HVAC Replacement Opportunity Calculator
Weigh a system's age, repair history, warranty position and efficiency against the cost of replacing it, so a repair-or-replace conversation starts from arithmetic rather than a feeling.
Result
This is decision support, not a recommendation, and it cannot see the things that usually decide it: whether the customer plans to sell, what they can afford this month, whether the heat exchanger is cracked, and whether a technician has actually put eyes on the equipment. The age-times-repair heuristic is a rule of thumb the trade uses, not a law. Efficiency savings depend on your climate, rates and how the system is actually run. Use the customer's own bills rather than a brochure figure.

About this calculator
What is the age-times-repair rule?
Multiply the equipment's age in years by the cost of the repair. If the result exceeds the replacement cost, replacement is usually the better value. It is a rough heuristic, not a calculation. It ignores the customer's circumstances entirely.
Does old always mean replace?
No, and treating it that way costs you trust. A well-maintained twenty-year-old furnace with one cheap repair in front of it is often worth keeping. Age matters most when it appears alongside repeated repairs, rising spend and an expired warranty.
How should I present this to a customer?
As options with the numbers visible, not as a verdict. Show what the repair costs, what replacement costs, what the running-cost difference looks like, and let them decide. Customers who feel pushed into a replacement do not refer you.
