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.
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.
Is a compressor replacement guaranteed?
Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.
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.
