The Simple Guide To Saving Big Money With Your Air Conditioner

Depending on where you business or home are located a air conditioner might be a necessary evil and something that you just have to use and don't have a choice about. However there are some simple things that you can do to cut costs and save a good deal of money. Below you will find some simple to follow steps for getting the most form your air conditioner.

Always On? Air conditioning doesn't always have to be on. The first thing you have consider when maintaining an air-conditioning unit is that it doesn't have to always be on. You can schedule the air-conditioning to be turned on during peak hours when the weather is too hot. If you have more than one unit you could rotate them to function depending on their need.

During some parts of the day you only need one or two units to keep the building comfortably cool. And during noontime, you may need all of your units open. Just make sure you study a workable schedule that optimizes the use of your air-conditioning units.

Regular Maintenance Regular maintenance can greatly increase the performance of your air-conditioning units. While regular maintenance may seem like a cost increasing method, it actually reduces the cost of operations for your air-conditioning units. This is because air-conditioning units that aren't well maintained don't perform as well as those that are.

A decrease in the air conditioners performance means it eats more electricity just to arrive at the same temperature than it would normally need. That is why cleaning and maintaining an air-conditioning unit is vital to saving money on their use.

Turn Off Early Always turn off the air-conditioning unit 30 minutes before leaving the building. Some people turn off their air-conditioning units just as they are about to leave the building. The fact is, you can turn off your air-conditioning units a good while before you leave. That is because it takes about 30 minutes for the temperature of the room to go back to being uncomfortable.

The Right Air Conditioner Choose the right kind of air-conditioning. Choosing the right kind of air-conditioning for your room and saving money on electricity costs are synonymous with each other. If you are trying to air-condition a small room, then a smaller horsepower air-conditioner would be sufficient. If you install the larger more energy hungry air-conditioner, you would spend more than you need.

It is important to keep the cost of your air conditioning habits in mind and always try to think about ways you can save money on it's usage. Simple turning it off 30 minutes before leaving work for the day and not using it in the morning can help save a good deal of money. Also making sure that the unit you own fits well with your needs and specific requirements can be a huge help.

Air Conditioners And Health Issues

We are so concerned about the comfort that air conditioners provide us that we hardly ever look at what kind of health implications the air conditioners might have. However, if we spend some time on the topic, we can understand that air conditioners can be considered both as a boon and a bane, depending upon the circumstances. Let us consider the positive health implications of an air conditioner first.

These days air conditioners have a much improved technology and the basic principle in which it functions allows it to significantly improve the quality of the air. Through the various processes like filtration, humidification, cooling, disinfection etc. the air conditioner actually provides us with a much cleaner and safer air to breathe. So someone having severe allergic problems, would be much better of in a room air conditioned. People suffering from asthma would also be benefited. Even for operations that are conducted, the air conditioner allows a climate where the infections can be controlled and the environment would be safe for the patients. Without air conditioners, many critical operations would have been just too risky.

Places where we have severe heat waves, air conditioners can actually save the lives of the elderly. In fact, local authorities at many places actually build facilities with air conditioners so that those without ones can actually seek refuge in one of these shelters during the time of an acute heat wave.

However, air conditioning can also be held responsible for a few health problems. If the central air conditioning system in an office or in a home is not properly maintained, then it can actually facilitate the spread of microorganisms. These can include Legionella pneumophila, a microorganism responsible for Legionnaire's disease.

Air conditioning units can generate sounds to which when someone is exposed over a considerably long period of time can lead to the individual?s hear loss. To provide an analogy, being exposed to the sound of an air conditioner constantly is like living near an air port or a busy highway.

There have also been claims, that excessive use of air conditioners can actually cause someone to grow fat. Some researchers maintain that with regulated temperatures our body stops adjusting to the temperature changes and since there is a cessation of effort on the part of our body we burn less calories and hence more fat gets accumulated. Such claims need to be clarified better.

Cars And Air Conditioners

We are so used to the concept of an air conditioner that we hardly take notice of it. That is only until it stops working. And then we have a serious issue at hand and at times we are clueless as to what exactly the problem is and how to tackle it.

The air conditioners have become so integral to our lives that we cannot think of living without it. First it came to our offices and factories. Then we brought them to our homes. And now we have them even in our cars. Come to think of it, it is actually essential to have an air conditioner in your car. Of course the interiors of a car is more affected by the heat of the sun than the interiors of your house or office are. And there would be additional heat from the engine to deal with. So it is quite necessary to have a car air conditioned. And it is equally important to see to it that you take proper care of the unit so that it delivers when you need it to and doesn?t break down.

