Hi. I'm Josh with Fire & Ice Heating and Air Conditioning. And today we're going to talk about brazing with nitrogen.

Nitrogen based brazing or brazing with nitrogen is simply purging nitrogen through the copper while you're brazing it. That's it. It keeps it clean. Refrigeration systems need to be very clean and dry before refrigerant is added into it. This will ensure the longevity of the equipment, the efficiency that you deserve, and the comfort that you deserve.

When contaminants go inside of this refrigerant, it will damage this system. It will take place over time. Most likely, it's not going to be something that you experience immediately. So, brazing with nitrogen is the only way to prevent any damage inside the system. So, looking inside this piece, you can obviously tell that there's going to be some contaminants inside of there. As the cutaway shows here, the cutaway of the one that was braised with nitrogen is perfectly clean. In fact, it's cleaner than the copper than when it came.

So, we want to make sure that we're always doing it right. And that's brazing with nitrogen. We know this is important and this is something that we do on every install, every day at fire and ice. So, if you're in need of service or a new install of an air conditioner heat pump, give us a call. Check out our website. We'd love to hear from you here at Fire & Ice.
