After the AC repair was completed, wife went through the invoice and noticed that the tax charge was more than it supposed to be. After taking this matter up with the owner, he said that Banning tax rate is 8.25%, not 7.75%. I told him that it shows 7.75% when you check online. He said that few months ago he checked it was 8.25%. He called me back later and said that he contacted the city hall and they said it was 7.75%. Just wonder how long he has been over charging customers 8.25% even though it has been 7.75%. read more

This place has refused to work on my vehicles because of their age. He only wants to work on cars of a certain type and age...

Del knows his stuff. His estimates are always free and he's turned away work from me that he knows I can do myself. He advertises his shop as a Christian business and it's apparent he handles himself in a manner consistent with that. I've used him many times over the years and I always feel confident that my car will come out right. He's not the cheapest but I have never felt cheated going to him and that's important to me. All in all it is great value for the money considering the level of service you get. read more

Del is the most honest mechanic ever! My dad recommended him when I thought my car might be overheating. Took it to Mountain Air and Del did the free inspection and found nothing wrong. A lot of mechanics wouldn't have been so honest. I took my car there today after hitting a ladder on the freeway and Del was quick and efficient and more than fair price wise. I recommend him to everyone. He's a gem and you can't go wrong taking your vehicle there. read more

I just found Mountain Air's business card while cleaning out a desk. A number of years ago, I was on my way with my four children to go from the San Francisco Bay Area to Phoenix for my father's funeral, and had to get there that day because the funeral was the next morning. I had car problems and pulled off the freeway, and Providentially they were still open late Friday afternoon before a 3-day weekend. I had completely upset because I thought I wasn't going to make it, but they were very kind and reassuring, and a mechanic stayed late that night until my car was fixed so that I could make it to Phoenix. I have never forgotten their kindness, and I have a lot of respect for a company who will do that for a traveler in distress. read more

Can't stress enough what a great mechanic he is. Will always bring our vehicles to him. He is an honest Christian who obviously bases his business around that moral and ethical code. Summary: Del is honest, fair priced, stands by his estimate, may take longer than stated, overbooked, and yes sometimes grumpy but who isn't. read more

I am extremely happy with Del's service. Took my SSR in for a brake job and a check-up. He could have done all kinds of things to it but only did what he found necessary. He did only what was needed. I will always go back there. read more

I have been here quite a few times, and overall I am satisfied with the results. Other reviews say Del is honest, and I agree with that. Also, as said, he is not cheap, but not overpriced either. Once he gives you an estimate, that is what you will pay. Sometimes takes longer than stated, but not too bad, usually due to parts availability etc. As to customer service, sometimes they are very busy and not as friendly as other times, and I feel as though they get frazzled with too much work. After giving him 1000s of $$, I would have thought he'd remember me, but apparently not in terms of how he treats me sometimes. For major repairs, he will often buy things like engines and trans, and swap them out. This is warranty work and is quality, but expensive. I brought an Explorer with trans trouble, and he said no point in fixing, just replace it. He didn't look at it, or drive it, just no, an Explorer with over certain miles is shot, and that's it. I was not happy with that. So yeah, a few complaints...but why the 4 stars? Del is honest...for sure. Straightforward (maybe too much for me sometimes), reliable, and stands by his work. He is not out to overcharge or rip folks off. They do not try to sell you additional repairs or push anything on you. read more

Best mechanic you will ever run across/you will never find better mechanic!! Fair prices great job.

Fair, fast, and a very good mechanic. I will return for any work I need on my truck.Del takes care to diagnose the problem so the cost are in check. read more

Very true they are as good as it gets! Nice to finally have a place that only charges for the actual work performed. I've been coming here for over 20 years and won't take my old or new vehicles any other place! Plus they do it all, so no need to go to someone else for other types of work. Highly recommend! read more

I've taken 2 different vehicles to Mountain Air and have been very pleased with the results. Not cheap but what is these days. Del will give you a free estimate and that is the walk out the door price when he finishes the job. read more

Went this shop to have a wheel speed sensor installed. Del ( shop owner ) quoted me a set price of $ 75.00 ,which i thought was very reasonable. Work was scheduled on Friday 21 of December 2018 . Hours that day of operation were from 7:00 am to 2:00 pm. I had my vehicle there at 7:00 am sharp . Well I received a call from Del at approximately 10:30 am advising me that after some research my steering wheel column would have to be removed and then the steering sensor would have to be calibrated at a dealership. So , even knowing all this why wasn't the initial installation completed ? Was it that it was a holiday weekend...or was it a miscalculated qoute requiring more extensive work ? Non the less Del should have known better and not have wasted my time ! For a established repair shop ,I quess I expected more . I'll never consider a repair shop like this again, one that has several non operative vehicles in the parking lot , AGAIN SUCH A BIG DISAPPOINTMENT...STAY AWAY FROM THIS SO CALLED REPAIR SHOP ....ONLY GIVING THEM 1 STAR ...AND THAT IS FOR LOCATION ! read more

I've been going to Del for the past 15 years. I try to do my own repairs, but if I can't handle it or I just don't have time, Mt Air Auto gets the job done right. Del's prices are fair and the work is great, but what keeps me coming back is his honesty and professionalism. read more

We were traveling back to Arizona and went to a handful of shops where everyone was either "at lunch" or too busy to look at our truck. When we pulled up to Del's shop I for sure thought this was it, we're stranded in California. Del was honest and let us know he was slammed (the parking lot spoke for itself) however he was the ONLY one out of all places, that I KNEW was a genuine mechanic, when he asked "does it over heat when your at standstill or when you're driving?" He really cared!!! Not out for your money either!!! That's all we asked, was just for someone to give us their honest opinion! He was a life saver! Took 20 mins out of busy schedule to just take a peek at our truck and filled us up with water and guaranteed that we could make it home safely. Hands down, the best mechanic in banning California! Thanks again!! read more
