The five numbers every homeowner should know

The HearthIQ TeamDec 5, 2025 · 5 min read

You don’t need to be handy to run a home well. You mostly need five small facts at your fingertips — the ones that turn a scramble into a two-minute fix.

The five to keep

Your HVAC filter size, your interior paint colors, where the main water shutoff is, your water heater’s model and age, and the breaker layout. Each is trivial to note and painful to be without.

Why these five

They’re the facts you need exactly when you’re least able to look them up — mid-leak, mid-repair, standing in a store aisle. Having them ready is the difference between a minor task and a lost afternoon.

Keep them in one place

Written on a scrap of paper, they get lost. Stored against the right item in HearthIQ, they’re a search away for you — or for whoever helps you fix things.
