Duffy's Auto Service

I couldn't have asked for better service. If you are looking for a reliable, honest, and fairly priced mechanic, Duffy's is your place. I traded a handful of texts with Bryan; he sent me a quote, was flexible on appointment times and had my truck in and out in a half a day. Excellent service and even better customer service.

Going forward, I will only use them to service my vehicles. I would highly recommend them for your next automotive service needs as well.

Had a awesome experience with Duffy’s! Bryan got me in and had my car fixed in a days time. He was very knowledgeable and had great communication. I appreciated that he took the time to explain everything that was going on with my car. Very reasonable pricing as well. I will definitely be going to Duffy’s for all my car needs in the future.

Bryan and JT have worked on a few things on my cars. They’re honest and want to do what’s best for their customers. They definitely don’t try to do unnecessary work just to get a few extra dollars in their pockets.
Will definitely continue to bring them my cars.

Excellent service! I brought my car in for a flashing check engine and they looked at it right away and diagnosed the problem. Very informative and helpful will definitely return in the future!

These guys are the absolute best! They brought my Lexus GX 470 with 200,000 miles on it back to life! They are very professional and very easy to work with. Highly recommend.

Bryan is the best. He not only ensures high quality work, but also follows up with his customer on the experience after repair. He has saved me hundreds of bucks before by suggesting not going for maintenance repairs suggested by other places. He figures out the root cause and provides the best available solution. I provide my highest rating for this shop.

I have been using Duffys Automotive for 20 years and have always had a great experience. Bryan is very friendly and always ready to face whatever challenges you bring him. I recommend Duffy’s Automotive, a 5 star business.

Bryan at Duffy’s is a different mechanic than you are use to. He is upfront about what he can do for you and charges a very very fair price. On all the vehicles I have owned, I have always taken them to Duffy’s over the dealership that I purchased them from. I trust Bryan more than I would the dealership it came from. He has proven his knowledge, skill set, problem solving, dialogue and finding a solution many times to me.

If you truly are out to find that 1 mechanic that is honest, upfront and actually wants to help? Reach out to Bryan at Duffy’s.

There are few things in life as troubling as trying to find someone you can trust with repair/maintenance of your automobiles. Let's just say, typically, mechanics rank right up there with politicians and used car salesmen. The anxiety associated with a breakdown leaving you vulnerable to be taken advantage of is undeniable. That's where Bryan at Duffy's Auto Service breaks the stereotype. Great communication, not pushy with additional services, and so reasonably priced compared with the competition you begin to feel like it's you that is taking advantage. There's a reason Duffy's has a nearly perfect 5-Star Google rating, it is unquestionably earned.

5 Stars for Duffy's Auto. Bryan went above an beyond getting warranty service for the clutch in my son's car. The repair was completed in one day. While he replaced the clutch, he found and fixed some mistakes that Christian Brothers made last year.

Bryan is the best.

We were traveling on interstate, had a red engine light, pulled over, fluid on engine. Googled nearest place. Duffy’s Auto Service. Asked if someone could take minute and look. Guy said no problem. Looked it over identified problem, educated on us what to do and said we were safe to go. Great guy and service!! Thank you!!

Honest mechanics here. Good communication, good service, and good people. They've taken care of my family for years and we'll keep going back for all of our maintenance and repairs. Absolutely would recommend to others.

The mechanics at Duffy’s are honest, competent, and tenacious. JT has an old world work ethic and passion for perfection that is very hard to find anymore. He was able to correctly diagnose and repair a very complicated and involved issue I was having. JT took the extra time to tenaciously diagnose complication after complication. He even took the time to correct mistakes made by a previous mechanic. Bryan is an excellent communicator and kept me in the loop every step of the way. I cannot recommend Duffy’s enough. Their prices are more than fair, and the service is top notch all the way.

Very professional shop. Repairs are always on time, sometimes even ahead of schedule. Sometimes I even feel bad because Bryan seems to go out of his way to find the most cost effective way to get the needed repairs completely. It's well worth it just for the peace of mind and not having to feel like I've been ripped off when I get my car back. If you value honesty I would highly recommend the shop. Thank you Bryan!

Hands down the best customer service around! My radiator quit working while I was driving home and the owner went above and beyond to get me the help I needed. The repair was done in a timely manner and the price was phenomenal! I will definitely be coming back for all my car needs. Customer for life!

As a retired aircraft mechanic I’m very particular about who works on my vehicles, the staff at Duffy’s Auto Service in Denton checks all the boxes. Their knowledge, quality and thoroughness is top notch and they treated me with honesty and respect. I will not hesitate to return whenever the need arises.

I love Duffy’s!! Fast and very friendly!! They have always done a great job on my car and their prices are very reasonable! Highly recommend!!

Bryan at Duffy’s was incredible!! They were extremely prompt in communication and was very thorough in pricing for services. They made the chore of an oil change and inspection not feel like a hassle at all. I’ll definitely be back for any car maintenance.

Best mechanics in the area hands down. Bryan and JT have helped with all of my cars over the years from from my Buick Riviera and Cadillac Deville to my Chevy sonic they can do it all. They will work with you on every aspect price or finding parts or troubleshooting ideas. Hard to find honest mechanics these days so you would be doing yourself a service to go to Duffy’s.

2023 REVIEW:
If you live in the DFW area Duffy's Auto Service is the best place to go for any auto repair/car maintenance. Bryan has the most integrity of any working professional I've ever met. He works quickly and efficiently. His communication is leagues above anything I've experienced. He explains all of the services thoroughly. He sent me photos of the parts that were broken on my car compared to what they should look like, which was extremely helpful. If your funds are tight, he will break down your car's needs and let you know which things are a priority and which things can wait.
He will tell you when other professionals have overcharged you or quoted you for unnecessary services. When a AAA tow truck told him my car needed a new alternator he could have charged me for that expensive service, but instead he let me know it was just the battery that needed replacing. I can't recommend him enough!!!

Bryan is fantastic! I have never had a better experience with a business! I am a graduate student with limited funds. Bryan went out of his way to work with my schedule and ensure the repairs were necessary and the related components were in working condition as well. Great value, great service I will recommend this business to all of my friends and family!
