    AVOID THIS PLACE!!!!! I have gone to this place for two of my cars for a while now and Johnny Jr. always had no problem taking my money. In 2021 I had him install a brand new AC compressor which had been working fine ever since. On 8/14/2024 I had him install a new serpentine belt I brought him. On 9/3/2024 my AC compressor that has been working ever since he installed it blew out. I noticed on 9/7/2024 as I was doing my own oil change that the serpentine belt was damaged in a way that was only done by the mechanic and not by the compressor or any pulley's. The mechanic had issues installing the new belt and did not use the proper tools to install it as I was next to the car while he was working on it, he pried it on with a long tool that was not the correct tool to use like an idler pulley tension tool. I contacted Johnny trying to resolve the issue and on 9/8/2024 he tells me to come into his shop and he would refund me $100 not the total I was asking for $133.92 as I was asking him to cover the labor charged plus the cost of the belt I bought, he also told me after this not to come to his shop anymore and that he did not want to do business with me anymore. I went in to collect the $100 he said he would give me and he went back on his word saying he would not and that his shop is not responsible because it was my serpentine belt and not his. He asked me to explain to him why I was asking for a refund and I stated to him the following: I came in with a working AC compressor and just wanted you to install a new serpentine belt and two weeks later the compressor blows and there is damage to the serpentine belt from how the mechanic installed it. The compressor is not seized and did not damage the belt, nor are there any wobbly pulley's that could have done the damage to the belt. I am now out a working compressor and a serpentine belt because of all this. Before I knew the belt was bad, I bought a new AC compressor kit and was going to have him install it, he quoted me $180 for AC service and $195 to install the new compressor, he told me it would be $898 to install the drier filter and an additional labor cost for the expansion valve which he did not say the price for, he told me just to install the compressor since I have a lifetime warranty on it, if the compressor goes again then I can install the drier filter. So he wanted to charge me $1,273 without installing the expansion valve. He wanted me to take the chance and if the compressor blows, he would charge me again for another install and say I needed to install the drier filter and if that wasn't it then the expansion valve too. I called around and found a shop that would install the whole AC kit with compressor, drier filter and expansion valve for $450 not including Freon. They even will be installing a new serpentine belt for the same price of $450 since I had to buy another one after I noticed it was damaged by his mechanic. The point of this review is for his shop to understand that even though they are just charging for labor, if they damage anything, they are liable and that a customer should not be looked at as the culprit or guilty because they bring their own parts. His ultimate decision to not refund anything and only offer for me to bring in another serpentine belt and he would install it left me no choice but to leave a review here for others to see. legally his company is responsible to replace my compressor, I never asked him to do that and was going to have him install another one but after noticing the damaged serpentine belt and him going back on his word... This is the result and I am upset I even had to do this and waste my time. I will attach pictures later when I have more time.

    I had an issue with the A/C in my 2018 Honda Civic where the passenger side was blowing cold air…read morebut the driver side was blowing warm. After getting nowhere elsewhere, I brought it here and spoke directly with Mike. Mike actually took the time to listen to the symptoms and diagnose the problem instead of immediately trying to sell me expensive services I didn't need. They scanned the vehicle, found a B1235 code related to the driver side blend door actuator, and explained everything clearly. What impressed me most was the honesty. They diagnosed the actual issue and gave me a very fair price to fix it. No pressure, no upselling, and no guessing. Just straightforward, professional service. It's hard to find shops that value diagnosing the root cause instead of throwing parts or expensive services at a problem. Because of this experience, I am 100% going to recommend Mike and his shop to all of my friends and family. Thank you for being honest, knowledgeable, and treating customers the right way. Highly recommended.

    IF YOU CARE ABOUT YOUR CAR AND YOUR TIME DO NOT GO HERE !! I took my car in for a simple oil pan…read morereplacement and engine mounts. They failed to properly seal the oil pan twice and I had to take my car back 3 times! the second time they had used glue to seal the oil pan making a huge mess and voiding my warranty. Not only did it take them 3 attempts to finally reaper the oil pan they also over filled my engine oil by 2 and half quarts and the e fine mounts had to be replaced "again" cause it was quite obvious they never changed in the first place but charged me for it. Now my entire front suspension is compromised either due to them tampering or just the fact they had to drop my front suspension 3 times. Also their main tech isn't ASE certified and is just a "helper " AVOID THIS CHOP SHOP !!
