Frequently Asked Questions — Louisville, KY
How much does a new HVAC system cost for a Louisville home?
Most Louisville homes pay $5,500–$12,000 for a complete heat-and-cool replacement, depending on home size, SEER rating, and ductwork condition. Heat pumps run slightly higher upfront but save 20–40% on Louisville winter bills.
When should I replace my Louisville home's AC unit?
If your AC is 12+ years old, uses R-22 refrigerant, or needs repairs over $500, replacement usually beats repair. Louisville's long, humid summers wear systems faster than the national average — most last 12–15 years here.
Do I need a permit for HVAC replacement in Louisville?
Yes. Louisville Metro requires a mechanical permit and inspection for furnace, AC, or heat-pump replacements. Hadley Energy Solutions pulls all permits and schedules the inspection — it's included in our quote, never billed separately.
What HVAC brand is best for Louisville's climate?
We install Carrier, Trane, Lennox, Rheem, Goodman, and Daikin — all perform well in Louisville. Brand matters less than proper sizing (Manual J), good ductwork, and a quality install. We're brand-neutral and recommend based on your home, not commission.
