“Andrew and the crew at intelligent Design were efficient & professional. I Could not have asked for a better experience.”

~Mark G., Tucson

Here are written testimonials from past customers:

"Hi my name is Peggy I am an artist and my husband is a doctor.    My AC went out and I called the company that I had been using to service my AC(one of the big companies in town).  They were not responding in a timely manner and during their routine maintenance I felt they were always trying to sell me something.  I then searched on the internet for someone who could service my AC quickly because it is over 100 degrees in monsoon season.  I was in emergency mode.  I found Intelligent Design and they came out the same day that I called within a few hours.  They explained the different options for repair and replacement and the different systems available and compared the costs for me.  I felt with their vast knowledge and integrity that I could trust them and decided to purchase a high SEER system.  Also their prices were really competitive comparison.  Once I had agreed to purchase they promptly brought and set up some portable air conditioning systems to keep my husband and I cool for the rest of the day and night!!!  I want to highlight how appreciative I am of this service.  It was a wonderful display of their commitment to their customers.  I have never experience this high level of customer service from an AC company.  They scheduled me for an emergency install the very next day.   The crew came in first thing in the morning and did the install in one day.  The crew was clean cut,  very polite, professional,  and left no mess behind.  I COULD NOT RECOMMEND THIS COMPANY HIGHER!!!"

"I met Andrew Dobbins the owner of Intelligent Design at a Christian networking group at our church Victory Worship Center.  I was talking to someone else about my extreme allergic reaction to mold and that we had a mold issue in our home.  Andrew then mentioned that he had dealt with in home toxins before with other customers and described the device that could alleviate my problem.  Andrew has a wealth of knowledge on indoor air quality and he helped us understand the product prior to purchase.  Shortly thereafter we decided to purchase the system.  Andrew had guaranteed that if it didn’t do what we needed he would happily remove it and give us a full refund in writing. One of the service techs showed up and had the system installed in under an hour.  They left no mess behind and were very friendly. We have now had the system for 3 months now.  I have noticed a huge difference when I begin to have an allergic reaction I just turn my HVAC system on and my symptoms subside with in 1/2 hour.  Prior I was debilitated and could barely work.  I was getting nauseous because my reaction was so severe.  This system has helped changing my life and ability to function.  I would recommend this devise to anyone who has allergies or lots of dust in their home.   Also I have had a wonderful experience with Intelligent Design and Andrew the owner."

Installation of humidifier with high definition, programmable digital thermostat with exterior temperature sensor.

"My name is Richard Nelson and I am a retired USAF officer employed as a civilian flier for the F-4.  My wife Cindy works in an elementary school library. We met Andrew at the Sahba Home Show in Tucson recently and were interested in a home energy audit.  This is a service his company provides and is certified for.  Andrew is an intelligent, courteous business man who we found to be very knowledgeable and enthusiastic about his company and products. After an informed presentation and discussion we purchased a humidifier and were eagerly awaiting the installation.  The servicemen from Intelligent Design arrived promptly at the scheduled time on the agreed date and got right to work. They were polite, courteous and efficient in their work during the few hours they were here and cleaned up before leaving. The end result is great!  The thermostat is so easy to program and make daily changes, if necessary.  The air in the house is comfortable and we are so pleased we made this improvement in our home.  We look forward to doing more business with Andrew again.  If you are considering a new AC, humidifier, or adding any other air improvement to your home, we highly recommend Intelligent Design."

"Andrew came out to give me an estimate on my HVAC system the morning after I called him. He did a thorough evaluation of my needs and recommended a Lennox product that would cool and heat my house better than other brands. The work began the next day and was completed on the second day so that we had a comfortable home by Friday evening. The workmanship was superb and all the old equipment was hauled away and the area was clean as before. Andrew came out on Saturday to do a walk through and answer any question I had. I would strongly recommend Intelligent Design to anyone looking for quality service at a good price."


