How often should you clear 2 ft around outdoor AC unit?

These tasks are more about efficiency, longevity, and comfort. Not a huge deal if you miss one, but it pays off over time.

Staying on schedule matters beyond the repair bill: a consistent maintenance record is one of the factors in a home's Roots Home Health Score, and well-kept homes typically sell faster and closer to asking price.

How to do it

The outdoor condenser needs open airflow on all sides to release heat. Shrubs, weeds, and stacked clutter choke it and make the system labor to cool the house.

1. Cut back plants, weeds, and grass to leave at least two feet of clear space on every side.
2. Clear leaves, cottonwood fluff, and debris off the top grille and out of the fins.
3. Move anything stored against the unit and keep the top clear too.
4. Rinse the fins gently with a hose if they look matted.

Alternatives & optional extras

• Don't box the unit in with a tight decorative screen; it needs breathing room more than it needs hiding.
• Trim overhanging branches that drop leaves and seeds onto the unit through the season.

If you skip it

A crowded condenser can't release heat efficiently, so cooling drops, bills climb, and the compressor runs hot.
