Local Factors
In Cobb County, including Marietta, you’ll likely need a permit for HVAC replacement. Contact the Cobb County Building Inspections Department to verify specific requirements and fees. Installation labor rates typically range from $75 to $150 per hour, depending on the contractor’s experience and the complexity of the job. Remember to always verify that your chosen contractor is licensed by the Georgia State Construction Industry Licensing Board. Unlicensed contractors may not adhere to safety and building codes, potentially leading to future problems and invalidating warranties.
Weather Impact
Marietta’s humid subtropical climate significantly impacts your HVAC choices. The hot, humid summers necessitate systems with excellent moisture control to prevent mold and mildew growth indoors. Consider units with dehumidification features. Furthermore, Georgia’s high pollen counts in spring mean that high-quality air filtration is essential. Look for systems compatible with HEPA filters and consider adding a UV light air purifier to kill airborne allergens and bacteria. Upgrading to a higher SEER2 rated system not only improves energy efficiency but also reduces strain on your system during peak cooling season, lowering your Georgia Power bills. Heat pumps are also an excellent choice, offering efficient heating during our mild winters and powerful cooling during the hot summers.
