Coal Harbour Mechanical has earned a reputation for good work and honest advice. But the thing we’re most proud of is our commitment to treating people right. See what our customers say about us on Google.

Working with Coal Harbour Mechanical we were able to swiftly and competitively offer a service that would work well within our budget so that we could remediate heating issues in our house during a cold spell! They had provided heaters as well as made quick work of the installation within days of setting up and confirming numbers. In addition, at least for what I am looking for when contacting a service organization is not just the face value of the service, but the add-on value that truly shows partnership. Coal Harbour Mechanical does this in a way that made us feel secure we were going to be taken care of by providing reasoning to furnace choices they install and even prescribing opt-outs to their own services that may not be immediately needed when working on a quote. This all came together in a great service offering and was reason for why we chose Coal Harbour Mechanical instead of other organizations we were considering when replacing our furnace!And of course...the service itself was done smoothly, but I emphasize this as a function of the task at hand, not the add-on value that comes with partnership.

At the beginning of the recent heat wave our air con decided not to work. We reached out to the Coal Harbour Mechanical and explained the importance of keeping our animal patients cool . In spite of being swamped, Taylor came out and had things fixed in no time. Each member of the Coal Harbour Mechanical team was friendly, professional and timely, every step of the way. I cannot thank them enough for their exceptional service.Dr Tina Gemeinhardt

We had a lot of work done this year by Coal Harbour Mechanical including water pipe replacement, a new bathroom and ductless heating/cooling system installed in our home. Workers did well with the variety of work that was happening and adjusted as they went along if required. Shawn did a lot of leg work and help coordinated the job and was helpful in selecting the equipment that would best suit our home.

My heating furnace flamed out feb 2021 at the peak of cold wave. I contacted Coal Harbour Mechanical service group. The lady dispatcher was very friendly. Took my information and assured me inspite of being busy will send a technician as soon as they can. Technician came and diagnosed the issue and gave me estimate to replace parts. Their estimate is very reasonable. I know that because I enquired around to know what are costs of replacing cost. I believe their estimate is honest one.They promptly followed up next day replaced parts and got my heating furnace working. Great work by two young technicians Taylor and Kyle. Technicians were friendly and did great job. Overall I am happy with their work and will definitely recommend them.

We had our hot water heater fail and called first thing in the morning. To our delight Keltie and her team arrived onsite within 1/2 an hour and determined that our 11 year old tank couldn't be repaired and needed to be replaced. She made a call and had a quote sent within 5 minutes, a new tank delivered within an hour. Even though issues were encountered, her professionalism and quick response made it a no hassle installation. Couldn't be happier and more appreciative.

Coal Harbour Mechanical has installed a Daikin heat pump with ductless splits as well as replaced a Navien tankless water heater at my home. In each case their staff were responsive, friendly, knowledgeable and helpful. The jobs were done with great care, impeccable workmanship with great attention to detail. I would highly recommend Coal Harbour Mechanical!

James came to our house and was able to fix our heating in no time at all. He was very nice, respectful and wore the proper PPE to make sure we felt safe. He was able to also help adjust our bath tub faucet pressure which was a life changer. He provided top notch service and was extremely efficient.

Mike was excellent. He identified a problem that my old heating company was not able to repair. The system is up and running thanks to Mike for a job well done. I must also thank Tiffany for her efficient management.I am glad to support a local company.
