Which appliance repair calls are yours: warranty, out of warranty or sealed-system?
Out-of-warranty work is the independent company's market, warranty work belongs to whoever the maker pays to do it, and any job that opens the refrigerant circuit needs a Section 608 certified technician. Knowing which of the three a search is likely to be tells us which pages to build and what to say on them.
Warranty and out of warranty. Under federal warranty law, as the Federal Trade Commission explains it, a warranty generally can't require the owner to use a particular company's service to keep coverage, unless that service is provided free under the warranty. Because a warranty repair is provided at no charge, the maker can require it to go through its own authorized servicers, and it can decline to cover damage caused by outside service. In practice: if you're in a maker's network, that work comes from the maker, not from search; if you're not, your market is appliances past their warranty, and your pages should say plainly which brands you service and that you work on out-of-warranty machines. This is a planning summary, not legal advice.
Sealed-system work. The US Environmental Protection Agency requires Section 608 certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerant, and since 2018 that includes appliances with most substitute refrigerants. Type I covers small appliances, which the federal rule defines as factory-sealed units holding five pounds of refrigerant or less, including household refrigerators and freezers, room air conditioners and dehumidifiers. Attaching gauges, adding or removing refrigerant or cutting the line counts as technician work; rewiring an external circuit or tightening bolts doesn't; the rule's test is whether the work could be expected to open the refrigerant circuit. The credential doesn't expire, and the card comes from an EPA-approved certifying organization, not from EPA itself. If your technicians hold it, we show it on your site and profile exactly as issued, because a sealed-system page without it invites the wrong calls.
