Frequently Asked Questions About HVAC in Marietta

Get answers to common questions about hvac services in Marietta, Georgia.

1What is the typical cost range for replacing a central HVAC system in a Marietta home?

For a full system replacement (air conditioner and furnace or heat pump) in Marietta, homeowners can typically expect to invest between $6,500 and $12,000+, depending on system size (measured in tons), efficiency rating (SEER2), and home complexity. Georgia's hot, humid summers make a properly sized and efficient system critical for comfort and energy bills. Always get detailed, written estimates from multiple licensed local contractors that include equipment, labor, and any necessary duct modifications.

2When is the best time of year to schedule HVAC maintenance or replacement in Marietta?

The ideal times are during the mild shoulder seasons of early spring (March-April) and early fall (September-October). Scheduling during these periods ensures your system is serviced before the peak summer demand and winter chills, and you'll find greater contractor availability and potentially better pricing. Avoid waiting for the first major heatwave in May or June, as HVAC companies are at their busiest and emergency service premiums apply.

3How do I choose a reliable HVAC contractor in the Marietta area?

Always verify the contractor holds a valid Georgia State Conditioned Air Contractors License. Look for established local companies with strong reviews on platforms like Nextdoor that mention positive experiences with Marietta's specific climate challenges. A trustworthy provider will perform a detailed Manual J load calculation for your home—not just match the old unit's size—and provide a clear, written contract outlining scope, equipment model numbers, and warranty details.

4Why is my HVAC system freezing up, and is this a common issue in Marietta's climate?

This is a frequent issue during our long, humid summers. The most common causes are dirty air filters or evaporator coils restricting airflow, or low refrigerant levels due to a leak. When humid Marietta air passes over the too-cold coil, condensation freezes. Homeowners should first check and replace the air filter. If the issue persists, shut the system off and call a professional, as running it can cause severe damage to the compressor.
