Duffy's Auto Service

Jan 17, 2025

5 Stars for Duffy's Auto. Bryan went above and 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. January 2025 update. I took my 2000 Excursion to Duffy's to fix the front suspension. After 187,000 miles it had lots of loud clunking over bumps and a bit of left and right wondering. Bryan fixed it to drive like it did 25 years ago: quiet with tight steering. Another 5 STAR job!

Duffy’s is my go-to spot in Denton for an honest and trustworthy mechanic. Bryan is top-notch—he keeps you fully informed with clear pictures and detailed explanations when diagnosing issues with your vehicle. His professionalism, fair pricing, and commitment to quality service are unmatched. I truly appreciate the great work he does, and I’ll definitely be returning for all my automotive needs.

This place is top notch. Bryan received a text from me around 9:00 at night back in August about my daughter’s car needing work done. It was her second week at college alone and I was traveling on business in Chicago and trying to manage getting the repair done over the phone. Bryan communicated with me via numerous calls and texts to work through the repair work that was needed. My best friend owns an auto shop but too far away so it’s nice to find someone local I can rely on to take care of my kid’s repair needs. I found Duffy’s because of good past reviews and Bryan and his team have lived up to my expectations.

It's hard to find an honest mechanic. Even harder to find an honest an proficient mechanic. Well if you are in the Denton area you can stop looking. Bryan and JT are your guys! My daughter is a college student in the area and is a 4 hour drive from me... so when she called the other day telling me that her car was overheating I got that pit in my stomach that a father gets when he has to send his daughter to a mechanic shop. I found Duffys on Google maps and read the great reviews... and let me tell y'all they are well earned. Bryan quoted a fair price, then unprompted kept looking and found us a better deal on the radiator fan that was bad... JT quickly and accurately diagnosed the issue and they had her back on the road the next day! Highly recommend!

Headline: The owner is the great car guy we all wish we knew. In addition to being incredibly knowledgeable and experienced, he’s honest, smart, considerate, very thorough and super friendly. Very decent human -will never take our cars anywhere else, now that I found him. (His staff is just as awesome - special shout out to JT…) Longer story: If having your F150’s brakes suddenly and completely fail (while driving at full highway speed) can ever end up being a net-positive thing, that’s where I am now. We had just had the brakes checked and rotors/pads replaced at a big chain auto place, so I was shocked when the brake fluid emergency alarm went off in the pickup. I tapped the brakes to check and my foot went straight to the floor. I had zero resistance. Managed to get the car stopped, and called AAA. They asked where I wanted the truck to be towed, so a quick Google search found me Duffy’s. Very nearby and great Google reviews. Duffy’s website says they work by appointment, and the best way to schedule is by text. I figured that would rule out a surprise AAA arrival. But, the reviews were so good, and I had about an hour before AAA got to me, so I thought I’d give them a text and see. Almost immediately, I heard back from Bryan, the owner. Very willing to help. So that’s how we found him. Turned out to be an unusual problem that Bryan and his guy JT quickly figured out - master cylinder and booster both had to be replaced. I had the truck back in 24 hours. Amazing communication from him the whole time, including video of the parts that failed, explaining exactly what went wrong. We were so happy to have found these guys, that when we drove to pickup the F150, we left the other car we drove up there in, just to have them go over it for us. (It was for due an oil change, and has just started a couple of other odd little things, so I asked them to do a full general checkup.) I expected to make an appointment for next week or whenever, but Bryan said we could go ahead and leave it right then. We’re here for good, now.

I can’t recommend this shop enough. I would have given them 10 stars if it was possible. My son goes to UNT and was having pretty serious issues with his Ford F150. Bryan asked us to bring it in and he would give us a free estimate. Well, the water pump decided to dump everything in the parking lot. Bryan did a thorough inspection and explained everything that was needed. I’m out of town and he went above and beyond not only with the repairs but he kept us up to date along the way. There was an issue with my Automotive repair credit card and he even worked with the credit card company and on his side to figure out the issues with that. He was very helpful and continued to say no problem we will figure it out. I am a 100% disabled veteran and unable to be there for my son but he helped me get this very stressful situation fixed and my son back on the road quickly. You don’t find that kind of service and attention to detail very often A huge thank you to Duffy’s auto service.

I’ll trust this place with anything I need done to my car! Bryan is a great guy and doesn’t beat around the bush, he tells you exactly what needs to be done with your car to be in safe working order again. Never been up charged here, just an honest guy ready to fix whatever needs fixing so you can get back on the road asap.

I’m so glad I found I finally found a great mechanic in Denton! Easily the best experience I’ve had. Bryan and JT are very great at that they do! They are extremely knowledgeable and fast at getting the work done. Bryan is great at communicating what needs done. My jeep was beyond loud when I took it in. Now it’s so quiet you can barely hear it run which is amazing. I can’t think them enough! If you need any work done please take it to Duffys!

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!

May 07, 2024

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.

Apr 07, 2024

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.

Mar 07, 2024

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.

Great service very knowledgeable does things right

Mar 07, 2024

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.

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!

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.

Feb 07, 2024

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.

Feb 07, 2024

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.

Feb 07, 2024

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.

Feb 07, 2024

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.

Feb 07, 2024

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!

Feb 07, 2024

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.

Feb 07, 2024

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!!

Feb 07, 2024

Just did an inspection here today. It was quick and the owner is friendly

Feb 07, 2024

One of the most honest mechanics I've ever used. He makes sure that you are replacing the correct part and not spending unnecessary money on things you don't need. I would highly recommend Duffy!

Feb 07, 2024

Our skid plate fell off in the first hour of our 13 hour drive - we found this place nearby and so glad we did!! Incredibly kind, quick, and helpful!

Feb 07, 2024

Replaced the condenser in my car extraordinarily quick and at a great rate! I will be back.

Feb 07, 2024

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.

Feb 07, 2024

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.

Feb 07, 2024

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!

Feb 07, 2024

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!!

Feb 07, 2023

Bryan and his tech are the only people I trust with our cars! They do great work and are always honest!

Feb 07, 2023

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.

Feb 07, 2023

Bryan is an honest and fair man.

Feb 07, 2023

Duffy's is the best if you want an honest, competent mechanic.

Feb 07, 2023

Great communication ! Thoroughly reviewed needed service with rationale and expected costs! It was completed and ready to go in a very short tine frame ! This is definately my new go to shop !

Feb 07, 2023

I cannot say enough good things about Bryan and his mechanic JT. They came to my sons rescue while he visited a buddy in Denton and his Toyota broke down. Fantastic communication and really prompt service. First class operation. If I lived in Denton I’d be a regular customer. Thank you guys 🙏🏻

Feb 07, 2023

I've used Duffy's for years and had nothing but the best service imaginable. They're honest, considerate, and reasonably priced. I recommend them without hesitation.
