Central A/C Service or Repair
During a service in May 2025, a technician suggested potential mold issues but failed to document these concerns in the subsequent paperwork. Additionally, during a winter check in November 2025, a different technician warned me of necessary repairs and implied a potential fire hazard related to my heater; however, this information was also absent from the official records in both situations. After seeking a second opinion from another company that deemed my system safe, I expressed my dissatisfaction to owner Andrew Dobbins. I requested a prorated refund for the three years left of my membership. A follow-up from Service Manager, Paul Matthews, indicated that my system was not as dirty as originally claimed, prompting me to question the integrity of the services provided. My request for a refund was declined, and a subsequent call with Mr. Dobbins escalated, as he accused me of attempting to extort money, rather than addressing my legitimate concerns about his technicians' practices

Post sales follow up by my salesperson is non existent. I needed some information regarding tax credits as promised as I was completing my tax return. I called the office requesting that my sales person give me a call back. I only had a couple questions. Then I left a message on his contact number. I did not receive any call. So much for being a "Diamond Club" member.

We had a clogged kitchen sink and called Intelligent Design whom we had used twice in the past. While at first they had no openings for days, the kind person we spoke with checked with her supervisor and they said they would squeeze us in for the next day. I was fully expecting to wait all day for the scheduled jobs to be completed, but got a call late morning from Marty who said he was 20 minutes away, I was thrilled. Marty arrived as promised and quickly assessed the problem, deciding he could work it from an outside clean-out. As expected in these times Marty arrived masked, we masked also. When Marty was getting to work he asked permission to remove his mask and that we distance ourselves. He got the clogged cleared in minutes and had us run the sink to ensure it was truly cleared. Marty was very personable, friendly, and highly professional. We were done in about 20 minutes and the price was extremely fair, with no adders or surprises. I certainly liked Marty and even more Intelligent Design which has fair prices and very capable plumbers.

installed May 9 2020 and nothing but trouble with complying with THEIR contract. No attic support, warped outdoor compressor pad, NO COPPER TUBING PROTECTION (from the bare metal cutouts in the unit), no room balancing, noise, Noise, NOISE. I think that they believe I will just give up and not make them DO THEIR JOB but they would be wrong! This unit was not donated to us, we paid $32k CASH and that was OUR mistake but we are calling our lawyer. Eight service calls for a new install is out frigging rageous!!!!

The plumber tore apart my bathroom with a jack hammer and left a big gaping hole in the floor. After pressuring him to cement it in, he did albeit very sloppily. I had to hire an independent tiler to smooth out the cement, straighten the toilet and retile my floor. I made a complaint to the AZ atty general and fortunately was reimbursed for the costs of the damages incurred to my bathroom. I was also informed that the plumber in question was laid off, but I'm still not comfortable returning to this company.

Excellent. Marty is friendly and super at doing a difficult job in a poor environment Trees, and desert broom he had to get through just to get there. He then gave me a very competitive estimate. He completed the work in less than 10 minutes. He also fixed my leaking valve and showed me how I could do it myself. I will definitely use Intelligent design in the future, and I'll request Marty. Great guy as well as a great plumber.

Gabe from Intelligent Design got to my house the same day and did the work. He was polite, professional and knowledgeable. Additionally, he came back to the house to help with my water softener that was clogging my lines with media resin. He didnt even charge me for the return call and spent about 45 mins clearing out the pipes for me.

I've had preventive maintenance plan (annual checks of AC and furnace) with Intelligent Design since 2015. During spring 2019 AC check, they found the refrigerant had all leaked out/coil rusted. Five days later, they installed new unit. The technicians were prompt and professional. New unit installed, checked out and up-and-running in four hours. Not even a speck of trash/debris left behind. Fantastic!!!!

These guys are really good. I'm and Engineer with HVAC experience. This firm is professional, punctual, talented, and knowledgeable. The HVAC mechanic effectively trouble-shot some complex heating and cooling symptoms. He corrected major control system wiring mistakes that were made by a different HVAC firm that originally and incorrectly installed the system in our new home. The trouble shooting preformed was methodical and was performed in a manner that was appropriate and effective. The repairs were timely and cost effective. I highly recommend this firm.

Hired to replace a failed AC unit. They only installed new units where they also sealed the ductwork, which added around $2500 to price. Their bid was the highest we received, but seemed like the quality/effort they put into it would be worth it. Just over two years later, however, the unit is leaking, and when I called, they said it was out of warranty and to "have just any other company go and fix it". I was shocked. We paid a premium, expected better service, frankly. Andrew is a great sales person, a bit high pressure, but it's obviously effective: I bit. He pitches a purportedly superior product and better installation. However, had I gone with a cheaper alternative (saving $6k-9k), that would've easily covered any repairs from another provider. Simply too much money and overrated for what you actually get. After installation of the new unit, I did not see any savings on my monthly utility bill over time.
