What Our Customers Say
Real reviews from homeowners across Marin County
"Our Sub-Zero 642 was running warm. UniFix diagnosed a failed evaporator fan motor and replaced it the same day. Temperature has been perfect since."
"The ice maker in our Sub-Zero stopped producing after 8 years. UniFix fixed it in a single visit. They clearly understand these refrigerators inside and out."
"Had three other companies look at our Sub-Zero PRO 48 with no luck. UniFix found the actual problem on the first visit and fixed it. Should have called them first."
