Common Air Duct and Vent Problems
Not sure why you may have air quality issues? Listed below are some common problems involving ductwork.
Problem: My air ducts provide weak or insufficient air flow
Explanation: This could be caused by ductwork that is improperly routed, unnecessarily long or has excessive bends; or vent piping that has been crimped, crushed or damaged. Homeowners can sometimes identify a problem by inspecting their ductwork for signs of damage or wear. However, the ducts are often hidden in floors, ceilings, and walls, making them impossible to examine without help from an HVAC technician.
Problem: My duct system wasn’t designed properly
Explanation: According to the National Comfort Institute, the average duct system in the U.S. is only 57% efficient. One of the biggest reasons for this is that a poorly designed and installed system cannot supply and return the required airflow to heat and cool your house effectively – even if your equipment is sized correctly and functioning properly.
Problem: My air ducts are leaking
Explanation: The average home loses about 20% to 40% of the air that circulates through its ducts, causing major inefficiencies in your heating or cooling system. Investing in getting your ducts sealed ensures you will lose less air, meaning your system won’t be overworked from trying to bring your rooms to a comfortable temperature. Leaky air ducts can also allow pollutants to enter your home, negatively affecting your indoor air quality.
Problem: I have loose or poorly sealed registers and grills
Explanation: Air that you have already paid to heat or cool can escape your ducts before it ever reaches your rooms if your registers are not sealed or are not sealed properly at the duct connection. Checking these connections can help prevent your HVAC system from unnecessarily working harder to counter the effect of poor seals.
Frequently Asked Questions
Q: What are some signs that I may have ductwork problems?
A: There are several signs that you may need to reassess your ductwork, including uneven temperatures throughout your home, excessive dust, air that feels stuffy, noises emanating from ducts or behind walls and heating bills that have spiked (or are higher than you suspect they should be).
Q: What are some tips for improving air duct efficiency?
A: Never allow your air vents and registers to be blocked by furniture or other household objects. You should also regularly clean any vents that have dust or debris on them.
Q: Why should I keep my ductwork well maintained?
A: Maintaining and cleaning your ductwork helps your system run more efficiently, which extends the life of your heating and cooling equipment. And, of course, the cleaner air is far healthier for those who suffer from allergies or asthma – which is one in six Americans.
Q: Does my duct system really get that dirty?
A: Studies show that in a typical six-room home, up to 40 pounds of dust is created each year just from everyday living. We also generate significant quantities of pollutants and contaminants, potentially including mold and fungi, that are pulled into the HVAC system and recirculated five to seven times per day, causing a buildup of unhealthy elements in the ducts.
Q: How do I fix my duct vents?
A: According to the EPA’s Energy Star program, “Some homeowners choose to take on duct sealing as a do-it-yourself project.” The EPA offers tips for such homeowners, as well as those who choose to work with Heritage for duct improvement projects.
