1st Choice HVAC: Licensed HVAC Services Serving Marietta, GA 30066

Short cycling—where your system turns on and off too frequently—is often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat. Here in Marietta's climate, it's a common issue that strains your system and hikes up energy bills. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause, whether it's a simple filter change, recharging refrigerant, or calibrating your thermostat, to restore proper, efficient operation and protect your equipment.

Absolutely. Mold in ductwork is a serious concern for Marietta homeowners due to our humidity, and it can affect your health and your system's performance. We offer professional duct inspections using specialized cameras. If we find contamination, our NADCA-certified duct cleaning service safely removes mold, dust, and allergens. We also check for and seal duct leaks, a common source of moisture intrusion, to help prevent mold from returning and improve your home's overall air quality.

Our top advice is consistent, preventative maintenance. For Marietta's hot summers and variable winters, we recommend a bi-annual professional tune-up—once in spring for your AC and once in fall for your heating. This includes checking refrigerant levels, cleaning coils, inspecting electrical components, and ensuring proper airflow. This proactive care is the most effective way to prevent common local issues like short cycling, catch minor problems before they become major repairs, and keep your system running efficiently all year, saving you money and hassle.
