Ferguson Plumbing Design is the Pepperell shop people call once something has already gone wrong. A June 2026 customer with an HVAC issue was squeezed in that week. In a May 2025 review, a customer whose kitchen sink drain unit had corraded away from the drainpipe texted a picture to Joe, the owner, and he responded that someone could be there in the morning. The work runs from plumbing into heating and cooling. A June 2026 customer had both HVAC lines flushed with hot water, completely clearing them of build up without using any chemicals, and the hot water tank flushed in the process. Another that month had two hot water tanks installed and wrote that the technician cleaned the area up better than he found it when he arrived. A third said Joe installed a whole house water softener/filter system. A May 2026 reviewer had bad valves diagnosed and new sink hardware installed. In a 2023 review, a customer said Joe replaced a furnace and was able to honestly diagnose the problem 2 other companies were unable to find and fix last winter. Another 2023 reviewer, with a broken heat exchanger on a tankless water heater, said other companies all gave an insanely pricey service charge just for the replacement, while Joe's job was perfectly done with reasonable price. In an August 2025 review, a customer had a shower installed, making a half bath into a 3/4 bath. A June 2026 reviewer who had been using Joe and his team for almost 20 years wrote that he always tells you what you need and never what is the most expensive, with clear explanations of what went wrong and options for how to fix.

I hired Ferguson because I felt I was getting jerked around by my old HVAC contractor (I saw a lot of bad reviews on their site ). Ferguson was very professional, pointed out there was a problem with the old HVAC installation (Was installed two years prior & the guy who installed had a bad attitude ) . They corrected the problem. I see there’s a lot of reviews on the site 99% positive. I always tell people to look at the negative reviews because that tells you the story of a business) I don’t think there’s any contractor in the area That has such a high percentage of positive reviews, Good on Ferguson. I would definitely hire them again.
Flushed both of our HVAC lines with hot water - completely clearing them of build up. Ingenious process without using any chemicals. Flushed out the hot water tank in the process as well.
Had an issue with my HVAC. They were very responsive and were able to squeeze me in that week. They were very professional and communicated very well. Would use again!
I've been using Joe and his team for almost 20 years. Always tells you what you need and never what is the most expensive. Clear explanations of what went wrong, options for how to fix and best recommendation for not to have things break again. THE MOST TRUSTWORTHY plumbers on the planet!
Responsive, arrived when they said they would, the technician was very nice, he did a fantastic job, and he cleaned the area up better than he found it when he arrived. Outstanding job and service (installed two hot water tanks).
