Create and sustain productive, healthy, and efficient building environments.

The ENTEC Difference


Too often, mechanical system performance disappoints building owners. By discovering our customers’ needs and following tried-and-true service practices, ENTEC overcomes our industry’s commitment to the
status quo.

ENTEC commits to offer the best in industry performance. We provide the same professional service whether we repair the most basic heating and air conditioning systems or ensure the latest, most complex environmental system’s reliable performance — every customer deserves that.

Our Promise


  •     Second to none service, quality and value
  •     Honest and realistic recommendations every time
  •     Do the right thing in every situation.

Building environments impact employee productivity and customer loyalty. It never pays to settle for the second-best when it comes to building system solutions. With 41 years in the industry, businesses across Illinois, Iowa, and Missouri know they can rely on ENTEC for all their heating, cooling, and building automation needs. We commit to being the best, and we make sure every team member has the tools and training needed to be just that.
