Mission: HVAC 2017 – Challenge 5: What’s Trending?

Last month, we learned about the trend of reflective insulation, but for this challenge, we asked our Mission: HVAC students to consider some of the other trends in the HVAC industry for the regions where they live. Differences in temperature and climate conditions vary across the country, and with them come different challenges for HVAC technicians. Let’s find out what Aaron, Gustavo, and Chris have to say about industry trends in their hometowns: Last month, we learned about the trend of reflective insulation, but for this challenge, we asked our Mission: HVAC students to consider some of the other trends...

Why can’t I use general purpose duct tape on HVAC ductwork?

Duct tape is useful for repairing just about anything, but ironically, not for ducts. Although the name might be misleading, general purpose duct tape was not designed for use in HVAC ductwork at all. In fact, if you tried using “regular” duct tape on your ductwork, it would more than likely fail. The adhesive used in general purpose duct tape is not built to withstand the conditions that HVAC-specific tapes are tested to perform in. Cold and hot temperatures can cause this type of duct tape to flag and fall off, leaving leaks in the system that can result...

What’s the value of a UV-resistant stucco tape?

Many stucco tapes are constructed to with a UV-resistant backing because they are for use on exterior surfaces, often in hot, sunny climates. Sunlight contains harsh UV rays which can cause negative changes to the physical properties of many tapes. Certain components of tapes, such as rubber adhesives and polyethylene (PE) backing can become hard and brittle as a result of prolonged exposure to UV rays. If the tape is unable to retain the physical properties that allow it to bond to stucco windows, door frames, and other surfaces involved in stucco work, it is at a high risk...

Why are some HVAC tapes printable?

Printability is an important consideration to HVAC tape manufacturers because it allows information to be printed on the tape itself in addition to being on the core of the roll and on the packaging. In HVAC system inspections, inspectors need to be able to quickly determine if the materials used to seal the system meet the proper codes and standards that are required, and printed tapes make quick work of it. For example, most UL listed tapes will have the UL code and manufacturer’s file number printed on the backing to let inspectors know that it meets UL performance...

Mission: HVAC 2017 – Challenge 4: Reflective Insulation

One of the current trends in HVAC is reflective insulation, a material that is used to wrap ductwork in order to provide an additional barrier against unconditioned spaces and keep the air being heated or cooled by the HVAC system at the proper temperature without seeping out of the duct, thus increasing the efficiency of the system overall. In order to understand how this trend is shaping the industry, we asked our Mission: HVAC students to share about their experiences working with reflective insulation. Here’s what they shared: Aaron: A Growing Trend For mission four I had the chance...
