HVAC Ducts, and Why They Matter

Your home's duct system channels conditioned air to the vents around your home

HVAC Duct System resized

Duct systems should be:

  • Efficiently designed
  • Undamaged and well maintained
  • Free of humidity issues and microbial growth

Common Duct System Issues


Escaping air - Holes, gaps, or poorly sealed connections can allow conditioned air to escape into unwanted spaces in your home, such as your attic or crawl spaces.

Poorly designed or installed - Duct systems may have oversized or undersized ducts, or duct runs that are longer than needed.

New system, old ducts - Homes may have a new HVAC system, but the original ducts from when the home was built.

Unwanted odors - Ageing or damaged ducts can lead to unwanted microbial growth in the system, stale smelling air, and possibly even foul odors!
