What it is

A van-based service that finds leaks, replaces parts like hoses, condensers and compressors, and recharges A/C systems at the customer's location.

Your first three steps

  1. Study for and take the EPA Section 609 certification exam, which is offered by approved organizations and is usually online
  2. Price out recovery and recharge equipment for the refrigerants used in the cars in your area, and a used van or truck to carry it
  3. Contact used car lots, small delivery companies and local landscapers to offer a trial service, and list your business on Google Business Profile
Who pays

Commuters, busy households, small businesses with a few work vehicles, and used car dealers who want cars ready to sell.

How it makes money

A diagnostic fee, plus fixed prices for recharges and common repairs, with parts marked up. Small fleet clients can bring repeat work.

Skills that help
  • Automotive repair or A/C diagnostics
  • Reading pressure gauges and leak tests
  • Customer service and clear quotes
Watch out for
  • Check EPA Section 609 certification requirements and keep your records, since servicing vehicle A/C for pay generally requires it
  • Newer cars often use a different refrigerant that needs its own equipment, so check what your equipment can legally and safely handle
  • Check your state and city rules on refrigerant handling, mobile repair and business licenses
  • General liability insurance, and garage keepers or tools coverage if you hold customers' vehicles
  • Summer demand can be much stronger than winter, so plan cash flow
