Defeating the "Cottonwood Clog"

Location Focus: Salt Lake City (The Avenues, Sugar House, and Millcreek)

Estimated Time: 20 Minutes

Difficulty: Easy

The Problem: Salt Lake’s "May Snow"

Right now, the cottonwoods along the Jordan River and throughout the valley are releasing their seeds. While it looks like a summer wonderland, those fluffy white fibers act like a sweater for your air conditioner.

When your outdoor AC unit breathes in, it sucks that fluff onto the cooling fins. This forces your system to work twice as hard to pull in air, leading to higher Rocky Mountain Power bills and potentially a blown compressor right before the July heatwaves hit.

The Hack: The 20-Minute Deep Breath

You don't need a professional HVAC tech to handle this. You just need a garden hose and a little bit of patience.

1. Power Down: Safety first! Turn off your AC at the thermostat or the outdoor disconnect box.

2. Clear the Perimeter: Use a broom to sweep away any loose "snow" or dead leaves around the base of the un

   it.

3. The "Inside-Out" Spray: This is the secret. Don't spray the fluff into the unit. If you can see through the top grate, try to angle your hose to spray from the inside of the unit outward. This pushes the cottonwood clogs out of the fins rather than packing them in deeper.

4. Gentle Pressure Only: Never use a power washer! The aluminum fins on your AC are delicate and will bend easily, which permanently restricts airflow. A standard garden hose nozzle on a "shower" or "stream" setting is plenty.

💡 Pro-Tip for SLC Residents

If your neighborhood is particularly dense with cottonwoods (we’re looking at you, Liberty Park area!), consider checking your unit every Wednesday until the "snow" stops falling. A quick 5-minute rinse once a week is much cheaper than a $5,000 system replacement!
