![]() Still, it doesn’t suggest for how long the tape can withstand exposure to extreme conditions. It is also worth noting that the tape’s temperature rating only indicates that its adhesive won’t harden at low or high temperatures. Most HVAC tapes you’ll find on the market have a temperature rating between -25F and 260F, while a handful of models comes with a temperature rating that spans from -40F to 300F. That’s why the tape utilized to fix the leakage needs to maintain its adhesive power at high and low temperatures. Temperature ratingĬonventional HVAC systems endure harsh temperature changes, as the temperature in ducting can rise well above 200F or drop below 10F, depending on the purpose for which you’re using the system. In addition, HVAC tapes can have a backing made of aluminum, foil, aluminum, or fiberglass, and each type is capable of withstanding sudden temperature changes.Īrguably, the two most popular HVAC tapes are mastic and aluminum foil tapes because they perform well in humid conditions and their adhesives bond to most surfaces.Ĭombining mastic sealants with HVAC tapes is a standard practice among HVAC technicians because it offers a durable sealing solution for a leaking system. This sealant is also available in the form of tape that enables technicians to seal unapproachable segments of HVAC systems. HVAC technicians utilize mastic sealant to treat warped or worn-out connections and seams in the HVAC system. Whether the air or the refrigerant is leaking out of the system, you can stop it with a sealant or an HVAC-rated tape. ![]() The costs of replacing the entire ducting system every time it starts to leak are too high, but on the other hand, leaks increase the system’s energy consumption and lower its efficiency. ![]() You should check out our article on mini-split systems if you don’t have a conventional HVAC system at home. In this guide to the best HVAC tapes, we’re going to examine the features these tapes should have and help you choose the model that will get the job done. However, a professional HVAC toolkit should also include film and electrical tapes and general-purpose duct tape. The tape you use needs a wide temperature rating, excellent water resistance, and a high level of adjustability.Ĭonsequently, only HVAC rated tapes are approved for professional repairs of HVAC systems. Using duct tape to fill holes in the ducting or strengthening the air conditioning cables is forbidden. Our guide to the best HVAC tapes will help you figure out which type of tape you can use to perform minor repairs to the HVAC system. Sometimes repairing an HVAC is as simple as sticking tape over the leaky part of the system, but you can’t use just any tape.
