I own a restaurant in Mesa and I had my freezer go out. After calling a commercial equipment repair service, the repair guy they sent out told me it was the compressor was shot! However, I could tell he really didn't know. I think he knew too, because he called D and Del actually called me to see if I wanted him to take a look at it. Well after doing a thorough investigation, he found there were two parts that had blown and not the compressor. Saved me over $1000! I now use him to repair any kind of refrigeration or heating equipment I have in the restaurant. This guy knows what he is doing!
