"They care! They stopped by to address a hot water heater on the blink but the weather was brutally cold and Mikey saw me working on the boiler… After addressing a plan to convert to tankless, he helped me make the decision to switch to a tankless combi solution. Very happy how the team took the time to complete the job timely. I will use them for other projects for sure"

"Great! The workers are very professional and punctual. They installed a tankless water heater. They cleaned everything up when they were done and then explained how it worked and how to maintain it throughout the years so it would work better. I highly recommend this company."

"It's always difficult to get someone who is willing to come by to fix those little annoying problems you have, but not Tom. I had 1 leaky faucet and 1 frozen faucet(due to hard water). Tom came explained what needed to be done and I hired him to fix it. Very pleasant to work with. Also cleaned up after all the work was done. I have his card now and will not have to stress when I need a good plumber in the future. No job is too small for Tom!! He will be back in New Year to install a tankless water heater."

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"I had a great experience with Premier HVAC replacing my old and leaking water heater. I was impressed that they were able to respond quickly and start working on the same day as my call, especially given the severely cold weather and other plumbers being busy replacing freezing pipes. The plumber was able to work with my very tight kitchen space and narrow hallways, and without having to remove the countertop in my kitchen. I am satisfied with the installation and would definitely consider Premier HVAC for future plumbing needs."

"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."
