Common questions

How much does AC replacement cost?
An AC replacement costs about $3,800 to $9,050 in the U.S. That covers a central AC outdoor unit and matching coil on existing ductwork. The range reflects parts, job difficulty and local labor rates.
Which states cost the most for AC replacement?
Labor is the part that changes by state. See the table on this page for each state's estimate.
How long does AC replacement take?
Today's Homeowner says you can expect a typical AC replacement to take between four and eight hours, including removing the old unit and installing the new one. Source
Can I replace a central AC myself?
Not the refrigerant work. EPA regulations require technicians who maintain, service or repair equipment that could release refrigerants to be certified. We recommend hiring a certified HVAC technician, and asking your local building department whether you need a permit. Source
Can I claim AC replacement on my taxes?
The IRS page says you can claim the Energy Efficient Home Improvement Credit, which listed central air conditioners, for improvements made through December 31, 2025, and it gives no later date. This is general information, not tax advice, so ask a tax professional about your situation. You can also check for state or utility programs. Source
