- Permits: Cobb County requires permits for HVAC system replacements. Your contractor should handle the permit process, and the cost (typically $50 – $300) is usually included in their quote.
- Installation Labor Rates: Labor rates in Kennesaw and the surrounding metro Atlanta area generally range from $75 to $150 per hour, depending on the contractor’s experience and the complexity of the job.

Weather Impact
Kennesaw’s humid subtropical climate significantly impacts HVAC system choices. The hot, humid summers necessitate systems with excellent moisture control. Without it, you risk mold growth and uncomfortable indoor conditions. Look for systems designed to dehumidify efficiently. The area’s high pollen counts, especially in spring, make advanced air filtration crucial. Consider HEPA filters or UV light air purifiers integrated with your HVAC system to improve indoor air quality. Heat pumps are a popular and efficient choice here because they provide effective heating during our mild winters and cooling in the summer. Upgrading to meet the 2026 SEER2 standards will also significantly reduce your energy consumption and save money on your Georgia Power bill, especially during peak cooling months.

FAQ
- How long does HVAC replacement take? Typically, a standard HVAC replacement takes 1-3 days. More complex jobs involving ductwork modifications may take longer.
- Do I need to replace my ductwork when I replace my HVAC system? Not always, but it’s a good idea to have it inspected. Damaged or poorly insulated ductwork can significantly reduce your system’s efficiency. If your ductwork is old, leaky, or improperly sized for the new system, replacement is recommended.
- How do I choose the right size HVAC system for my home? A qualified HVAC contractor will perform a “Manual J” load calculation to determine the correct BTU (British Thermal Units) output for your home based on factors like square footage, insulation, window efficiency, and climate. Oversized or undersized systems will be inefficient and can lead to comfort problems.
