Frequently Asked Questions — HVAC Installation & Replacement
How much does a new HVAC system cost in Tennessee, Alabama, or Kentucky?
A new central AC system installation in Tennessee, Alabama, and Kentucky typically ranges from $3,500–$8,500 depending on system size (measured in tons), equipment efficiency rating (SEER2), brand, and complexity of the ductwork. Heat pump installations follow similar pricing. Gas furnace installations range from $2,500–$5,500 for equipment and labor. Technicians provide detailed quotes after assessing your home's square footage and duct condition.
What SEER2 rating should I choose for my new AC system?
For Tennessee, Alabama, and Kentucky climates, a minimum of 15 SEER2 is recommended given long cooling seasons. Higher SEER2 units (18–20+) deliver greater energy savings but come at a higher upfront cost. For most homeowners, a 15–17 SEER2 unit offers the best balance of purchase price and long-term operating savings.
Should I replace just the outdoor unit or the whole HVAC system?
HVAC professionals generally recommend replacing the entire matched system (outdoor condenser + indoor air handler or furnace) together. Mismatched systems can reduce efficiency and may void manufacturer warranties. If your indoor unit is more than 10 years old, a full system replacement is usually the most cost-effective long-term decision.
How long does HVAC installation take?
A standard residential HVAC system replacement typically takes 4–8 hours for a single-day installation, assuming existing ductwork is in good condition. More complex jobs involving new ductwork, electrical upgrades, or gas line work may require additional time. Your technician will confirm the expected timeline during the in-home assessment.
