Common questions
Do you work inside gated estates?
Regularly. Technician details, ID numbers and vehicle registration are submitted to the HOA or gatehouse before the appointment so access is cleared in advance.
There is water on the floor under my ice machine, can you find the leak?
We trace it wet rather than guessing: inlet valve weep, split distribution tube, blocked machine drain or a backed-up bin drain all present the same way. The water side is pressure-tested before we recommission.
How urgent is a slow harvest cycle?
Treat it as urgent. A stalling harvest leaves the plate frozen solid, output collapses and the compressor runs against high head pressure, which is how a cheap solenoid fault turns into a compressor replacement.
How fast can you get to me?
Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
