Homes & equipment
Heating and cooling in Kentucky
Gas furnaces with central AC are common in cities, while rural homes and eastern Kentucky often rely on heat pumps or propane. Many older homes in Louisville have basements with furnaces and ductwork.
Basement and crawl space moisture can affect air quality, and dehumidification is often worth discussing.
Common problems
HVAC problems we see in Kentucky
River-valley humidity
Humid summers make proper AC sizing and drainage important, especially in basements.
Winter cold snaps
Heat pumps lean on backup heat during deep cold, so backup strips and outdoor thermostats should be checked.
Flooding
Basement furnaces and outdoor units in flood-prone areas need inspection after high water.

FAQ
Kentucky HVAC questions
Is a dual-fuel system worth it in Kentucky?+
Often. A heat pump handles mild days efficiently, and a gas furnace takes over during cold snaps.
