Infinity Heating & Cooling | Top-Rated HVAC Repair in Lithonia, GA

Common signs in Lithonia homes include weak airflow from vents, strange grinding or squealing noises from the indoor unit, or the system frequently tripping the circuit breaker. If you notice these, it's important to call a professional promptly. A failing fan can lead to overheating and damage other components. Our technicians can diagnose the issue—whether it's a worn motor, a faulty capacitor, or a belt problem—and perform the necessary repair to restore proper airflow and system safety.

We generally recommend checking your air filter every month and replacing it at least every 90 days. However, if you have pets, allergies, or significant dust in the area, changing it every 30-60 days is better. A clogged filter is a leading cause of HVAC issues here, as it restricts airflow, forcing your system to work harder. This can lead to frozen coils, reduced efficiency, and even premature system failure. Regular filter changes are the simplest way to protect your investment and maintain good air quality.

Absolutely. Our comprehensive maintenance service is designed specifically to catch and prevent the problems Lithonia homeowners face. During a tune-up, we thoroughly clean system components, check electrical connections, lubricate moving parts (like fan motors), inspect filters and coils, and test system performance. This proactive care helps identify small issues—like a weakening fan motor or excessive dirt buildup—before they turn into major breakdowns, saving you money and ensuring reliable comfort through our Georgia seasons.
