How Air Purifiers Work

Americans spend an estimated $250 million annually on air purifiers for their homes, with asthma and allergy sufferers responsible for most of the sales [source]. But scientific studies and testing reveal that many purifiers aren't effective at all, and some may be causing harm. The notion of purifying air has merit, however. The air inside the typical home is generally dirtier than the air outside, because a house can be a source of air contaminants. Moisture can lead to the development of mold and mold spores. Forced-air heating and cooling systems circulate dust particles and bacteria throughout the house. Pets shed fur and give off dander, while smokers pump toxins into the air. Pollen and other outdoor allergens can blow in through open doors and windows (or through a window or door screen) and become caught in carpet or upholstery.

What is Residential Air Conditioning?

There’s nothing like residential air conditioning to relieve the discomfort of heat and humidity in tropical climates, or during the dog days of summer. This cooling process is accomplished by a home air conditioner. A residential air conditioning unit is commonly a window- or wall-mounted unit, a central air conditioning system, or a ductless, mini-split set-up. Each type of residential air conditioning system is designed for a specific purpose; such purpose is dependent on the cooling capacity of the particular unit.

Top Ten Things About Air Conditioning

Most homes in warm climates have air conditioning. For some, air conditioning may be a luxury, but for many, it is a necessity. Given the expense of the equipment and the power to run it, ASHRAE wants consumers to be informed about their air conditioning systems. These ten points should make a consumer more aware of the air conditioning system and better able to care for it and use it well. Should it become necessary to replace that system, seek out a qualified HVAC professional.

Buying, Fixing & Installing a Central Air Conditioner

Are multiple room air conditioners causing your electricity bills to skyrocket? Or, perhaps worse, is your house virtually unlivable during summer because of the heat and/or humidity? Maybe it’s time to consider central air conditioning.

Central air conditioning, also called “central air” in the United States and “air-con” in the United Kingdom, is a system that cools more than one room in a house (in most cases, the entire structure).

Protect the thermostat for your heating or cooling system from anything that would cause it to give a false reading. If the thermostat is in a draft, misplaced on a cold outside wall, or too close to a heat-producing register, its accuracy will be compromised.

Optimizing Your HVAC System

Optimizing your HVAC system can lead to a lower gas bill during the colder months of the year. Year after year, and during winter months, people use heating sources almost all day long to keep offices, stores and homes under comfortable temperatures. Leaks in HVAC will cause your system to run longer and sometimes the desire temperature inside can not be reached.

What Is a Remote Thermostat?

Temperature control via a thermostat can be convenient with the use of a remote thermostat control. How nice would it be to be able to control the thermostat in your house from a computer anywhere? Then again, you can also control these with the use of a telephone.

Have you ever left the house for a trip or vacation and wondered if you had turned the thermostat down? Instead of heating or cooling the home while you're gone, turning the temperature back would be ideal. Now, with the invention of a remote thermostat control, you can control or check the temperature of the home from virtually anywhere. Any touch-tone phone becomes your access to temperature control.

How Air Conditioners Work

The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking techniques of the time. Carrier treated the air inside the building by blowing it across chilled pipes. The air cooled as it passed across the cold pipes, and since cool air can't carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature -- and a new technology was born.

How to Power Wash a Wood Deck

Guys seem to love equipment that makes noise, is powerful and saves time. A power washer can fit that bill just fine. But it can also ruin your wood deck! Why? Because most people don't use the power washer properly and use it with too high a jet pressure (that's the "power" part) and place the tip too close to the soft wood.

A power washer can be powerful enough to etch brick or gentle enough to wash siding. They come in various sizes, some providing over 4,000 psi (pounds per square inch) of water pressure some only a few hundred, some are run by gas engines, some by small electric motors, they have a variety of pressure wand tips and can handle many different tasks.

Tips: Heating and Cooling

Heating and cooling your home uses more energy and costs more money than any other system in your home -- typically making up about 48% of your utility bill.

No matter what kind of heating and cooling system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. But remember, an energy-efficient furnace alone will not have as great an impact on your energy bills as using the whole-house approach. By combining proper equipment maintenance and upgrades with recommended insulation, air sealing, and thermostat settings, you can save about 30% on your energy bill while reducing environmental emissions.
