Why it matters to you
Grass clippings, pollen, dirt and dryer lint can mat the fins, and a dirty condenser coil makes the system run at higher pressure and use more electricity through Greater Houston's long cooling season. Cleaning it is a standard step in an AC tune-up.
Practical guidance
Keep grass clippings, leaves and shrubs away from the cabinet, and never bend, scrape or pressure-wash the fins. Chemical coil cleaning and fin straightening belong to a licensed maintenance visit.
