Cashiers sits on a high plateau at nearly 3,500 feet with cold, wet winters and cool summers. The area's heavy concentration of luxury second homes and vacation properties means HVAC systems often serve intermittently — creating freeze risks when homes sit empty and demanding instant performance when owners arrive. The region's 80+ inches of annual rainfall rivals Brevard for moisture challenges, making whole-home dehumidification essential even in summer.

First: "Freon" Is an Outdated Term (But We Know What You Mean)

Freon is a brand name for R-22 refrigerant, which was phased out in 2020 due to its ozone-depleting properties. Most modern systems use R-410A (Puron), and newer systems are transitioning to R-454B. Regardless of the type, the signs of low refrigerant are the same, and only a licensed HVAC technician with EPA 608 certification can legally handle, test, or recharge refrigerant in any system.

Signs Your AC Is Low on Refrigerant

The most reliable indicators are: (1) Warm air from vents despite the system running normally — the AC can't absorb enough heat with reduced refrigerant. (2) Ice forming on the refrigerant lines or evaporator coil — low refrigerant causes excessive pressure drop and freezing. (3) Higher than normal electricity bills — the system runs longer trying to cool with reduced capacity. (4) A hissing or bubbling sound near the indoor unit — this can indicate a refrigerant leak in the evaporator coil. (5) The system runs constantly without reaching the set temperature.

Why Adding Refrigerant Isn't the Real Fix

Refrigerant doesn't get "used up" like gasoline. If your system is low, it's because there's a leak somewhere in the sealed refrigerant circuit. Simply topping off the refrigerant without finding and repairing the leak means the refrigerant will slowly escape again, and you'll be back to the same problem in weeks or months. A proper repair involves leak detection, repair, system evacuation, and recharging to the manufacturer's specification.

Quality Comfort's technicians use electronic leak detectors, UV dye, and nitrogen pressure testing to locate refrigerant leaks accurately. Leak locations vary — evaporator coils, condenser coils, line sets, and flare connections are common spots. Repair costs depend on the leak location and accessibility. If your system uses R-22 and has a major leak, converting to a modern R-410A system through AC replacement may be more cost-effective than repeated R-22 charges, which now cost $100–$200 per pound.
