So, I am occasionally asked about various cheap air con supply options advertised. I don’t do them. Another reason for this presented itself recently when I serviced a number of units for a PMB company, one of which was a “grey” Chinese make and which needed a replacement pc board. To cut a long story short, after exhaustive inquiry through trade connections and on-line, I could not contact a local supplier. I am, however receiving quotations daily for supply of every other conceivable type of air con equipment from Chinese mainland companies!
I only recommend well-known makes supported by Nation-wide wholesalers.
