About Us
Calgary's Boiler Experts Since 1996
A family-owned business built on one principle: specialize in what you know. For nearly three decades, DHL Mechanical has focused exclusively on boiler repair, installation, and radiant heating across Calgary and Western Canada.
Boiler and hydronic heating specialist with nearly three decades of hands-on experience in Calgary's most demanding climate. Mark founded DHL Mechanical with a simple commitment: do one thing, and do it better than anyone.
Built on Boilers. Nothing Else.
Most HVAC companies in Calgary split their attention between furnaces, air conditioning, ductwork, and a dozen other services. Boilers get treated as an afterthought — something they'll "figure out" when the call comes in.
DHL Mechanical was built differently. When Mark Davie founded the company in 1996, he made a deliberate choice to specialize exclusively in boiler systems and radiant floor heating. That single-minded focus has defined every decision since — from the technicians we hire to the parts we stock to the training we invest in.
Nearly three decades later, that focus is our biggest competitive advantage. When a Calgary homeowner calls at 10 PM with a boiler locked out in -35°C, we don't send a furnace technician who has to Google the manual. We send a boiler specialist who already knows the system, likely has the part on the truck, and can diagnose the issue before they pull out a tool.
We serve homeowners, property managers, commercial building operators, and contractors across Calgary and Western Canada. Whether it's a straightforward boiler repair, a full high-efficiency boiler installation, or a complex multi-zone radiant heating system for new construction, DHL Mechanical is the team Calgary trusts.
Our Journey
The Principles Behind Every Job
Every boiler call, installation, and maintenance visit is guided by four non-negotiable commitments to our clients.
Trust & Transparency
No surprises. We quote the job before we start, arrive when we say we will, and charge exactly what we quoted. Trust is earned through consistency, and we've been earning it since 1996.
Safety First — Always
Modern boiler systems involve gas lines, high-pressure water, and exhaust venting. Every DHL technician is fully licensed, follows manufacturer specifications precisely, and never cuts corners. Your family's safety is non-negotiable.
Informed Decisions
Unexpected breakdowns can force rushed decisions. Even under pressure, we make sure you understand your options, know your costs, and have the information to make the right call for your home and budget.
Precision Craftsmanship
High-efficiency boilers demand precision installation to perform at rated efficiency. We combine modern technical training with old-school attention to detail — because a shortcut today becomes a service call tomorrow.
