Ductwork

Leakage

The most prevalent kind of failure that afflicts ducts is leakage. Tears, punctures and detachments of ducts  can lead to a significant drop in efficiency and increase in energy costs – sometimes as high as 30% – because the system will try to compensate for the air that has escaped from circulation. Duct leaks may exist from the time the system was installed, and insulation can settle and move over time due to vibration and gravity.

Pledge: We will check the duct works for leaks and proper insulation.

Contamination

Tears, punctures and detachments of ducts not only bleed air out of the system, but allow dust and dirt to enter the works and collect at a greatly accelerated rate compared to a well contained and intact system. Grime in the ducts accumulates on the surfaces and impedes airflow, clogs filters and worsens the air quality of your home. Filters that more quickly fill up with detritus force the system to work harder to push air through them, increasing energy costs, and replacing filters more often also represents an increased cost in materials and service calls.

Pledge: We will check ducts for points of contamination.

 

Material and Layout Quality Assessment

The qualities of the materials used in your ducts chiefly determine whether the ducts are made to be rigid or flexible, and how resilient they are to leakage, contamination and deterioration. Rigid ducts possess advantages over flexible ducts when it comes to reducing turbulence in the airstream and achieving laminar flow. Additionally, the manner of arrangement or layout of the ductwork plays a part in how efficiently they channel air into and out of the rooms of your home. The rigidity of ducts also favors the best overall plan in duct layout: the straightest, most direct plan that takes the fewest unnecessary twists and turns from the point of origin of warm or cool air to the point of delivery into the rooms of your home, and then back again to start the cycle anew or be vented out of the system. Moving air efficiently through your system pays off in effective heating and cooling and energy cost savings.

Pledge: We will assess your ductwork for its material quality and layout optimization, and advise you on whether your system could use improvement.

Static Pressure

The static pressure of your air conditioning system is its resistance to the flow of air that is fed through it. From the ducts that channel the air into and out of rooms, to the filters and vents that strain and shape the air that flow through them, all of the components affect the column of air within them. Although we often think of air as being inherently tenuous, within the environment of the duct work, it behaves as a mass of air that stands its ground and pushes against an incoming air stream. In order for your system to move air of desired temperatures around your home, the static pressure of the air must not produce too great a resistance, but rather yield to the prevailing air flow. If the static pressure is too high, your system will exhibit reduced performance and energy efficiency, resulting in costlier operation.

Pledge: We will measure static pressure and use it to assess your system’s handling of air flow.
