Common questions

Why is ice building up at the back of my Defy fridge in Steyn City?

That is almost always a defrost circuit failure: the heater, bimetal or defrost sensor. The ice blocks the evaporator, airflow drops and the fridge compartment warms up while the compressor runs constantly.

What temperature and humidity should a wine cellar hold?

Twelve to fourteen degrees Celsius at 60 to 70 percent relative humidity. Drift outside that band usually means a failed humidistat, a leaking vapour barrier or a unit sized for a smaller cellar.

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.
