Theriault Plumbing & Heating Ltd.

We are more than pleased with the excellent response to our recent plumbing dilemma. From the initial phone call to the high quality of workmanship by Pascal, we would highly recommend this company. Courteous, efficient service from start to finish! Thanks again to the Theriault Team!

My husband and I have had a long business relationship with Theriault Plumbing spanning approximately 25 years. We initially engaged their services when we had an apartment building consisting of five units. A new gas/hot water furnace was installed to supply all units, each having their own thermostat and replacing the original heating system. In addition to the cost saving measures, this unit also allowed for more free space in the furnace room, as FIVE hot water tanks were replaced by ONE gas/heat/hot water-on-demand furnace. Within the first three months of using this new system, we noticed a great decrease in our utility bills. After one full year of usage, our gas bills decreased by approximately $ 4,200.00. Our relationship continued as we purchased a new home heated by a gas furnace. Theriault Plumbing did yearly inspections, duct cleaning and repairs as needed. This brings me to this April, 2019, when we had a new even Higher Efficiency Lennox furnace installed to replace our old High Efficiency Lennox furnace that lasted 20 years. WELL, WE WERE BLOWN AWAY BY THE QUALITY OF THE SERVICE, THE KNOWLEDGEABLE PERSONNEL AND THE PLEASANTLY COMFORTABLE ATMOSPHERE. We have always had great service and skilled, professional workers throughout the years, but there was something different about the two young men that installed the furnace. It is hard to explain, as it was more of a “sense of calmness and easy competence” that made us feel reassured and totally at ease. If Theriault Plumbing continues to employ the type of workers described above, we believe a new era is coming. In a world where so many things are going wrong, THERIAULT PLUMBING IS SURE DOING SOMETHING RIGHT! Our sincere Thanks and ????, we definitely recommend Theriault Plumbing Celia and Mike Huard, Timmins, Ontario

Had my furnace and central air, tankless hot water and air exchanger from them. Excellent work and after sales service.

I requested a quote for an HVAC system (central air & furnace) I did like the detail the tech went into and amazing knowledge on products (both high end Lenoxx & low end Payne) and services they offer but after calling several other HVAC companies, theriault ended up being the most expensive out of them all by quite a large number for a very similar system to the mid/high end units available elsewhere. If high price of units/instilation isn't an issue for you, they do have a finance option available at the time of this review.

Worst service ever!! From customer service to the actual work. The short version is that they sent me a contractor who has not a clue what he is doing and who broke a part everytime he came to fix something. Even tho he broke the parts I still get charged for the part and the labour. The final straw was that same contractor came back about 4 weeks later (because he "had emergency surgery" which i had no choice but to wait even tho they had many other contractors) and installed the part and demanded my old one back even tho i had written proof from the manufacturer they they dont need it back. Eventually the contactor took out the new part which he just installed and left me hanging with a unserviceable unit. Police were called because he refused to get out of my house as I asked him to do so. My daughter was upstairs sleeping and so I called the police. In conclusion, this was the worst experience of my life and I found out after that they have done this to many other people.
