Flawless did an awesome job with my car. I hit them up to see if they were able to help me install some aftermarket parts, oem+ parts on my Type S and they were able to get me in, install coilovers, adjust my height, alignment, install my side skirts, diffuser, and the car has been looking amazing ever since! Great communication skills. Shout out them for the assist! Will be coming to them for any repairs needed for vehicle in the future!

Man I just gotta say , Flawless Works in Modesto really came through for me. They worked on my 2019 STI and I couldn’t be happier with how it turned out. The car hit exactly the wheel horsepower numbers they told me it would, which is honestly crazy accurate. They were super helpful the whole way through too. I ask a lot of questions and can get a little overwhelmed sometimes, but they took their time and explained everything without making me feel rushed. You can tell it’s a family-owned shop that actually cares about their work and their customers. Great people, outstanding work. Definitely recommend Flawless Works if you want your car done right 🔥

Took my car in for an alignment and they took care of me same day. No issues car drives great, and looks even better. They took my dad’s car in on short notice as well and provided an alignment along with a very detailed inspection which helped us pinpoint a lot of the cars soon to fail points. Really appreciate the team there!

I recently had my car serviced at Flawless Works and I couldn’t be happier with the experience. From start to finish, their team was professional, honest, and incredibly efficient. They took the time to explain exactly what my car needed and didn’t try to upsell anything unnecessary, which I really appreciated. The quality of their work truly lives up to their name—my car is running smoother than ever. The attention to detail and customer service made the whole process stress-free. It’s not always easy to find a shop you can trust, but I can confidently say I’ve found mine. Highly recommend Flawless Works to anyone looking for reliable and top-quality service!

Needed my transmission replaced for my Subaru Crosstrek 2018 CVT. Talked to Hector and got my transmission replaced for an affordable price. Hector was very helpful and took good care of me. I knew I was in good hands when I saw the other Subarus that they were working on. So they know subarus. If you drive a crosstrek and need a transmission for an affordable price this is the place to go. @Subietrekker

Frequently Asked About AC Repair

How often should my car's AC be recharged?

A properly sealed system never needs a recharge. If you’re losing cool air, you have a leak. We don’t just top it off — we find and fix the leak so you stay cool for years.

We strongly advise against it. DIY kits often overfill the system (causing compressor failure) and don’t fix leaks. Plus, modern R1234yf systems require specialized machines. Let us do it right the first time.

Simple recharges or filter swaps: 1–2 hours. Compressor or evaporator replacement: half to full day. We’ll give you a clear time estimate after diagnosis.

Yes — we have state-of-the-art recovery/recharge machines that handle both refrigerants. Whether you drive a 2005 Honda or a 2023 Subaru, we’ve got you covered.

Our AC performance check is $250-$599 and differ from manufacturer or model (call for current special). If you book a repair with us, we often apply the diagnosis fee toward the repair. Call (209) 672-2347 for upfront pricing.
