Aberdeen doesn't ask much of an air conditioner

Summer afternoons here average 71°F. Most homes get by without cooling most of the year, and the units that are running aren't working hard to keep up. That's easy on the compressor and the coil, which see nowhere near the strain they'd see in a hotter place.

That doesn't mean a tune-up finds nothing. A unit that sits idle for long stretches can pick up problems that have nothing to do with heat. Refrigerant can leak slowly whether the system runs or not. A contactor can pit from age alone. A service visit checks the refrigerant charge, tests the electrical connections, and clears the coil and drain line so the system is ready on the few days it's actually needed.

Washington requires contractors to register with the state.

That registration puts the business on file with the Department of Labor and Industries. Nobody at the state tested this contractor's skill with an air conditioner or any other system. It means the state has a record of the business and who operates under that name, nothing more.

For a maintenance visit, the protection that matters comes from somewhere else. Anyone who opens the refrigerant side of your air conditioner, to check the charge or service the coil, has to hold EPA Section 608 certification. That is a federal requirement in every state, not something Washington adds on top, and it exists because refrigerant is regulated and handling it wrong is the real risk in this kind of work.

What does AC maintenance include?
A tune-up covers checking refrigerant levels, cleaning the condenser coil, checking electrical connections, and testing that the system cycles on and off the way it should. The contractor also checks the filter and airflow through the ducts. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, since that is a federal rule.
How often does an air conditioner need maintenance?
Most guidance calls for a yearly check before the cooling season starts. Aberdeen summer afternoons average 71°F, and homes here go without needing cooling most of the year, so the system sits idle for long stretches. A yearly check still matters because a system that has not run in months can have issues show up the first time it kicks on.
Is AC maintenance worth it?
Yes, because most cooling problems start small and get caught during a check before they leave you without cooling on the one stretch of hot days you get. In Aberdeen, where summer afternoons average 71°F, the system does not work hard most of the year, but a yearly check still catches worn parts or refrigerant issues early. A contractor can price the actual job for your system.
