1. Inventory the dates
Write the appliance, approximate install year, last service date, and one symptom. “Unknown” is better than a guessed date.

Build a Home Maintenance Calendar From the Appliances You Already Own
Turn appliance ages, recent repairs, and one move-in date into a calendar that distinguishes a filter reminder from a real safety check — without buying a home-management subscription.

What this replaces
uses appliance age and last-service dates to expose the next decision window, rather than printing a flat list of chores for every home. The result is a small object you can inspect: it carries a count, a context row, and a next action instead of asking you to trust a paragraph.
Tool note. This workflow uses ChatGPT Free. ChatGPT’s official product pages and help material were checked on September 12, 2026. The guide treats free access and limits as account-dependent rather than promising a quota. Runners-up were a generic chore board (no age logic) and a paid home-maintenance subscription (unnecessary for the core calendar). Use sample data first, then decide what information you are comfortable sending to an external AI tool.
The handoff
2. Ask for a maintenance ledger
Have ChatGPT return JSON with item, interval_days, next_check, reason, owner, and stop_condition. Tell it not to invent manufacturer intervals; flag those for the manual.
3. Sanity-check the card
Compare safety-critical intervals with the appliance manual and a licensed technician’s advice. Then use the local card to keep the next 90 days visible.
Prompt shape for the external tool: return only JSON in this form — {"heading":"…","metric":"…","rows":[{"label":"…","detail":"…","value":"…"}],"next":"…"}. The companion app below uses the same visible result shape locally and makes no AI request.
Try the manual board
Load a sample, replace it with your own notes, and inspect the generated object. Sample values are illustrative, not verified facts.

What breaks first
Every task becomes urgent
Add a stop-condition and sort by safety, cost, then convenience.
The model invents a manufacturer rule
Require a “source needed” flag and check the actual manual.
The calendar becomes another forgotten list
Tie each row to a real date and a person who can complete it.
Boundary. Household organizer only: it does not inspect equipment, diagnose a fault, or replace a manufacturer manual or licensed professional. Stop using unsafe equipment and contact a qualified technician when there is gas, electrical, structural, or water damage risk.
Go deeper without losing the free path
The free board is complete on purpose. The companion app adds a tangible file, history, or handoff only after the result is useful: a printable seasonal packet and local maintenance history; 9 rows × about 2 minutes of reformatting = roughly 18 minutes avoided each season
