Refrigerant Leaks Destroy Cooling
If your AC isn't cooling like it should, low refrigerant is often the culprit. Refrigerant circulates through your system to absorb heat and cool your home—without proper levels, your AC fails to deliver. J. Marin Heating & Air Conditioning diagnoses refrigerant problems, locates leaks, seals them permanently, and recharges your system to manufacturer specification.
Finding and Fixing Leaks
Our technicians use specialized equipment to detect even small refrigerant leaks in your lines, connections, and coils. Once we locate the leak, we repair or replace the damaged component and verify the fix before recharging. We don't guess—we test and confirm your system is sealed and operating at peak performance.
Recharge to Spec
Proper refrigerant charge is critical to efficiency and cooling power. We recharge your system to the exact specification for your AC unit, ensuring optimal heat absorption and cooling performance. This means faster cooling, better comfort, and lower energy bills.
