Here are some additional details regarding the cost differences between whole house fans and air conditioners:
Electricity Usage:
• QuietCool Whole house fans use a very energy effiencent motor to move the outside air into your house. This requires a fraction of the electricity needed to actually cool the air like an air conditioner does.
• Air conditioners have to compress refrigerant, move it through coils, and run fans to circulate the cooled air. This thermodynamic cooling process requires significantly more electricity.
• A typical whole house fan uses between 500 and 1,500 watts of power, depending on the size. An air conditioner can use between 2,500 and 5,000 watts, or even more for larger units.
Energy Consumption:
• Based on the lower wattage and shorter runtime, whole house fans typically consume 500-1,000 kilowatt-hours (kWh) per year for cooling.
• Air conditioners typically consume1,500-3,000 kWh per year, or even more for larger homes and higher thermostat settings. This is 2 to 4 times more energy than a whole house fan.
So in summary, the cost differences come down to the mechanical simplicity and passive cooling method of whole house fans, compared to the active thermodynamic cooling process required by air conditioners. This results in significantly lower electricity usage and runtime, translating to lower energy bills.
This is why WHF's have the fastest ROI for any green energy product on the market!
