Air Duct Basics


   (View Demo)

The selection of correct air ducts and duct insulation for your home is as important as the HVAC (Heating, Ventilation, Air Conditioning) system itself. The air conditioner, heat pump or furnace is the heart of the system, but the air ducts are meant to carry clean, conditioned air to where you need it in the home, and to carry away stale and uncomfortable air.

Duct systems vary across the country due to climates and local codes. But the importance of proper selection and installation of duct systems does not change. Poor choices or improper installation can have dramatic impact on the comfort, indoor air quality, and operating costs for the home owner.

The right temperature, right where you want it.

Uninsulated metal ducts can let conditioned air change temperature before it gets to the rooms where you live.

Hearing voices from upstairs?

Your sheet metal air duct system can carry voices throughout the house. The right insulation can keep things quiet.

Maintain a healthy indoor environment.

A sealed air duct system of JM ductboard or Formaldehyde-free™ insulation is your best protection from indoor pollution.
