Plug Leaky Ducts
Sparen Sie viel Geld mit ein wenig Klebeband und verstemmen Sie
Das Abdichten von undichten Fugen in Heizungs-, Lüftungs- und Klimakanälen ist ein einfaches, billiges DIY-Projekt, das Ihre Energiekosten um Hunderte von Dollar pro Jahr reduzieren kann.
Zwei Möglichkeiten zum Abdichten von Fugen

Tragen Sie eine Raupe aus Silikon auf beiden Seiten der Kanalfuge auf.

Runde Kanäle mit Alufolie kleben, nicht Klebeband.
Wenn Wärme oder Kälte aus den Kanälen entweicht, insbesondere im Keller und auf dem Dachboden, muss der Ofen oder die Klimaanlage länger laufen (und mehr Brennstoff verbrauchen), um den Wohnbereich des Hauses auf die Temperatur am Thermostat zu bringen.
Unser Heizungsfachmann gab zu, dass er nie gedacht hätte, dass das Austreten von Leitungen ein großes Problem darstellt, bis er ein thermografisches Bild sieht, das zeigt, wie viel Wärme an den Kanalverbindungen verloren geht. Heute glaubt er an die Kanalabdichtung.
Dichtungskanalverbindungen sind ein DIY-Projekt. Es ist nicht nur einfach - es ist billig! Kaufen Sie einfach aluminiumfarbene Silikonabdichtungen und verkleben Sie jede Verbindung in rechteckigen Kanälen (reinigen Sie die Verbindungen zuerst mit einem Haushaltsspray-Reiniger und einem Lappen, um den Staub zu entfernen). Verwenden Sie die Dichtungsmasse, um die Abnahmestiefel zu jedem Abzweig zu versiegeln. Kaufen Sie ein UL181-Aluminiumfolienband mit hoher Temperatur im Kanalabschnitt eines Heimzentrums und verwenden Sie dieses zum Abdichten der Verbindungen von runden Rohrleitungen.
Verwenden Sie niemals gewöhnliches Klebeband. Trotz seines Namens ist es nicht für die Kanalabdichtung zugelassen und hält langfristig nicht gut.

FAQ - 💬
❓ How do you seal a leaky air duct?
👉 2:047:30How to Seal Leaky Ductwork | Ask This Old HouseStart of suggested clipEnd of suggested clipSort of a rubberized cement to seal up the joints. The mask is applied with a brush at any placeMoreSort of a rubberized cement to seal up the joints. The mask is applied with a brush at any place that air could ever leak. Out it's messy but it's really effective.
❓ How do you seal a duct opening?
👉 How to Seal a Duct Boot to the Ceiling
- Seal all sides of the duct boot to the gypsum board with spray foam or caulk (Figures 1, 2, and 3). Apply mastic or metal tape to all duct seams and joints.
- Cover boot with insulation.
- Add insulation to the specified attic insulation depth.
❓ Should you seal ductwork?
👉 HVAC ducts that leak heated air into unheated spaces can add hundreds of dollars a year to your heating and cooling bills. Sealing and insulating ducts increase efficiency, lowers your energy bills and can often pay for itself in energy savings.
❓ How do you fill gaps around ductwork?

❓ Can You Use Flex Seal on AC ducts?
👉 Environmentally Safe Flex Seal Is Your HVAC's Best Friend One application of Flex Seal offers the kind of protection against leaks and corrosion,the main culprits when it comes to HVAC ductwork degradation.
❓ Can I use foil tape inside duct?
👉 When sealing the air duct, you can use a mastic sealant. If you prefer using tape, the aluminum foil tape can help you get the work done. However, as with most HVAC related systems, it's always advisable to hire a professional when looking for more than just a simple seal with aluminum foil tape or mastic sealant.
❓ Can You Use Flex Seal on ductwork?
👉 Flex Seal leaves behind a smooth flawless surface that protects and prevents any kind of leak problems from developing in your ductwork.
❓ Can you seal ductwork from the inside?
👉 Sealing the leaks from the inside ensures more of that conditioned air moves where it should. You'll have more airflow in your living space, and your system won't have to strain to keep you comfortable. Leaks in your ducts can reduce your system's effectiveness by as much as 20%.
❓ Should ducts be airtight?
👉 Having properly sealed ducts can balance the air temperature in your home because air will be able to reach each room, creating a more comfortable living space. Having properly sealed ducts can also reduce your utility and energy costs because HVAC system won't have to work so hard.
❓ Why is water dripping from my ductwork?
👉 Condensation in the Air Ducts Both in the heating and the cooling season, condensation can form either on the outside or the inside of ducts that are poorly insulated. This is the most common cause of water leaking from the HVAC vents.
❓ Can I use duct tape on HVAC ducts?
👉 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 in energy loss and expensive heating and cooling bills.
❓ How do you fix a leaky ductwork?
👉 The cure for these duct leaks is simple: reconnect leaky duct sections (photo at left). In addition to making a mechanically sound connection between duct sections (sheet metal screws, mechanical fasteners, nylon tie strips), we use metal foil tape to complete the seal on connected metal duct sections.
❓ What happens if you have a leak in your air ducts?
👉 If there is a leak, however, these materials can make it out of your ducts and get directly into your indoor air. This can be especially noticeable if you have a finished basement where your ductwork is up above you, although air quality may be affected in other areas of your home as well.
❓ What are common defects found in air conditioning ducts?
👉 This article continues discussion of common defects found in air conditioning duct work such as loose or leaky duct connections and their effect on the air conditioning or heating system.
❓ How do I know if my HVAC ducts are leaking?
👉 These unusual sounds can also alert you to the possibility of a duct leak. Pay particular attention to strange noises, such as whistling and metallic rattling due to metal ductwork that’s leaking or loose. It’s not realistic to expect your ductwork to be entirely free of dust and debris.
