Frequently Asked Questions
How long does AC installation take?
A standard replacement installation, where the new system replaces existing equipment using existing ductwork, typically takes 1 to 2 days. New installations that require ductwork or electrical upgrades may take 2 to 4 days. We will provide a specific timeline during your consultation.
What size AC do I need for my home?
Proper AC sizing requires a Manual J load calculation that considers your home square footage, insulation, window area and orientation, ceiling height, number of occupants, and Nashville climate data. A 2,000 square foot home in Nashville typically needs a 3 to 4 ton system, but the exact size must be calculated. We perform this calculation as part of every installation consultation.
How much does AC installation cost in Nashville?
AC installation costs in Nashville typically range from $4,500 to $12,000 depending on the system type, size, efficiency level, and installation complexity. A basic single-stage system is at the lower end, while a high-efficiency variable-speed system with advanced controls is at the upper end. We provide detailed quotes with all costs included.
What SEER2 rating should I choose?
The minimum allowed SEER2 rating for new installations in Nashville is 14.3 (equivalent to the old 15 SEER). Systems are available up to 24+ SEER2. Higher efficiency costs more upfront but saves money on energy bills over time. For most Nashville homeowners, a system in the 16 to 18 SEER2 range offers the best balance of efficiency and value.
Do you offer financing for AC installation?
Yes, we offer flexible financing options to make AC installation affordable. Options include 0% interest for qualifying terms, low monthly payment plans, and various term lengths. We work with multiple lenders to find the best option for your situation. Visit our financing page or ask during your consultation for details.
