The $5,000 rule is a popular HVAC industry guideline used to help homeowners decide whether to repair or replace an aging air conditioning unit. The formula involves multiplying the age of the equipment (in years) by the estimated cost of the current repair. If the resulting dollar figure exceeds $5,000, industry convention suggests that putting that money toward a brand-new system is generally more financially sensible than sinking funds into an aging, inefficient unit.
