What is the step-by-step AC installation process homeowners should know?

The step-by-step AC installation process includes a professional assessment, correct system sizing, careful installation to manufacturer specifications, and full performance verification. Most standard installs finish in one day, with complex homes taking longer, and you’ll get a clear written estimate up front plus a 2-year warranty (4 years for Priority Plan members). We apply the same disciplined process for homes we serve around the Quincy area. One field truth: undersized or oversized equipment harms comfort more than the price tag suggests.

Here’s the step-by-step homeowners should expect:

• Home consultation and load calculation (square footage, insulation, windows, climate).
• Option review and system selection (central, ductless, or heat pump) with clear pricing.
• Customized installation plan and scheduling.
• Safe removal of old equipment and jobsite preparation.
• Installation to manufacturer specifications, including any needed ductwork adjustments and controls.
• Refrigerant, electrical, and airflow checks with startup testing.
• Thermostat setup, zoning configuration if applicable, and a customer walkthrough.
• Cleanup, documentation, and maintenance plan discussion.

Shut off power at the outdoor disconnect if asked by your installer and keep pets and children clear of work areas on installation day.
