  • This company is totally professional and extremely attentive. We had multiple problems with both our refrigerator and freezer and the owner Joe was in constant communication and got the repairman here as quickly as possible. Great customer service from start to finish!

  • These guys are the epitome of professionals. I had a serious issue that they could have charged me good money to fix, but instead they gave me advice to work around it. For Sub Zero repair, I can’t imagine there is a better company. John is a master of his craft. A rarity these days.

He always addresses your issue immediately (makes an effort to come ASAP) and truly knows his stuff-and he’s incredibly neat to boot! Every service person, regardless of appliance, should take lessons from this man- he is beyond the best!
