Get matched with top tankless water heater repair pros in Harrison, NY

"Discovered our 6 yo gas water heater developed a leak. Decided to call on these guys as they provide the annual maintenance for our A/C and furnace. Called early AM and they were able to have a service technician on-site within 3 hours. After inspecting the tank and finding the source, the technician proposed the replacement options. Although most seem costly, the technician did a great job of explaining the work involved and how much time it would take. After doing some research, I went with these guys....and everything went to plan. Was able to schedule an appointment that worked for our schedule. The same technician came back out with another colleague. The entire job took about 5 hours. They answered all my questions. And they worked very neat. Yeah, they weren't the 'cheapest.' But, they corrected some previous issues, worked efficiently and completed the job correctly and in relatively quick time. They new exactly what to do and how to do it. Very good experience. Thanks, SILA team!"

"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!"
