The standard duct system in an attic loses between 25% and 40% of the heating or cooling power put out by the heating and cooling system, based on the U.S. Division of Vitality.1 Air leakage can happen from holes within the attic ductwork or from poorly linked duct joints. As heated or cooled air is drawn into the attic area by means of holes and poor connections, power {dollars} are used to warmth or cool an unoccupied area. Whereas heating and cooling payments will fluctuate based on adjustments within the climate sample, an surprising improve in power payments might sign a problem with attic ducts.
Evaluating a house’s power utilization to different similar-sized houses also can present useful insights a few house’s power effectivity. Many utilities supply prospects a report that exhibits how a house’s power utilization stacks up in comparison with different close by houses of comparable measurement. Heating or cooling payments which can be increased than comparably sized houses within the space might point out an issue with attic ducts.
An Owens Corning® Air CareTM contractor can establish issues with attic ductwork and suggest options to assist enhance consolation and scale back power payments.2 Resolving issues with leaky ducts also can assist curb the wear and tear and tear on HVAC tools, probably extending its operational life and defending the home-owner’s funding in a high-efficiency consolation system.
Past decreasing power effectivity, issues with attic ductwork can adversely have an effect on the standard of indoor air.

Points with ductwork might typically be detected with a visible inspection — for instance, disconnected ducts close to registers or holes, tears and free joints. However many instances, the problems are tougher to detect. That’s why it’s vital to have an inspection performed by a professional contractor.
Owens Corning® Air CareTM contractors are geared up with the coaching and instruments to judge an attic duct system’s integrity and the general effectivity of the duct system. The contractor will use a fan and strain gauge to conduct a fundamental duct leakage take a look at to measure the extent of leakage in ducts. Thermal cameras will visualize the place air from the ducts is escaping into unconditioned components of the house. The contractor may even assess the airflow price as a duct system’s effectivity is affected by leakage in addition to fan stream. Relying on the findings, the Owens Corning® Air CareTM contractor can suggest an answer to deal with duct points which will contain repairing, sealing or changing a number of sections of ductwork.
Past making certain that ductwork is correctly linked and in good situation, different steps can contribute to comfy and energy-efficient environments. Checking the furnace filter as directed by the producer can scale back put on and tear and assist hold a filter from changing into clogged. Putting in a programmable thermostat might help scale back heating and cooling prices by turning up or down the temperature when occupants usually are not house.
