"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."

"Mario and his assistant did a wonderful and fully clean and complete job upgrading my water heater to a larger size. He was fast with excellent communication and kept to his agreement to cart away the old one and install the size, brand and Model I wanted. I now enjoy a increase in hot water performance and have a new plumber in him for future repairs and plumbing related projects. I would highly recommend him and his professionalism to my friends and family. Joe"

"Mr. Miguel was professional and well informative and offered an affordable solution to the problems I was facing. He arrived on time and immediately went to purchase the supplies needed to make the repairs and replacements. I was in desperate need of caulking for the tub, shower head that was barely holding on, spout antiquated, toilets non efficient excess water usage, and even the bathroom faucet had an issue of rotting away. In demonstrating excellent customer service he asked was there any other issues and I showed him my kitchen faucet and immediately he saw the pipe was eroded and could burst. I highly recommend you to call if you are having any plumbing, hot water heater yes he even adjusted the temperature for me as it was extremely hot. 10/10 I give him and his helper. Would I use his service again, yes for sure already sent his number to my mom."

"Frank is fantastic. He is professional, prompt, and always there when you need help. What I appreciate most is that he takes a preventive approach to plumbing, catching potential issues early so you don?t end up with an ugly surprise later. That kind of care and professionalism gives real peace of mind. Highly recommend Frank for anyone looking for someone reliable, honest, and proactive."

"Anthony was very professional, and polite. He and his worker were tasked with removing and replacing 2 in the wall air conditioners that have been in the wall for over 30 years. The job was completed in 1 day and they left my home spotless. I would highly recommend New York Mechanical for all your air conditioning needs."
