Private preparation worksheet

Build a furnace service note

Record what you have noticed about your heating system, what you have had done before, and what you want to ask about. The notes stay in this browser tab and are only turned into a printable text file when you ask for one. This worksheet does not diagnose equipment, quote prices or recommend any technician.

This worksheet needs JavaScript

The service-notes builder runs entirely in your browser and needs scripting turned on to work. With scripting off, no fields will activate and nothing can be generated. You can still read the preparation guides on this site without JavaScript.

Your notes

All fields are optional. Leave anything blank you do not know. Nothing here is transmitted anywhere; there is no submission to any server.

System details and visit preparation

Furnace make or model (optional)

Copy this from the rating plate if it is easy to reach safely. Do not open panels or move anything to find it.

Serial number (optional)

Optional. Useful for a service record; skip it if you cannot read it comfortably.

Approximate system age in years (optional)

A whole number from 0 to 100. If you are unsure, leave it blank rather than guessing.

Most recent professional service (optional)

Month and year is enough. Format: YYYY-MM.

What have you noticed? (optional)

Describe sounds, smells, temperature changes or anything else you have observed from a safe distance. Do not attempt to inspect, open, or troubleshoot the equipment yourself. If you smell gas or your CO alarm sounds, leave the home and call for help from outside — see the official emergency sources listed in the guide.

Service history in brief (optional)

Earlier repairs, filter changes, or visits you want to remember. Keep it factual; no diagnosis needed.

Questions to ask (optional)

One question per line works well in the printed note.

Preferred visit window (optional)

For example: weekday mornings, or Saturday after 10am. This is a preference, not a booking.

How to reach you (optional)

Keep this minimal. Anything you type here appears in the downloaded file if you save it.

Before you write anything

If you smell gas, hear a hissing sound, or your carbon-monoxide alarm sounds, treat it as an emergency. Leave the home and call for help from outside. This site gathers emergency guidance only from official sources; see the CPSC carbon monoxide safety page and your local emergency instructions.
Do not open panels, disconnect vents, or attempt repairs to find information for this note.
This worksheet records your own observations and questions. It does not diagnose any system, estimate costs, or recommend a technician.
