An inside look at Temspec.

We believe in making Living and Learning Better by providing Quiet, Efficient HVAC products that work Perfectly in the spaces our Customers Create – Quickly and Without Surprises.

Temspec Inc. began operations in 1971. At that time the company manufactured concealed vertical stack fan coil units for installation in high-rise condominiums, apartments, student dormitories, retirement residences and hotels.

In 1983 Temspec underwent a major change. The company introduced a unit ventilator with electric heat used primarily in school portables. That success led to the development of hot & chilled water vertical unit ventilators for standard classroom applications. The Temspec design provided a small footprint, easy maintenance and a quiet operation which was revolutionary for its time.

By the late 1980’s, Temspec’s unit design advanced to include direct expansion air conditioning, initially by means of a split DX coil using a separate condensing unit evolving to units with self-contained cooling. 2000 saw the introduction of a high-rise vertical stack fan coil unit with a finished cabinet for exposed applications. This unit was primarily targeted at high-rise residential building renovation projects. In 2003, the company introduced its first air-to-air heat pump for classroom applications. Since then, the company has progressively developed a complete line of energy efficient “green” alternatives including geothermal heat pumps, and energy recovery options.  In 2018, Temspec launched the “LEAF” vertical fan coil product which offers the worlds highest efficiency fan technology utilizing an integrated backward inclined impeller fan and EC motor.

Today, Temspec is a leading designer and manufacturer of single zone HVAC equipment. The company holds a significant and growing share of the North American HVAC market for high-rise and classroom applications.

As a second generation owner, Temspec has been a large part of my life since my junior year of high school.  I “grew up” through the Field Service and Research and Development sides of our business.  My formal education involved an Industrial Engineering degree from Ryerson and I am a graduate of Harvard’s OPM program.


I love working with a community of folks who are concerned about the full life cycle cost of conditioning the air we live, study and work in – and continuously learning to do this better and more efficiently.
