Whoever wrote this answer has the math correct, I will admit it. 220 volt circuit is two 110 volt circuits put together. 110+110=220. As seen below in the following equation, the 220 unit and 110 unit use the same amount of wattage, if you double the 110 volts amperage use. 220 volt circuits are used with major appliances such as air conditioners, dryers and electric oven/ranges for this reason. The amount of current they draw (amperage). The reason behind using a 220 volt circuit verses the 110 is the wire size needed to carry the amount of current used. It comes down to the cost of wiring and that is it. In the equation below the 220 volt/10 amp unit would only use 14 gauge wire. The 110 unit would have to use a larger gauge wire to perform the same function with 12 gauge wire. The larger the gauge number, the smaller the wire, thus less the cost. Sorry to say there is no cost difference to operate a 110 A/C to a 220 unit. Unlike the statement made below, it will take you forever to see the cost difference in your electric bill as you will be using the same amount of power for both. If the fellow below does not believe me, try this on for size. Take amp meter to L1 and view the use. Then take a second amp meter and view the use of L2. Now that you have simotaneous readings, add them together. See, no savings at all. A 220 Volt appliance uses half of the current that a 110 Volt appliance does. Your house power starts with 220V with neutral phase grounded. 110V is obtained from either one of the 220v wires and neutral. Your meter measures current at the 220V rate. If you use a 220V appliance your meter will record power used. If you use the half voltage of 110V you will have to double the current to obtain the same power output. Your meter will record double what you are actually using. Your circuit panel is laid out for two 110V circuits and their combined 220V. Orginal layout of your house wiring was a gusse at trying to pair 110V devices that may be on simultaniously. This helps ballance the two 110V circuits and gives a truer reading on the meter. In addition to this meter error are current losses. The more current the more loss! example: 220V X 10A = 2200W or 110V X 20A = 2200w So the 220V appliance is a winner in both cases. DEFINETLY ENERGY EFFICIENT ! The catch is you need a 220V outlet installed. Depending on your cost for the outlet it may take an few extra months to realize a savings.

∙ 14y agoThe EER (Energy Efficiency Ratio) of an air conditioner is BTUH (British Thermal Units per Hour) divided by watts. (A good EER is greater than 13.0) Actually, the best measure is the SEER (Seasonal Energy Efficiency Ratio) which is the EER measured over the entire cooling season. Given equal BTUH and EER, both air conditioners would use the same kw. If one operated at 110, it would use twice as many amps as the one at 220, with the same effective power, so the end result would be the same. However, you have to consider if the two air conditioners are fighting each other, i.e. one is off while the other is on due to inequal thermostats, and you have to consider the power factor, as kw is not the same as kvar (kilo volt-amps). You also need to consider that each air conditioner needs a dedicated circuit, so you are committed to two circuits with two air conditioners, and you might as well put in a single 220 for one air conditioner It is probably best, and cheaper, to run one big air conditioner on 220, unless you intend to cool two separate spaces, as the purchase price per BTUH is not linear. The added cost of running 220 is not that large in comparision to the price, but you need to shop around and look at the big picture. (But don't forget the "fighting" issue - that would definitely impact things.)

Are ductless air conditioners better than ones with ducts?
Ductless air conditioners are not better than ones with ducts. The reason why ductless air conditioners are not better than ones with ducts is that they don't remove the hot air as well.
How was air conditioning invented?

What is SEER in terms of home air conditioning?
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER). The higher the rating the more efficent the air conditioner is. A common misconception is that the SEER rating is also used on heating systems but it's only for air conditioners.
Why the air conditioner is bad for the environment?
It uses up energy to cool and creates more heat to do that, which it releases into the environment. Many air conditioners also contain hydrofluorocarbons which destroy the ozone when released into the air. Air conditioners are also negative for your body's natural adaptation to hot and cold environments. The more time you spend in air conditioning, the less able your body is to coping with actual heat when you move outside an air conditioned environment.
Why does white smoke come from window air conditioners in your home?
Actually it is not smoke but water molecules when it is working properly. AIR CON will remove most of the water from a room
What are the different types of home air conditioners that are available?
Different types of home air conditioners are: Central Air Conditioners Split System Air Conditioners Packaged Central air conditioners Portable air conditioners Ductless air conditioners and, Evaporation Coolers
Where was air conditioners invented?
When was Air Conditioners invented
Are portable air conditioners expensive to run?
Portable air conditioners are not expensive to buy, but they are more expensive to run than a whole house air conditioner. However, if your house does not have central air, a portable air conditioner is a good alternative.
What is meant by 220 volts AC?
In US household electrical service there are two "hot" 110 volt wires and one ground. Only one hot wire is connected to a normal outlet or light fixture. To wire a 220 volt alternating current outlet, both hot wires are connected to the outlet. This is used for appliances that need more power than is provided by 110 volts like electric ranges, clothes dryers, air conditioners.
Why would plugging in an AC unit in a wall receptacle cause the fuse to blow or breaker to trip?
Is the receptacle a 110 or a 220 outlet? If it's a 110, it needs to be a 220. Are there other appliances, lights, etc. wired on the same outlet? If so, you may have to re-wire so that no other appliances, lights, etc. are wired into the same breaker. Usually the larger appliances such as air conditioners, central heat systems are wired to a separate breaker or fuse.
How much voltage required for air conditioner?
The wire sizing of any equipment is related to the amperage that the equipment draws. Look on the air conditioner and restate the question and give the amps that the unit uses and at what voltage.
What are the advantages of cabinet air conditioners?
Cabinet air conditioners produce clean air and don't allow outside air to enter inside them. All the air that flows through these air conditioners is filtered and compressed.
Are there any portable air conditioners that are energy star rated?
no there are no portable air conditioners.
Where can I find air conditioners?
Find the right air conditioners and heaters at the right prices from Walmart.com.They offer the best air conditioners ever sale on the united states of america.
Where can one purchase Rheen air conditioners?
You can purchase Rheem Air Conditioners online from stores such as The Home Depot. You can also purchase Rheem Air Conditioners used from eBay or Craigslist.
Why are air conditioners used?
Air conditioners are needed in hot climates to reduce the temperature and humidity of the air. Humans like to be comfortable.
Where can one find caravan air conditioners?
Caravan air conditioners can be purchased from home appliances stores such as Home Depot. There are also sellers who put up caravan air conditioners online for sale.
