Can I save money by getting a window air conditioner and using my central air less? August 8, 2012   Subscribe Will turning up the thermostat on my central air and buying a window AC unit for the one room I use the most make a significant difference in my electric bill? This is hopefully a simple question, but I'm not confident that my assumptions are correct. I recently bought a house, it's a 2-story that's about 1750 square feet, located in Michigan USA. The house has a central air unit that looks very very old, but still functions well. The thermostat in the house is on the ground floor, and I've kept it set to about 70 degrees Fahrenheit when I'm home, since the upper floor tends to be at least 7-8 degrees warmer than the ground floor, and I spend more of my time upstairs. I am currently the only person living here. The outside temperatures during July were generally in the 90s, occasionally in the 100s. I knew that cooling a 1750 square foot house was going to cost more than cooling my old 1-bedroom apartment.

But I was surprised by just how much more. My electric bill last month was $260, twice the highest amount I ever paid while living in an apartment! I'm guessing that the AC is the main difference between the bills at these two places, since everything else I own is more or less the same, and is getting the same amount of use (same computers and TVs, comparable refrigerator, etc). I'm trying to figure out how to save money on my electric bill while at the same time cooling my upstairs bedroom/office more effectively. I'm thinking I could put a window air conditioner in my bedroom upstairs, and then turn the downstairs thermostat up to 78 or so. My question is though: Would this actually save me any money? I'd still be using the central air to cool the rest of the house, just not as much. Would the difference be enough to justify the cost of the window unit? In particular, I was looking at purchasing the Frigidaire FRA086AT7, which costs $200. To justify that expense in the short-term, I'd hope to save at least $40/month on my electric bill by using this strategy.

I really don't have a good feel for that the impact on my energy usage would be. high side of ac unitEspecially since I don't intend to turn the central air off altogether.top five ac units If this wouldn't be an effective money-saver, do you have any other suggestions?air conditioning fan will not turn on If you have any hard data, or you've done something like this and can tell me about your experience, I'd love to hear it! You can blame (or thank) MINI Cooper for this. Ever since the cheeky little Brit was reintroduced in 2003, buyers have been going gaga for small, personal city cars. Where small cars used to be cheap, inexpensive transportation, this new breed combines style, personality and performance along with the premium price tag.

The key players in the game are currently MINI, Smart, the new FIAT 500, and now, the all-newThe funniest thing about this is that the largest car in the class is...you guessed it, the MINI. If you're an urban dweller who has to fight it out for parking, or an eco-minded driver who doesn't want to give up the toys. If you find the Smart too small, the MINI too pricey, and the FIAT questionable on reliability, the iQ hatchback could be just right. First of all, you either like the Scion iQ styling or you don't. If you're looking for cheap transportation or need 4-passenger capacity, the sedan (both all-new for 2012), Honda Fit and Mazda2 will better fit the bill. The 2012 Scion iQ is a master of hatchback packaging, fitting 2 +1 seating (we can explain) into a stylish package that is incredibly small on the outside, yet surprisingly roomy inside. And the front-drive, 3-door hatchback looks like the kind of futuristic cars we all thought we'd be driving by now.

When you're behind the wheel of the 2012 Scion iQ hatchback, it's easy to forget you're in a car that's shorter than a MINI. You sit tall, like in the...... FIAT 500, and that gives excellent visibility. Unlike the FIAT, the Scion feels more sleek and coupe-like, thanks to a smaller greenhouse. Scion puts the dashboard and center stack further away, enhancing the impression you're driving a larger car. The drive doesn't betray it – the 92-hp 4-cylinder is smooth and the iQ provides a surprisingly quiet ride. Freeway speeds are comfy, with only a little nudge from side winds betraying the short wheelbase. In town, it's only when you crank over the steering wheel, when the 2012 iQ turns on it's heels like an exuberant Jack Russell Terrier, that it strikes you how maneuverable the little Scion is. Keep the CVT automatic transmission in Sport mode, and you'll get more zippy performance, but it can't match the Italians (FIAT) or Germans (MINI) for road feel and driving fun. You wouldn't think you'd get excited about a steering wheel, but the standard Scion iQ wheel has a fat, leather-wrapped rim, and angular contours that make it look like it came from a Ferrari.

By pushing the dashboard and console way forward, the Scion iQ puts the front passenger slightly ahead of the driver, adding enough room for a passenger in the back. No such luck for those behind the driver, though. Think of the Scion iQ as a 2-seater with room for an occasional third, and you've got it right. Considering the hatchback's tiny overall length, room up front is impressive. The seats are ample-sized and quite comfortable too. If you've got both rear seats up, cargo room is non-existent.) Even more impressive is the iQ interior design, with beautiful curved door handles, a curved cascading center stack, and nice quality materials throughout. It's a nice place to spend time. When you think about the Scion iQ's competitors, you realize that both the MINI Cooper and the FIAT 500 are retro-classic designs that have been re-envisioned. The Scion charts a bold new course. It's funky and aero. So we were surprised our 2012 Scion iQ test car didn't turn more heads. We think it's the dark charcoal (magnet gray metallic) paint.

We've seen other iQ hatchbacks in a bright orange ("Hot Lava" to Scion) and white ("Blizzard Pearl"), and they really grab your attention. Because it's a Scion, you have a wide choice of personalization, including accessory body parts and wheels, so making one your own should be easy. The 2012 Scion iQ comes impressively equipped. At its $15,999 starting price, standard goodies include air conditioning, power locks/windows/mirrors, keyless entry with electronic rear-hatch locking system, a thumping 160-watt Pioneer audio system with HD technology, a USB input for your iPod, Bluetooth connectivity, 16-inch covered steel wheels, and a continuously variable automatic transmission (CVT). Buyers with safety concerns about the iQ's small size will be happy to know about its armada of airbags, including driver and passenger front, knee, seat-mounted side and side curtain air bags. There are also unique front seat-cushion airbags and a rear-window airbag that deploys around the rear headrests.

There's basically only one Scion iQ model, but like other Scion models, there's a nice array of accessories. On the outside, there's a 4-piece aero kit, rear spoiler, mudguards and fog lights. For the inside, the usual assortment of floor mats and cargo nets is available, plus a cool interior-lighting kit. Those of you looking to terrorize your local on ramp can plump for (Toyota Racing Development (TRD) lowering springs and a rear sway bar. Alloy wheels are available, as is a full-featured navigation system. The front-wheel-drive (FWD) 2012 Scion iQ gets its kicks from a 1.4-liter 4-cylinder engine that puts out 94 hp. It may be small, but it's a technical powerhouse, with dual overhead camshafts, four valves per cylinder and dual variable valve timing. Toyota recommends 87-octane gasoline – which when combined with EPA fuel-economy estimates of 36 mpg city and 37 mpg highway, you won't be spending much at the pump. 94 horsepower @ 6,000 rpm 89 lb-ft of torque @ 4,400 rpm
