Lexington-Fayette, one city and one county

Lexington Neighborhoods We Serve

Lexington and Fayette County share one government, so a house in Masterson Station and a house off Chevy Chase deal with the same permit office, the same building code and the same utilities. What differs across the areas we serve is the house itself, and that shapes what goes wrong with its heating and cooling.

The Areas We Serve at a Glance

This site focuses on the residential ZIP codes of Lexington-Fayette. We don’t build pages for surrounding towns. Staying inside one city lets us write about the specific housing, weather and permit rules people here deal with, rather than general advice. With about 329,751 residents in the Census Bureau’s July 2025 estimate and roughly 139,700 households, Lexington is large enough that its neighborhoods differ quite a bit from one another.

Older Central Neighborhoods

Chevy Chase and Ashland Park (40502), Kenwick, and the streets of South Hill near downtown hold much of the city’s pre-war housing: brick and frame homes, plaster walls, tall ceilings and basements that were dug for coal furnaces. Central air arrived later, if at all.

What comes up most here:

• Upstairs rooms that run much hotter than the first floor, because ducts were added to attics that were never meant to hold them.
• Gas furnaces in basements venting through old masonry chimneys, sometimes alongside a water heater.
• Homes without any ductwork, where adding central air means planning duct routes carefully to avoid damaging original plaster.
• Historic overlay rules that can affect where an outdoor unit goes on a street-facing side.

Established Suburbs

Tates Creek, Lansdowne, Gardenside and Cardinal Valley grew up mostly from the 1950s through the 1980s. Brick ranches and split-levels are common, many built on crawl spaces or partial basements.

By now, most of those houses are on their second or third HVAC system, and the ductwork is often original. That combination explains a lot of local complaints: a new system that never seems as good as promised because it’s pushing air through 50-year-old metal ducts with open seams in a damp crawl space. Before replacing equipment in these homes, an airflow and duct check is time well spent. The furnace replacement and AC replacement pages go into what that check involves.

Newer Growth Areas

On the east and southeast side, Hamburg (40509), Andover and Hartland (40515) filled in mostly from the 1990s through the 2000s. To the southwest, Beaumont and Palomar (40513) followed a similar timeline, and Masterson Station (40511) grew on the northwest edge.

Two-story homes with attic or closet air handlers are typical. Much of that original equipment is now 15 to 20 years old, and some still runs on R-22 refrigerant. This is where you’ll find the most repair-or-replace decisions right now, along with upstairs bedrooms that overheat when an attic air handler bakes in July. If the system is still worth fixing, start with AC repair or furnace repair. If it isn’t, AC replacement covers how to weigh the decision.

East Side Estates

Greenbrier and the larger lots nearby include bigger custom homes, often with two or three separate systems, one per floor or wing. Zoning, finished basements and long duct runs make balancing harder. Keeping each furnace and air conditioner on a regular cleaning schedule matters more when one failure leaves an entire floor without heat or cooling.
