About Us

We are a third generation, family owned and operated business that offers the highest quality in residential and commercial heating, cooling, and hydronic equipment installations and service.
The family business we run is as much about building new relationships with our customers, as it is about providing fantastic HVAC service experiences in our neighbourhood and surrounding areas. We don’t just work here, we also live here, and have been a part of the community since our patriarch, Lawrence Vasilak, planted his roots in Hamilton over 75 years ago.
Lawrence believed that if you provided customers with both good value that meets their needs and a solid foundation of trust, dependability, service, quality, and responsiveness, that those customers would be lifelong ones. His proud passion for high quality service has been passed down to his family and employees, ensuring that his legacy of integrity, and commitment to values, is never lost.
Today, the business environment has changed, as has the pace at which the world moves, however, at HAMCO we will deliver on our commitment to you. We pride ourselves on following the family values that have become the HAMCO standard set by Lawrence Vasilak, and carrying that reputation to every service call, sale, and installation we perform.
We continue to be the go-to residential and commercial HVAC experts in the Hamilton, Burlington, Oakville, and surrounding area. We look forward to serving you and your heating, cooling, or hydronic needs.
Call us today for more information on our service and maintenance plans, plus find out what amazing products we carry that will create the most comfortable space to be in.
Yours in HVAC,
John, Tom, & the HAMCO Family.
