Customer Reviews

Evan Kelley

Zac C. from LeBlanc Heating and Plumbing did a spectacular job troubleshooting a plumbing issue in our home. He was quick to isolate two faulty valves and had them replaced quickly. Zac was polite, professional and easy to work with. LeBlanc’s consistently strong customer service is why I keep coming back.

Steven Count

We just had our 20 yr old+ A/C and furnace replaced. Had interviews with 2 others and decided to go with A.J. Leblanc because they offered the widest selection of options and very competitive pricing. Brian in sales was fantastic, installers Mike and Eddie were professional, on task and got the job done! Very pleased, no regrets, would highly recommend to anyone in similar situation.

Colby Chiang

The team at AJ Leblanc did a great job with our heat pump installation. They were knowledgeable and offered creative solutions that worked well with our retrofit. The installation team was reliable and communicated well and left a clean work site. Very happy with the results and would definitely use them again

This afternoon Mike and Eddie arrived for my scheduled appointment to swap out my hot water heater. They were very considerate of my home and worked quickly to get the job done right. They even took the time to walk me through the new hot water heater and answered all my questions! They both were both a great representation of this company! I have been a customer of AJ Leblanc’s for many many years for everything plumbing and heating related and today was another example of why I stick with them!

Bob Colombo

We've been customers of LeBlanc Heating, Plumbing (etc.) since 2018, when they replaced our boiler and installed ductless mini-split systems in our home. We now have them come out every year to maintain those systems, plus we also use them for all of our plumbing needs. Speaking of plumbing needs, Zac and his associate came to our house during Thanksgiving week in 2025. The 11-year-old up-flush (also known as an "ejector") toilet in our finished basement's bathroom evidently failed, which Zac diagnosed very quickly. He was fantastic in explaining our options and finding a replacement that was in stock and would fit into the existing fittings without fuss. He then coordinated having one of their workers back at the shop pick it up and deliver it to our house, while the two of them got a jump on removing the old toilet and preparing for the new installation. Our hope was to have the bathroom operating again by Thanksgiving, but thanks to Zac's skills and support from the others at LeBlanc, the job was completed within a few hours that same afternoon. On top of that, we found the overall price to be very, VERY reasonable! In closing, here are the terms that come to mind when thinking of the service level of Zac and the others at AJ LeBlanc: reasonable rates, professional, prompt, excellent communication, courteous, effective/efficient, knowledgeable. We're glad to consider them not only a service provider, but really "our partners" in providing and servicing a couple of the core systems in our house. We're huge fans.
