Legal Setup and the Refrigerant Line

The legal baseline for appliance repair is lighter than most trades, with one federal exception that bites anyone who opens a refrigeration system. Walk the setup in order and none of it takes more than a week.

The baseline: entity, registration, bank

Washers, dryers, ovens, dishwashers: most appliance repairs require no trade license anywhere in the United States. What every operator needs is the standard business skeleton. Form an LLC or file a sole proprietorship with your state; the LLC costs a filing fee and annual upkeep but separates your personal assets from a business claim, and in a business where you disconnect water lines in strangers' kitchens, that separation is worth the paperwork. Get an EIN from the IRS, which is free and takes minutes online. Open a business bank account. Register for any general business license your city or county requires.

Then check your specific location against the handful of places with appliance-specific rules. California requires an Electronic and Appliance Repair Dealer registration with the Bureau of Household Goods and Services, a business registration rather than a technician exam. New York City requires an Electronic and Home Appliance Service Dealer license. A few other states regulate through contractor or electrical licensing when work touches wiring or gas. The check takes one phone call to your state consumer affairs office or a search of your state name plus "appliance repair license," and it is the only jurisdiction research this business demands.

Insurance: the policy that earns its keep

General liability insurance is the one coverage you buy before the first job, not after. Benchmarks for small trade businesses run roughly $35 to $55 a month at the low end and average $81 a month on the higher side, depending on limits, state, and revenue. In this trade the realistic claims are not dramatic: a scratched hardwood floor under a dragged dryer, a water line that weeps after a reconnection, a countertop chipped by a dropped panel. A single flooring claim can exceed a year of premiums, and customers increasingly ask for proof of insurance before booking. Operators in the r/appliancerepair thread suggest carrying high limits, on the order of $1M to $2M, which is the standard structure of small-trade policies anyway, and the incremental premium is small once a policy exists.

The refrigerant line

Here is the federal rule that shapes your service menu. Under Section 608 of the Clean Air Act, technicians who maintain, service, repair, or dispose of equipment containing refrigerant must hold EPA Section 608 certification. Household refrigerators and freezers are small appliances under the rule, meaning machines with less than five pounds of refrigerant, and the matching credential is Type I, which is offered as an open-book online test costing roughly $10 to $25.

What that means in practice: the enormous range of refrigerator repairs never opens the sealed system at all. Defrost systems, fans, thermostats, control boards, door gaskets, drains, ice makers: none of it requires certification. The moment work touches refrigerant itself, whether that is compressor replacement, leak repair, or recharging, you need the certification, and for anything beyond basic Type I work you need the recovery equipment and the brazing skill that sealed-system work demands. Many successful operators hold Type I for the flexibility and still refer most sealed-system jobs to refrigeration specialists, because the equipment investment and the liability do not pay for themselves at low volume.

Gas: know the shutoff, respect the line

Gas ranges and ovens add a second boundary. Checking an igniter, a flame sensor, or an oven valve with the appliance's own gas shutoff closed is normal appliance work. Modifying or extending the gas supply line behind the appliance is plumbing work that many states license separately, and a mistake is not a callback, it is an emergency. Gas procedures get their own detailed treatment later in the course. The legal point is simpler: your menu includes the machine, not the building's gas infrastructure.

Setup complete, the question that decides whether any of this pencil holds is the money math: what calls pay, what your time actually earns, and the two-visit structure that quietly eats beginners.
