Louisville homes and their HVAC systems
The Highlands, Germantown and Clifton have many older homes with basements and boilers or retrofitted ducts; St. Matthews and Okolona are mostly post-war with forced air.
Local conditions that affect your system
Humidity
River-valley humidity makes oversized AC and leaky ducts more noticeable.
Freeze-thaw winters
Repeated cycles and cold snaps strain heat pumps and outdoor condensate lines.
Older homes
Adding central air to older homes often needs duct redesign or ductless systems.
Seasons and peak demand in Louisville
Louisville sees hot, sticky summers with highs near 90°F and frequent thunderstorms, and winters that hover around freezing with occasional snow and ice. That mix keeps both AC and heating running for long stretches. Ice storms can bring down power for days, which is hard on heat pumps that rely on electric backup.
