"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"

"Called Home Depot at 6:03pm on Saturday 2/26/22. At 6:30pm Arctic Air Conditioning contacted me, had me take photos of my broken hot water heater. 15 minutes later, Katie from Arctic called me back with a more than fair price and worked her magic to get me an install for Sunday 2/27/22 at 2pm. Alex from Arctic arrived Sunday around 2pm and started the project. Elijah from Arctic arrived 45 minutes later and by 6pm ( 24 hours after my initial call) we had a new hot water heater up and running. Great experience, Alex and Elijah were professional, knowledgeable and courteous."

"When we were short on hot water and our furnace was on the way out, I contacted the The SaveGreen Project. They provided a list of contractors, and after numerous calls finally got through to a contractor that understood the program. Greg thoroughly explained the process, and even walked me the process, guiding us through from initial application process to final walkthrough. When Greg came out to assess our situation, he was very professional and extremely honest. He offers the best prices and uses high quality brands. His experience speaks for itself, he was the only contractor who told us we can install a tankless water heater. Additionally, he was able to help us with our failing furnace and provided one of the top systems for an extremely reasonable price. His staff is professional and clean. They put cover grip cloths to protect the floors, and were very careful when handling the equipment. Before installing the furnace and air purifier he performed a full duct cleaning. His staff was nothing short of excellent; they team showed up on time, worked efficiently, and the results speak for themselves. The level of communication speaks for itself, any questions or concerns we had Greg took the time to address and ensure we were completely satisfied. For anyone in need of plumbing, electrical work, or for any HVAC service, I highly recommend Greg and his team."

"If you’re looking for a top-notch plumber who tells it like it is and goes the extra mile, Anthony at Mr. Fix It is your go-to professional! I recently had three major plumbing concerns: fixing a toilet leak, creating a permanent dehumidifier solution for my basement, and replacing my water heater. Anthony handled all of these tasks with exceptional skill and dedication. One of the standout aspects of working with Anthony is his honesty. He’s straightforward and transparent about what needs to be done and how it will be achieved. This level of clarity is incredibly refreshing and reassuring. In addition to his expertise, the pricing was very fair and highly competitive. Compared to more corporate plumbing establishments, his rates are not only reasonable but also offer great value for the quality of work provided. Anthony also answered all my questions, including those related to electrical work, as he’s also an electrician. His broad knowledge base and willingness to share his expertise are truly impressive. Rob is incredibly responsive, even taking calls while on vacation, which highlights the efficiency of his operation. Anthony stayed late to ensure the job met my high standards and went above and beyond to ensure everything was perfect. If you need plumbing work, request Anthony at Mr. Fix It—he’s the best in the business. I wouldn’t hesitate to hire him again for any future needs. I highly recommended!"

"I was a little disappointed that the people that they sent out on an emergency basis for the $7000 project. We’re doing it for the first time. Had I known what I know now I would’ve demanded somebody come who had experience. Overall, they’ve done a good job and I’ve signed a service contract with them. One time in less than a year, they send somebody to service the continuous hot water heater and she falsely claimed I needed a condenser and charged me for it. I wish they would send people who knew what they were doing all the time."

Customers say: True professional

"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."
