"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."

"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."

"Two very courteous gentlemen showed for this job with only the tools they needed. I’m glad they were not trying to oversell what they do or make more of the job and string sell anything. Just came in looked at the thing and laid out their protective stuff and went to work. About the easiest service call I’ve had in a long time. Now I can heat living room instantly from fireplace."

"Outstanding service, start to finish. Professional, courteous, constant communication. Isha from the home office was in constant contact - phone, two email confirmations, and texts. She called to ask if the service could start a bit earlier, which was fine with me. Alex arrived promptly, put on shoe booties before entering the house (not necessary here but a nice touch). Alex was outstanding. Young fellow with many years experience, and it showed. He explained each part of the task as he went through it, and answered my many questions related to other potential work I brought up. Getting the anodes out of the water heaters - first time replaced - was a bear. He explained he had to get another socket wrench to loosen the anodes - the ones he had did not fit properly. No charge for that time, which though I expected, has not always been the case in my past experiences. Anodes were locked in tight, and took a while to loosen. Doing one water heater at a time, they finally came out, encased in calcium deposit. He then screwed in the replacement anodes and locked them in. Alex completed all the work, put everything back together including the fans on top of the units, tested, and re-tested. Continuing to explain each step. He took pictures of the work for the invoice, ran me through the details again. Everything done on his tablet computer; I received an immediate email receipt. Excellent work with knowledge behind it. I have an external faucet which needs repair, and may be looking for a whole-house water softener. When time comes to replace the water heaters, Advanced Pro will be at top of my list."
