The capacitor is the spark plug of your air conditioning system.
As mentioned in a previous post, the outdoor unit is the AC's motor. The capacitor is the part that stores that jolt and delivers it the instant the system needs to kick on. It's small, it's sealed away inside the unit, and you'll never see it. But it's the spark that starts the whole show.
Here's why it matters to you: when a capacitor starts to weaken, the motors it's supposed to start begin to struggle, straining to turn over, running hot, and eventually not starting at all. It's one of the single most common reasons an air conditioner quits on the hottest day of the year, and it gives almost no warning you'd notice from inside the house.
You don't need to know how to test a capacitor. You just need someone who checks it before summer asks it to perform. And that's exactly what the Air Conditioning experts at Aspen Mountain Plumbing are here to help you with.
