A standard split AC installation in Kolkata takes between 2 and 4 hours, depending on site conditions and piping length. Window AC installation is faster, usually 1 to 2 hours. Cassette AC and ductable AC installation can take a full day or longer because of ceiling work and ducting. One Point Solutions confirms exact timing during the site inspection before work begins.
Most homeowners booking AC installation in Kolkata want a straight answer to one question: how long will the technician actually be at my home. The answer depends on the AC type, the property, and how ready the site is before the technician arrives. Here is the full breakdown.
Average AC Installation Time by AC Type
Split AC installation: 2 to 4 hours. This is the most common AC installation in Kolkata homes and includes mounting the indoor unit, positioning the outdoor unit, piping, wiring, and drainage.
Window AC installation: 1 to 2 hours. Window AC installation is quicker since it does not require separate indoor and outdoor unit piping.
Cassette AC installation: Half a day to a full day. Cassette AC installation involves ceiling cutting and concealed ducting, which adds significant time compared to a standard split AC installation.
Ductable AC installation: One to several days. Ductable AC installation is typically done for larger homes or commercial spaces and involves designing and fitting a full duct network.
Tower AC installation for events: 2 to 6 hours depending on the venue size, since tower AC units used for weddings and banquet halls need to be positioned and tested across a wider area.
What Affects AC Installation Time in Kolkata
Distance between indoor and outdoor units. Longer copper piping runs take more time to fit and pressure test, especially in older Kolkata buildings where the ideal wall position for the outdoor unit is not always close to the indoor unit.
Floor level and access. Installing an outdoor unit on a higher floor or in a building without easy balcony access can add time for safety setup, common in apartment complexes across Salt Lake and New Town.
Wall type. Drilling through certain wall materials in older Kolkata homes takes longer than standard brick or concrete, particularly in independent houses in Behala and Garia.
Electrical readiness. If a dedicated power point is not already in place, wiring work adds to the total AC installation time.
Old AC removal. If an existing unit needs to be uninstalled first, this adds 30 to 45 minutes before new AC installation can begin.
Step-by-Step AC Installation Process With Time Estimates
Step 1: Site Inspection (15 to 20 minutes). The technician checks room size, wall structure, and the ideal placement for both indoor and outdoor units before any AC installation work starts.
Step 2: Mounting and Fitting (30 to 45 minutes). The indoor unit is mounted and the outdoor unit is positioned with proper spacing for ventilation.
Step 3: Piping, Wiring, and Drainage (45 minutes to 1.5 hours). This is usually the longest part of AC installation, since copper piping, electrical wiring, and drainage connections all need to meet safety standards.
Step 4: Vacuuming and Gas Charging (20 to 30 minutes). The system is vacuumed to remove moisture and air, then refrigerant levels are checked against manufacturer specifications.
Step 5: Final Testing (15 to 20 minutes). Cooling performance, airflow, and drainage are tested before the AC installation is marked complete.
Same-Day AC Installation Availability in Kolkata
Same-day AC installation is available in most areas of Kolkata, including Salt Lake, New Town, Behala, Garia, and Dum Dum, subject to technician availability. During peak summer months, booking a day or two in advance is recommended since AC installation demand rises sharply and same-day slots fill up faster.
How to Reduce AC Installation Time
Clear the area around the proposed indoor and outdoor unit locations before the technician arrives. Confirm a dedicated electrical point is available near the installation site. Have the AC unit and any accessories on-site before the scheduled appointment. Mention if an old AC unit needs removal when booking, so the technician arrives prepared.
