How long does AC installation take

Most central air conditioning installations take 6-12 hours for a standard replacement, or 1-2 full days for new installations with ductwork modifications.

The timeline depends on several factors. A straight replacement where you're swapping an old AC unit for a new one typically takes 6-8 hours. The technicians need to disconnect the old system, install the new outdoor condenser and indoor evaporator coil, connect refrigerant lines, and test the system. If your existing ductwork and electrical connections are in good shape, this is usually completed in one day.

New installations take longer, especially if ductwork modifications are needed. Adding ductwork, running new electrical circuits, or installing a new thermostat can extend the job to 8-12 hours or even two days. In Ottawa's older homes, technicians sometimes encounter challenges like upgrading electrical panels or working around existing plumbing and heating systems.

Weather and permits can also affect timing. In Ottawa's busy summer season (June-August), scheduling might take longer due to high demand. Most AC installations don't require permits, but if electrical work is needed, your contractor will handle the permit process with the City of Ottawa, which can add a day or two to the overall timeline.

Professional installation is crucial for proper refrigerant handling, electrical connections, and warranty coverage. Licensed technicians will also test the system thoroughly and walk you through operation and maintenance.

For a realistic timeline for your specific situation, it's best to have a licensed HVAC contractor assess your home and current setup. Want to discuss your AC installation needs? We can arrange a free consultation to provide accurate timelines and estimates.
