My A/C went out on the hottest day of the year....104 in Oceanside! I took the car by to have Nate take a look. It was determined to be a defective Blower Motor. He ordered the part, and I was to return to the shop later that afternoon, after my business meeting. Upon my return, Nate said he would try to have the repair completed by 5:00 closing, but chances were they'd have to keep the car until the following morning. I waited in the waiting room for a few minutes, and then heard my name being called. Lou, the mechanic, was waving a piece of paper at me, and smiling. It turned out an invoice that had worked its way behind the glove box, had gotten stuck. Every time the A/C was turned on, it made a flapping noise, identical to a defective Blower Motor! We all had a good laugh! Thank goodness the stuck invoice was from a previous MASTERTECH repair! Nate & his crew have ALWAYS been extremely helpful, responsive, and very honest. You want a business with integrity? MASTERTECH is the place!
