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...
