Duct Sealing

If your New York home was built before 1985 and you have high bills or comfort issues, the air duct system is a likely source of the problems. Insulation & HVAC upgrades are only part of the solution. As much as half the conditioned air you purchase every month could be ending up in the attic, basement or crawlspace.

If your home has metal ducts, our professional HVAC contractors can seal them and significantly reduce the air loss. When older New York homes were first built, energy efficiency was not on the list of priorities. We see this problem every day and, without fail, major comfort issues are always related to ductwork leakage, poorly installed insulation or the mechanical system.

How do you know if your ducts leak?

If you have metal ducts in original condition - then they leak air. The only question is how much. During our energy audits we closely examine the ducts by pulling back the insulation wrap in various locations and using a smoke puffer with visual assessment to determine how bad your ducts are performing. Most of the time you can clearly see the leak points once the wrap has been removed. As part of our audit report you will receive photos showing the damage. On homes with old metal rigid duct the leakage is typically over 40-50%.

Where Does The Duct Leakage Come From?

Duct leakage is due to several factors:

The main cause of duct leakage is that the connections were never sealed when the ducts were first installed. (Remember, back when energy was cheap, plentiful and nobody really cared about their utility bill)

There is often damage or separation when the house settled over the years. (often crushed or separated pipes from 3rd parties doing work in the attic)

Also, the ducts are usually only insulated with R-3 insulation which results in a significant amount of heat gain/loss as the air travels through the ducts in your attic or basement/crawlspace. When we foam seal old ducts the insulation is upgraded to an R12.
