Gasket sealing is the process of using flexible, heat-resistant materials like rubber, cork, or silicone to create an airtight and watertight bond between two HVAC components. In Mobile Home Furnaces, high-temperature gaskets are essential for sealing the burner assembly and the heat exchanger to prevent dangerous exhaust leaks. Without a proper gasket seal, your Air Handlers could lose a significant amount of static pressure, leading to poor airflow in distant rooms. We provide specialized replacement gaskets in our Parts collection for various blower housings and access panels. Over time, these seals can become brittle or cracked due to constant thermal expansion and contraction. Applying a new gasket is a cost-effective way to restore the efficiency of your Ducted system and reduce whistling noises. It is a critical component for maintaining the integrity of the "cabinet seal" in all ACIq equipment. Proper sealing is the first line of defense against energy loss.
