Common questions

What does an E1 or E4 error mean on a Samsung aircon in Carlswald?

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 charge a callout fee?

A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
