Daikin Split Inverter AC PCB Cost

[theterminator]

I’ve been advised Rs. 6500/- as cost of repair of 1.5 Ton Split Inverter purchased in 2019 (Out of warranty) for repairing of outdoor unit PCB by Daikin customer representatives. This is apart from the Rs. 600/- Visit charge.
Is it too costly or shall I go with it? Its in a tier II city.
