A good appliance tech diagnoses the real failure, uses parts that keep your warranty intact when it matters, and tells you honestly when replace beats repair. Use these questions to separate factory-authorized shops and careful independents from “we’ll figure it out on site” vans that bill a trip fee and leave you with a dead fridge.
Why it matters: Washers, ranges, and refrigerators share brands but not parts or error codes. Ask them to confirm the model number from the tag (often inside the door or on the frame). Factory authorization can matter for in-warranty work and access to OEM parts — if they shrug at the model, keep calling.
Why it matters: Most shops charge a trip/diagnostic fee whether or not you proceed. Get the amount, what it covers (one appliance vs multiple), after-hours pricing, and whether the fee rolls into the repair total. Vague “depends when we get there” diagnostics are how small jobs become expensive surprises.
Why it matters: No honest tech can promise a final price over the phone for every failure, but experienced ones can name common causes (failed igniter, clogged drain pump, bad start relay) and ballpark parts + labor. You want ranges plus what would raise the price — sealed-system fridge work, control boards, hard-to-source panels.
Why it matters: Rules of thumb vary, but a careful tech will weigh age, parts cost vs unit value, energy use, and whether the same failure is likely to recur. Someone who never mentions replacement — or who pushes a new unit they also sell without explaining trade-offs — may not be optimizing for you.
Why it matters: Aftermarket parts can be fine for out-of-warranty machines; they can void coverage or fail fitment on others. Ask which parts they’d order, lead time, and whether they document serial numbers for warranty claims. Prefer written clarity before they order expensive boards or compressors.
Why it matters: Labor and parts warranties are often different lengths (for example 30–90 days labor, longer on parts). Ask what happens if the same symptom returns, who pays a second trip fee, and whether the warranty is transferable if you move. Get it in writing on the invoice.
Why it matters: Rules vary — some areas regulate appliance repair lightly, others require contractor or electrical licenses for certain hookups. Insurance matters if a tech floods a kitchen, scars a countertop, or damages a gas line while pulling a range. Ask for a certificate or carrier name you can verify.
Why it matters: Slide-in ranges, gas dryers, and built-in dishwashers involve shutoffs, flexible connectors, and sometimes permits or a second trade. Clarify whether hardwiring, gas leak checks, water lines, and leveling are included, or whether you’ll need a plumber or electrician on top of the repair bill.
Why it matters: A dead fridge or no-heat dryer is time-sensitive. Ask about same-week windows, whether the first visit is diagnose-only, and typical parts lead times. Shops that stock high-failure parts for major brands often finish in one visit; “order and hope” shops mean a second trip fee risk — confirm that policy.
Why it matters: Diagnostics sometimes uncover a second failure (bad board plus failed sensor). Agree that non-emergency parts orders need your OK with a written or texted estimate. Cash-only “trust me” pricing after the machine is in pieces is a classic homeowner trap.
Why it matters: Sometimes parts are obsolete or the sealed system isn’t worth opening. You still want a clear invoice for the diagnostic, notes on failure codes, and photos if useful for warranty or a replacement quote. Walking away with no paperwork wastes the fee you already paid.
