Two short months, but hard ones

Your air conditioner in Spokane County only runs in July and August, with summer afternoons averaging 80°F. That is not a long season, but it is a demanding one, and a system that sat unused most of the year needs to be ready the day it turns hot.

The county has also logged 120 damaging wind events and 8 hail storms over the past ten years, with hail up to 2.75 inches. Wind can bend the fins on an outdoor coil or drive debris into the unit, and hail that size can dent a cabinet or damage a fan blade. A tune-up before summer catches that kind of damage while it is still small.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.

Washington requires contractors to register with the state.

That registration puts the business on file with the state. There is no trade exam behind it and no license, just a record that the business exists.

For a maintenance visit, what stands behind the work is federal, not state. Anyone who opens the refrigerant side of your air conditioner, to check the charge or get into the coil, has to hold EPA Section 608 certification, and that rule holds in every state whether or not the state licenses the trade.

What does AC maintenance include?
A technician checks refrigerant charge, cleans the condenser coil outside, and tests the capacitor and contactor that start the compressor. They check the filter and, if it is dirty, replace it. They also check the thermostat calibration and confirm the system cycles on and off the way it should. Anyone working on the refrigerant side has to hold EPA Section 608 certification, which is a federal requirement, not just a state one.
How often does an air conditioner need maintenance?
Once a year is standard, done before the season it gets used. Here that means having it looked at before July, since your cooling season is really just July and August. A yearly check catches a weak capacitor or a low refrigerant charge before a hot afternoon in the 80s finds it first.
Is AC maintenance worth it?
Yes, because most breakdowns start as small problems that a technician can catch while they still cost little to fix. A dirty coil makes the compressor work harder, and a weak capacitor can strand you without cooling on the one hot day you need it. With only two months of real cooling season here, you want the system working the first time you turn it on, not the day you find out it isn't.
