When should HVAC tape be replaced?

by | Nov 10, 2022 | HVAC Tape

HVAC tape can fail over time, especially when installed incorrectly.

HVAC tape is a vital component of any HVAC system. With the goal of full-system closure being the number-one priority for HVAC installs and maintenance jobs, it’s important to consider the longevity of its component parts.

What many people don’t realize is that HVAC tapes can wear down over time. However, there are a few ways to make sure that your tape will last as long as possible before needing to be replaced.

First steps

Before you buy HVAC tape, you should consider two factors that can impact a tape’s lifespan. First, only use tape that is UL-listed, as it confirms the tape will meet safety standards and inspections. Using tape that isn’t UL-listed can result in a poor seal or failed inspections, jeopardizing your work and reputation.

Second, make sure that the tape you are using is right for the climate. Colder environments will require tape that can withstand colder temperatures, while warmer ones will require tape that can withstand normal environments.

Signs of tape failure

Tape flagging is the surest sign of tape failure. It can be caused by a number of factors: using the wrong tape for the job or not applying it correctly. Another possible reason for flagging could be the tape itself: it could simply just not have been constructed very well.

The best way to prevent tape flagging is simple: pick the right tape for the job and apply it properly. If you see HVAC tape that is flagging, it’s time to replace it.

Tape storage

Another thing to consider is tape has a shelf life. A general rule to follow is to replace unused tape that has aged at least a year or so – although this number can vary depending on storage.

You can get the most life out of your HVAC tape by storing it correctly. To properly store your HVAC tape, simply lay it on its side with the core facing up. Be sure to keep the tape stored away from dirt or other debris that could become attached to the adhesive. It’s also best practice to not stand the tape on its edge, as this can cause it to become distorted.
