Low refrigerant is a symptom, not a solution. We use ultrasonic and electronic "sniffers" to find the leak, fix the line, and protect your system from terminal failure.
Many technicians simply "top off" a system with refrigerant and leave. At Working Class HVAC, we consider that malpractice. A leak in your AC coils or copper lines allows moisture and non-condensables to enter your system, leading to acid buildup and compressor burnout. We use nitrogen pressure testing and electronic sniffer technology to locate microscopic leaks in evaporator coils and flare fittings, ensuring your repair is permanent.
