Louisville chimney service: American Chimney & Fireplace for area code 502

About homes and winters in area code 502

Area code 502 covers Louisville and the surrounding Kentucky counties, from Louisville and Jeffersontown to Shelbyville, Shepherdsville, La Grange and Elizabethtown. It is an old housing stock: of about 537,000 homes and apartments, roughly 55% were built before 1980 and 12% before 1940, and the median home dates from the 1970s. About 69% are single-family detached houses.

Louisville is the most populous city in the U.S. state of Kentucky, sixth-most populous city in the Southeast, and the 27th-most-populous city in the United States. By land area, it is the country's 24th-largest city; however, by population density, it is the 265th most dense city.

Winters bring a real heating season. NOAA's 1991–2020 normals for Louisville International Airport, KY show about 3,936 heating degree days a year, a January average of 35.7°F, and about 13.4 inches of snow. Rain and the occasional freeze still work on brick and mortar over the years, so a cracked crown or a missing cap is worth fixing early.

The most common way to heat a home here is utility gas (about 51% of occupied homes, per the Census), followed by electricity at about 44%. Wood is the main heat in fewer than 2 in 100 homes, so most fireplaces here are for cool evenings, and gas fireplaces and inserts are common. Energy codes place it in IECC climate zone 4A. NFPA 211, the national chimney and venting standard, recommends an inspection every year no matter what you burn.
