What this project involves

Replacing an air conditioning system covers the outdoor condenser, the indoor coil or air handler, line set and electrical connections, refrigerant charging, startup and commissioning. Efficiency level, tonnage and ductwork condition drive most of the difference. Estimt builds a preliminary planning range, then routes your project to local HVAC professionals.

AI estimates are preliminary planning ranges, not binding contractor quotes. Actual costs may change after professional inspection based on project scope, materials, permits, access, local requirements, and hidden conditions.

What changes the price

  • System size

    Tonnage is matched to your home, not just the old unit's label.

  • Efficiency rating

    Higher-SEER and variable-speed equipment costs more up front.

  • Ductwork

    Leaky or undersized ducts may need sealing or resizing.

  • Electrical capacity

    Some installs need a new circuit, disconnect or panel work.

  • Permits and rebates

    Permits are typical; utility rebates may offset part of the cost.
