What Los Altos homeowners say
Called about a warm freezer and got a three-hour arrival window the same day. Clear communication and they messaged before arriving. Made scheduling painless.
Responsive and accommodating with timing around my work schedule. The booking link was simple and the technician was on time. Easy from start to finish.
