Air conditioning is a system that introduces cold air into a hot space to make it more comfortable. Air conditioning typically is used when temperatures are above 70 degrees. It is used in cars, houses, offices, retail stores, restaurants, and other indoor facilities. Unlike heat, air conditioning is considered a luxury, and it is possible to go without it. Heat is considered to be a necessity and all homes must have it. When heat warnings exist, however, lack of air conditioning can present a problem for many elderly people who may live in older brick homes. Without air conditioning, these types of homes literally turn into an oven at a certain temperatures and can cause death.

Alternatives to air conditioning are fans, either electric or handheld, or open windows. Air conditioning is used primarily in the summer when temperatures are higher. Therefore electric bills are usually higher in the summer months. Many electric companies offer budget billing, which balances out the high and low bills into a constant monthly payment. Budget billing is based on usage and may gradually increase over time as usage goes up.

There are two types of air conditioners that are primarily used in homes. Window style units are placed in a window. Window air conditioning mainly cools the room that they are placed in. More expensive units may cool off more of the surrounding rooms. Window air conditioners run on electricity. They are placed in windows because the heat in the room is passed outside and swapped with the cold air coming in. Alternatives to window air conditioning units are wall air conditioners, which do not need to be placed in a window. Window units are more common in older homes.

New construction typically has central air conditioning built in. Central air conditioning runs the air throughout the entire house with the actual unit located outside. A thermostat controls the temperatures of the house. Older thermostats need to be changed manually to the desired temperature. Newer thermostats are programmable. Temperature settings can be programmed to change at certain times of the day. This can help lower electric bills by allowing the house to be warmer when the house is empty. Running central air conditioning uses a lot of electricity but it is generally more energy efficient than window air conditioning. Many older homes use either window units or have no air conditioning at all.

Air conditioning is available in most new cars today as well. In extreme heat, air conditioning provides considerable comfort on a long car ride. In cars operating without air conditioning, one can roll the windows down to let wind blow in. Wind, however, is not as comfortable, and can be noisy, especially if driving on the highway. After a period of time, air conditioning may not work as well. Sometimes recharging the freon gas will help improve performance. Other times, the air conditioning may need more extensive costly repair work. Many times people will choose not to fix the air conditioning in their cars when the cost outweighs the remaining value of the car.

With new technology comes improvements to air conditioning systems. As time goes on, air conditioners will become more energy efficient.

So you have decided to buy central air conditioning.

Almost eighty percent of the new U.S. houses are installing central air conditioning units while construction. While it may not have been necessary to have air conditioning several decades ago, it is quite uncomfortable not to have it now. But those having existing homes do not need to worry, as the central air conditioning units can even be set up in houses that have already been constructed!

If you are looking for the best central air conditioning unit, you need to keep certain points in mind.
The best way and most important thing when buying central air conditioning equipment is to have it installed by a qualified contractor.
When one talks about saving money through efficient air conditioning systems the topic of SEER usually comes up. SEER or seasonal energy efficiency ratio, rates the central air conditioning unit. You can actually save quite a lot in your electricity bills if you substitute your old and ineffective air conditioner with a new SEER rated central air conditioning set up. Heating, ventilation and air-conditioning (HVAC) manufacturers are responding to the challenges of increased energy costs by offering homeowners air-conditioning units that deliver new energy efficiency standards and reduce your energy usage.

Always consult a specialist engineering company, who will specify, design and install the correct air conditioning system for your needs. There are many reputable contractors specializing in the installation of air conditioning systems for both small and large homes. Large houses usually require a centralized air conditioning system and its installation is more complicated and labor intensive. There are various kinds of air conditioning systems depending on your needs, your home size and your budget.

Choosing Your Air Conditioner And Installer

There are a number of reasons why you should go for central air conditioning.
It is the most effective way of heating and cooling the entire home because it can supply the conditioned air directly to the rooms whether the internal doors are open or closed. Having said that, which brand or manufacturer should you consider? Good question, but in reality it depends on your budget and your expectations. It would be recommended that you retrieve at least 3 quotes from reputable businesses (not outlets like Home Depot) which specialize in air conditioning supply and installation.
These companies will have ties to certain manufacturers and as a result will push a brand they will make more money from. But if you are aware beforehand which brands you are interested in you will be more assured of getting a good deal on a system you have chosen not what they want you to have.

The back yard is the most common place to find a central air conditioning unit condenser unit (outdoor section). This information is important because a house’s structure, window area, sun exposure, and climate will affect your central air conditioning needs. Again this is where you need specialist guidance from experienced installers. Make sure they look all over your home checking each room you want diffusers (ceiling outlets) in and note whether they check out the ceiling space, this small check is important as seasoned quoters / installers with experience will tell you that some ceiling spaces do not accommodate the ducting very well and can cause all sorts of difficulties during installation, you do not want the installer cutting corners (so to speak) trying to fit ductwork.
The electrical load on your home will be increased dramatically as a central A/C system is a large electrical user, some homes cannot accommodate this requirement and therefore need to have their mains upgraded. This can significantly increase the installation cost.

Maintenance Of Your Air Conditioning System

For your home central air conditioning system to last as long as possible, proper maintenance is a must. You probably recognize – as most homeowners do – that keeping your heating and air conditioning units running well is important. We tend to take our air conditioning for granted, and wonder how we ever got along without it, but we rarely check the system until it begins to blow out hot air.
Proper care of your air conditioning system like scheduled cleaning will also make it more efficient for a long time. If you have central air conditioning, it is important to keep the outside compressor compartment (condenser) as clean as possible. And of course the indoor return air filter must be kept clean also to improve the air flow throughout the home. There are not really many things the homeowner must do to keep their A/C happy other than cleaning and keeping the outdoor condenser free from debris and plant foliage.
If you do these you should receive many years of faithful service from your new central air conditioning system.
