Window replacement costs in Little Rock

Little Rock gives a window a long, hot season to get through. Adams Field averages about 76 days a year at 90 degrees or hotter, and 7 or 8 of them top 100. Winter is shorter but real: the low reaches freezing or below on about 50 nights a year.

The energy rules are modest. The U.S. Department of Energy's code tracker lists Arkansas's residential energy code as the 2009 International Energy Conservation Code, in effect since January 1, 2015. Pulaski County is in climate zone 3, by the national map's definition a mixed-humid one, so a Little Rock house works the air conditioner through a long summer and the furnace through a real winter.

Much of the housing predates even that code. The metro's median house dates to 1990; more than a third were standing by 1980, and about one in eight by 1960, Census figures show.

On an older house, the west wall takes the late-day sun through all those 90-degree afternoons. That makes it a good place to start when you look your windows over for fogged glass or a sash that sticks.
