What it is

A part-time service business for people who already hold the right trade qualification. You focus on furnace and boiler tune-ups, filter and thermostat jobs, and minor repairs, mostly in the fall before heating season.

Your first three steps

  1. Check your employment contract for rules on outside work and confirm your licence allows you to work for yourself in your province
  2. Buy your own test equipment and a stock of common parts, and get commercial general liability insurance
  3. Book a few tune-ups with neighbours and friends, then ask each customer for an online review
Who pays

Homeowners and small landlords who want a reliable local technician at a fair price.

How it makes money

Fixed-price tune-ups and hourly or flat-rate repairs, with repeat annual customers building a steady base.

Skills that help
  • Provincially recognized gas or heating trade qualification
  • Diagnosing common furnace and boiler faults
  • Reliable scheduling around another job
Watch out for
  • Gas and heating work is regulated, so check with your provincial regulator about whether you need your own contractor authorization or permits
  • Commercial general liability insurance, and check whether your employer's cover applies (it usually will not)
  • Possible conflict with your employer, so read your contract first
  • Demand is heavily seasonal, with emergency calls in cold snaps that may clash with your main job
  • Check whether your municipality requires a home-based business licence

Questions people ask

How much does it cost to start a furnace tune-up side business?

Estimates are typically around $2,000 to $10,000, depending on the tools, test equipment, insurance and vehicle setup you already have. If you already own much of your kit, you may sit toward the lower end.

How much can I earn from furnace tune-ups part time?

Monthly revenue is typically estimated at around $1,000 to $5,000, depending on how many hours you can give and how busy the season is. Demand is heavily seasonal, with the fall tune-up season usually the busiest.

What should I check before taking on heating jobs on the side?

Gas and heating work is regulated, so check with your provincial regulator about contractor authorization or permits. Also check commercial general liability insurance, whether your employer's cover applies, your employment contract, and any home-based business licence.
