as he had found it. He wore a mask, covered his shoes, and was very respectful. I've used SILA for my annual inspection every year the past five or so years."

"I spoke to Lou Schede about a horrible sound coming from my washing machine when the hot water was on. I'd already had an appliance repair man in, who suggested that I contact a plumber. I was on and off the phone with Lou all day, sending pics of the valves etc and communicating with the super in my building. Eventually it was determined that the issue was not with the plumbing overall, but was limited to a faulty valve. I believe I have found in Lou Schede a true master in the service industry. Someone who is willing to put the time in to figure out the source of a problem, without any sort of upfront payment. Because of Lou's integrity and the level of verbal service provided, as well as his willingness to speak with me patiently and clearly, this will be my first call in the future when I am ready to do the inevitable renovation of this condo."

"Called because heating system would not start up.  The company came a short time later and found out the problem was a simple fix which involved adjusting the angle of a waterline.  I highly recommend because the service was great and I had a very good overall vibe throughout the whole process. <br />"
