FAQs about Fans & Blowers

What does an HVAC fan do?

• The fan on your HVAC system controls the blower; the blower is what circulates the cool or hot air in the space until the set temperature is reached.

Does running an HVAC fan reduce humidity?

• Sí. When you set the fan to auto, moisture from the cold cooling coils can be drained outside. If you have your fan running continuously, the unit does not have a chance to drain outside and blows moisture back inside. 

What’s the difference between evaporative coolers and air conditioners?

• Evaporative coolers typically only use water and electricity. They cool naturally and are best in open environments with fresh air (e.g., a warehouse space with large open doors). Air conditioners use a fan to distribute cool or hot air into a space until a set temperature is achieved. AC units work best in closed environments where exact temperatures can be achieved.
