"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."

"I had an issue with my stream boiler last Saturday. Did a google search and called multiple companies except Lighthouse (also part of Premier HVAC) picked up the phone right away and the tech Slava (unsure if I spelled his name correctly) showed up an hour after my call. He was very knowledgeable. He first did a thorough inspection on my streamer boiler (I thought mine was called furnace but he corrected me and luckily Lighthouse also repair stream boiler), then giving options (replace the water feeder and side glass or the whole stream boiler since mine was already past 30years and it may not last long). Due to budget issue, after discussed with my family, we chose for now just changed the parts. Slava has no problem with that and I got lucky that he was about to arrange time to have the work done the same day. Slava is also very patient and professional. As he learned that I am new to streamer boiler, while he was doing his work, at the same time, he was giving “a lecture “ in terms of names, functions of each parts and the concept of how the stream boiler works and how to maintain it properly. I gotta be honest that I don’t recall all the he mentioned but at least now I have a concept. In terms of the price, I can’t say that it’s cheap but you pay for the quality of service that you get. Slava literally taking his time and spent about 4 hours to repair. Highly recommend."

"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."

"My old hot water heater died and I needed a replacement fast. From the time I contacted them to install it took 5 days and that's including them coming out to give me a quote first. They were fast, professional, friendly, knowledgeable and the price was very competitive. The installers were knowledgeable and checked everything after install. I went from a tank to tankless unit and it has been seamless, would definitely use them again and highly recommend them!"
