Prepare for Hot Weather With an Air Conditioning Tune-Up

Yes, an annual tune-up is worth doing, and the best time is before the first hot stretch of the year. An air conditioner runs hard for months, collects dust, and slowly loses efficiency as parts wear. A checkup catches those problems while they are small.

In the Tri-Cities, the season arrives quickly. One week the house feels fine and the next the afternoon highs are in the hundreds. That is the wrong moment to learn your system is struggling.

What happens if you skip it

Skipping maintenance rarely causes an instant failure. It works more slowly. Dirt builds up on the coils so the system cannot shed heat well, and it runs longer to reach the same temperature. Capacitors weaken until one gives out on the hottest day of the year. Small refrigerant leaks go unnoticed. Drain lines clog and lead to water damage.

Each of these shortens the life of the equipment and raises the odds of an emergency call.

What a proper checkup covers

A real tune-up is more than a quick look. It should be a list of tasks that a technician actually works through.

• Inspect and clean the outdoor coil and check the condenser fan motor
• Check refrigerant pressures and look for signs of a leak
• Test capacitors, contactors and electrical connections
• Clean or check the indoor coil, blower and condensate drain
• Verify thermostat operation and the temperature drop across the system
• Look at the ductwork, filter and airflow

Ask what the visit includes before you book. A tune-up that consists of a filter swap and a glance is not doing the job.

What you can do yourself

A few chores are safe for any homeowner. Replace the filter, which for a 1 inch filter usually means every one to three months during heavy use. Clear leaves, dust and cottonwood fluff from around the outdoor unit and keep plants a couple of feet away. Make sure your vents are open and that furniture is not blocking returns.

You can also rinse the outdoor coil gently with a garden hose with the power switched off. Do not use a pressure washer, since it will bend the fins. Anything involving refrigerant, electrical components or the inside of the unit belongs to a licensed technician.

There is a comfort side to this as well. A system with clean coils and a proper charge cools the house more evenly and runs quieter, and it is much less likely to leave you sweating through a weekend waiting for a part.

What a tune-up does for your bills and your budget

A system that is clean and correctly charged does not have to run as long to reach the temperature you set. That usually shows up as steadier bills through the summer, though the exact difference depends on the house, the equipment and how it has been treated.

There is a planning benefit as well. A technician who knows your system can tell you which parts are wearing, whether a repair is likely this year, and roughly how much life the equipment has left. That lets you budget for a replacement on your terms instead of during a heat wave.

Timing

Spring is ideal, since technicians have more room in their schedules and you have time to fix anything they find. If you are past that point and the heat has already arrived, book anyway. Catching a weak capacitor in June is better than replacing one in a heat wave, and the tech can tell you honestly how many summers the unit likely has left.

Air-Tech offers the AT Advantage Program, and every plan includes two visits a year, so the cooling season gets its checkup and the heating season gets its own. To schedule a tune-up, call (509) 392-2021 or stop by the office on N Oregon Ave in Pasco.
