Gratified with their service. I have contacted this Tap Air-conditioning and Maintenance Services for AC Installation, Maintenance and for Gas Filling. They have Quoted Me 1500 for Installation, Maintenance for 300 and 2200 for Gas Filling. I satisfied with their quotation. Two Technicians Came One For Installation and One for Maintenance and Gas Filling. They have done their work neatly given a good response to me so I am happy to get the service from this Center.
