It’s the worst feeling in the world: your AC breaks down in the dead of summer, and the repair quote is enough to make you sweat even more. The biggest question we get from homeowners in this situation is, “Should I just fix it, or is it time to bite the bullet and replace the whole thing?”
We don’t want anyone to sell you on a brand-new system if you don’t actually need one. But we also don’t want you pouring thousands of dollars into a dying unit that’s just going to break again next month.
That’s why we’re giving you the exact tool we use to make the call: The $5,000 Rule Calculator.
It’s simple math that takes the emotion and the guesswork out of the decision:
Take the cost of the repair and multiply it by the age of your system.
If the result is less than $5,000, it usually makes financial sense to go ahead and repair it.
If the result is over $5,000, you are likely throwing good money after bad, and a new, energy-efficient install is the better long-term investment.
Example: A $1,200 repair on a 12-year-old system ($1,200 × 12 = $14,400). In this case, the math strongly leans toward replacement.
We built a free, interactive calculator right on our website so you can run your own numbers in seconds. We are here to give you the tools and the transparency you need to make the best, most informed decision for your home and your budget.
