Having a professional HVAC technician replace a damaged or leaking indoor evaporator coil typically costs between $900 and $2,300 total, combining the price of the replacement coil equipment and extensive labor. Replacing a coil is a complex, labor-intensive job because the technician must safely pump out and recover remaining refrigerant, disconnect rigid copper lines, braze the new coil into place with a torch, pressure-test the system for leaks, and recharge the unit with fresh freon. Verification: Obtain multiple written contractor quotes to compare warranty coverage and labor rates before approving coil replacement.
