## FAQ

### How much does a new AC cost in Nashville?
A new 3-ton AC and air handler installed in a typical Nashville home runs $5,500 to $9,200 in 2026 for a 14.3 SEER2 system, or $8,500 to $12,500 for a 16+ SEER2 variable-speed system.

### How long does HVAC installation take?
A straightforward system replacement is one day. New ductwork or zoning can extend to 2–3 days.

### Heat pump or gas furnace in Nashville?
Modern cold-climate heat pumps work well down to 5°F, which covers nearly all Nashville winters. Heat pumps qualify for a 30% federal tax credit (up to $2,000). Gas furnaces remain cheaper to run during the few sub-20°F nights.

### How often should HVAC be serviced?
Twice a year — spring for AC, fall for heat. Annual tune-ups extend equipment life by 30–50%.

### How do I know if my AC needs replacement?
If your unit is 12+ years old, uses R-22 refrigerant, has had 2+ major repairs, or your energy bill is climbing, replacement usually pays back faster than repair.

### Is duct cleaning worth it?
It's worth it after renovations, after a rodent issue, or if you have moderate-to-severe allergies. For most homes with modern filters and no obvious contamination, the EPA says routine cleaning isn't necessary.
