QStarr Mechanical Heating & Cooling | Licensed HVAC Repair in Marietta, GA

Our humid climate causes condensation to build up quickly in your AC system. This moisture travels through a drain line, which can get clogged with algae and debris, leading to water leaks and potential damage. We clear the blockage using specialized tools and often apply an algae treatment to prevent future clogs, protecting your system and your home.

Signs include a musty odor when the system runs, increased allergy symptoms, or visible mold around vents. Mold thrives in the dark, damp environment of ductwork, especially if there's excess moisture from a clogged drain. We perform a comprehensive duct cleaning and inspection, removing contaminants and identifying the moisture source to prevent recurrence and improve your indoor air quality.

We recommend bi-annual maintenance, especially before summer and winter. Our preventative service includes checking and clearing the condensate drain, inspecting ductwork for moisture and debris, changing filters, and ensuring the entire system is sealed and efficient. This proactive care is the best way to avoid emergencies, improve efficiency, and extend the life of your HVAC system in Marietta's climate.
