It's not difficult to buy a container load of air conditioners from a manufacturer in China and then pile 'em high and sell 'em cheap - the trouble is that you, the customer, can end up picking up the pieces when things go wrong. We have seen really cheap Chinese systems which prove the adage that all that glistens is not gold - for example offering warranties which have no backup so are worthless or having no parts supply available.We work with just two suppliers; Fujitsu, who have a strong world wide reputation and Martin Industries who have demonstrated a real commitment to customer support over the years that we have dealt with them. Buying an air conditioning system is not just about finding the lowest price ( though you'll struggle to beat ours!), but you need to know that the equipment comes with full support to provide years of trouble free service.
