Repair or replace?

Multiply the age of the system by the price of the repair. Over $5,000, it's time to compare with a replacement. Under that, a repair usually wins.

A 6-year-old furnace with a $700 inducer motor scores 4,200. Repair it. A 19-year-old air conditioner with a $2,100 coil scores 39,900. Get both prices. We put both on paper when you're close to the line.
