At MCX Air Systems, our Coolant Level Check service uses professional-grade manifold gauge equipment to accurately measure the refrigerant pressure and charge in your system. Unlike a basic visual check, our pressure test tells us exactly how your system is performing and whether the refrigerant level is within the manufacturer's specified range. If a top-up is needed, we use only EPA-approved refrigerants — including R-410A for modern systems — and we never recharge a system without first checking for the underlying cause of the loss.
It's important to understand that refrigerant doesn't simply "run out" — if your system is low, it means there is a leak somewhere that needs to be found and fixed. Our technicians are trained to diagnose both the symptom and the source, so you're not just getting a temporary fix. We provide a complete service that addresses the root cause and restores your system to full operating capacity safely and correctly.
Signs Your System May Be Low on Refrigerant
Low refrigerant affects your system's performance in several noticeable ways. If you're experiencing any of the following, call MCX Air Systems at (562) 200-8712 — catching it early can prevent a much more expensive compressor repair down the line:
- AC blowing warm or barely cool air
- Ice forming on the refrigerant lines or coil
- System running continuously without cooling
- Hissing or bubbling sounds near the unit
- Noticeably higher electricity bills than usual
- Warm air from vents despite thermostat set low
- Longer-than-normal cooling cycles
- System short-cycling or turning off unexpectedly
