Sad

Howard is a great mechanic.

Awesome service. Radiator repaired as quoted.

The best service and most knowledgeable, honest shop around.

Worked on the classic, and kept me informed the whole way. Will use them again

Very friendly, stand behind their work
You just don't find service like this anymore.

These guys know their stuff. Go on there and forget about it. Their prices are competitive.

Best radiator and fuel tank service in tbe Bay Area.

Refused to work on my AC if it involoved the evap unit behind dash... useless!

Great service, boiled my gas tank for a reasonable price. I will definitely do business with them in the future!

A+, 100%, Perfecto. These guys are an anomaly for this area in 2019. They did everythng they said they would, when the said they would and charged a fair price worthy of their talents. Spoiler alert: these guy are REAL mechanics. Nice to see they still exist in our modern app this and app that society. Thanks Bill and Calvin, et al.

I went here to have some reduced beadlock fittings crimped. Nobody else in the area had the tools to crimp reduced beadlock. They crimped the lines while I waited, and even let me watch. Great service and fair price!

ONE OF THE LAST TRIED AND TRUE AUTO AND AIR.CONDITIONING SPECIALISTS. I DROVE FROM GILROY JUST TO MAKE SURE I WOULD GET THE RIGHT CUSTOMER service AND NOT GET RIPPED OFF.. I COULD NOT HAVE BEEN ANY HAPPIER.. WHO DOES THIS THESE DAYS? ONLY HOWARD AVE.Radiator service. They specialize in the older great models you see in car clubs. Please Please don't ever change!!

Still serving San Mateo County as #1 in field of business glad too see him and sons every time . Best work available for rebuilding radiators, and air conditioning work for your vehicle

Blown away by their capability! Fixed my AC that was given up for dead for nearly 10 years. Fixed it in 2 hours after multiple shops said it was not worth fixing a broken AC on a 2001 Chevy Suburban stating the fix would cost more than the truck was worth. Howard Ave fixed it for the cost of one “O” ring =$18.00.

Dropped off an old worn out radiator from by Sunbeam Tiger resto project. The staff were friendly and kept me informed on the scope of the job. Picked up a beautifully refurbished radiator; I could hardly recognize it. Can't wait to drop it in my car!

These guys are the masters! They can repair pretty much any radiator fast and cheap. Sometimes there's a problem later but that's unavoidable in the automotive industry and these guys do their best to be very thorough. 5 stars, thumbs up, love these guys! Great old school atmosphere too!

These gentlemen are very honest! AC was not blowing out cool air in my 2004 VW Passat, so I asked Bill to check whether the Freon was low. It turned out the Freon level was OK, but the electronic(s) needed attention from VW dealership. They only charged a extremely low price for their service. I am thankful.

'92 GMC Suburban (now 200,000 miles and still going strong) with busted radiator; they enstalled a new one in a couple of hours. Price was fair, staff was nice. Radiator still fully functional 100%... that was four years ago! Now my heater core has plugged up. I'm going back to them; and I live in San Jose! :)
