What is the fastest way to defrost an AC coil?

What is the fastest way to defrost an AC coil is to turn off cooling mode and run fan only to circulate warm indoor air over frozen evaporator coil, which safely melts ice relatively quickly without damaging coil. Steps for fastest safe defrost: first, turn thermostat from COOL to OFF, then set fan to ON not AUTO, this runs indoor blower without compressor, warm air from house helps melt ice within 1 to 3 hours depending on ice thickness. Second, turn off system at breaker for safety if you need to access coil, open access panel to allow warm air circulation. Third, you can use hair dryer on low heat held at distance to gently melt ice, never use high heat or sharp objects to chip ice as you may puncture copper tubes causing refrigerant leak. Fourth, place towels and bucket to catch water as ice melts to prevent water damage. Fifth, replace dirty air filter that likely contributed to freezing and open closed vents to restore airflow. Do not run AC in cooling until ice fully melted. If coil freezes repeatedly, call technician to check refrigerant charge and blower motor. Fastest method is fan only with filter removed to maximize airflow, typically 60 to 90 minutes.
