Your air ducts work with both your furnace and air conditioner to provide heating and cooling throughout the year. However, your ducts, just like all other parts of your HVAC system, can lose their efficiency over time, which can affect how well your HVAC system can moderate the temperature within your home. Knowing what some of the more common symptoms of damaged or malfunction ducts are and what underlying problems they indicate can help you identify and diagnose problems quickly, so that an HVAC professional can service your system and get things flowing properly again as soon as possible.
Rising Energy Bills
Though it may be caused by a range of different issues with your HVAC system, any sort of steady or significant uptick in your monthly energy costs. Ducts that have sprung a leak can let hot air out of, or into, your air ducts, reducing the overall effectiveness of your HVAC system and forcing your furnace or air conditioner to work for longer periods of time to reach its programmed temperature. If this is the case, you'll likely notice that the air flowing out of your vents is not as hot or cold as the thermostat would suggest, and your home may suffer from drafts or areas with uneven temperatures as well.
Another sign that is commonly associated with air duct issues is the presence of strange sounds. Banging, rattling, whistling, and grinding noises coming out of your vents when your HVAC system kicks into gear usually point to loose connections within your ductwork, where individual panels of metal may be rubbing against one another. All of these sounds can indicate an air leak and will likely only worsen with time as the metal grinds itself down, so having a professional inspect your system to determine where the noises are coming from so that they can be fixed can help restore the efficiency of your system again.
Finally, the last common symptom of ductwork that desperately needs to be serviced is if you find that there is very little air coming out of the vents and registers throughout your home at all. This usually indicates that your ducts are clogged with dust and debris, which can happen normally over time with regular operation. You'll have to have the air ducts cleaned out, and likely will need to replace the air filter in your HVAC system as well, to ensure that your unit is able to return to its intended airflow capacity.
