Common questions
What does an E1 or E4 error mean on a Samsung aircon in Montecasino Precinct?
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.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
Do you top up gas without finding the leak?
No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.
What does an annual service contract include?
Scheduled visits, priority response between visits, a written condition report per unit and fixed labour rates for the contract year.
