Elmo is the reason I have stayed with this company for over 6 years. The company is wonderful but Elmo is just the best. They do not try to force repairs or sales but they do give you the option. I always feel better when they come to give my heating and air a time up and repair.

My service technician Jordan Oliver was outstanding and really went the extra mile to get our ac back up and running. He was highly professional, explained the problems so we could understand and even got us a portable ac unit to use while we waited for parts. The company as a whole was excellent in all aspects. I highly recommend them.

In addition to replacing my water heater, Marty installed a whole house water filtration system and was willing to do so in a more difficult way that satisfied my preference. He is knowledgeable, professional and helpful. He was happy to take the time to answer all of my questions

Technician Jordan (I think that was his name) treated us amazingly in checking our AC unit for problems. The first thing he saw when we looked at the unit was an accessory another local company had installed a few years ago and the same company had serviced the unit 1.5 months before. Jordan saw it and immediately told me there was a recall on the piece (it could catch fire). The company that installed it never even called, nor mentioned they needed to remove the piece when they were out just a few weeks earlier. I'm so thankful previous company couldn't make it out same day, and that I called Intelligent Design AC and plumbing. I already felt so much better knowing that Jordan knew his stuff, and checked everything he could to make sure our unit worked properly. I also greatly appreciated the photos on our invoice of Jordan's progress checks on our invoice. This is a great company! Give them a call!

We wanted to get an all home water softener /treatment system and had heard of the enviro system which they install. We called and they came out to talk to us about it, we decided to have it installed and they came out in very short time. Marty and his team of installers installed with minimal downtime without water. The work area was cleaned up- you wouldn’t have known anyone was here! We will definitely use Intelligent Design Air Conditioning and Plumbing again! Very reasonable too.

Everyone I have had the pleasure of interacting with at Intelligent design are great, professional and customer oriented. Emily at the office is always amazing to help answer the many questions I've had or get me the right person to talk to. The technicians installed the Amana unit beautifully and when above and beyond. The sales person spent so much time with me and answered all my questions. Paul and Amy were sure to register the warranty and get copies to me and make sure everything was done correctly. Tenea was an thourough technician and explained everything on how to change and care for filters to the reasons for maintanence and what they do. I really appreciated the time this company spent on gaining my confidence. My heating bill is a third of what was with my older unit to boot! Thank you everyone at Intelligent Design!

I purchased “The Big Deal” from Angie’s List on June 24. The deal was for air conditioning inspection, cleaning and tune-up. I chose this deal with Intelligent Design based on their history on Angie’s List.The appointment, for June 30 – 8 to 11 window, was set up the same day.The service tech called to let me know he would be at my home in about 15 minutes. (I also received a reminder call the day before.) The condition of the van and service uniform told me that this was a professional company. The tech introduced himself, Efrain, and I showed him the location of the unit.After asking me a few questions, he went right to work. When the inspection was completed, he advised me of what he had found and gave me an estimate of what the work would cost. He also talked to me about the service plans the company hand and gave me some information to look at while he proceeded to do repairs.I was very impressed with Efrain’s knowledge and friendly manner. I decided to purchase a service plan – I felt confident that this was the company I was looking for to service my unit. Intelligent Design also does plumbing, air duct cleaning and installation of new units. I look forward to working with them in the future to service my home.June 2021I called Intelligent Design because my A/C was not cooling. I got a call back from Tech Elmo Acosta and explained my situation. He arrived within an hour and quickly went to work. He found the problem and made his recommendations. Elmo is definitely a 5-Star Tech. He is professional, knowledgeable and friendly. Within an hour he had the air cooling. Buddy and I are grateful for his efficiency and easy to talk with manner. Thanks again ID for having such great employees.

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!

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.
