The earth’s climate is largely controlled by how much of the sun’s light and heat is absorbed and reflected. By absorbing the sun’s heat, trees cool the air. The interaction of this relationship with an area’s topography (地势), latitude (纬度), and altitude, can create microclimate...
Many American homes rely on more than one fuel source to power their homes, such as natural gas or fuel oil for heat.However, almost all of us use electricity for air conditioning, refrigeration, and the myriad electronic devices and high-wattage home appliances that make up the bulk of ...

In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils. When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To ...
The steamy temperatures are likely to have an even more acute impact on cooling costs in the Mid-Atlantic, East South Central and Pacific regions, where energy prices are forecast to increase by up to 12% this summer compared with a year ago. The rising cost of cooling your home is one ...
These services allow a member to rent a car from a central location and pay a small fee for use. The system is ideal for inner-city dwellers who only occasionally need a car, allowing them access to a vehicle without needing to buy one. By using public transportation for their primary ...
"Dialing up" is an effective method of reducing the cost of cooling a house with room or central air-conditioning. The same principles apply: The less the temperature differential the air-conditioning system has to maintain between the inside and outside, the less often the compressor comes on...
Adding central air conditioning to a home with an existing forced-air heating system in a 2,000-square-foot house averages $3,000 - $4,000. If ducts need to be added, the cost can double, and a split unit is the way to go. As opposed to window units, a ductless system is quiet...
Central air unit costs Upfront costs for central air include both the price of the unit itself and the labor to install. You’ll see the most variation based on the size of the unit and whether you need new ductwork. If there’s existing ductwork, you can expect to pay anywhere from ...
