To guarantee a secure seal and ensure your ventilation system is properly maintained, it is important to hire technicians certified by National Air Duct Cleaners of America (NADCA), such as those from Alpha Air. Sealing ducts is a task that can be done without the need for special tools or skills, but the right materials and techniques must be used. Putty is an excellent choice for sealing air ducts, as it is usually cheaper than tapes and other types of sealants, yet just as effective in creating a reliable seal. It is recommended that you wear disposable gloves while using the putty.
When it comes to air sealing and duct sealing, there are a few essential points to consider depending on the level of work being done. You probably don't need this type of service unless your ducts are very old and difficult to repair or replace. If you have broken ducts that affect the efficiency of your air conditioning system and reduce indoor air quality, call experts who have the right equipment to do the job. The following are some common types of tools and equipment used in the inspection, maintenance, and restoration of heating, ventilation, and air conditioning systems.
Place the sealing cushion around the cable or duct and insert it into the duct inlet. Wrap each cable with sealing tape. Fill in the gaps with balls of sealing tape. Despite its name, duct tape is a terrible tool for sealing ducts (temperature changes mean it will likely come loose again in a few days).
The main differences between putty for sealing ducts and putty for plumbers are the ingredients used to make it and their melting points. Depending on your specific situation, you can use a putty to repair small holes and cracks in metal ducts, or a sealing putty to repair larger holes in metal or flexible ducts. Start by sealing air leaks with sealing putty or metal tape and isolate any ducts you can access (such as those in attics, mezzanines, unfinished basements, and garages). Inflate the sealing cushion through the tire valve with a standard tire inflation tool, following the safety advice in document WO 05, part 0, and the installation instructions in document WO 05, part 3.If you are looking for an alternative solution to sealing air ducts, consider hiring an authorized professional who specializes in this type of service.
