However, running a 20W-50W ceiling fan vs. Running a ceiling fan also adds to the electricity bill. The 30% reduction in cooling expenses saves an average household about $80/year. This increases the electricity bill less significantly.Īccording to the EIA’s 2015 study, we spend about 12% of all our energy expenditure on cooling alone. Increase in electricity costs because we have to power the ceiling fan.This reduced the electricity bill significantly. Reduction of air conditioning costs up to 30%.To adequately calculate how much less you will pay for electricity as a result of that, we need to take into account two factors: Of course, it always makes sense to set the ceiling fan rotation for summer when using an air conditioner. How much exactly? Let’s calculate a bit: How Much Does Correct Ceiling Fan Direction With Air Conditioning Save?
Just by choosing the correct ceiling fan direction for cooling, you can save up to 30% on your AC costs. Nonetheless, the temperature we perceived due to the summer counter-clockwork fan setting is lower.Ĭorrect ceiling fan direction with air conditioning will help us reduce the air conditioning costs. The room has the same temperature with or without the fan. Now, it’s important to understand that the overall temperature of the room ceiling fan is in does not decrease, even if you have the correct summer ceiling fan rotation. You will feel that the temperature in the room doesn’t change due to the evaporation cooling effect from your skin. That’s why DOE, according to their experimentation, determined that you can set the air conditioner setting 4☏ higher in the summer.Įxample: If you set the thermostat to 68☏ in the summer, with the correct summer ceiling fan direction, you can now set it to 72☏.
#Fan clockwise in summer skin
The column on air increases the evaporation from our skin and stimulates the body’s natural cooling mechanism. This downward airflow direction creates a light cooling breeze. When set to the counterclockwise direction in the summer, the ceiling fan pushes the air downward. Let’s first look at what direction should a ceiling fan go in summer, and expected electricity savings: Ceiling Fan Direction For Summer (Counterclockwise + AC Savings Calculation)Ĭounterclockwise direction is the ‘ceiling fan direction summer’. The upward cold air direction, generated by the ceiling fan clockwise direction, will displace the warm air at the top of the room, and push this heated air down.

In the winter, the ceiling fan direction should be clockwise.We won’t have to push the air conditioner so hard. The downward breeze, generated by counterclockwise fan spin direction, will make us feel cooler. In the summer, the ceiling fan direction should be counterclockwise.With all this said, here is the correct fan direction by season: Even worse, you will likely increase the cooling and heating costs significantly only because the ceiling fan reverse switch was not turned on/off. Of course, if you don’t correctly use the ceiling fan direction switch when the seasons change, you will not benefit from these savings. In the winter, you can save up to 15% on heating costs if you know which fan spin direction to choose. “If you use air conditioning to cool your home, a ceiling fan will allow you to raise the thermostat setting about 4☏ with no reduction in comfort.” ( DOE on ceiling fan use in summer)īy adequately setting ceiling fan rotation direction in the summer, you can save up to 30% on your cooling costs (we’ll explain why, and calculate US dollar AC savings further on). “Does ceiling fan direction really matter?” Let’s first answer the most obvious question: The key here is to understand just how much of a difference adequate ceiling fan direction makes. counterclockwise ceiling fan direction and make some savings calculations for cooling and heating (estimations). We are going to explain which way should a ceiling fan rotate: Even more importantly, by picking the wrong ceiling fan rotation for a season, you will unnecessarily raise your cooling and heating bills by over $100/year. Some homeowners might be surprised just how different the correct ceiling fan direction in summer/winter makes. On a ceiling fan, which way is summer? Which fan direction should you choose for winter?
