What Drives Price
Key factors include unit capacity and compatibility, drive method (air vs. liquid), and installation difficulty. A higher-capacity lower unit or a model with enhanced efficiency typically increases both parts and labor costs.
Regional Price Differences
Prices vary by market. In the Northeast, expect higher labor rates and permitting costs. The South generally features lower labor charges, with Midwest closer to the national average.
Labor, Hours & Rates
Labor costs rise with complexity and access. If replacement requires roof work, crawlspace access, or prolonged shutdowns, expect to reach the higher end of the range. Labor hours often range from 3 to 10 hours depending on site conditions.
Additional & Hidden Costs
Surprises may include extra gaskets, refrigerant recharge, or testing fees. Delivery surcharges and disposal fees can also affect the final bill. Hidden costs are more common when older systems lack standard connections.
