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 3 staff 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!

Had a BIG leak at the water main on a Friday at 4:30 pm. Cori got there as soon as he could and couldn’t repair that night, but was back bright and early Saturday to fit a temporary line. He came back to finish the repair quickly and professionally. Very polite and helpful. Price was better than I expected, pleased with that too!

I have been with intelligent design for several years.  Their staff has ALWAYS been prompt and courteous and answer all my questions.
Today, I would like to state that Robert, who came out to do plumbing repairs, was the nicest, most helpful young man I have met in years.  He is courteous, and helped me to understand all that he was doing.  He loves working for Intelligent Design.  And although he has been there a short time, loves his work.  You truly have a star in Robert.

These guys are legit! I had a terrific experience with this company. Our air conditioning went out last month during one of the hottest weeks of the summer. The main fan just stopped spinning. My wife and I watched all the YouTube videos we could find before realizing we were going to need professional assistance.

The rep came out the very next morning. He checked both of our ac units and walked me through, step by step, what he was doing.  The fan and power source both needed to be replaced on the main unit. He went and got the OEM parts and returned within a few hours to complete the job. The second unit still had a little life left on it, so instead of pressuring me to replace it, he offered to return and repair whenever we decided to call. He was very thorough, did a terrific job cleaning both units, and was professional and organized. I felt like I was treated fairly and honestly.

I’m sorry to comment on this, but I’m bothered by the yelpers on here who have complained about being over charged. Anyone that expects to get a free diagnosis, then buy third party parts “at cost”, and repair the AC themselves is not living in reality. I would challenge you to name one industry, trade, or service that works that way. A mechanic doesn’t bring his garage to your home, diagnose your car’s problem, and direct you how to fix your car and where to buy the parts. That’s not reality. You either pay a “bench” fee for the analysis and trip out to your home, or you get it as credit toward your purchase. These guys are honest, know their stuff, and a fair. This is a very special skill and they exhibited a fantastic response time. Thank you!

I have used Intelligent Design twice in the past three months. First I replaced an air conditioning unit and secondly I used their plumbing division to replace my hot water heater and kitchen faucets. In both cases the technicians were incredibly knowledgeable, professional, on time, informative, and efficient. They were able to troubleshoot my problems and recommend the best options for me. They showed up when they said they would, called ahead of time to give their e.t.a., and followed up afterward. I would highly recommend using Intelligent Design for your heating, cooling, and plumbing needs.

Technician arrived on time – he was most efficient. He checked everything out with a minimum of fuss. All was good. I’ve been pleased with every technician who has come to my place from Intelligent Design. The front office is responsive and easy to work with. I am sticking with these folks!

Albert came out to flush out our hot water heater & check the sewer line. He performed both tasks quickly and efficiently. He was pleasant to talk with and very courteous. Elmo and Kevin arrived a short time later to perform a maintenance check on our AC system. They were also very polite and took care not to track mud into the house. They did an excellent job checking the filter and equipment. All arrived within the window of time expected. We highly recommend this company based on previous and current experiences.

Service, explanations, etc. were excellent from Elmo! Like the “old days,” he was courteous, helpful, answered all questions we had. He was the nicest technician we’ve had out here in a long time. We hope to have Elmo come back for our next service!!

They are incredible professional and courteous. I am a single female and called them after I felt another company was trying to take advantage. They confirmed that some of what the tech had told me was wrong and trying to get me to buy an entirely new HVAC. The other recommendations were sound, but optional, and they didn’t charge as much. They explain everything very thoroughly and are very helpful! They recently installed a new thermostat, and the tech was even nice enough to set all the programming and explain to me how the thermostat worked. They installed one that I purchased myself, so I thought that was extra nice. They also helped me find custom air filters for my unit as the standard sizes at hardware stores don’t fit my unit. I didn’t feel pressured to buy any maintenance packages or do anything I didn’t want to. I highly recommend their services!

Very helpful service, honest and willing to work with me to fix my rusty and old water heater. I’ve worked with intelligent design before on my air conditioning unit, I decided to call them back for their honesty and reliability.
