This is a common issue we see. It can be due to Wi-Fi interference, incorrect wiring during installation, a firmware glitch, or a compatibility problem with your specific furnace or AC unit.

Yes, a loss of cooling power is often a sign of a refrigerant leak, which is not only inefficient but can damage your compressor. We first perform a thorough leak detection test to locate the source. We then repair the leak, evacuate the system to remove moisture and air, and recharge it with the precise amount of refrigerant specified by the manufacturer, restoring efficiency and cooling performance.

If you notice weak airflow, ice on the coils, or hissing sounds, turn the system off to prevent further compressor damage and contact us right away. Continuing to run a system with a leak can lead to a complete breakdown. Our emergency service team can quickly diagnose the issue, contain the leak, and perform the necessary repair to protect your investment and your comfort.
