Adjust The Thermostat Levels To Increase The Efficiency Of The Air Conditioner

Be it the hot and scorching summer months or the cold and chilly winter months, it is hard to imagine life without an air conditioner. There are several issues that we need to consider before buying an air conditioner. This would include the make of the air conditioner, the capacity of the air conditioner, the room you would be installing it in, etc. There is also the issue of efficiency of an air conditioner linked to the choice you make.

The efficiency of an air conditioner is important to many people as the running costs of an air conditioner is generally pretty high. With a lower efficiency air conditioner, these costs could sky rocket. However, there are a number of things we can actually do to increase the efficiency of the air conditioner.

The first thing that we need to do is take proper care of the device. Maintaining the air conditioner and its different parts in prime working condition ensures that the unit will work at its optimal level and be more efficient.

Similarly, if we keep the room from heating up too much from the rays of the sun by drawing the curtains, we can further increase the efficiency of the air conditioner.

Another very effective way to increase the efficiency of an air conditioner is by adjusting the thermostat levels of it. By setting it at proper levels you can save significant amount of power consumption. During the summer months try and adjust the thermostat levels at 78 degree Fahrenheit or higher. If you adjust at any lower temperature, you will be spending about 7% extra on your electricity bills for every additional drop of Fahrenheit degree temperature.

Similarly during the winter months adjust your air conditioner?s thermostat level at 68 degree Fahrenheit or below it. This will again save you a lot of power consumption and hence cooling costs.

If you are not used to such temperature in either of the seasons, then it will take time for you and your family to adjust. Don?t just rush into it. First let your family know why you are adjusting the thermostat levels. Then reach the level gradually by changing the thermostat temperature every day by a degree. This would help you and your family to acclimatize better. And in no time you will be saving a lot of extra bucks on your electricity bills. You can even plan for something with those extra dollars to reward yourselves for sticking to the plan.

A Few Words On Central Air Conditioners

Although there are quite a few variants of air conditioners available in the market today, it is being observed that the central air conditioners are increasingly gaining popularity even for domestic purposes. It is a fact, that the central air conditioners have ruled the roost as far as commercial air conditioning goes. Now that they are making inroads in the domestic market also is significant.

Besides the general effects of air conditioners of keeping you cool and comfortable, central air conditioners have also been positioned by their manufacturers as partial air filters and dehumidifiers. Now if someone in your family has minor problems of allergy or asthma, then installing a central air conditioner can be of help.

Before you get yourself a central air conditioner installed in your house, you need to know exactly what capacity of air conditioner you will require. With other kinds of room air conditioners, knowing the dimensions of the rooms can be good enough. However, since the central air conditioner will be for the entire house, calculating the capacity of air conditioner you will require should be best left to an expert. You can call a contractor and take inputs from him. Any contractor would use , what we call the ?manual j? method to determine the size of the air conditioner you will require for your house.

When you actually shop for a central air conditioner you should consider two ratios, the Seasonal Energy Efficiency Ratio (SEER) and the Energy Efficiency Ratio (EER). These ratios will tell you how efficient your air conditioner really is. Since most modern air conditioners come with SEER ratio higher than 13, you should settle nothing less than that. Even the EER ratio should be around 12.

There are still a few negatives to the central air conditioning system. First of the installation is costly and it is also a lot of hassle. There need to be provision for installing a central air conditioner, the network of ducts has to be perfect so that all the areas in the different rooms are evenly cooled. The central air conditioner is also much less energy efficient than the room air conditioners. It cools the entire house even though all the residents of the house are in a single room.

So think before investing on a central air conditioner and weigh your options. If you find it is a worthwhile investment then go ahead and get yourself one.

How To Get The Most Out Of Your Air Conditioner

Your basic air conditioner continually takes air from outside, cools it, and then returns it to one or more rooms within your house. A properly installed air conditioner can cool up to fifty cubic tonnes of air each year. Read on to learn more about these remarkable machines and how they can add value to your home.

1. Choosing Your Air Conditioner

The back yard is the most common place to find a central air conditioning unit. One reason to choose a free standing unit over the more poweful central air system is that it can be brought with you when you move.

During the cooling season, clean the filter on a room air conditioner every 30 days. This lets more cool airflow into the room and reduces airborne dirt, lint and pollen. Keep your air conditioner out of direct sunlight and seal the window to reduce air leakage.

2. Both Units Can Benefit From A Cover

A solid investment is a cover for your central air system. Not only will it keep debris like snow and leaves out, but it will significantly extend the life of your unit. Some covers are also designed to minimize noise.

Don't set your thermostat to a cooler temperature setting than normal when you first turn on your air conditioner. Your home will cool no faster and you will end up wasting energy.

3. The Importance Of Changing Your Filter

Even if you don't need an air conditioner for feeling cool in the summer, you can still put one to good use. Conditioners will filter the air through, well, a filter, and this can be a great boon to anyone that has a baby, has asthma, or suffers from allergies. Dust slowly collects inside the filter that must be changed once every six months. If you do not change the filter regularly it can cause your air conditioner to not work anymore. In addition, you and your family might not be breathing clean air.

