Fan Watt Draw (FWD)
Take Out The Guess Work With a Fan Watt Draw Test
Fan Watt Draw required for new installations or any modification that requires over 75% of the accessible duct system to be replaced. This relatively simple and straightforward test determines how many watts your fan uses to power the system. We then take the total watts used and divide it by the total measured airflow to determine precisely how much energy it takes to run the fan. This can help identify problems associated with poor efficiencies such as dirty air filter, clogged coil, or restricted airflow in the system.

Additional Information About Fan Watt Draw Tests
Any homeowner who has recently done a mechanical changeout in their home needs a cooling coil airflow test.
This test is required anytime a mechanical changeout has been performed. This requirement applies to all climate zones in California.
The main purpose of an FWD test is to determine if system is drawing too much or not enough wattage.
For an FWD test we use a plugin watt meter.
