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.

Fire and Ice has been wonderful to work with! Our new Furnace and AC are working like a dream. We had a number of places come out for estimates and Fire and Ice was the only one who actually went around and measured our windows and home and determined we should get a smaller furnace than what was installed before, saving us money both up front and on efficiency down the road. We were also impressed at the quality of the installation itself, as our old setup was clearly done without much care or thought. Fire and Ice took the time to move pipes and such that were just hanging from my ceiling before, move the humidifier to the proper side of the furnace, move over the ductwork that was not put in a good location, raise our electrical box outside away from the ground, and all kinds of little things to make sure our system runs right for a long time. It's been a few months and our setup runs perfectly. You get what you pay for, and I'm glad we paid for Fire and Ice!

When the 30 year old HVAC system in our house went out Fire and Ice was recommended to me. Brad, my sales representative, showed me a comprehensive list of my options, set me up with financing make a brand new system affordable, and professionally communicated throughout the entire process. The installers, Demetrius, Willard, and Tyler, were fantastic! They were very helpful and professional throughout the entire installation process and walked us through the ins and outs of the final product. The AC works like a dream just in time for the hot summer weather and we could not be happier! Fire and Ice is our go-to recommendation for anyone seeking HVAC work.

Our complete HVAC system was replaced a month ago. We experienced a flawless, informative process from sales to installation. Bryan, our sales pro, performed a detailed anaysis of our home's size, construction & features to develop an evaluation of our HVAC needs to offer the optimum sized equipment and has returned several times since the installation to insure it's proper functioning and our understanding of the entire system. The installation was performed within 3 days of our agreement - with the crew (Jon, Daniqua & Colby) getting the old system removed (furnace & A/C) and the new system installed in a matter of hours - they even modified ductwork and rerouted some lines originally installed by our builder to increase efficiency and give the system a cleaner appearance. Another great surprise was their tenacity with the cleanup - all their work areas were left totally spotless!!! Overall the best contractor performance we have experienced in 35 years of home ownership including having 2 homes built by the area's most reputable developers. The system runs great, is quiet and can now be operated through my phone from anywhere - even if just to insure it's running while at my winter haven. Thank You Fire & Ice!

Fire & Ice was great. Our sales rep, Bryan, was excellent. He was knowledgeable, professional, and didn’t pressure us to make a purchase. Due to our experience with him, we were already planning on using Fire & Ice to replace our old AC, but during the heat wave and storms, my once limping-along-AC decided 20 years was enough cooling and decided it’s job was done. My husband had initially set the meeting with Bryan, but was out of town, leaving me to pick up the sale. Bryan didn’t miss a beat when I emailed him asking to get a new AC installed ASAP. Within two days, my install techs, Demetrius P. and Willard J. were here to install. The excellent service continued. Both were amazing and incredibly professional, even dealing with my very vocal dog with grace every time they entered my house. They completed the job in a timely manner and everything was top notch. They were mindful of the fact that I work from home, and kept noise to an absolute minimum. By the time they left, I could feel the cool air flowing once again. They even took the time to swap out my furnace filter! Loved working with them and will recommend Fire & Ice to my friends & neighbors.

The entire process of having a new furnace and air conditioner installed was awesome. Scheduling the estimate was quick and easy and I didn't have to wait on availability. The estimate was very thorough, and Bryan was extremely helpful in explaining everything. Install was just a few days later based on my schedule (they could have installed sooner) and the install technicians (Bryan, Alontae, Von) were awesome. Very professional and courteous, adhering to local health guidelines the entire time. They also had somebody come out and take photos and videos of the install so they could use it in their training. They took the time to ensure everything was installed properly (my old install wasn't). They were also very helpful to show me everything about the system and new thermostat before they left. Bryan followed up with me a week later and stopped in to check on the install. He's awesome and having a tech come out and tweak a couple things (humidifier and thermostat) to ensure everything runs properly!

One of my good friend’s had a great experience with Fire and Ice, so I went ahead and tried them out. Amazing customers service. Brad was awesome with walking me through the process of getting a new furnace and answered all of my questions. I will be a returning customer and recommend Fire and Ice to all. Update on furnace installed: I can not praise this company enough. The technicians Floyd and Jacob were very professional and the craftsmanship was amazing. You can tell when someone takes pride in their work. Thank you for your hard work. It’s greatly appreciated.

Bryan and Nick were true professionals. They gave me a good heads up when they were going to arrive and did a great job installing the new furnace. They made sure to keep my house clean and walked me through what they did and gave me tips on how to get the best use/life out of my furnace. Will definitely recommend to a friend.

The two technicians arrived exactly when they said they would, immediately began to take care of business. They had more trouble than they anticipated getting the old furnace out but still pretty much finished at the time they told me. The system and heating space were left clean and tidy. they took a few extra minutes to troubleshoot my water tank to get it to ignite which was greatly appreciated. Very nice gentleman throughout the experience and gave me a thorough explanation of the paperwork and how to use the thermostat as well. Was a great experience
