Spectroline Leak Detection’s North America Sales Manager, Matthew Cowley, speaks on the HVAC Know It All Podcast with host Gary McCreadie to discuss common myths and outdated beliefs about HVAC sealants and more! Watch both part 1 et part 2 now.
Part 1 Recap
They chat about the truth behind internal sealants used in HVAC systems. They explain how older polymer-based sealants caused problems due to chemical reactions, while new oil-based ones work safely with mechanical action. Matt and Gary talk about how oil-based sealants coat leak areas from the inside without clogging or damaging parts. They also share stories from real HVAC jobs, testing tips, and why more people are starting to trust this modern sealant method. Matt explains how modern oil-based sealants are safer for HVAC systems than old polymer ones. He shares how these sealants coat tiny leaks from inside without hardening or clogging parts. Matthew talks about how they need pressure, heat, and small leak spots to work well. He also explains why these sealants don’t hide damage but help prevent bigger leaks. Gary adds real job stories showing how these sealants fixed small leaks without harming systems. They both agree that with testing and care, this method can save time, money, and prevent future service calls. Here, Matthew explains how oil-based sealants work safely by coating leaks from the inside without reacting to air. Like using oil between gears, it seals without blocking flow. He talks about how these sealants need heat, pressure, and tiny leak spots to work well. Matthew warns that they won’t fix big leaks, but are great for small, hard-to-find ones. Gary adds that testing over time shows no damage to systems. They remind techs that using sealant with care can help avoid repeat leaks and keep systems running quietly and smoothly.
Expect to Learn:
PART 1 –
1. Why old polymer sealants cause damage in HVAC systems.
2. How oil-based sealants work without hardening or clogging.
3. Why are these sealants best for tiny, hard-to-find leaks?
4. How real job testing shows they don’t harm compressors.
5. Why careful use can help stop leaks and avoid callbacks.
Part 2 Recap
They discuss the leak sealants, their proper use, and common misconceptions. Matt explains how Spectronics’ oil-based, solvent-free sealant is safe and effective for tiny evaporator leaks. Gary shares tips from his article on diagnosing and fixing leaks, stressing that sealants should only be used when repairs aren’t possible. They also talk about the EZ-Ject injection method, which makes applying sealant clean and simple. The episode ends with a push for better research and open-mindedness in the HVAC trade. Matthew explains how Spectronics Corporation’s sealants work to fix very small refrigerant leaks, especially in hard-to-reach places like evaporator coils. He talks about the importance of finding and confirming a leak before using a sealant. Matthew also shares how their dye and sealant mix is safe, oil-based, and doesn’t harm HVAC systems. Gary adds tips from his own testing and stresses that sealants should be used only when proper repairs aren’t possible. They finish by urging techs to learn, test products, and stay open-minded about modern leak solutions. Throughout this episode, Matthew talks about the safe use of leak sealants in HVAC systems. He explains that their oil-based formula works well for small leaks and doesn’t harm system parts. He and Gary stress the need to confirm a leak before using sealant and only apply it when a repair isn’t possible. Matthew also explains their clean and EZ-Ject injection tool. Lastly, they talk about learning, testing products, and staying open-minded to new tools and methods in the HVAC field.
Expect to Learn:
