Get matched with top water heater installers and replacers in Greenwich, CT

"When we realized our water heater was leaking, Aldo's was fast both to respond to the inquiry and to get us a replacement; within 36 hours, we were back to having hot water with a new tankless setup. Pricing was within the range we expected and the team was very communicative; I'd hire Aldo's plumbing again!"

"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"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."

"Wilson was extremely professional. He came to my condo to make repairs to two toilets. Wilson did a great job. He explained what needed repair, showed me the parts he replaced and cleaned up after himself. I would definitely hire him again."

"I was looking for permanent HVAC company for my home in Long Island, I usually do a yearly maintenance for my units and I wasn’t happy with my previous contractors"

"Matt was great. Very responsive, professional and efficient. Installed a new hot water heater for us is no time. And a very fair price!"

"Fast service replaced water heater next day after my call will use again!"

"Used them several times because the service has been great and posted a positive review but felt the need to add an update. I got a second quote for replacing old water valves with PSEG and the difference was in the thousands so ended up going with them. Despite telling AP I would go elsewhere, they kept calling me to pay for the estimate they gave me to complete the service and I got confused. A little turned off by that in addition to the price."

"Water heater broke Friday, had new one installed by Monday afternoon."
