✅ What's Included in Window AC Installation

Wall opening measurement and sizing check
Angle frame fitting and secure wall mounting
Unit placement, levelling, and weatherproofing
Drainage slope alignment — prevents water leaking inside
Electrical connection and dedicated power point check
Leakage test around frame and wall seal
Full cooling performance test run before leaving

⚠ Why correct window AC installation matters in Kolkata: Most window AC installation complaints we see in Kolkata come from units installed by untrained handymen — wrong tilt angle causes water to drain inside instead of outside, loose wall sealing lets mosquitoes and rain in, and unstable mounting creates the rattling noise that gets worse every monsoon. Our technicians follow manufacturer specifications for every brand and wall type — including the lime plaster walls common in older South Kolkata buildings.
