Air conditioning makes the hottest summer days more enjoyable, but rising energy costs and the growing awareness of energy conservation and resource depletion demands you cool your home as cheaply and energy efficiently as possible. Deciding which cooling method will save you the most -- three window air conditioners or a central air unit -- depends on a few factors. Cooling your home with the proper system saves you money and electricity, and keeps you completely comfortable no matter the temperature outside. Comparing Energy Usage Considering that the average home uses more electricity for cooling than for any other appliance or accessory, if you want to save money on your utility bill, carefully consider your cooling choices.

A central air unit uses more energy to cool your home. As Mr. Electricity states, a window unit uses anywhere from 500 to 1440 watts to run, while a 2.5 ton central unit (about the size for a typical 1,500- to 2,000-square-foot home) uses about 3,500 watts. It's not simply about the size of area cooled, but the fact that central air involves the furnace, too. how much is an ac unit motorThe air does not flow to the rest of the house without the furnace blower -- so more running parts equal a larger power draw. window air conditioner repair diyCost of Unit Installation It's simple to see that a central unit uses more power than a window unit, but there's more to your cost than just the energy draw. how long to install an ac unitOnce you factor in the purchase price and cost of installation, your cost per use may rise significantly.

Dividing the total price and installation labor cost by the months you use it dramatically illustrates the true cost of just having the air conditioner, without figuring in the utility bill. Window units sell for a lot less than central units, and the installation typically is do-it-yourself. It's Not All About the Unit Another factor when determining which cooling unit is best for your circumstances is the condition of your existing HVAC system. No matter how efficient your central air unit, if the ducts the cool air travels through are full of holes, or poorly insulated and exposed to temperature extremes, the efficiency of the whole system goes down -- and the cost goes up. If you choose to run a central air unit, insulating your ducts, and inspecting and maintaining the whole system is important, although it adds to the cost. Compared with window units, which blow directly into the room and need little but occasional cleaning unless they go out, a central unit again costs more. Verdict Although it costs more to purchase and install a central unit -- and responsible owners also spend more on annual service calls for maintenance and inspection -- if you plan to cool three or more rooms, the most cost-effective and energy-efficient choice is the central unit.
