How we ensure you get the best service?

  • We install based on the state/city code.
  • We make sure that the duct isn't installed near hot equipment.
  • We make sure there is not direct sunlight on the duct itself as that can cause degradation.
  • We install for the now, not for any future changes down the line - as that cause cost more, and is not recommended.
  • We ensure that the hanger being used it four feet and we use a duct saddle.
  • We use approved materials only (i.e., tapes, clamps, etc).
