How does the 2026 federal refrigerant transition affect my Sandy Springs home's AC repair?

As of January 1, 2026, new environmental regulations have fully shifted the industry toward low-GWP refrigerants like R-454B and R-32. If your current system uses the older R-410A, repair costs for leaks are rising due to diminishing supply. Upgrading to a high-efficiency SEER2 system may be more cost-effective for older units.

Why is my smart-home HVAC system blowing warm air even though my app says it’s cooling?

This is often a communication failure between your smart thermostat and the control board, or a failed mechanical component like a run capacitor or contactor relay in the outdoor condenser. Even if the app shows activity, the compressor won't kick on if these electrical components fail.

Can localized humidity in Sandy Springs actually cause my AC to freeze up?

Yes. Proximity to the Chattahoochee River creates high humidity that forces coils to work overtime. If airflow is restricted by a dirty filter or debris, moisture on the coils can flash-freeze into ice, insulating the coil and causing the system to blow warm air.
