You can temporarily lift this restriction by proving that you're human:How much does it cost to run a 12,000 BTU air conditioner per hour? The hourly operating cost for a 12,000 BTU air conditioner depends on factors such as the unit’s Energy Efficiency Ratio, "EER," or Seasonal Energy Efficiency Ratio, "SEER," room or house size and local energy rates. As of 2014, the average cost for energy is nearly 13 cents per kilowatt-hour, "kWh." How energy efficient is the Trane XR13 air conditioning system? How efficient is the Trane xe 1200 air conditioner? To calculate the hourly cost of a 12,000 BTU unit, divide BTUs by its EER or SEER to get watts per hour. Divide the watts per hour by 1,000 to find kWhs. Multiply the kWhs by the local electric company’s rate to calculate the cost per hour. For example, if the unit has an EER of 9, the average hourly cost of operation would be 17 cents. Use the area of a room to determine the proper air conditioner size estimate, which is measured in British thermal units per hour.

They love to set them on timers, to schedule them to come on in the afternoons, to circulate air to keep the house from getting stuffy. We felt the full force of that love last week when we released Advanced Fan Control, a feature that can do all of the above. Customers have already started using it. Many used to set Nest’s fan to Always On to bring cool air upstairs in summer or just keep air fresh, then they’d go to bed or leave the house and forget to turn it off. Now homeowners can schedule the fan to run from 6-11 p.m. or 8-10 a.m. and forget about it. It’s almost like having an air conditioner. Advanced Fan Control is proving to be one of our most popular new features—the love for fans is ubiquitous.

But so is the misinformation. With all this talk about fans, we’re hearing from more and more customers who’ve been told it’s energy efficient to keep the fan on all the time, 24 hours a day. Whenever the topic is brought up, it’s a debate. Leaving the fan on seems to make sense, after all, especially in summer. If the fan can keep things from getting stuffy, you’ll use your energy-hog of an air conditioner less, and less AC will always save energy. Turns out, it could cost you hundreds of dollars a year. While using the fan instead of the air conditioner really is energy efficient, leaving it on all the time usually isn’t. The average air conditioner has a 500 watt fan, which can use about as much energy over the course of a year as a refrigerator. The costs of running it 24/7 quickly add up. Newer systems have fans that use less energy, but keeping them on all day can cause other problems. In the summer, the ducts that run through your attic or close to your walls can heat up, filling with warm air.

Without the AC to cool it down, the fan just blows hot air into your house. You end up running the AC more, not less, to counteract all that extra heat. Hot ducts can be a problem even if you don’t have the fan running all the time—you may be cool and comfortable in your bedroom, then when you turn on the fan on for the night, you fill the room with hot, stale air. The fan can giveth and taketh away. That’s why Advanced Fan Control gives you a few different ways to control the fan, so you can find what works for your home. For those who want to circulate the air, we added an option that lets you run the fan for 15, 30 or 45 minutes every hour. You get the comfort benefits of a fan blowing all the time, but significantly reduce the fan’s actual runtime. For Nesters who want the fan on for a particular period of time - while they’re asleep, for example, or just in the afternoon when everyone comes home—we’ve created a simple scheduler and a timer. You can turn on the fan exactly when it’s most efficient—when it replaces air conditioning—and it’ll automatically turn off when you tell it to.

The fan deserves all the love it gets—it can make a huge difference in your comfort and your energy bill. But as with all things wonderful and beloved—chocolate, Christmas, chocolate—you can get too much of a good thing. This post is part of our HVAC 101 series about how to make the most of your heating and cooling system. Previously we covered finding holes in your ducts and insulation.Programmable thermostats can save you hundreds in heating and cooling costs. When the thermometer rises in the summer, the cost of turning on an air conditioner may seem minor compared to getting some relief from the heat — but knowing how much air conditioning costs and how you can reduce that cost makes good fiscal sense. According to the Energy Information Administration, Americans spend more money cooling their homes than any other single usage of electricity, accounting for 22.4 percent of the average household electric bill in 2010. Typical Electricity Costs The town of Wellesley, Mass., has estimated the average cost of running central air conditioning in a typical home for six hours a day will use 900 kilowatt/hours (kWh) per month.

At a cost of $0.134 per kWh, this amounts to $120.60 per month. A large 12,000 BTU air conditioner, like that in a window, running six hours each day will consume 270 kWh, at a cost of $36.26 per month. A smaller 6,500 BTU room air conditioner will consume 144 kWh at a cost of $19.34 per month. Understanding Kilowatt-Hours The kilowatt-hour (kWh) is the standard unit of measurement for electricity in the United States. This is 1,000 watts of electricity being used for one hour. To calculate how much your air conditioner costs to run for an hour, look for its wattage on the box or in the instruction manual and multiply this by the number of hours you use it each day. For example, a 1,000-watt air conditioner running for one hour consumes 1 kWh. By comparison, a 60-watt light bulb running for an hour uses 0.06 kWh (60 watts divided by 1,000). The cost of electricity varies by region. While the average cost in the US in 2011 was 12 cents per kWh, it was as high as 33 cents in Hawaii and as low as 8 cents in Idaho.

Check your electric bill to determine your cost. Air Conditioner Size and BTUs The size of air conditioner you should purchase depends on the size of the rooms it will be cooling, how well your house is insulated, and whether or not the rooms are facing direct sunlight. An air conditioner's ability to cool is measured in British Thermal Units (BTUs). For example, to cool a 100- to 150-square-foot room that is well insulated and not facing direct sunlight, you need about 6,600 BTUs, which requires about 1,934 watts. The same room in direct sunlight requires about 7,260 BTUs, using 2,128 watts. A poorly insulated room in direct sunlight needs about 9240 BTUs, using 2708 watts. Cutting Costs A programmable thermostat can reduce the cost of central air conditioning if you program it at a higher temperature while you are at work and while you are sleeping. The temperature you set the air conditioning at should be relative to the outside temperature. If the temperature outside is 90 degrees, setting the air conditioning to 78 should feel quite comfortable in comparison.
