AC Maintenance Before Summer: Filter Inside, Wiring Outside

AC maintenance before summer starts indoors, because the furnace blower is what moves your cooled air. A clean filter, a clear drain and tested electrical parts outside are what keep an AC from quitting in the first hot week.

What you’re seeing in this video

In a laundry room, a tech with glasses and a SwiftPro cap slides the thick media filter out of a filter cabinet mounted on the side of a gas furnace. That deep pleated filter holds far more dust before it clogs than a thin one-inch filter does.

Outside a row of townhomes, a younger tech in a grey hoodie and red gloves tests the wiring at a condenser with a yellow clamp meter, with a wrapped SwiftPro van parked nearby.

Why it matters in your house

  • Media filters in those four- or five-inch cabinets often last six months to a year, which also makes them easy to forget. Write the change date on the frame so you know.
  • Spring is when a tech can catch a weak capacitor, a clogged drain line or a dirty coil, before the first heat wave books up every AC company in the area.
  • Tune-up benefits are real but modest: steadier cooling, fewer breakdowns and wear caught early. The biggest one is avoiding a dead AC on the hottest day of the year.

When should I get my AC serviced before summer?

April or May is ideal in Northern Virginia, once it's warm enough to run the AC and before the first real heat. That leaves time to order a part if something tests weak. A tech also gets more reliable readings on a warm day, when the system can run under a real load.
