HVAC Repair Marietta GA | Call A & G Heating & Air Conditioning Services

For most homes in Marietta, we recommend having your air ducts professionally cleaned every 3 to 5 years. Factors like local pollen, household pets, recent renovations, or residents with allergies can make more frequent cleaning beneficial. Our thorough cleaning service helps improve your HVAC system's efficiency and your home's overall air quality by removing accumulated dust, allergens, and debris from the ductwork.

Common signs it may be time for a replacement include your system being over 10-15 years old, frequent and costly repairs, uneven heating or cooling, a significant increase in your energy bills, or the system struggling to maintain comfort on very hot or cold days. Since 1983, we've helped Marietta homeowners evaluate their systems. Our technicians can provide a straightforward assessment and explain if a new, more efficient installation would be a more reliable and cost-effective long-term solution for your home.

Yes, a refrigerant leak is a common issue we see in Marietta that causes poor cooling. Signs include warm air from vents, ice on refrigerant lines, and hissing sounds. Our trained technicians first perform a precise leak detection test to locate the source. We then repair the leak according to manufacturer specifications, evacuate the system, and recharge it with the correct amount of refrigerant. Properly fixing the leak, rather than just adding more refrigerant, is crucial for restoring efficiency, preventing further damage, and protecting your investment in the system.
