The old adage ‘You get what you pay for’ exists for a reason. The dearer units such Daikin are generally (not always) more efficient and or quieter. They also go together better and give you a better finished product. This translates to easier servicing should the need arise which in my opinion makes the additional purchase costs worth considering. However, some of the cheaper brands provide excellent value for money and offer very good performance. Final decisions should be based on specific unit performance and value for money. There is very little difference between the mainstream and top units sold these days. It’s only in the very cheap units that quality begins to suffer. Has anyone heard of the brand ‘Nobo’ which they say have the biggest residential portable air conditioner at 19,000 Btu.
