"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"I had A&M service my On Demand hot water heater. He did a great job. I decided to have additional work done. I have an older home and decided to have some old valves and pipes replaced. I would definitely recommend A&M"

"This was the second time using South Shore Plumbing & Heating they installed a tankless water heater for me in March. 2020 and today Nick located and fixed a pin hole pipe leak under my house cement slab. From the time Nick started to make his first cut in my Sheetrock he used a level to make sure he was cutting a straight line ( thatâ s a professional who take pride in his work) when he drilled to open up my slab he made a small hole that was right where the pipe leak was. Cut out the bad pipe and installed new section of pipe no leaks and Nick re- cemented the hole closed and clean up all the debris. Anyone who needs excellent plumbing or heating call South Shore Plumbing and Heating ."

"We refer friends and family to Clearway without hesitation; these guys are the best. We first found Clearway on Angie’s List about 6 years ago. Our home is starting to show it’s age and we’ve been trying to update things proactively, so we decided to take advantage of a coupon they had to replace an outdoor spigot. Two outdoor spigots, one leaky faucet, two toilet replacements, one slab leak repair and, most recently, an update of our hot water heater to an on demand system and we wouldn’t dream of using anyone else. Their work and customer service are second to none."

"Anthony and his crew did a great job in providing and installing the exact system that I had requested.  
They were thorough, professional and very neat and very easy to work with.  The installation was completed in one day.
The pricing was more than fair.  I couldn't be happier with the new A/C system.  I highly recommend APV to anyone in need of a new central A/C system.

"Heater was making a knocking sound and of course it was the holiday season. Braido came out right away and found a fan part needed replacement. The parts vendor was closed but they came out the next available day and had everything running smooth."
