About Us

Company Overview

Indoor Air Quality, Inc., a Denver HVAC company, was established in 2001 by Joe Collida and Pat Comeford in Aurora, Colorado. Joe and Pat continue to manage the company today and take pride in providing a family environment for all of our employees. Both owners are very “hands-on” in all aspects of the business. In fact, Joe and Pat personally provide heating and air conditioning services to virtually all of our Denver metro clients with HVAC needs.

Unsurpassed HVAC/R Training

Indoor Air Quality, Inc. was trained by the Comfort Institute, a trade organization that combines the heating, ventilation, air-conditioning, and refrigeration (HVAC/R) industry with building science. This gives us the knowledge to diagnose and fix heating and air conditioning problems in your home that other contractors may overlook.

Our team of professional HVAC/R technicians has over 60 years of combined industry experience. The heating and air conditioning industry is constantly changing, and we make education in our field a top priority for every employee.

Every technician at Indoor Air Quality, Inc. is North American Technician Excellence, Inc. (NATE) certified. The NATE certification program is recognized by the HVAC/R industry as the leading non-profit technician certification program. NATE certification requires continued education to maintain certification status, so all of our technicians regularly attend training courses and seminars on new products and techniques.

The bottom line? We can help save you money by correcting minor problems before they become significant and direct you toward more energy-efficient systems to heat and cool your home.
