“Over the years we have retained McCallum HVAC Designs Inc. for HVAC designs of our custom homes and renovation projects. Doug and his team are always a pleasure to work with, knowledgeable and reliable.
The final HVAC drawings are well presented and very organized.”

Richard Kossak

“We’ve had the pleasure to work with McCallum on a number of projects, each with its own unique challenges. On all of them McCallum has always been willing to work with us collaboratively to find solutions that not only perform well, but stay true to our original design intent.”

Vanessa Fong Architect

“McCallum HVAC have become our go-to solution for thoughtful, professional and responsive heating system design services. We’ve worked with many providers of these services over the years and struggled with poor quality work, slow turnaround, sloppy drafting, lack of knowledge and indifference to customer service. Working with McCallum’s team, we have none of these issues. Real pros, great communicators, and good people. We highly recommend them!”

“We have worked with McCallum HVAC Design Inc. since 2006 and during this time they have looked after all our HVAC design and consulting needs. As our building code changes along with the technology and building practices, McCallum HVAC continues to be on top and acquainted of code updates as well as new and improved equipment and systems. We rely on McCallum HVAC for our Heat Loss and Duct Design for both permit submittal and on site installation. Their staff and organization always make for an efficient and great turnaround.”

Neil Watson

“I have used Doug McCallum services for over 8 years and he is by far my first pick for planning and designing heat loss/heat gain and duct design drawings for all my projects. As an architectural home designer, I require good consultants that are professional, well informed in their trade as well as able to meet my deadlines and Doug has constantly met all my expectations. Doug has an amazing team that has the capabilities to work on a small residential project such as small renovation, additions, and minor interior alteration but he can also accommodate larger project such as sub-divisions and large custom house. I recommend McCallum HVAC Design to all my clients and anybody who require HVAC drawings.”
