Frequently Asked Questions

A sight glass is a transparent component installed in HVAC systems to allow visual monitoring of refrigerant flow and condition. It helps technicians assess system performance and detect moisture or contaminants in the refrigerant.

A moisture indicator monitors the presence of moisture in the refrigerant. Moisture in the system can cause damage to components like compressors, and the indicator helps identify when the system needs maintenance or refrigerant changes.

The choice of sight glass or moisture indicator depends on the type of refrigerant used and the system’s pressure and temperature specifications. Our customer service team can assist you in selecting the appropriate model based on your system's needs.

Installation is generally straightforward, but it is recommended to follow manufacturer guidelines or consult with a professional technician to ensure proper installation and system compatibility.

Regular maintenance involves checking the sight glass for cracks or damage and ensuring the moisture indicator is functioning correctly. If moisture is present in the system, or if the sight glass is broken, it should be replaced immediately to maintain system integrity.
