Laird & Son was super responsive when I called with no heat after a 10 month old Boiler that stopped working. Greg was our technician and he was amazing. By far the best technician we have had come in 20 years to our house. Greg identified a defect, got our heat back and everything is being done under warranty. An amazing company and encourage people to support them. Thanks. Meredith
Could not be more pleased with the courteous and professional service. My furnace had malfunctioned nearly three weeks before I sought help from Laird & Son so I had already done a deep dive into troubleshooting the issue and had a pretty good idea what the problem was. Ringo, their diagnostics tech rep, arrived on time, was very professional and diagnosed the problem that I had anticipated through my crude lay efforts, using sophisticated diagnostic tools. While I regret having to replace my 17 year old furnace, the quote I received was happily below my expectations and if the installation team is half as good as Ringo was, I will consider myself most fortunate.
My son recommended Laird & Son based on the excellent job they did in his house. I called on them to fix the mess another contractor left when they worked on the furnace in my house. I am so glad I choose L & S since now I know how quiet a well cared for heater should work. I have been in this house more than 25 years and have never been so happy with our furnace
We are thrilled with the work that Laird and Son did installing our water heater/boiler combi for us! The technicians were remarkably friendly and downright joyful all day, a delight to have in the house. Their professionalism, cleanliness, and final work so far exceeded our expectations it was almost funny. The truth is, we called them to reinstall a horrifically botched job by another large and generally well-reviewed company in the neighbourhood. Absolutely everything needed to be redone from scratch, and they didn’t cut a single corner. It was a long day, and by the end of it, our boiler room was unrecognizable. One of the technicians joked about using a level when installing the pipes and I would swear they did. The precision and detail of everything is incredible and when they left you would never know they had been there for how clean it was. After the stressful experience of the first completely unprofessional and incomplete installation, everything Laird and Son did put us at complete ease, and we couldn’t possibly be happier with the end result. A truly incredible experience all around.