It has been seen these days that to repair older air conditioners it is costing one a few hundred bucks more than it used to. This is primarily because of the regulations that have brought about a change in the refrigerants being used. The previously used R-12 refrigerant, popularly known as Freon has been replaced by R-134a. This is considered to be environmentally safer.

Since you cannot mix the two kinds of refrigerants, so any repair now would mean that you have to flush out the existing refrigerant and fill it up with the newer approved refrigerant. This will obviously increase the costs of fixing your car air conditioner.

The best way to avoid costly repairs would be to check the auto air conditioning system once every year. There are many automotive service station which would provide special check-ups before the summer seasons. You can also go for a bundle check-up where your entire car, including the air conditioner is fine tuned. This would also cut down your maintenance costs.

Since having an air conditioner in your car is a sizeable investment it would be prudent to have it functioning properly. If that would mean regular check-ups then so be it. And it is only once a year. So it shouldn?t be too much of a problem.

Air Conditioner Buying Guides

It's that time of year again. If you don't have an air conditioner you may be thinking of getting one. If the one you do have seems to be less than adequate, it may be time for an upgrade. What should you look for? Many consider buying an air conditioner a confusing process. Why not take a minute to read up on what's available and what all those numbers mean.

Points to Remember before Buying Air Conditioner:

* First, BTU stands for British thermal units per hour. Really, all that one really needs to know about this is that the higher the BTU, the more space the air conditioner can cool efficiently.

* The aim is to get as many BTU's as necessary for sufficient cooling without getting a unit that is more than you need. As a general room of thumb, look for five to six thousand BTU's for each 100 to 300 square feet you want to cool. Consider seven thousand to eighty two hundreds BTU's for 250 to 55o sq. ft. and ninety eight hundred to twelve thousand five hundred for area that is 350 to 950 sq. Expect a standard air conditioner to cool one or two rooms.

* One of the most important steps is to consider the need and matching that to the most effective solution. Is the air conditioning needed for the entire house, or mostly for a single room? Additionally, how often will it be used? If air conditioning is only needed occasionally for a small area, a temporary in-window model might be more appropriate, as it can be removed when not necessary. On the other hand, if permanent air conditioning is needed for the entire home, a larger solution might be needed.

* With an idea of the type of air conditioner needed, it is important to consider energy costs. Air conditioners can use significant power, and some units are more energy-efficient than others. Comparing models to find one saves energy while still performing effectively can save a significant amount on monthly power bills.

* Check the labels: most list the capacity of the model in British Thermal Units (BTUs) and give an idea of how energy-efficient the unit is. The more British Thermal Units, the greater the capacity of the unit. Additionally, some utility companies offer cash incentives to customers purchasing energy-friendly appliance replacements. Energy costs can make a huge difference when considering different air conditioners.

* Of course, the price of the unit itself is a consideration as well, and it is important to shop around to get a good deal. However, the price of the unit itself should not be the only consideration. When comparing prices, it is important to factor in the cost of delivery and professional installation, if required. In some areas, product discounts and faster installation may be available in colder months when demand for air conditioners is lower.

* When properly researched, purchased and installed, shopping for an air conditioner need not be difficult. Air conditioning can make a home more comfortable as well as more appealing to some home buyers. By considering needs and shopping around for a good deal, buyers can make a smart decision.

Air Conditioner Thermostats

A thermostat is an apparatus for maintaining the temperature of a system within a particular range by directly or indirectly controlling the flow of heat energy into or out of the system. All air conditioners have thermostats that can be manually operated or automatically preprogrammed to work at regulating the room temperature. There are many ways in which you can use an air conditioner thermostat effectively.

One of the most successful yet economical ways to reduce your air conditioning costs is to adjust the thermostat setting on the air conditioner. The savings are more noteworthy when you set your thermostat at 78 degrees Fahrenheit or higher. For each degree you raise the thermostat setting, you reduce seasonal cooling costs by 7 percent to 10 percent. In doing so, you can use ceiling fans in addition to the air conditioner and thus, save a lot of money.

Most centrally located air conditioner thermostats are equipped with two fan settings, 'on' and 'auto'. When the thermostat setting is set to 'on' the fan runs constantly and when it is set to 'auto' the fan runs only during cooling cycles when the air conditioner compressor is in use. When the air conditioner is in use all day, the cooling compressor only operates about 50 percent of the time, that is, for about 12 hours. The extra fan operating time that occurs when the thermostat is set to 'on' can add roughly $25 to monthly air conditioning bills. Using the 'auto' setting, alternatively, saves energy and money because the fan operates fewer hours. Besides achieving energy and cost savings, the 'auto' setting also promotes more comfort by offering better humidity control as moisture removed during the cooling cycle is re-circulated back into the home while the compressor is off.

Thus, thermostats play an important role in the cost and function of an AC.
