HVACopedia
The field reference for HVAC technicians
Look up an error code, see what usually causes it and how to fix it, check the settings for the unit in front of you, and size the gas line, all from your phone on the job.
iPhone and Android apps are coming to the App Store and Google Play.
What's inside
We started HVACopedia for our own technicians, to stop digging through PDFs in a basement with one bar of signal. Here's what it does today.
Error codes and fix steps
Search by brand, model or code. Each code explains what it means, the usual causes and the steps to check, in plain language.
Settings and specs
DIP switches, jumpers and setup tables for common furnaces, boilers and tankless heaters, so you can set the board right the first time.
Gas calculators
CSST pipe sizing and gas meter clocking, worked out on the spot for natural gas and propane jobs in Canada.
AI assistant
Ask a troubleshooting question in your own words and get a starting point. Always confirm with the manual before you act.
Works offline
Download the library to your phone and keep using it in crawl spaces, mechanical rooms and new builds with no signal.
Field reports
Found a code that isn't listed, or a fix that worked when the book didn't? Send it in with a photo and help the next tech.
Built by people who do the work
HVACopedia comes out of a working HVAC company in the Greater Toronto Area. The content is written by licensed technicians in our own words, checked against the manufacturer's documentation, and updated when the field tells us something is missing.
