“How long should it last?” That’s a question we ask when we buy pretty much anything. Below we provide some estimates of how some common household products should last. A few caveats:
- These are estimates and results can vary widely.
- To make sure you know when a product’s useful life may end, you need to know when it began. So save receipts and keep a record. On some items, such as your furnace or AC unit, you can actually tape the purchase date on the unit.
- If you don’t take care of the items (annual maintenance, cleaning, etc.), they won’t last as long.
