Spiral ducts are common in today’s commercial settings. They offer a myriad of benefits ranging from longer duct runs to reduced leakage because they have fewer joints. Additionally, many architects ...

Condensation control — Preventing condensation that could damage insulation and other HVAC system components or possibly lead to microbial growth; and Energy conservation — Reducing HVAC system ...

One of the most cost-effective and energy-conserving measures you can take is to insulate duct or pipe runs in the unheated areas of your home. By not insulating these conduits, you are essentially ...

Fiberglass insulation is not airtight. Heck, it will barely even slow air propelled by convection, differential pressure or wind. It is especially helpless against air moving through a leaky pipe ...

Q: I inherited a concrete block building that was then converted into a home several years ago. Part of it has a crawlspace and part is on a concrete slab. The crawlspace is always damp, and the ...

Poor heating of rooms in homes equipped with warm-air furnaces can sometimes be traced to heat loss through uninsulated or poorly sealed air ducts. When ducts run through cold areas such as crawl ...

Inefficient ducts force HVAC systems to work harder, raising costs. Rising heating bills, despite normal usage, may signal leaks or poorly connected ductwork. Upgrading or repairing ducts helps ...
