Our Services

Boiler Installations & Repair

Boilers are a very efficient way to heat your home. As opposed to a furnace which heats the air, boilers heat up liquid that circulates through a hydronic system to various devices that distribute heat such as radiators or in-floor loops. Contact us to see which system works best for your home, office, or shop!

Commercial Heating Needs

Commercial HVAC systems are more complex than residential systems and require the dedication and expertise of professionals like HighFlow. We know that commercial HVAC repairs can happen anytime, day or night. We offer emergency service 24/7 in the Hamilton, Niagara and Southern Ontario regions.

Why Choose Highflow Mechanical?

Wade was professional and fixed [the] issue. He explained everything to me in detail ( I know nothing … so this was significant for me). Their price was reasonable and worth having the piece of mind that I was walked through the steps of installation and understand the issue and how it was properly fixed. We would 100 percent use them again.

“ From the start they were great to work with, and I would highly recommend them. They arrived quickly, and Wade was highly knowledgeable. He identified the potential issue in short order, and provided options to resolve the issue. He then set to work and quickly repaired the issue. All the while being mindful to maintain a tidy workspace, and ensure I was comfortable with the work done. Overall a great experience with this company.”
