Thanks to global warming, air conditioners are now an integral part of every household, especially in sub-tropical regions like Florida. No wonder, while buying an AC unit for the first time, homeoweners try to know about every detail of every component. The fan is a major component of the HVAC system, which, experts believe leaves, an impact on the air quality. The fact is, whenever you keep your AC running, the fan runs as well. But should it run when your room has reached the targeted temperature? This depends entirely on your choice. But before you take the decision, know the pros and cons of keeping the HVAC on 24/7.
What are the Pros of Keeping the HVAC Fan Continuously On?
- Every house has pockets which are either colder or hotter than the rest of the house. Such conditions arise when the air is not evenly distributed. Keeping the fan on helps circulate the air throughout the home. Frequently switching the fan on and off puts stress on the motor. The less you do so, more extended is the lifespan of your HVAC fan.
- Besides promoting air circulation, the AC fan is also designed to purify the indoor air. As the fan pulls air through a filtration and UV light system, leaving the fan on 24/7 helps in cleansing, making the conditions better for people having allergies.
Now that you have identified how keeping the fan on helps to increase the energy efficiency of HVAC unit, there are several disadvantages of leaving the fan continuously switched on as well.
What are the Cons of Keeping the HVAC Fan Continuously On?
- The average HVAC unit comes with a fan of 500 watts. When the energy usage of the fan is calculated, it is seen to consume as much energy as the refrigerator, costing you more than 50$ per month.
- Especially during the summer months, when the temperature outside is considerably high, air in the ducts closer to the exterior walls remains warm. If you keep your fan switched on, it pushes in the warm air from outside increasing the temperature within. To counterbalance this heat, the unit has to take the extra load.
- If the AC fan is allowed to run continuously, the furnace filter will clog up quickly. You will not only have to clean it in short intervals, but it might necessitate filter change more often than usual.
