About us



We can work on plan and specification projects that are out for bid, or we can help you engineer your design/build project with our heating, air conditioning, ventilation and air filtration calculation tools.  We can also work with engineering firms to provide solutions for our customers' needs.

Our History


John Sefton has gained a wealth of experience working in the HVAC industry over the span of the past five decades.  In April, 2004, John decided to open his own business as a manufacturer's representative to the local construction business, forming HVAC Rep Enterprises, an addition to a corporation he had sold equipment through since 1982.  John brought his knowledge of air movement and conditioning as well as a trusting customer base into the new company and began to grow his line, picking up several ventilation, heating, and air conditioning lines.


The year 2008 brought with it several challenges to the construction industry in general and to HVAC Rep Enterprises, and an opportunity as well.  John hired his son, Ty Sefton, to come aboard and learn the trade.  As the father/son team grew in knowledge, they also grew the line by picking up air filtration and custom air conditioning lines.  We have since picked up sound attenuation/silencers.
