Duct Pressure Testing

Duct pressure testing is a diagnostic procedure performed by a certified professional to measure the amount of leakage in a duct system and air handler. The test can help you identify:

Areas where air is leaking from the duct system
Opportunities for duct sealing
The amount of duct leakage in your home
Whether your home is within the recommended flow standard

Duct pressure testing is an important tool for improving the energy efficiency of your home. By identifying and sealing duct leaks, you can reduce your energy bills and improve your comfort.

How Does Duct Pressure Testing Work?

Duct pressure testing is performed by a certified professional. The professional will attach a duct testing fan and manometer to a central return duct. The fan will create a negative pressure inside the duct system, forcing air to leak out through any gaps or cracks.

The professional will then use a smoke pen or other tool to identify the areas where air is leaking. They will also measure the amount of air leakage in cubic feet per minute (CFM).

The results of the duct pressure test will be used to make recommendations for duct sealing upgrades. These upgrades can include caulking, sealing around duct joints, and using mastic paste or HVAC foil tape.

Why is Duct Pressure Testing Important?

Duct leaks can waste energy and make your home less comfortable. Additionally, it can bring in allergens. Air that leaks from the duct system can:

Enter the living space and make it feel drafty
Escape to the attic or crawlspace and increase the risk of moisture problems
Reduce the efficiency of your HVAC system and make it work harder to heat and cool your home

Who Should Get a Duct Pressure Test?

Anyone who wants to improve the energy efficiency of their home should consider getting a duct pressure test. This is especially important for homes that are drafty or that have high energy bills.

Duct pressure tests are also required for new construction homes in many areas. This is because duct leaks can lead to moisture problems and other issues.

Duct pressure testing is a valuable tool for improving the energy efficiency of your home. If you are looking for ways to save money on your energy bills and improve your comfort, consider getting a duct pressure test.

Here are some additional tips for improving the energy efficiency of your duct system:

Insulate your ducts. This will help to prevent heat loss in the winter and heat gain in the summer.
Seal all duct joints and penetrations. This will help to prevent air leaks.
Use high-quality duct materials. This will help to ensure that your duct system lasts for many years.
Have your duct system serviced regularly. This will help to identify and repair any leaks or other problems.
