Air Conditioners - Be Cool

Air conditioners these days are such a necessity these days that it is one of the foremost things that comes to mind when you are purchasing household items. Sometimes it’s difficult to imagine what the world will be without air conditioners especially during the summers.

Buying Guide

Here is some advice to follow when buying an air conditioner.

* Take the help of internet and look for review sites that cover branded air conditioners and also their prices. These sites will help you get an idea about the particular item without having to test it out yourself. Also such sites provides a lot of tips to save money while making your purchase.

* You must also check the BTU which stands for “British Thermal Unit” and is defined as the amount of energy required to change the temperature of a pound of water by one degree Fahrenheit. The number of BTUs changes depending upon the capacity of a room. The bigger the room, the more BTUs required.

* Another factor to consider is called ‘venting type’. Window air conditioners are simple and designed in such a way that the proper installation leaves the venting tube outside. This is common in almost all window air conditioner designs. Before buying a unit, you must go through proper research on venting tubes that best suits to your room.

However, choosing an air conditioner is not a difficult task but you should have a little idea about which brand will offer you the best available features in the market. You may also call an air conditioning service technician to provide the proper dynamics for your home.

We often take air conditioning for granted. We simply flip a switch or turn a knob, and finally the house or office temperature drops. Portable room air conditioners offer even greater flexibility when it comes to cooling specific rooms around the house, lowering the heat anywhere you place it.

Although air conditioners come in small to very large sizes, they all function based on the same idea. An air conditioner takes the hot air from inside a building and removes it to outside the building through a hose that is attached to a partially opened window or a hole placed in the wall. A fan is used to bring the hot air in the room into the air conditioning unit, and that hot air flows over an evaporator coil. The coil is filled with refrigerant, which absorbs the heat from the air. Now that the air is cool, it flows back into the room through the front air vents on the air conditioner because a fan pushes the cool air out. The heat leaves the room through the hose vent to the outdoors, or to a second section of the unit, which is found in a split unit.

Some air conditioners are also dehumidifiers. This means that the unit takes the excess water from the air in the room, making the effects of high humidity lessen. The water taken in also helps to cool the unit. The unit can cause the water to evaporate due to the hot air taken in, and this type of air conditioner has no tank that will need to be emptied. Other units use the condensed moisture to improve the unit’s efficiency, in a method called condensate cooling.

Some air conditioners also function as heaters, thereby providing two useful traits for the price of one. All air conditioners help improve air circulation in sluggish room air. Other units offer filtering options for pollen, dust and dander, which is very helpful to people with health issues such as allergies or asthma.

Portable room air conditioners are available with any of these functions, so you can pick the one that will best meet all of your room air needs.

Today many people save themselves from this unusual climatic condition, so as many people also depend a lot on air conditioners. Buying a split AC (air conditioner) or a window AC, the most important thing is to know whether they will perform smartly under tough circumstances. Since, we tend to overuse the air conditioners during the summer, we need to be prepared for their maintenance just incase they fail to perform up to the desired level. Take a look at some of the maintenance tips for split Air Conditioner that should be applied to boost the efficiency of your split air conditioner.

The smooth functioning of a product depends on its proper maintenance. So, if you have a product, then you need to take good care of it. In case of an AC whether domestic or commercial, the following points should be noted for better performance and durability of the product. The various components of it include:

1. Air conditioning filter is an important part of an AC. It should be changed every month or every two months regularly depending on its use. If not the air would be dirty and filled with pollutants. The dirty air conditioning filters also increases the air conditioning repair and maintenance cost.

2. Another important part is the compressor. It compresses low pressure, low volume gas making them the high pressure, high temperature and the gas needed for the AC. It also removes vapor from the evaporator to maintain a low boiling point. Make sure to clean the compressor regularly to get cool and refreshing air. Oil specially designed for the Air Conditioner can be used for its longevity.

3. When air passes through the system, the evaporator coil absorbs the heat to provide cold air through out the space. Replacing the old evaporator coil improves the air flow and air circulation inside the home.

4. Air conditioning maintenance also includes cleaning of air ducts or ducts. In the air conditioning system, air ducts are spread through out the entire house keeping the area cool and pleasant. Hence, the ductwork ought to be cleaned regularly to remove the dust collected on air ducts.

5. All air conditioning system use refrigerant to absorb the excess heat and supply cool air inside the house. Sometimes there might be a refrigerant leak. So, a reliable air conditioning company or contractor should be called to check and repair that part.

Although the running cost of both window and split AC is almost the same, the power consumption of a split AC could be little higher because of the additional motor it requires. Moreover, the capital expenditure of it is a bit higher than the window AC as well. A split air conditioner scores higher than a window air conditioner because of its ‘silence’ feature. The compressor of a split air conditioner is kept away from the indoor unit and thus, ensures complete silence inside your room.

It’s pretty surprised to know that buying a big air conditioning unit for your bigger room won’t necessarily make you feel more comfortable during the hot summer months. In fact, a bigger room air conditioner area is supposed to cool will perform less efficiently and less effectively than a smaller or properly sized unit.

Depending upon the room units it will work better if it run for relatively long periods of time than if they are continually, switching off and on. Longer run times allow air conditioners to maintain a more constant room temperature. Running longer also allows them to remove a larger amount of moisture from the air, which lowers humidity and, more importantly, makes you feel more comfortable.

Sizing is equally important for central air-conditioning systems, which need to be sized by professionals. If you have a central air system in your home, set the fan to shut off at the same time as the cooling unit (compressor). In other words, don’t use the system’s central fan to provide circulation, but instead use circulating fans in individual rooms.

Cooling Tips

• Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic. They are effective when operated at night and when the outside air is cooler than the inside.
• Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
• Don’t set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
• Set the fan speed on high except in very humid weather. When it’s humid, set the fan speed on low. You’ll get better cooling, and slower air movement through the cooling equipment allows it to remove more moisture from the air, resulting in greater comfort.
• Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.
• Don’t place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
