You can hear a bad drain pump through a closed washer door. That was never the question. The question is whether the business around the repair holds together: whether you are legal to operate, insured against the one flooded laundry room, priced so a thirty-dollar part still pays for your hour, and organized enough to invoice before you drive away. Plenty of excellent appliance techs go broke in year one, and it is almost never because they could not fix the machine.
Appliance repair has a lower barrier to entry than HVAC or plumbing, which is exactly what makes the business side dangerous: the trade lets you start before you have thought it through. This is a practical, owner-to-owner walk through the 10 steps. One note up front: licensing, insurance and registration requirements vary a great deal by state and often by city, so treat everything here as the shape of the decision and verify specifics locally before you act.
Unlike HVAC or electrical, many states do not require a specific appliance repair license, and that surprises people into assuming there is nothing to do. There usually is. Depending on where you operate you may need a general business license or a home-occupation permit, a state sales-tax permit if you sell parts, and in some states a registration for anyone doing repairs on consumer goods. Check with your state and your city, because the city is often the one with the requirement.
There is one federal credential that matters: EPA Section 608 certification. The moment you work on a sealed refrigeration system, a refrigerator, a freezer, some ice machines, you are handling refrigerant, and you cannot legally buy or handle it without 608. Type I covers small appliances and is the common starting point. Without it, a large and profitable slice of the work is closed to you, so get it early.
Most solo appliance shops form an LLC. It separates your personal assets from the business, which matters in a trade where a mistake can flood a kitchen or start a fire in a dryer vent, and it is cheap and simple to maintain. An S-corp election may make sense later once profit is steady, but that is an accountant conversation with real numbers, not a day-one decision.
Then get an EIN from the IRS. Free, minutes online, and required for a business bank account. Do not run the company through your personal checking account. That single shortcut turns bookkeeping into a nightmare.
Add commercial auto for the van and a tools and inventory policy, because the parts riding around in your vehicle represent real money. Get quotes from an agent who writes for trades locally rather than guessing at coverage.
With the EIN, open a dedicated business checking account and run every dollar through it, with a business card for parts and fuel. When business and personal money never touch, the books nearly write themselves and you always know whether you are actually making money.
Appliance repair has a specific bookkeeping trap: parts inventory. You will buy parts that sit on the shelf, get returned, or never get used, and it is easy to lose track of what you have spent. Track parts against the jobs they went to from the first week, or your margin becomes a guess.
This is the biggest strategic choice in the trade, and new techs often drift into the wrong one:
Most successful independents use warranty work to survive the first months and then deliberately shift toward direct and property-manager work, because that is where the margin and the durable customer relationships live.
Manufacturer authorization lets you perform in-warranty repairs for a brand and buy certain parts you otherwise cannot get. It brings dispatched work and credibility. It also brings the brand's rates, their paperwork, and their scheduling expectations.
Treat it as a business decision, not a badge. Authorization for a brand that dominates your area can be worth it. Authorization for five brands you rarely see is administrative overhead that pays nothing. Pick based on what is actually installed in the homes around you.
Here is the trap unique to appliance repair. Your parts are often cheap, but your time and your truck are not. A twenty-two dollar drain pump does not mean a cheap job, because the job is the diagnosis, the drive, the disassembly and the warranty you carry on the fix.
Two rules keep you solvent. First, charge a real diagnostic or service call fee so a no-repair visit still pays; the logic is identical to the one in what to charge for a service call. Second, build a flat-rate price book for your most common repairs by appliance type: washer drain pump, dryer heating element, dishwasher control board, fridge defrost system, oven igniter. Price them once at your kitchen table, then quote them the same way every time instead of doing arithmetic in someone's laundry room.
And mark up parts. You sourced it, you fronted the cash, you carry the warranty. That is a service the customer is buying along with the part.
Parts availability decides whether you finish on the first trip, and first-trip completion decides your profitability more than almost anything else. Every return visit is a drive you do not get paid for.
Set up accounts with two or three parts distributors before you need them, learn which local supplier stocks what, and carry a small stock of the parts that fail constantly in your market. You are not trying to stock everything, you are trying to avoid a second trip on the twenty repairs you do most often.
The owners who make it can answer three questions instantly: what did I bill this month, what did it cost me, and how much is actually mine. In appliance repair the volume is high and the tickets are small, so a bad pricing assumption does not announce itself, it just quietly erases your year.
Track every job, every part against the job it went to, and your first-trip completion rate. That last number is the one most appliance owners never measure and the one that moves profit the most.
A solo appliance business needs three things and none of them is a dashboard to learn: a way to quote fast, a way to invoice on the spot, and a way to get paid. That is the gap FieldForge fills. You hold a button and say the job, for example "replaced the drain pump and cleaned the filter on a Whirlpool washer, one hour labor", and it builds a clean itemized invoice from your price book and texts the customer a link to pay by card before you leave. With ticket sizes this small and job counts this high, the fifteen minutes per job you would spend writing invoices at night is the difference between a business and a second job.
You are still the tech who can diagnose a washer by ear. You are just the one who also gets paid on time and knows exactly where the money went.
