If your thermostat has a “fan circulate” option, there are a few reasons why you might choose
not to use it:

1. Increased Energy Consumption: Continuously running the fan can lead to higher energy
   usage and increased utility bills.
2. Wear and Tear: Constant operation of the fan can lead to faster wear and tear, potentially
   reducing the lifespan of your HVAC system.
3. Temperature Inconsistency: Running the fan constantly can sometimes lead to uneven
   temperature distribution, especially if your HVAC system is not well-balanced.
   4. Does NOT Dehumidify: Running the fan does not dehumidify the air and instead pumps
   moisture through your ductwork, stimulating mold and bacteria growth.

Therefore, Advanced Air Duct Cleaning recommends that you should not run your fan on circulate mode. For any other questions about your air conditioning, give us a call. Our team of experts provide air duct cleaning services to homes and businesses in New Jersey. Reach out today to get started.
