was worried that our reverse cycle AC system was behaving strangely anf I realised that I haven't had it professionally serviced since it was installed in 2010. I prefer to use locally located family businessed for all my trades jobs. ACI WA was passed to me with a glowing reference by another firm who didn't have any staff available. Suffice to say, ACI WA were on site within 24 hours; they serviced my system; and the assured me that the system was working well. What more could I ask for?
