Home maintenance tools for the expensive appliances in your house

Enter your appliance’s serial number and we’ll tell you exactly how old it is. Then you can compare that against typical lifespan and replacement cost to decide whether to repair it or replace it.

We also have calculators for maintenance budgeting and filter sizing, and plain guides to the parts of your house most likely to fail.

Tools

Enter your own numbers — a serial number, a repair quote, a filter size — and get an instant answer.

By appliance

The same calculator, one appliance at a time — each page also shows exactly where to find the serial number on it.

What they last, and what they cost to replace

Lifespans are ranges because usage, maintenance and install quality all affect them. Replacement figures are estimated cost for a mid-range unit, including installation.

Something just broke and I need to decide.

Get the age first, then enter the repair quote — the calculator compares repair vs. replace by cost per remaining year of life.

My hot water is unreliable.

Water heaters are the one appliance that fails destructively, by leaking rather than just stopping. Check its age now, before it fails on its own.

I do not know what size filter to buy.

Measure the slot, get the nominal size, and see what MERV suits the system.

Our own appliance-age lookup data shows 80% of confirmed refrigerator checks involve units already 10+ years old — and washing machines break the pattern entirely. Read the findings →