Buy a Room Air Conditioner That is Right For Your and Your Family

Follow these tips and buy an efficient, durable air conditioner to keep your home and family cool and happy.

If you don't have central air conditioning in your house, you may already know that the cost to install a central air conditioning unit is expensive and the installation can be a nightmare. These units can cost $4,000 to $10,000 to install depending on the size and configuration of your house and the available ductwork.

If you decided to consider a room air conditioner instead, you are like millions of others who opt for the simple, less expensive route to cooling their home during the hot summer. But there are so many room air conditioners out there. The choices are confusing!

Before you buy an air conditioner, consider where you want to put the unit. A room air conditioner is vented through a window or a hole in the wall, so you will need a suitable sized window OR clear wall space where you can cut a hole to vent the unit to the outside. Consider the cost of having a carpenter cut a hole in the wall and insulate it so that you don't lose air around the unit during the winter.

Next, you need to think about the square footage you want to cool with your air conditioner. The unit you need for a small bedroom is different than what you will need to cool a living room or family room.

The capacity of a room air conditioning unit is measured in BTUs (British Thermal Units) to tell you the size of the room that air conditioning unit will cool. Measure your room or cooling area before you go to the store to buy the air conditioner.

If you are looking at a used air conditioner, be sure you check the age of the unit, its BTU rating AND the efficiency of the air conditioner. Old units are not efficient in their use of electricity. You may save something on the purchase price, but it will cost you a lot more in electricity over the year.

Some new units also have automatic thermostats to turn off the air conditioner, as necessary to keep the room temperature constant.

Check the environmental efficiency rating on new units versus the used air conditioner you are considering. You want to look for environmental efficiency to be sure that the unit does not damage the ozone layer.

You should also check the available warranty on the air conditioner you buy. Check to see what parts and major components are covered by the warranty and for how long.

Less expensive air conditioning units may cost you more in the long run if the parts and major components are not covered by a good warranty. Reputable brands cover major components for ten years, and warranty smaller parts for 1-5 years.

Reduce the electricity cost to run your air conditioner by keeping your blinds and drapes closed on hot days. This helps to reduce the build-up of heat in your house so your air conditioner does not have to work as hard or as long.

Clean the vents and filters on your air conditioner as recommended by the user manual, to ensure that your air conditioning unit is running at maximum efficiency.

How Air Conditioners work?

Air Conditioners: In an Air Conditioner chemicals are used to cool the temperature of the room. The liquid chemicals are produced from a gas, which again converts to gas form. The chemical transfers the heat from the inside to the outside of the room.

Mainly the Air Conditioner machine has three parts, a compressor, a condenser and an evaporator. The condenser and compressor are in the outside portion of the machine while the evaporator is located inside the room.

In the processor the chemical, which is a low-pressured cooled gas, enters. The processor then squeezes that chemical. It makes the molecules of the chemical closer together. The closer molecules create high energy and heat. The chemical leaves the compressor as hot and high-pressure gas and enters the condenser. At the backside of the machine we can see a metal fin. It works as a radiator and helps to cool down the heat very quickly. When the chemical leaves the condenser, it become very cold. The liquid flows in the evaporator through a small hole. On the other end the chemical becomes colder and starts to evaporate to gas. As the liquid becomes gas it soaks heat from the surrounding area. The heat of the air is needed to separate molecules of the chemical, which were packed together in the processor. The evaporator also has metal fins to exchange cool temperature with surrounding air. The liquid again leaves the evaporator and begins the same process. A fan connected with the evaporator circulates the cool air into the room.

HVAC Training

With strengthening modern technology, HVAC training is more necessary today than ever! While many will train for a career in HVAC (Heating, Ventilation and Air Conditioning) while on the job, more and more employers are now searching for graduates who have successfully completed their post secondary HVAC training to fill the ever-increasing demand for skilled technicians.

In an HVAC training program, students commonly learn to read blueprints; they also learn about safety issues, tools of the trade, designs, equipment construction, electronics, and the installation, maintenance and repair of heating, ventilation and air conditioning systems as well as heating and refrigeration systems. Additional coursework may include applied physics, chemistry, computer applications, electronics, and mechanical drawing.

A suitable HVAC training program is usually administered at a vocational or trade school, but there are some online HVAC schools, as well. Students are taught how to troubleshoot, repair and maintain heating, ventilation and air conditioning mechanisms and entire systems. Future HVAC technicians may evaluate settings and adjust system controls, test equipment, install fuel or water lines, and install air ducts, pumps, vent systems and other associated parts. In addition, prospective technicians learn how to connect electrical wiring and other components necessary for optimum HVAC operation.

Students who complete in HVAC training may earn a certificate or college credits. Furthermore, those who have fulfilled requirements for becoming an HVAC technician can expect a promising career outlook as the projected rate of available jobs is increasing more rapidly than many other occupations. While earnings vary, the top ten percent of HVAC technicians make more than $27 per hour.
