"Robert Johnson was so helpful in discussing the h/w heater installing and the venting requirements. His price was so much better than others companies in the area. His crew for the actual install was as also great! Kevin, the crew leader, explained how everything works and the cleanup was perfect!"

"We have had several Sila visits in recent months - all exceptional. VISIT 1: We had old pipes and valves that limited our dishwasher, so we had that replaced. While there, the Sila agent suggested we replace some of the attached lines and managed to streamline our hookups by removing some of the unneeded valves and connections no longer needed. VISIT 2: We similarly had a great visit and instal from David, who did a very beautiful install on our new water heater. He removed the broken unit, improved the connection design, put in improved valves and labelled each with a tag, then tagged other connections through the basement."

"This was a home improvement project that exceeded our expectations in every way. The experience and expertise of the NETR team was clear from the start. The interior design and structure of our house presented some uncommon challenges for laying and running the conduit through the basement and up to the 2nd floor. We are very satisfied with the results, both inside and outside. The team was able to match the color of our siding. The location of the external compressor and the three conduits on the outside walls fit well into the exterior of our home. The A/C units are quiet and the air filtration and cooling performance are great. Adam and Jim were the install team, they were excellent, professional and did a nice job explaining how to operate and maintain this Mitsubishi system.

"Our water heater went right when my husband was laid off. Joe worked with us to stay in our budget. Will hire again for future projects"

"We can’t say enough about Matt. He was very responsive to our need. He was out the very next day and was at our home at the time he said he would be there. (That is unheard of these days). Matt was very professional and thorough. There was no surprises with job. Matt and Chris were very efficient with the installation of the hot water tank. We would readily use Ferris Plumbing and heating for any future needs."

"?I couldn't be happier with my new water heater installation. The team was professional, punctual, and incredibly efficient. They took the time to explain the new unit's features and ensured the workspace was spotless before leaving. ?It?s a relief to have hot water back with zero stress. If you need a reliable install, I highly recommend Expedition!"

"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs. They did have an opening for next day installation which would have been fantastic but I couldn't justify the additional $2400."

"Addario's Services did a great job installing a new high efficiency combo boiler in our home. After I requested an estimate, I got a quick call from the office to schedule a time for one of their comfort advisors to come out to our home. Sam, my comfort advisor was very knowledgeable, and I appreciated his low pressure presentation. Once the work was booked, because our installation was complex, Joe came out and came up with a plan to vent the exhaust on the side of my house to minimize the number of pipes on the front of my house. The installation went very well, and they installed a temporary water heater so we were only without hot water for less than a day. For the day we were without heat, they brought in plenty of space heaters to make us comfortable for that night. When the installation was complete, the installation technicians took lots of time to explain the operation of the new system, and to answer any questions I had. The system is working great and there have b"
