AC Repair or Replace Calculator: $5,000 Rule

This free AC repair or replace calculator from LiveFixPro applies the common $5,000 rule of thumb: multiply the age of the unit in years by the repair quote. Over 5,000 leans toward replacing, and 5,000 or under leans toward repairing. The $5,000 rule is a rule of thumb only.

It's made for homeowners weighing a repair quote, and it uses only the numbers you type. It asks for no personal details. It runs in your browser, and nothing you enter is uploaded or stored. A licensed HVAC technician should inspect the system and decide. This tool is not a diagnosis and not a quote.

What the calculator asks for

• Age of the unit, in whole years, from 0 to 60.

• Repair quote. The amount on the repair quote you were given.

• Replacement quote (optional). Add it to see the repair quote as a percentage of it.

What you get back

The tool multiplies the age by the repair quote and shows the working. It then tells you which way the rule of thumb leans: toward replacing if the result is over 5,000, or toward repairing if it is 5,000 or under. If you added a replacement quote, it also shows the repair quote as a percentage of the replacement quote. That is plain arithmetic and nothing more.

Use Copy, Download CSV or Print to take the result with you, and Clear to start again. If a field is blank, isn't a plain number or is out of range, the tool tells you what to fix. A replacement quote has to be above zero, or you can leave it blank.

An HVAC repair vs replace calculator, with limits

You may also see this idea called an HVAC repair vs replace calculator. The idea is the same: one common rule of thumb, applied to your numbers. It knows nothing about your unit's condition, your warranty or your plans, so it can't decide for you.

What about furnaces?

People often use the same rule of thumb for furnaces, with the same caveat. The calculator's labels talk about an AC unit and a repair quote, so treat any furnace result the same way: as one rule of thumb, not a decision. Ask a licensed technician about your furnace or air conditioner.

Questions to ask the technician

• What is wrong, and what does the repair include?

• Do any parts or labor have a warranty?

• Has this equipment been repaired before?

• What does the replacement quote include?

Before you decide

• Get the quotes in writing and compare what each one includes.

• Remember what the rule leaves out. Condition, warranty and your own plans are not part of it.

• Treat the result as one input. It is a rule of thumb, not a recommendation. Estimates only, not a forecast.

• Have a licensed HVAC technician inspect the system. They can look at the actual equipment.
