Daikin 5 year comprehensive warranty
So today after watching almost every video possible on YT I bought a Daikin FTKL 1.5 ton 3 star ac. I asked the sales executive about the claim of 5 years comprehensive warranty and was told that it covers gas refills. I live near a STP plant and due to moisture face corrosion issues every how and then. The sales executive told me that apart from spare parts the gas refill will also be covered albeit i have to have 2 services every year which will cost 750/- and i can get unlimited gas refill.

I want to ask those who have a 5 year warranty whether these claims hold any good. Also they told me to get an Anti corrosive liquid coating additionally for ₹1000 for future proofing the coils. I asked my local service guy and he told me to buy it from him at a reasonable price. Should i opt for it or do i get it done from Daikin service executives only.
