How to keep AC fan on?

However, there are a few cases where it may be more advisable to keep your fan setting on automatic: 1 If Your HVAC System is Located in the Attic – Today’s homebuilders avoid placing HVAC systems in the attic, and for good reason.

This increases cooling costs and decreases efficiency. 2 Your Home Has Old HVAC Equipment – Advances in technology have made air conditioning systems exponentially more cost-effective and energy efficient. If you have an older furnace fan installed, leaving it on all day may raise your energy bill rather than lower it. 3 Leaky Ductwork – Homes built after 2015 are now all required to have their ductwork tested for air tightness. In older homes, this can pose an issue. Most homes lose about 20% of their cooling due to poorly connected ducts, meaning a fan that is blowing all the time will not be as effective.
