Testing Ducts: Why It’s Important
Leaky ducts are a serious problem for a ventilation system. It may sound as if a few leaks can’t be too harmful. But up to 30% of the cooled and heated air passing through ducts can be lost to places like the attic and between walls because of leaks. That’s a lot of money going to waste! Leaks are a common problem, as well. Poor duct installation is the main culprit, but high air pressure, insects, water, and construction damage can all contribute.
Duct testing is designed to find out if a house has leaky ducts, how bad the problem is, and how best to fix it.
How to Test Ducts—The Professional Way!
Testing ducts requires first sealing off the ventilation system and then raising the inside air pressure with a power vacuum. Using manometers, the duct testers can then measure how fast the pressure inside the ducts starts to drop. The faster the pressure declines, the more leaky the ductwork. Using these tools and their training, the duct testers can identify how much work they have to do to restore the integrity of the ventilation system and stop the wasteful loss of air.
Next Comes the Duct Sealing
No, you can’t seal ducts with store–bought duct tape. Ironically, duct tapes work on just about everything—except ducts. You won’t be able to find all the leaks and access them on your own anyway. The ventilation system experts on the job have the equipment to find and seal up the leaks. A common method is to apply mastic, a resin–based sealant, to the leaky duct sections. Sometimes service experts use metallic tapes, or a combination of both. As long as you make sure you have a certified and insured professional on the job, you can be confident you’ll have your ducts put back in shape.
