Guys I need your suggestion regarding our Car AC system cleaning,The last time I asked my dealer if how much it will cost me to have my AC system clean is around 21k for general cleaning including those parts that base on them is need to be replace:

Filter/Receiver drier,Expansion valve/s

Kailangan ba talaga yon? I also called Denso Quezon Ave Hindi daw kailangan?

Price
Casa- PHP21,000(with parts need to be replace)
DENSO-PHP9,000(normal cleaning daw will do so no parts need to be replace)

Car details
Mileage-almost 25,000KM
YM-2012

Bat ang mahal ng cleaning ng APV? Innova 11k Lang SA casa?
