The $5,000 HVAC Rule – A Method to Helping You Decide Between Repair & Replacement
If your air conditioner or furnace is acting up, you’re probably asking the age-old question: “Should I repair it or replace it?” One of the best tools to help guide this decision is something called the $5,000 Rule. It’s a simple formula that balances the cost of repairs with the age of your HVAC system.
What Is the $5,000 Rule?
The $5,000 Rule is an easy calculation to help you decide whether a repair makes financial sense.
Here’s how it works:
Multiply the age of your HVAC unit by the estimated cost of repairs.
If the result is more than $5,000, replacement might be the better option.
If it’s less than $5,000, a repair could be more cost-effective.
Example:
Let’s say your air conditioner is 12 years old and the repair quote is $450.
12 x $450 = $5,400
In this case, you might want to start thinking about a replacement.
Now let’s say your unit is only 5 years old and the repair is $600.
5 x $600 = $3,000
Repairing it would likely be the smarter move.
Why $5,000?
The $5,000 threshold isn’t just a random number. It’s based on the typical costs and lifespan of HVAC equipment. Most air conditioners and furnaces are designed to last 10 to 15 years, and repairs in the final years of a system’s life often don’t bring long-term value. This rule gives homeowners a way to think about those repairs in context.
When to Consider Replacement Over Repair
Even if the $5,000 Rule suggests a repair might be acceptable, there are other reasons you might still want to consider replacing your HVAC system:
- High energy bills – Older units are less efficient.
- Frequent breakdowns – Repeated repairs are costly and inconvenient.
- Inconsistent comfort – Hot or cold spots in the house may point to an aging system.
- Outdated refrigerant – If your AC still uses R-22 (Freon), repairs are more expensive and refrigerant is no longer available.
