Andrew Dobbins and family

In 2002, after serving in the United States Marine Corps as Presidential security at HMX-1 in Quantico, VA., Andrew Dobbins left the Corps and entered the world of air conditioning and heating. The Corps had impressed upon Andrew a great appreciation for attention to detail and processes which benefited him as he excelled in the fields of product differentiation, heat load engineering, system customization, system design and estimation. Over the next several years Andrew became very proficient in all aspects of residential system design and accrued several different certifications including EPA certification, Building Performance Institute (BPI) certification (Building Analyst and AC/Heat Pump), heat load certification and others, which finally culminated in Andrew attaining his Arizona Registrar of Contractors CR39 residential and commercial HVAC license.

In 2009, after seeing how things should be done versus how most companies were doing business, Andrew felt he had to go into business for himself in order for the customer to receive the quality and integrity they deserve. Starting with three staff members and working out of a home garage, Andrew went all in, selling his truck for $20,000 for capital to start his own company.

Today Intelligent Design employs over 40 people year round and works from their new property which was purchased in 2013. Each lead installer for Intelligent Design has a minimum of 10 years experience and every service technician is certified with an average experience of 17 years.

Because of Intelligent Design’s great attention to detail and complete customer satisfaction guarantees, we are now the highest rated HVAC company in all of Southern Arizona specializing in: residential system repair and replacement, indoor air quality solutions, custom duct repair and design, custom homes and commercial service and replacement.

In 2015 Intelligent Design started a new plumbing division to better serve their customers. The new plumbing division provides all plumbing services which include drain cleaning, water heater replacement, all plumbing repairs and whole house water softening and water treatment.

Intelligent Design continues to grow each and every day because of our high quality personnel and because of the wonderful people of Southern Arizona. We are so glad that with the multitude of companies you could do business with, you choose to work with companies like ours, whose sole focus is the customer and doing things the correct way.

This community is the reason we are who we are, and we show our support by taking part in community contributions around the area. In fact, we partner and support various organizations, such as the Hope Center, Gospel Rescue Mission, Hands of Hope, and Teen Challenge!

Thank you Southern Arizona for welcoming our company and helping us to so quickly become the best and highest rated HVAC company here. We appreciate you!
