Depends on where you live. If you live far enough north, you won't use the a/ c enough for a more efficient central air system to pay off the investment. In general window and casement units are the lowest efficiency, then the split systems, and the central a/c systems are the most efficient. All but the central air let you cool only the rooms you are using, so there is a potential savings if you are only using a few rooms in a large house.

Can a central air conditioner be installed in a house that currently uses room air conditioners?
Yes, a central air conditioner can be installed in a house that currently uses room air conditioners as long as there is a place to put the fan outdoors.
Different Kinds of Home Air Conditioning?
Whether you live in a climate that has unbearably hot summers, or you summers are more mild, chances are at one time or another you’ve thought about buying an air conditioning unit. There are several different types of air conditioners that serve several different needs. Central Air Conditioning A central air conditioning unit is a large box with a fan and motor that sits outside of your home or business. It is connected through a series of ducts to every room of your house. When you turn it on, the fan blows the hot air away from the unit and the unit sends cold air into the house. It is called central air conditioning because the power source is centralized in that single outdoor unit. Most homes that are built in warmer climates have central air conditioning built in from the beginning. Schools and businesses tend to use central air conditioning as well. Portable Air Conditioners If you live in a milder climate you probably don’t have central air conditioning built into your home. Unfortunately, even the mildest climate experiences uncomfortable heat every now and then. Portable air conditioning is perfect for areas that don’t experience heat very often. A portable air conditioner is usually about three feet tall. They have a blower that sends cold air into the room, and a water tank that collects the moisture from the air. The hot air is expelled through a vent that runs to the window of the room. Portable air conditioners store easily when they are not in use, and they can cool a single room very nicely when needed. Window Air Conditioners A window air conditioning unit is similar to a portable air conditioner but it is far more powerful. Window units are box shaped and are installed into the bottom half of the window. The installation is relatively permanent because the air conditioners are very heavy and difficult to move. Once the unit is placed safely in the window, all you have to do is plug it in and it will blow cool air into the room while the warm air shoots out of the back of the unit and away from the house.
When is Central Air Conditioning the Best Answer?
Central air conditioning may not always be the most practical choice for every home or office. There are some cases, however, when using a central air conditioner is vital to the health of everyone who lives or works in a home or building. The Length of the Hottest Season The biggest consideration for whether or not central air conditioning is the best answer is how long the hot season is in your location. Some areas have a very short hot season that only lasts a couple of weeks. The expense of installing and maintaining central air conditioning may not be worth it if you only use the system once or twice a year. If your hot season lasts for months, though, the use of central air conditioning may feel like more of a necessity than a convenience. The Size of the Building Building size also makes a difference when you consider central air conditioning. If your home or office is relatively small, you may be able to make due with a window air conditioner or a portable air conditioner. If there are more than four or five rooms, central air conditioning may be the best answer. With a central air system you can be sure that every room is cooled equally. When you use other air conditioning systems, their cooling effects can only be felt in the room that they are housed in. If you have a building with a large central room, portable or window air conditioners may not have the power to fill the space the way that central air conditioning could. The Health of the Occupants Central air conditioning is the best type to use if you are trying to keep older or younger people comfortable through the heat of the summer. Any building that houses senior citizens or young children should consider the benefits of central air conditioning to keep their inhabitants safe from the damaging effects of heat. People who are old, young, or in ill health are particularly susceptible to heat. Portable and window air conditioners may work for the short term, but central air conditioning will provide a more even distribution of the cool air.
What exactly is central air conditioning I know I have AC, but what makes it central?
Central air conditioning is an air conditioning system with a central unit that distributes air to the rest of the house through vents. Some people have air conditioning units that are separate for each room, but most houses today have a centralized unit, usually located outside the home, which pumps air to each part of the house through the ventilation system. That is what is referred to as Central Air conditioning, because there is just one centralized unit cooling the entire place, as opposed to many autonomous units cooling each room.
Are portable air conditioning units lightweight?
They are lighter than window air conditioners. But can still be a little heavy. But an average person can still move it to another place in the room.
Ductless Air Conditioners For Better Temperature Regulation?
If you have a home where central air cannot regulate from room to room or floor to floor, ductless air conditioners may be a great option to solve your problem. A ductless air conditioner can be installed in virtually any area of your home. It will provide temperature control for an area that may not stay cool regardless of your thermostat settings. Ductless air conditioners are energy efficient and may allow you to cut back on the use of your central cooling system.
Do wall air conditioners work well?
This all depends on how badly you need cooler air. A wall unit will cool a room pretty well, but not much more than that. However, it can also save you quite a bit of money. Central a/c is more expensive, but will cool your entire house.
How much is it to buy an air conditioner?
The cost of the average central air conditioning unit depends on a number of factors. The brand of air conditioning unit, the size of the room or building that one wishes to air condition, installation charges, and the location of the dwelling are just some of the factors that determine the cost of a central air conditioning unit.
Portable Air Conditioning for Better Cooling Efficiency?
Portable air conditioning can meet the needs for cooling a small apartment, office or a single room. This will make unnecessary, the use of central cooling or the use of a mounted unit in the wall. The portable gives more convenience than a unit that is wall-mounted, since it will cool only one room at any time,and it can also be moved from one room to the next depending on where you need the cooling. Before portable air conditioners were produced, the only way to cool a room was through central air conditioning, which cooled the entire house regardless of whether the entire house needed cooling or not. This resulted in an enormous waste of energy and electric bills that were larger that they needed to be. Even if a wall mounted unit was used, that unit would cool the room it was in only, but it was pulling as much energy as a central cooling unit, and was providing more cooling that was required for just one room. Also, it could not be moved easily from one room to another since it was built into the wall. The big advantage of a portable air conditioner is that it does not need installation and it is ready for use right out of its box. These units are much more energy efficient when compared to other types of air conditioning units and the reduced electric bills will be a welcome change in the hotter summer months. Portable air conditioners are built on a wheel base for easy moving around, and their small size make them easily stored away in small spaces when they are not being used. Cooling capacity of any cooling unit is measured in BTU or British Thermal Units. Portable air conditioners are available on the market in capacities from 6,000 BTU to 60,000 BTU. The portable unit with 8000 BTU can be easily used to comfortably cool a room of 10x12 feet quite quickly. Also, the temperature controls do allow for adjustments of temperatures that will allow customizing of temperatures and so save a lot of energy. Despite its size, a portable air conditioner has the same cooling output as a larger wall mounted unit, and the central air conditioning. Portable air conditioners advantages are that they use less electricity and they are virtually maintenance free.
Where can a person purchase room air conditioners online?
There are many locations where one can purchase room air conditioners online. There are many different models available through Amazon and the Home Depot website.
Why do room air conditioners ice up easier that central air conditioning system?
Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling . The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle. Another reason could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed. A central ac unit is usually out of sight externally to the dwelling or mounted on the roof.
