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.

HVAC Noise: Solving a Common Noise Problem

Noise pollution caused by rooftop and ground-level HVAC equipment including chillers, boilers, and air handlers has become one of the most annoying as well as dangerous environmental problems in cities worldwide. As urban noise increases and residential growth multiplies, residents and communities are demanding better noise reduction solutions for heating, ventilation and air conditioning equipment. Outdoor community noise problems caused by commercial and industrial HVAC systems may require an acoustically engineered Sound Barrier Wall.

Sound barrier walls have been used extensively for years in the transportation and industrial fields. A sound barrier wall is an exterior structure, normally made of masonry or earth, designed to protect sensitive land uses, such as residential areas from noise pollution. These noise pollution abatement products are now being used to help eliminate unwanted noise from HVAC systems as well.

Traditional material for noise barrier walls for HVAC systems has been reflective products. Reflective products, like concrete or brick, simply redirect the unwanted sound waves in other directions, and can actually increase noise by unintentionally reflecting sound waves. There is a better solution. Absorptive sound enclosures and architectural screens actually absorb the unwanted sound waves, minimizing the risk of unintentional reflected noise. Absorptive sound walls reduce reflections and are able to maintain the effectiveness of the barrier. Therefore, the overall noise level is reduced. The advanced materials found in absorptive barrier walls present a much more effective noise barrier solution. There are different solutions for this problem such as the LSE System, an absorptive sound barrier created by Sound Fighter Systems, that actually absorbs the sound waves that hit it, thereby eliminating unwanted noise.

So, if you are facing problems with noisy HVAC equipment an absorptive sound barrier wall is obviously the most effective noise mitigation solution available for this very demanding application. Absorptive walls outperform and outlast all other noise reduction products. Plus, many systems such as the LSE System are an aesthetically pleasing HVAC sound wall with the added benefit of noise pollution reduction.

Murray Stacy is Vice President of Sound Fighter Systems, LLC, which has been researching, designing and manufacturing highly efficient absorptive noise barrier walls since 1973, making it the oldest established manufacturer of such products in America. Sound Fighter walls have been produced for unique noise mitigation applications around the world, and several of the company's walls are in their 30th year of effective service. http://www.soundfighter.com
