Is your RV air conditioner struggling in the heat? In this complete 6-month maintenance routine, I show you exactly how to keep your Dometic (or Coleman / GE) roof-mounted AC running efficiently and quietly — and avoid a $1,200 replacement.
Whether you’re full-time or weekend warrior, these simple DIY steps will dramatically improve cooling performance and indoor air quality.
What we cover:
• Upgrading to premium MERV 11 + charcoal filters from Riveted Market
• Installing and demoing the Airlock One hospital-grade air purifier (pet dander, pollen, food & body odors — gone!)
• Full rooftop deep clean: evaporator & condenser coil cleaning with the right (safe) products
• Electrical check: testing the capacitor with a multimeter + when to replace this $20 part
• Troubleshooting tips: fixing the “deck of cards” sound, loose fan bolts, and the compressor “scratch test”
• Quick “wavetop” overview of how your RV AC actually works (airflow, refrigerant cycle & heat pump mode)

• Airlock One → airlockusa.com (Use code THIRTEENADVENTURES)
