Cooling season is short here, but storms still take their toll
Summer afternoons in Longview average 74°F. That is mild, and it is part of why an air conditioner here can sit unused for long stretches between the days it actually runs.
A unit that idles most of the year still sits outside through wind and hail. Cowlitz County has recorded damaging wind five times over the past ten years, and a hailstone as large as a quarter once. A tune-up is when a contractor checks the coil fins and cabinet for that kind of damage, so a bent fin or a loose panel gets found before the next hot afternoon asks the unit to work.

Washington requires contractors to register with the state.
The registration puts the business on file with the Department of Labor and Industries and confirms it carries the bond and insurance the state requires. It does not mean anyone was tested on the trade. There is no state exam behind the number on the truck.
For a maintenance visit on an air conditioner, the protection that actually matters comes from elsewhere. If the technician opens the refrigerant side of the system to check charge or pressures, federal law requires them to hold EPA Section 608 certification, and that rule applies the same way in every state. Washington's registration confirms the business is on record. It is the federal certification that says the person working on the refrigerant knows how to do it.

- What does AC maintenance include?
- A contractor checks the refrigerant charge, cleans the coils, tests the capacitor and other electrical parts, and confirms the system cycles on and off the way it should. They also check the condensate drain so it isn't backing up. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the check is never optional.
- How often does an air conditioner need maintenance?
- Once a year is standard, checked before the weather turns warm. Longview summers stay mild, with afternoons averaging around 74°F, so the system here isn't working as hard as one in a hotter climate. Even so, a yearly check catches wear on the capacitor or coil before it turns into a breakdown.
- Is AC maintenance worth it?
- Yes, because most cooling problems start small and show up during a check before they cause a full breakdown. A dirty coil or a weak capacitor gets caught early instead of failing on a hot afternoon. That matters even in a mild climate like Longview's, where the system runs less but still needs the same parts checked.
