Brazing with Nitrogen for HVAC Installation

Nitrogen based brazing is a technique used during installation that prevents contaminants from entering your HVAC system. In this video, our installation manager demonstrates using nitrogen during the brazing process and explains why we use nitrogen on every installation.

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.

The team from Fire & Ice replaced our heating and air conditioning system in our nearly impossibly small furnace room (I feared they would have to remove our hot water tank and move the washer & dryer to get access to the furnace unit) and the outside was also a task because it required a crane to get the A/C unit on the roof of our condo. The team of pros from Fire & Ice were able to accomplish all of these unusual tasks and kept me fully informed on what was needed for them to get our units replaced. We highly recommend Fire & Ice.

Fire an Ice installed my furnace two years ago so I decided to use them to install my new a/c. Bryan did a great job reviewing all my options and working to get the financing that worked for me. He was also very patient with me and answered all my questions. Demetrius and Will did an amazing job! Considering all the work they did, they were done in four hours. I’m very pleased and would recommend Fire and Ice to anyone needing HVAC services

The sales experience with Luke was great. The installation team of Demetrius, Tyler and Hassan was fantastic. They were on time, were very thorough and did a great job. They take pride in their work and it shows with the final product. They were very respectful, cleaned up and it was a pleasure having them in our house. I highly recommend all these employees and this company. The company is fortunate to have them.

Brandon was the one who installed our new furnace. He was punctual and very professional. Our new furnace is working great and couldn’t be happier with how it looks. Bryan the sales rep was very informational without being pushy and helped us make the best decision for our house. I recommend anyone who needs a new Hvac unit to call fire and ice.

We had 2 AC systems relocated and replaced. Roger (our sales contact), spent most of the day with us calculating the load and measuring the house to ensure proper equipment sizing. Roger was very responsive in helping select a proper and sound location to install the new systems. He came out 3 times to answer questions and inspect the retaining wall/pad. On the day of install, Bryan, Nick and Luke were on time and very respectful of the home. They worked tirelessly the entire day (8am - 6pm) removing the old evaporator(s) and installing the new compressors. Everything was done neatly both inside and out. I would highly recommend their service to anyone considering a new system(s). We just followed up with a pair of new furnaces. Fast scheduling and efficient installation. Luke and Brandon protected the floor and cleaned up after the install.

I had a positive experience with Fire and Ice in the past and my AC installation was even better. Brandon and DQ were very professional. Not only was the install super clean with an impressive 4 fitting duct bend sealed tight, but I needed to work from home during the install and I barely heard them throughout the day. I’ll be recommending F&I to all my friends.
