How our repair process works
Five steps from your first call to the warranty receipt. No surprises.
- 1
Inspection
Your technician examines the appliance, listens to your description, and notes the model + serial for parts lookup. Visual + audio-based diagnostics first — non-invasive.
- 2
Diagnostics
Targeted tests on the failing subsystem (compressor, control board, heating element, motor, etc.) to identify the exact root cause. You get a clear explanation, not jargon.
- 3
Fix decision
Up-front estimate before any work begins: cost, parts, and the realistic likelihood of success vs. recommending replacement on an old or uneconomical unit. You decide.
- 4
Operational test
After the repair we run the appliance through its normal cycle on-site — never "it should work now, call us if it doesn't." You sign off when it's actually working.
- 5
Warranty + consultation
Receipt with warranty terms in writing. Plus a quick walkthrough of how to extend the appliance's life (filter cleaning, drain maintenance, etc.) — included free.
