Aj's Diagnostics Llc Auto &Truck Repair (Mobile Mechanic)Willis,New Waverly,Conroe

My car was overheating and was getting worse so I knew I had to deal with it sooner than later or the damage would be significant. I work in Willis so I searched around for the best repair shop I could find. I called AJ’s and they were able to evaluate my car and determined that the radiator had a leak and needed to be replaced. They were able to get the job done the same day. They even took me back to my job and picked me up when the car was ready. At the same time I noticed that my car was leaking oil pretty bad from my engine gaskets so they diagnosed it and got me a quote to get it fixed. I took it back the next week and they got all my gaskets replaced and replaced my spark plugs.They got my car running like it was brand new! Again, they picked me up when it was done. Yesterday my son

AJ and his team did a whole front end brake job and including ball joints on my motorhome. Honestly I wasn’t sure if anyone would be able to get it done because of the age of the vehicle. They made it happen and never left me hanging. While they were out at my place the fixed a broken bracket holding an alternator on my Toyota Yaris and change the blades on my dad’s riding lawn mower. I highly recommend!

I had an excellent experience with these people. My fuel filters on my diesel had plugged up and I can only go 30 miles an hour. They were willing to come to the parts store parking lot and do the job but I was only about a mile from their shop. The parts store had actually sold me the wrong parts and the lady there was able to get them to deliver the new correct parts and trade back the other ones. They cradle to graved though the whole operation. I was very happy with their working would it be happy to refer anyone to them. If they weren't so far away they would be my new go to mechanic...

When my truck would not start I searched for a mobile mechanic. I used one for years prior to moving so I was a little skeptical to find a trustworthy one here. I called Aj's. He came out and did a fantastic job. It turned out to be the trucks computer. I would not hesitate to call Aj's again. Very honest and knowledgeable.

After dodging calls and keeping my vehicle for over a month, I finally pulled it from him after learning he had lied about some work he had done for my father in law. He paid him to replace all the spark plugs. My father in law bought all the plugs, paid AJ for the labor. After he touched my father in laws truck, he had an issue with it missing while driving. Went to another mechanic and watched as he pulled the plugs out and only 4 out of 8 were new. My truck was in there for engine issues. When I finally pulled it from him, my ac blower motor was not working. Fully believe he used my truck parts on another persons vehicle. Avoid at all costs. 5 star reviews are paid for and he blocks any 1 stars. Here's hoping this makes it and helps someone.
