Frequently Asked Questions in Georgia
What is the average cost of an HVAC replacement in Georgia?
In Georgia, replacing a full split HVAC system (AC + furnace/heat pump) typically costs between $7,000 and $14,000 depending on tonnage, SEER2 rating, and ductwork modifications.
Is a permit required for HVAC replacement in Georgia?
Yes, Georgia building codes require a mechanical permit and post-installation inspection for full HVAC system replacements.
What HVAC installer licence is required in Georgia?
Work must be completed by a state-licensed HVAC / Conditioned Air Contractor with EPA Section 608 refrigerant certification.
What SEER2 rating is required in Georgia?
Under federal standards implemented in 2023, Southern and mid-Atlantic states require a minimum 14.3 SEER2 for residential split AC systems.
Are energy efficiency rebates available in Georgia?
Yes, Georgia homeowners can claim up to $2,000 in federal Inflation Reduction Act (Section 25C) tax credits for qualifying heat pumps, plus local electric utility rebates.
How long does an HVAC replacement take in Georgia?
A standard like-for-like system swap takes 1 to 2 days. If ductwork needs replacing or sizing, expect 3 to 4 days.
What contract deposit limit applies in Georgia?
No statutory cap (10%–33% deposit customary)
How long does an HVAC system last in Georgia?
In Georgia, HVAC systems typically last 12 to 18 years. Coastal salt air or heavy summer runtime can shorten condenser lifespan.
Is a Manual J load calculation required in Georgia?
Most Georgia jurisdictions mandate a Manual J load calculation to ensure the replacement equipment is properly sized rather than rule-of-thumb estimated.
Where can I verify an HVAC contractor in Georgia?
Verify your contractor's active licence and insurance on the official Georgia licensing portal before signing.
Should I get lien waivers during HVAC System Replacement in Georgia?
Yes. Georgia mechanics lien rules (Preliminary Notice of Lien Rights within 30 days; claim filed within 90 days) make conditional and unconditional waiver forms at each payment draw the best protection for homeowners.
Where do I file a contractor complaint in Georgia?
Start with the state licensing board lookup for trade issues, then the state consumer protection or attorney general office for contract fraud. Permit disputes go to the local building official that issued the permit.
National Baseline & Scope Drivers
Replacing a residential furnace, air conditioner or heat pump, including installation and startup. National planning range for this job sits between $4,500 and $20,000.
Key Price Drivers for HVAC System Replacement
- What you are replacing: A furnace alone, a condenser alone, or a full system with coil and air handler are three very different prices. Matched full-system replacement costs more but performs to its rating.
- Capacity and efficiency: Each additional ton adds cost, and high-SEER2 variable-capacity equipment can double the equipment line versus a base single-stage unit.
- Ductwork condition: Undersized or leaking ductwork must be corrected for the new system to perform. Duct modification frequently adds $1,500 to $5,000 and is the most commonly omitted item in a low bid.
- Electrical and gas work: Heat pump conversions often require a new circuit, a disconnect, and sometimes a panel upgrade. High-efficiency furnaces require new PVC venting and a condensate drain.
- Refrigerant transition: Equipment has moved to A2L refrigerants such as R-454B. Line set compatibility and flush requirements can add cost on a changeout.
