Mission: HVAC 2017 – Mission 10: Mission Completion

Mission: HVAC 2017 has come to a close – and our students have a few parting words to share about their experiences in the program and the knowledge they gleamed from the past nine missions. They also offered their suggestions for the future of the program – stay tuned and you may see their ideas put into practice in the 2018 program! Congratulations to Aaron, Chris, and Gustavo for completing Mission: HVAC 2017!   For their final mission, each student responded to the following questions: Q1: Which Mission was the most beneficial to you? Q2: What were some of...

What are the benefits of reflective insulation for HVAC ductwork?

The popularity of reflective insulation is growing, and when you understand the benefits that it can have, it’s no wonder. Reflective insulation provides a barrier that reflects radiant heat given off by HVAC ducts back onto itself, allowing it to maintain its temperature and therefore the temperature of the air inside the system. This increases the efficiency of the system by allowing it to keep indoor spaces at the desired temperature for longer without using more energy. A major benefit of reflective insulation is cost savings resulting from improved energy efficiency. Since the HVAC system is able to heat...

Why are air gaps necessary for reflective insulation on HVAC ductwork?

A common question that HVAC technicians who are new to reflective insulation ask is why it must be installed with air gaps at regular intervals between the reflective material and the surface to which it is being applied, such as the outside of a metal duct. To understand why air gaps are critical to the effectiveness of reflective insulation, we need to look at the science behind the way that heat transfers into unconditioned spaces. Radiant heat is a form of heat which transfers between matter across a void or air space through electromagnetic waves rather than through convection...

Mission: HVAC 2017 – Mission 9: Behind the Scenes

For their second-to-last mission, we challenged Aaron, Gustavo, and Chris to tune into the business side of HVAC and do some research on the critical but seldom seen operations that go into running and HVAC business. Through interviews with business owners and pulling from their own experiences in the field, our students shared insiders’ knowledge of the industry.   Aaron: It’s all Part of the Trade Ron Schneider is a local heating and cooling guy that operates his own business. He has been working in the HVAC industry since high school where he started working with his uncle. His...

How do I remove stucco tape?

Stucco tape can be removed in much the same way as a painter’s tape after painting a room. To remove tape that was used to mask off a window, start by gently pulling up a corner of the tape and gradually pulling the tape – and your poly sheeting if you used it – so that it comes off straight and does not shred. If you are removing a straight line of tape, start at the top and pull the tape backwards at a 45 degree angle and slowly pull it off. If any stucco composite is stuck to...
