Problems that Can Develop in Old and Poorly-Installed Home Ductwork

Last updated 4 years ago

The ducts connected to your heating and air conditioning system are responsible for distributing conditioned air throughout your home, and if they have not been installed properly you’ll face a host of issues. What appear to be seasonal allergies can actually be caused by problems in your ductwork, and what you may think is a furnace issue could instead be an air leak.

Energy Loss

  • As air moves inside the ducts, it slows down. This happens to all ductwork, but it can become a problem with poorly-designed ducts. Ducts need to be calibrated when first installed in order to provide optimal airflow. This means that the ductwork should be arranged in the most efficient layout for air delivery. Haphazardly installed ducts that move around obstacles or are too long will increase the loss of energy that occurs due to friction. Older ductwork that has begun to sag can also cause this issue.

Uneven Heating and Cooling

  • Another symptom of ductwork that is not properly sized or installed is uneven temperatures in your home. Rooms that are consistently too hot or too cold may be receiving too much air while other rooms are neglected. Improper design can cause ducts to deliver all the heating energy from your furnace to one area of your home. This kind of problem can potentially develop in older ductwork if supports fail and allow ducts to shift.

Leaks and Indoor Air Quality Problems

  • Leaky ductwork can increase energy loss and cause uneven temperatures as well. Ducts installed more than 10 years ago will not typically have the same connection methods as today’s energy-efficient ductwork. Metal tabs were used to join supply ducts together, which often resulted in leaks the very first time the HVAC system was activated. Leaking ducts present a health issue as well, as contaminants like dust and allergens can accumulate and be distributed throughout your home, reducing your air quality and causing allergy-like symptoms.

Repairing and improving your ductwork can reduce your energy costs, increase your comfort, and boost your indoor air quality. To have your ductwork analyzed, call Aladdin Air Conditioning & Heating, Inc. at our Thousand Oaks office at (805) 273-4320.
