Air Conditioning Installation Pricing Guide*
When choosing a new air conditioning system, you can select from three performance tiers—Good, Better, and Best—priced as complete installations that include both the outdoor condenser and the indoor evaporator coil. The Good option ($7,500) features a reliable single-stage unit, the Better option ($10,500) upgrades to a quieter, two-stage system for improved humidity control, and the Best option ($14,000) provides a premium, variable-speed system for maximum efficiency and comfort.
If you prefer to replace only the outdoor condenser while keeping your existing indoor coil, you can deduct $1,000 from the Good tier or $2,000 from the Better and Best tiers, though replacing both components together is typically recommended to ensure peak performance and maintain manufacturer warranties.