"We went with Intelligent Design because we knew that the installation is the most important thing with an AC purchase. Andrew did a comprehensive check through the house during the estimate and had an excellent price for all the work that was to be done. Also the certifications of the crew along with the experience that they require before hiring their installers was of great importance to us. The owner was very responsive to our concern about the carpet and has now scheduled for our entire house to be cleaned by a carpet cleaning company. What great customer service. Our new system is extremely quiet and much more efficient."

"I found Intelligent Design on a manufactures recommended companies web site along with other contractors from various manufactures. When Andrew Dobbins the owner came out He was extremely knowledgeable, and was the only one to provide the proper evaluation for correct sizing and have a solution for each of the issues that I was having. He asked me questions to identify my problems and provided the best solutions to fix them. I was leery about their ability to fix the problems as Andrew said they were going to but, I trusted them and went ahead with the work. THEY FIXED EVERY ISSUE THAT I HAD."

"I am very pleased with this companies service and installation. I had gotten multiple quotes. I chose Intelligent Design because of a competitive price and excellent service. The estimate was very detailed and comprehensive. The other company said there were things that needed to be done that were not necessary. Andrew Dobbins the owner was honest with me about what I did need. I highly recommend using this company."


"My name is Lonnie Wiles.  I am a retired civil engineer.  I found Intelligent Design at the April SAHBA home show.  My wife and I walked by many HVAC companies at the home show and found ourselves impressed by intelligent Design.  We already had another quote but were much more impressed with Intelligent Design.  We chose to go with Intelligent Design because they sized the system based on a computer engineering system called a heat load calculation and others were only sizing based on the square footage.  Also, Andrew Dobbins, the owner, saw a number of flaws in the existing system with a lot of roof top duct work and the uneven cooling and heataing that we had in our house.  He proposed a system design that made perfect sense to us.  By removing the roof top ducting and adding a mini split (ductless heat pump) in our room addition, we now save a ton of money on our electric bill and we now have perfectly balanced air.  Also, we bought an air purification system from Lennox for our allergies.  The New Lennox 15 SEER package system is way quieter than our old system.  I would be happy to refer them to our friends, family and neighbors."

"I live in Saddlebrooke.  My wife and I purchased an activated carbon filter and air scrubber type filters from Andrew Dobbins of Intelligent Designs.  We met Andrew at the Home Show at TCC.  Andrew was a very professional and knowledgeable young man.  Living in the desert, a primary concern that we had was dust.  Thus the activated carbon filters.  Secondly, my wife has asthma and we both have allergies.  Thus we bought the air scrubbers.  My wife had a single room air scrubber and now we have a full house.  As to the installation of the products, we couldn’t be happier.  Installation dates were made to our convenience and the installers were always on time.  I recommend Intelligent Designs and Andrew for any of your heating and air conditioning needs."


"Intelligent Design was outstanding when we had new cooling and solar installed.  We have been looking for a replacement furnace and A/C unit for a long time and decided to get solar at the same time.  We got two other estimates for solar before talking to Andrew of Intelligent Design.  Andrew was able to provide a whole package and address all our concerns and issues taking into consideration our specific needs.  The installation of the furnace and a/c was without a hitch.  The workers were knowledgeable, polite, clean, and efficient.  They came on time, completed all the work as specified, and left our home clean.  I would definitely recommend Intelligent Design to my neighbors and friends.  As a matter of fact, I have already shared our experience with some of our neighbors who are looking for similar equipment and services. The equipment itself is working great."

Total and complete satisfaction.  

I am a retired SGT. Major.  I was referred to Intelligent Design by a friend since my AC and Heating system in my house was getting older.  Upon contact with them they did a complete survey for sizing and analysis of the home and my needs to make sure to find out exactly what I wanted.  Upon completion of the survey they provided 3 system options based on what I said that I wanted and provided 36 months no interest financing.  The install crew and craftsmanship was fantastic.  The complete product is amazing.  Also they provided me with a preventative maintenance package.  I couldn’t be happier with the company professionalism and quality.
