What it is

A trade-focused web store or ordering service for HVAC parts and small equipment. Most orders ship straight from suppliers or from a small stock you keep at home or in a storage unit. You can add local drop-off for nearby contractors.

Your first three steps

  1. Apply for wholesale or drop-ship accounts with a few HVAC parts manufacturers and distributors
  2. Pick a narrow range, such as residential parts or mini-splits, and build a simple store with accurate model matching
  3. Contact local contractors to offer a trade account with quotes by text or email and fast delivery
Who pays

Small HVAC contractors, maintenance companies and landlords who want quick quotes and delivery to the job site.

How it makes money

Markup on parts bought through wholesale or drop-ship accounts, plus delivery fees and repeat trade accounts with set pricing.
