Local Factors
Several local factors impact the cost of HVAC and AC replacement in Dunwoody:
- Permits: DeKalb County requires permits for HVAC system replacements. The cost varies, but budget around $100-$300 for permitting fees. Your contractor should handle the permit process.
- Installation Labor Rates: Labor rates for HVAC technicians in the Dunwoody area typically range from $75 to $150 per hour. The complexity of the installation (e.g., ductwork modifications, accessibility) will affect the total labor cost.
- Contractor Licensing: Always ensure your HVAC contractor is licensed by the Georgia State Construction Industry Licensing Board. This protects you from unqualified or fraudulent contractors.
- Home Age: Older homes in Dunwoody may require additional work to bring ductwork up to code or address insulation issues, which can increase the overall cost.
Weather Impact
Dunwoody’s humid subtropical climate significantly impacts HVAC system selection and efficiency. Here’s how:
- Humidity Control: The high humidity levels during Georgia summers make it crucial to choose a system with excellent dehumidification capabilities. Look for features like variable-speed blowers, which can remove more moisture from the air. Poor humidity control can lead to mold growth and discomfort.
- Pollen Filtration: Georgia experiences very high pollen counts, especially in the spring. Consider systems with advanced air filtration, such as HEPA filters and UV light air purifiers, to improve indoor air quality and reduce allergy symptoms. MERV 13 filters or higher are generally recommended.
- SEER2 Ratings: Georgia Power customers can benefit from upgrading to higher SEER2 rated systems. The new SEER2 standards mean the testing is more rigorous and reflects real-world conditions. A higher SEER2 rating translates to lower energy consumption and reduced cooling bills during Dunwoody’s long, hot summers.
- Heat Pumps: Dunwoody’s relatively mild winters make heat pumps an efficient and cost-effective option for year-round comfort. Modern heat pumps are highly efficient in both heating and cooling modes.
