Well i said this to the engineers when we started installing them.

These Inverter boards look expensive, change a compressor with the inverte board is going to cost rather alot of money.

And today saw our first Just out of warranty Daikin 410a 4 way blow scrapped.

Cost to replace compressor and inverter board £ 1,500.00 + VAT

Cost to scrap it and install a MHI cassette with a 5 year warranty £ 2,200.00 + VAT

You can guess which option the customer went for.
