What is the $5000 AC rule?

The $5,000 rule is an industry accepted guideline that helps homeowners make a financial decision about their HVAC system. First, multiply the age of your system by the repair cost. If the outcome is over $5,000, you should probably replace. If the outcome is under $5,000, you should probably repair.
