Cockroach infestation fries Fujitsu heat pump circuit board

This Fujitsu heat pump, installed at a rental property in Tauranga, was not working. The heat pump simply showed a fault code LED pattern on the indoor unit. Not much for us to go on!

An example of a low-cost, low quality heat pump

This is Daicool heat pump, (not to be confused with Daikin heat pumps, which are great). It was installed at a residential address in Tauranga. When it comes to heat pumps, as with most things, you get what you pay for. There is a big difference in a cheaper branded heat pump (in this case, Daicool) when compared to a quality brand such as Mitsubishi Electric, or Fujitsu.

This aging LG aircon unit kept slipping into fault mode

In the true spirit of fashion, this commercial air conditioning installation was a case of out with the old and in with the new! We were originally called to a commercial property in Papamoa's Fashion Island shopping complex, just as the very hot summer days rolled in, to inspect an ageing LG air conditioner which had stopped working. 


Diamond Air was called out to a Mt Maunganui, Bay of Plenty, property for a Mitsubishi heat pump repair recently. On inspection, we discovered that this 9-year-old GE50 Mitsubishi heat pump needed a new compressor and a new circuit board installed into the outside condenser.

The parts had failed due to their age and is to be expected as general wear and tear over time. Otherwise, the heat pump was in great condition – a testament to Mitsubishi Electic's superior technology and build quality. You can see the evidence of this is the photo gallery below.
