Michigan cottonwood season produces one of the most consistent and most overlooked maintenance issues for residential air conditioning systems — and a recent AC repair in Farmington involving a completely plugged condenser coil is a timely reminder.
What cottonwood does to outdoor condenser coils:
• Airborne cottonwood seed fluff is drawn directly into condenser coil fins during normal operation — matting into the fin face in a dense uniform layer unlike loose debris
• A matted cottonwood coil restricts airflow across the entire heat exchange surface — one of the most severe restriction conditions a residential system experiences in normal operation
• Operating temperatures rise on every cycle — compressor stress increases and efficiency deteriorates in direct proportion to restriction severity
Why annual post-cottonwood cleaning matters:
• Michigan cottonwood season is predictable — its impact on outdoor coils is consistent every year
• Cleaning after cottonwood season concludes is one of the highest return maintenance investments available before peak summer heat arrives
After 80 years of Michigan summers the Matheson team has seen exactly what a neglected coil costs homeowners. Serving Oakland and Livingston County.
