I called several other companies and Intelligent Design was the only company to answer. They had James come by and he provided excellent customer service. Very professional and provided me with lots of information to make a decision on the repair. Definitely recommend this company to anyone who wants a trustworthy and honest work completed on their home.

Air conditioner is three years old and purchased from Intelligent Design. Air Conditioner quit working on 7 June. Technician came out 8 June.Air conditioner working. Air conditioner stopped working on 14 June.Technician came out 15 June and says Air conditioner working. Worked for 3 1/2 hours. Air conditioner down. Will have to call tomorrow and request service to the Air Conditioner. This is most frustrating!

Honest and very nice, he told us everything and showed us the pictures of the problems. Very happy with the service and with Elmo, he is great! Bret was our sales person, listened to what we needed and gave us a good price on a new air conditioner. The installers were great, double checked everything they did and cleaned up after themselves, explained what they were doing and answered our questions. The over all experience was SUPER!We just had to have the blower fixed (6/13/21), in our old furance and Kage our service tech was great fixed it right away and now we have cool air. Thank you Kage, you are wonderful!!!!D. Norman

I am a repeat customer of Inteligent Design Air Conditioning. We were halving trouble getting our 2nd floor to cool. Elmo came with his assistant and assessed that there was a leak in the coil (?). while we had to wait a bit for the oart for repair to come from the manufacturer, Elmo found a temporary solution to use in the meantime. Scheduling all appointments were convenient and easy. I always find the office staff to be quite lovely. Elmo arrived promptly, was was very professional and friendly. He has serviced my ac and heating several times as we have a maintenance contract . I am just simply a big fan of this company! I highly recommend! And thank you Elmo!!

Eric Lawler, the Service Manager, actually responded to my call on the same day that I made the call. No other company could respond the same day! He immediately went to work and found that I had a bad compressor capacitor. He replaced that AND added a start-up kit, then washed down my coils for me (which no one had ever advised me to do regularly before). My house is now cooling down nicely! Eric offered me a 10-year maintenance plan, and with a 15 year old system, I jumped at the offer. They will check my system out twice a year, and the maintenance plan includes ALL kinds of other benefits. PLUS, he waived the cost of today's repairs with the purchase of the maintenance plan! We couldn't be happier, and when it's time to replace this system (probably sooner than later), we'll be contacting Eric again. That maintenance plan? It rolls over to our new system! Woohoo! Thank you, Intelligent Design!Didn't want to delete my previous review, but just had a (free) service call by Neal to make sure my system was up and running efficiently before we have to turn on the heat. This was a service that is included in the service plan I previously bought. Neal has only been with the company since April, but he knows his stuff, and he was super friendly. SO GLAD we found Intelligent Design! And when it's time for a new system, they will be the ONLY company we call!

He was very helpful and efficient and also explained things and offered help if I need it.Marty and his partner jetted out a very difficult drain pipe and did a great job getting my kitchen sink to work again. They were efficient, friendly and very competent in their procedures. And they cleaned up afterwards!

AC had a weird break, most systems worked except the part that actually cooled the house. Everything turned on, but no cold air (No it wasn't low Freon). Kage worked it for a short while checking all the components till he found the right fault and in no time flat my 95F house was back on it's way to comfort.

We just purchased a home that has a system installed by Intelligent Design. We got warnings on the thermostat that we were unfamiliar with so called to see if they could come out to check the system. They came out and checked everything and showed me how to change the filters. Very helpful and friendly. Great customer service.

Unit was installed Aug 2018. Rained during installation and installers were unprepared so water came inside the house, required four buckets to catch all dripping places.A few days later indoor humidity spiked from the usual 30% to 60%. Bread was molding, toilets dripping, atmosphere was clammy. I use an ecobee thermostat which records system state. During August with daily highs of 100-110 the report indicated the second stage compressor only ran a total of 8 hours. I have reported all this trying to convince them the unit is oversized. It is now November but so far they have not acknowledged their error. I fear we will be stuck with a terrible summer experience forever.First time we turned on heating unit in Nov there was no heat. Service person said the installers obviously never checked it because the gas valve was broken so could never have worked. A new one is on order but it has been five days now and we are still without heat, overnight lows are in the 40s and we are all getting ill from living in the cold. I understand parts can take time to procure but I can not understand why heating was not fully tested during installation.It is now Aug 2019, a year later. Last month they finally admitted the unit was oversized, they changed from 4 ton to 2.5 ton but would not refund me the difference in price. Unit ran almost constantly and could not cool below 76. Just received electric bill and it was highest ever living here 11 years. More service visits finally found another defective valve. Unit now does finally cool but humidity still always over 50%.So I give up. I chose this company because of outstanding reviews here. But I have had a poor experience and would not recommend them.——————-It is now May 2021. They have been out several more times since and FINALLY found a defective valve. Replaced and now humidity remains under 50 all the time. So they eventually did come through.

I was really impressed with the service that was done at my house by Intelligent Design Air Conditioning and Heating. Marty, the Service Tech, called me before he came to do the job and when he arrived he was very professional, knowledgeable, honest, and came with a whole lot of personality. I would highly recommend this company for your air conditioning and heating needs. Oh, and he also had a new sidekick with him also named Marty. They were both wonderful and I so enjoyed having them come to my house to inspect my hot water heater!

Marty Hudecek and his partner (also Marty!) came by our place to help us locate and address a leak that was making the house extremely difficult to stay in. Extremely professional, really easy to talk to, and clearly highly experienced. Before Marty we'd had four or five other people come out from various HVAC / plumbing companies who either 1) didn't spend much time diagnosing, or 2) didn't listen when we told them the patterns or contributing factors. Needless to say they all gave their answers and none of them solved the problem.Marty and Marty came over, did a very thorough investigation all through and under the house, listened to us, walked us through each step, and eventually discovered a tiny little automatic vent that had stopped working due to age. Marty explained how it was supposed to function, then showed me how it was no longer functioning properly--then directed me to a Lowes for an $8 solution to this problem (he was happy to install it himself, but was looking to save us money since it's an easy install). Compare that against the thousands of dollars of various repairs all the other guys had suggested, and Marty is our go-to-guy from now on.Putting in the vent was easy as anything, and as of right now seems to have solved the problem that nobody else was able to even identify. Rock on, Marty!

We have a service contract, and in addition to the covered annual sediment filter switch out on our Enviro system, we decided to switch out the carbon element a year early than the 7 year effectiveness. Living only half a mile south of downtown in Tucson, the hard water had used up the effectiveness of the carbon filter element and scale was building up on water fixtures after many years of seeing hardly any! We are healthy and happy with the Enviro system furnishing filtered water to our entire home.
