Local Factors
When budgeting for your HVAC or AC replacement in Lilburn, keep these local factors in mind:
- Permits: Gwinnett County requires permits for HVAC installations. The cost varies depending on the scope of the work, but typically ranges from $50 to $300. Your contractor should handle the permit process.
- Installation Labor Rates: Labor rates for HVAC technicians in the Lilburn area average $75 to $150 per hour. The total labor cost will depend on the complexity of the installation and the amount of time required. More complex installations, like those involving ductwork modification or running new electrical lines, will increase labor costs.

Weather Impact
Lilburn’s humid subtropical climate significantly impacts HVAC system performance. The hot, humid summers demand systems with excellent moisture control to prevent mold and mildew growth. Consider systems with dehumidification features. Georgia’s high pollen counts, especially in spring, make proper air filtration crucial. Look for systems compatible with HEPA filters and consider adding a UV light air purifier to your system to kill airborne allergens and bacteria.
Upgrading to a system that meets the new SEER2 standards (which went into effect in 2023) is a smart move. SEER2 ratings offer a more accurate measurement of efficiency, reflecting real-world operating conditions. A higher SEER2 rating translates to lower energy bills during Lilburn’s long cooling season. Heat pumps are an excellent option for Lilburn homeowners. They provide efficient cooling in the summer and heating in the milder winters, making them a versatile and cost-effective choice.
