Steps
Confirm technician EPA 608 certification level matches the refrigerant and charge size involved (see Type I for small hermetic appliances)
Verify you have the required equipment on hand: recovery machine, vacuum pump, brazing setup, and refrigerant charging scale appropriate to the refrigerant type (including A2L- or hydrocarbon-rated equipment if applicable)
Estimate the job margin: sealed-system repairs (compressor, evaporator, condenser, capillary tube) take significantly longer and carry higher failure/comeback risk than component-level repairs, so price and time-budget accordingly
Weigh the age and remaining value of the appliance against sealed-system repair cost — many shops set an internal threshold where they recommend replacement instead
If turning down a job, refer the customer to a shop that specializes in sealed-system work rather than attempting it without the right certification/equipment
Known gotchas
Sealed-system work on flammable refrigerants (R-600a) or mildly flammable A2Ls (R-454B/R-32) requires additional safety equipment and training beyond baseline EPA 608 certification — treat this as a separate go/no-go decision, not just a certification checkbox
Comeback risk is higher on sealed-system repairs; factor warranty/callback costs into the price rather than quoting it like a simple parts-swap job
This is a business/operations judgment call, not a fixed regulatory rule — avoid presenting any specific margin threshold as an industry standard, since shops vary widely
