The best tool for cutting metal ducts depends on the duct's shape and thickness. For round ducts, a duct cutter provides accurate, clean cuts. Reciprocating saws equipped with metal-cutting blades are versatile and suitable for both round and rectangular ducts. They offer speed and precision, especially for thicker metal. 

Tin snips are handy for intricate cuts or smaller ducts. However, an angle grinder with a metal-cutting wheel is powerful and efficient for large or thick metal ducts. 

Professionals ensure durability by selecting high-quality materials, precise fabrication, and proper finishing techniques. They perform meticulous installation and provide maintenance advice to extend the lifespan of metal installations.

Some states require welders to be licensed and certified, while others don’t. However, it’s always a good idea to hire a licensed welder, regardless of requirements in your area, especially if you need welding for structural components of your home or gas lines. Licensed welders have gone through training and testing to prove their skills, so they’re less likely to make a mistake that could be detrimental to your home. Use Angi’s state licensing tool to determine whether your potential hire has a welding license.

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.
