What Is Involved in Duct Testing?

You may not be aware of how important your home’s network of ducts is. It’s responsible for bringing conditioned air from your heater and air conditioner into the rooms throughout your house, and it also circulates air through the intake vents and into the HVAC system. In order to do its job effectively, the ventilation system must remain in excellent condition with an airtight seal. If this seal develops leaks because of breaks, holes, corrosion, and loose connections, it will cause a plunge in air pressure that will severely affect your home’s comfort. It will also allow contamination to enter the ventilation system, and this will damage your indoor air quality.

Through duct testing you can find out about the integrity of your home’s ductwork. Professionals will come to your house and perform tests that will locate where your ducts have air leaks that are lowering efficiency and endangering your air. After duct testing is finished, the experts will know exactly what needs repairs and how to take care of those repairs.

Here’s what happens during duct testing

Duct testing involves sealing off an entire ventilation system and then pressurizing it in order to determine how airtight it is. The technicians determine how much air pressure is escaping from the ductwork and then trace down the locations so they can repair or seal them.

The first step in duct testing is to close off all the vents and registers into your home so that the only place air pressure can escape is through leaks along the ducts. A vacuum is attached to the ductwork near the HVAC unit and the whole ventilation system is put under pressure. Using a duct leak tester, the technicians learn how much pressure is escaping from the ventilation system, and this gives them a sense of the scope of the problem.

Once they have determined the total leakage in the ventilation system, the technicians move across the ducts with a pressure sensor to pinpoint the actual leaks and measure how much they air they are losing. Based on these findings, the technicians will recommend the work necessary to make the ductwork airtight once more. It can involve mastic sealing, metallic tape, or sometimes full duct replacements.
