  • Question: How do you know if your HVAC system needs a leak sealant?

    Answer: Signs that your HVAC system may need a leak sealant include inconsistent cooling or heating, increased energy bills, and hissing or bubbling sounds coming from the unit. If you experience any of these symptoms, it may indicate refrigerant loss due to a leak. Using TSI Supercool 28399 can help you address these issues quickly. Performing regular checks on your system can help prevent further damage and ensure that your HVAC operates efficiently, providing reliable indoor comfort.
  • Question: Can I use TSI Supercool 28399 in conjunction with other products?

    Answer: Yes, TSI Supercool 28399 can often be used with other HVAC maintenance products, such as refrigerant or oil additives. However, it’s essential to read the manufacturer's instructions on each product to ensure compatibility.

For instance, applying a refrigerant and then sealing potential leaks with TSI Supercool can significantly improve system reliability.

    Answer: For an average-sized HVAC system, a single application of TSI Supercool 28399 (2 fl. oz. or 60 mL) is typically sufficient. This product is formulated to address small leaks effectively; thus, using too much may not yield better results. It's advisable to evaluate the severity of the leaks first. If you're unsure, applying the product methodically and monitoring the system’s performance afterward can guide your next steps. Always follow the guidelines for application to ensure the best outcomes.
  • Question: How long does it take for the sealant to take effect?

    Answer: The TSI Supercool 28399 sealant begins to address leaks almost immediately upon application. However, it may take a few hours for the full effects to stabilize and provide optimal sealing. This quick action is beneficial in emergency leak situations, allowing for rapid rectification. After using, monitor your HVAC system for any residual issues and ensure that it is performing adequately. Regular checks will help confirm that the leak has been effectively sealed.
