You’re relaxing at home on a sunny day in Hillsboro, but your air conditioner isn’t quite pulling its weight. Maybe it’s blowing out lukewarm air or taking forever to cool the room. If this sounds familiar, your AC coil Cleaning might be overdue for a little TLC. But how do you know for sure? Let’s break down the everyday clues that your air conditioner is begging for a coil clean, and why it’s especially important here in Hillsboro.
“A clean coil isn’t just about comfort—it’s about keeping your cool without draining your wallet.”
- Your AC Isn’t Cooling Like It Used To
One of the first things you’re likely to notice is your air conditioner just doesn’t get as cold as before. If you have to crank it up higher than usual or wait much longer for the room to cool off, that’s a pretty strong hint. Dirty coils act like a roadblock, stopping the system from doing its job. In Hillsboro, where spring pollen and late-summer dust float through open windows, coils can get clogged faster than you’d think.

- Your Energy Bills Are Climbing
Suddenly, your power bill jumps, even though your habits haven’t changed. What’s going on? When coils are covered in dirt or grime, your AC has to work double-time to keep up. That extra effort means more electricity and higher costs. It’s like riding your bike with the brakes half on—you’ll use a lot more energy to get where you’re going.

- Strange Noises or Odd Smells
If your AC has started making noises it never used to, like banging, buzzing, or rattling, dirty coils might be to blame. Debris can get stuck and cause vibrations or airflow problems. Sometimes, musty odors drift from the vents when the AC kicks on. That can be a sign of mold or mildew growing on the coils, especially in the Pacific Northwest’s damp climate. In such cases, professional coil cleaning is the safest and most effective way to restore clean airflow and prevent further damage.

- Ice and Water Where It Shouldn’t Be
Here’s a big one: If you notice ice forming on the outside of your AC unit or see puddles below it, that’s a sign the coils are struggling. Dirt blocks the coils from absorbing heat properly, causing temperatures to drop and moisture to freeze. Once it melts, you might spot water leaking where it shouldn’t be. This is more than just a nuisance—it can lead to bigger problems if left unchecked.
