Featured Ducts And Vents Heating Cooling

Why faulty ducts and vents waste your energy (and money)

Heating and cooling systems, also known as HVAC systems, keep your home at a comfortable temperature year-round, providing heated air in the winter and cool air in the summer. The ducts and vents that deliver this air to the various rooms in your home are not something that you think about often. But leaking ducts can cost you money, and dirty ducts may be the cause of allergies.

5 facts about ducts and vents you should know

The average American family spends 44 percent of the energy bill on heating and cooling the house. A poorly designed or leaky HVAC system can increase that cost by 10 percent. Here are some things you probably do not know about your HVAC ducts and vents that could waste your money:

  1. Today's ducts are not sheet metal boxes, but insulated flexible tubes.
  2. Get Help Finding:
  3. Sometimes contractors forget to attach the ducts to vents or other ducts, and air is vented into the attic or crawlspace instead of warming or cooling your rooms.
  4. Ducts can be snagged on exposed nails, causing tears or holes that leak air.
  5. Dirty ducts and vents can cause allergy symptoms or breathing problems for family members.
  6. And most surprising of all: duct tape is not good for sealing ducts. It will dry out and fall off over time.

Common problems

If you have a new home with a room that is too hot or too cold, there may have been an oversight in construction that failed to connect the duct to the vent in that room. If you have been in your home for a few years and your energy bills suddenly rise, you may have a leaking or kinked duct. In either case, you should call a professional HVAC service company. They will perform an inspection and correct any problems, make sure that your ducts are properly sized and routed for best airflow, and replace duct tape with more reliable sealing methods. Even if you don't have a problem, it's a good idea to get your HVAC system professionally checked every year.

Keep it clean

The best way to keep your HVAC system operating efficiently is to replace your filters regularly. A clogged filter makes the whole system work harder and costs you money. Should you also have your ducts cleaned periodically? Research by the U.S. Environmental Protection Agency (EPA) indicates that it is a good idea under certain conditions:

  1. If ducts and vents are clogged by visible dust and debris
  2. If ducts are infested by vermin (insects or rodents)
  3. If there is visible mold growth in the ducts
