In HVAC work, the application and service temperature of your HVAC tape may not be the same, and each can have an impact on the tape’s performance.
Application Temperature is exactly what it sounds like: the temperature at the point that the tape is applied. Application temperature can impact how quickly an HVAC tape bonds with the surface to which it is applied and potentially how strong that bond is, depending on the tape used. For instance, a tape that is applied in a very cold environment should be specifically approved for cold temperature application, whereas a tape being applied at room temperature would form a strong bond even if it is not built specifically for a certain temperature.
Service temperature is the temperature to which your HVAC tape will need to withstand throughout the life cycle of the system after application. The risk for tape failure increases when tapes that are not built to regularly withstand extreme temperatures are used in HVAC systems. If your system will be exposed to temperatures under 32 degrees F or above 100 F, you should consider a tape that is labeled as having a service temperature with a greater range in order to ensure strong performance.
Choosing the right tape for the job is critical for your HVAC system. All tapes are not created equal, so make sure you know the conditions of your job site before you choose a tape so that you can ensure full system closure.
