For many of us, air conditioning results in our biggest utility expense during the summer months. Well, summer is officially here, and so is Prof. Dealzmodo to lay some tips on you for keeping cool without going broke. Fans At the very least a regular fan, a twin window fan that takes advantage of cool night air, room to room fan, or even a bed fan could help save a little extra money—especially if the outside temperature cools sufficiently in your area. If you have the option of installing a ceiling fan, it can be one of the simplest and most inexpensive ways to reduce energy costs in the home. The average price is around $100 per fan, they can be easily self-installed (as long as you have an existing ceiling light) and they can save you as much as 40% on your energy bills this summer. Take this example from Progress Energy: ...a 48", 75-watt fan used 10 hours a day at half speed or less would cost $.50 to $.90 a month to operate. For a 1,500-square-foot house with air conditioning using two ceiling fans and raising the thermostat setting could save about $70 to $200 over a six-month cooling season. This is precisely why I just ordered four new fans for my home. Three of the four will be installed upstairs in each of the bedrooms. There will be absolutely no need for A/C at night, and I expect to dramatically lower central air usage on the upper level during the day. Window A/C Units: Who Should Have One? The bottom line is that window units use far less electricity than central air units. For example, a typical, medium-sized window unit might use 500 to 1440 watts of electricity per hour while a 2.5 ton central system might use 3500 watts over the same span. Because central air units cool an entire home, users often waste energy in areas that are not occupied. For example, if you live in a small apartment, a 12,000 BTU window unit could effectively cool a 640 square foot space for an upfront cost of around $300. This Fridgidaire model is also Energy Star certified, meaning that it should provide at least an additional 10% savings in monthly energy costs—making it a wise investment when compared to a traditional model. In an apartment around 800 square feet, that would most likely cover the main living space and could be supplemented with something as small as a 5,000 BTU unit for a bedroom. Hell, you might even be able to get away with only a fan—after all, bedrooms see most of their use after the sun has gone down. Things to consider when buying a window A/C unit: • Bigger is not better. Too many on/off cycles will reduce efficiency and add result in unnecessary wear and tear. Make sure your A/C unit is sized properly for your room by matching capacity with square footage. • Make sure your unit has at least three speeds (low, medium and high). • Buy a model with a thermostat to fine tune your comfort level and save electicity. • Clean your filters regularly. • Choose a model with a timer. This gives you even greater flexibility and ensures that the unit is only running when needed. • Consider building a unit directly into your wall to eliminate the hassle of moving it every year. You can also put an insulated / weather-stripped cover on through-the-wall units in the fall. [HVACKey] So, to answer the question "who should have one?," I would suggest that people living in small apartments or homes seriously consider investing in a window A/C unit or two. Even if you have central air, keeping it off in favor of
