What People Are Saying About Automotive Diagnostic Specialties
"Just got my 2005 Silverado A/C checked and repaired in less than 2 hours. Its been a long time since the cold air coming out the vents was that cold. This isn’t my first time to ADS. Every time they have fixed whichever vehicle I brought to them and it was done professionally with the cost estimate up front and accurate. I know when I leave I have a car that is fixed correctly and running much better than before. Good people to go to with your car problems!"

"It is my first time writing a review and I am writing this because I want to share how wonderful this place is! I have been going to this place for about 4 years for car repairs, tune ups, and oil changes. They are always polite and take their time to explain what is needed to be done and clearly list how much it will be. If I have any questions, I can always just ask and they will answer them right away. I am always satisfied with their work. Their waiting room and bathroom are very clean."
- Kynan K
"My Dad passed away which required me to make a road trip to Indiana. ADS went over my car with a fine tooth comb. They were nice enough to give me a ride home while my car was being serviced. I now feel safe to make the trip back to Dad’s which is a 1,700 mile drive. Thank you."

"In 2007 we moved to the Chandler area and needed to find a new auto service facility, ADS has been servicing our cars for eight years now and from the 15 year old pick up to the new Infinity and a car or two in between, we have had very good service. There have been needs on the pickup that they went above and beyond to find the problems. We have found the ADS team to be honest straight forward never once have I walked out the door thinking I was paying for a repair that wasn’t needed. I have and will continue to recommend their services."
- Sheila M
"Honest and reliable. I’ve been a customer for many years and am never disappointed. The staff is very knowledgable and explain everything. As a woman, unfamiliar with car mechanics, I trust ADS."
- Katie E
"ADS has once again gone above and beyond for me. I have been a customer since 2007. Each time I have needed service for my older Chevy Tahoe, ADS has been honest with regard to the work needed; prompt in doing the service; and always polite and respectful. I have recommended many people to ADS during the years and will confidently continue to do so in the future."
- Charmain B
“I have had numerous positive experiences with the service technicians at ADS, and wanted to inform others of their exemplary service. My A/C had lost the power to blow cold air into the car. I took the car back to the mechanic that installed the A/C a few years ago, since it carried a guarantee. After taking the car in week after week for an entire summer (no A/C is a very unpleasant situation in Phoenix!), the mechanic still couldn't (or wouldn't ) fix the problem. I regularly listen to KTAR, and enjoy how much I learn from the Bumper to Bumper Show. These guys have a list of preferred auto repair shops. I chose ADS, since it was the closest to my home. Ryan was the up front technician who greeted me, and has since cared for my car on successive visits. He had one of his techs, Jason, examine the car. He determined that the problem existed behind the dash, so to repair it, the dash would have to be removed, and it would take 4-5 days. He also gave me a $ estimate range. I was able to plan for this appointment, and have the repair completed. Ryan and my tech, Jason, treat me as if I'm their sister, mother, etc. Their recommendations are for my safety, not to make the company a profit. I travel quite frequently to Tucson, and there is a dead zone for cell phones on that stretch of road. I can't afford to be stranded . They let me know what needs to be done RIGHT NOW, and what can wait. A business that puts the customer's needs first, is one that will stay in business and succeed. This is a business that I will continue to patronize, as well as refer to my friends and acquaintances.”

"This is a follow-up to my email to you regarding ADS. I wanted you to know I was contacted by Greg and Ryan regarding my Toyota that would not start. They asked me to bring the car back. I did. They found that it was not an electrical problem after all. It had a bad battery (the battery was new from a diff. shop). ADS helped with the warranty even though they did not carry the brand. It was a happy ending. Thank you for your help. I love your talk show. Thank you for the good you bring to the public."
- Martha
"This is the best car repair shop I've found in the east valley. They are genuinely friendly, explain as much as you want, give you viable options and are accurate on estimates and completion time. All my work has been quality done and so far always fixed/addressed the issue the first time. I have never felt that they are "searching for things to fix" but they do bring up safety related issues with a recommended time to until it needs to be addressed. Overall just a great shop."
- Jim H.

"ADS has services my vehicles several times. This time, I asked the to look at a headlight for potential replacement and they proposed that they adjust the lamp alignment instead of replacement. My "pop-eye" light issue was fixed. Thanks to ADS for being honest and providing a lower cost service.

- Mark S
"Came in for a routine lube/oil/filter & tire rotation. Made an appointment. They had me in and out way ahead of promised time. Staff is always friendly, courteous and professional. Place is clean and exudes confidence to its customers. Only suggestion would be to get some more up-to-date magazines for the wait area."

"These guys are pros. They are honest, professional, positive, friendly, and they know what they are doing. They are a bit pricier than a few other options in the area, but you get what you pay for. I have learned over the years that if you want to keep your car in good shape, you need to give it the best quality service. These guys are the best."

"My brakes were feeling a little loose, so taking it in to ads i was sure i would hear bad news. and even for stuff i did not need. but i am happy they said all i needed was rear brakes adjusted and dome brake fluid. being retired and on a tight budget that was music to my ears..i recommend them to all my family and friends."
