This summer's sweltering heat wave made many homeowners long for central air-conditioning - a luxury in a city where most houses were built before the World War II. These older homes typically use steam or hot-water radiators for heat and are built of solid brick or stone, which makes it difficult and costly to install the bigger, 12-by-28-inch sheet-metal ducts used for conventional central air-conditioning systems. Many all-electric homes built in the '50s and '60s have a similar problem because they were built with radiant baseboard heat.

A four-alarm fire that caused about $500,000 in damage early Friday to the Llanerch Country Club in Haverford Township was caused by a malfunction in an air-conditioning unit in the clubhouse ballroom, a county official said. George Lewis, Delaware County Fire Marshal who investigated the fire, said it erupted about 1:45 a.m. in the back of the ground-floor ballroom and engulfed a wooden structure surrounding the air-conditioning unit before spreading to areas next to the ballroom.

Come what may in the waning weeks of summer, most of the Philadelphia region and the rest of the nation are armed to the teeth against an outbreak of heat and humidity. Philadelphia may not be in a climatic league with Houston or Miami, but in the eight-county area two of three homes have air conditioning, according to the U.S. Census Bureau. Philadelphia-area figures are comparable to national figures. Not surprisingly, the highest concentration of air conditioning is in the Southern United States, where more than 85 percent of homes have central air conditioning or window air conditioners.

Question: The ducts for our central air-conditioning run through the attic and the registers are in the ceiling. It seems that cold air comes out of them in the winter. Is the chilly breeze my imagination? Answer: It most likely is not your imagination. The air inside the air-conditioning ducts in your attic gets cold and becomes dense. Since it is heavier than the air inside your room, it drops down and you feel it. This can create a substantial energy loss and make you uncomfortable.

In 1949, Harold E. Stassen, then president of the University of Pennsylvania, faced a tough decision. The Dietrich family (Ludens cough drops) had provided money to help finance construction of a new Wharton School building. The question was: Should it be air-conditioned? Systems that cooled the air indoors were fairly common even then. The U.S. Capitol had been air-conditioned in 1920, and New York's Rockefeller Center in 1932. But money for university expansion was tight in the immediate postwar years.

The Council Rock school board Monday night just said no to a $3.5 million bond issue to outfit several of the district's elementary schools with air conditioning. But the district is still considering a bond issue that could total as much as $62.6 million to pay for two new schools, a new administration center, land for future building, asbestos removal and improvements to schools. Assistant Superintendent David P. Blatt presented the board with a list of possible projects, based on a 1988 study of the district's 12 schools by the architectural firm Faridy, Thorne & Maddish of Trenton.

The Washington Township school board has voted 5-3 to install $410,000 worth of air conditioning at two new upper-elementary schools, Heritage Valley and Pitman Downer, and at Hurffville Elementary School. On Aug. 23, board members agreed to install the air conditioners during construction, rather than simply installing ducts so that air-conditioning systems could be put in later. The upper elementary schools are under construction, and the elementary school is being renovated.

The air conditioners cooling downtown office buildings are also making sweltering streets even hotter in cities across the country, researchers say. Anyone who has felt the hot blast of an air conditioner's exhaust knows how that happens, but new research suggests that the waste heat from air conditioners can add as much as two degrees to outdoor urban temperatures. For cities already suffering elevated temperatures due to hot roofs, hot pavement and little greenery, using air conditioners makes matters worse, if only for those not cooled by them.

It's only June, not officially summer yet, and already it's been broiling hot. If this keeps up, there's little doubt that we'll all see our electricity bills spike. Rising gasoline prices will probably mean fewer escapes to the Shore or the mountains. And for those on fixed incomes, the cost of keeping cool may stretch finances to the limit. With that in mind, and with assistance from the U.S. Department of Energy and the nonprofit Alliance to Save Energy, here are some tips for being more efficient as the heat waves roll in. (If you have other ideas, please share.
