Common questions

What does an E1 or E4 error mean on a Samsung aircon in Dainfern Golf Estate?

E1 is a room temperature sensor error and E4 is an evaporator sensor error. Both are usually a failed thermistor or a connector that has corroded on the indoor board, and both are inexpensive parts once the correct one is identified.

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.
