"In late June of 2023, Neo and his apprentice replaced our water heater. Neo did charge slightly more than Google reported as the average price in our geographic area. However, "you get what you pay for." Neo was diligent, friendly, efficient, and knowledgeable. Neo responded promptly to all telephone calls and text messages. There was no drama with Neo. Neo was a consummate professional. We would definitely recommend S&S Piping and Heat. When we experienced a runaway faucet and a broken shut-off valve in the spring of 2024, Neo was quick to respond. Our over-engineered faucet required more than the replacement of a simple washer. In a professional manner, Neo repaired the faucet, replaced the valve, and corrected a related water-pressure problem. As usual, Neo offered good, solid communications. Yet again, we would definitely recommend S&S Piping and Heat."

"I ca;;ed pm a Friday morning, late morning, and I was assured that the work would be completed that day. He asked the necessary questions, picked up the water heater, installed it in a hassle-free manner, and hauled away the old tank. The price was fair and affordable."

"Morris Heating and AC provided service that should serve as a model for all other service providers. They were consistently professional, efficient and response, ultimately installed a system at a very good price and did so urgently as we were entertaining guests from out of town. From the front office (Heather and Kaitlin) to the service manager (Greg) to the individuals who actually did the work at the house - beginning with Julin, then Blaise and finally Christos who actually installed the system, I interacted with very pleasant and effective people."

"I am a new homeowner that was looking to complete a few projects around my new home but wasn't sure where to get started. I recently had a heat pump installed and integrated to my existing oil furnace by Blue Bear. The Blue Bear project manager helped explained the difference between fully electric heat pump systems and dual fuel heat pump systems, both options were Mass Save eligible so I would be able to benefit from an instant rebates and not have the hassle of filing rebate applications! Blue Bear took care of it all! We chose a dual fuel heat pump system and the installation looks great! I look forward to saving on oil consumption this fall/winter! Everything went well with our HVAC install and now Blue Bear will be installing a whole home well water water filtration system in my home! We look forward to getting rid of the water staining in our toilets and showers! The Blue Care maintenance plan was a no brainer to sign up for! I highly recommend Blue Bear! 5 out of 5!"
