Tacoma summers don't ask much of your AC

Summer afternoons here average 70°F. Most days you may not run the air conditioner at all, and some homes barely use it in a given year.

That light workload doesn't mean nothing happens to the unit. A compressor that sits unused for long stretches, then gets switched on during the few warm days, can stick or struggle to start. Refrigerant can leak slowly over a year whether the system runs or not, and a coil can collect dust just from sitting. A tune-up checks that the system will actually start and cool when you need it, on the handful of days that matter.

Washington requires contractors to register with the state.

Washington's registration puts the contractor's business on file with the Department of Labor and Industries. There is no trade exam behind it. The state records who is in business, but no one tests their skill at the trade before that number is issued.

For a maintenance visit on your air conditioner, what governs the actual work is federal. Any technician who opens the refrigerant side of the system, to check the charge or service the coil, must hold EPA Section 608 certification. That certification comes from the federal government, not the state, and it exists because handling refrigerant wrong is the dangerous part of the job. Washington's registration does not test for that. The federal certification is what stands behind it.

What does AC maintenance include?
A technician checks refrigerant charge, cleans the condenser coil, tests the capacitor, and inspects electrical connections. They also change or check the filter and look at the condensate drain for clogs. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the check always goes through someone qualified to handle it. The goal is catching a weak part before it fails on the first hot day.
How often does an air conditioner need maintenance?
Most manufacturers call for a checkup once a year, usually in spring before the cooling season starts. Tacoma summers stay mild, with afternoons averaging around 70°F, so the system here runs far less than it would somewhere hotter. That lighter workload does not remove the need for a yearly check. Dust and wear happen on the coil and electrical parts whether the unit runs hard or barely at all.
Is AC maintenance worth it?
Yes, because most compressor failures trace back to a problem that showed up months earlier and went unchecked. A yearly visit catches a weak capacitor or a dirty coil before either one takes the whole system down. In a place like Tacoma, where the air conditioner already runs light duty most of the year, sitting idle for long stretches without a check makes small issues easier to miss. A contractor can look at the specific system and tell you what shape it is in.
