If the ductwork inside your home loses integrity, it can cause some major problems for your heating system. Since the ductwork is designed to be hidden from sight, if your ducts have become damaged, it is very difficult to identify. Fortunately, there are some signs that you may have a duct sealing issue that requires attention.
Signs of Ductwork Damage:
Even though your ducts are likely to be hidden behind walls and above ceilings, there are still some signs which may be exhibited if there is a problem. Although you are not likely to see a leak with your naked eye, if there is a drop in airflow or you can smell a strange odor when your system is running, the chances are you have some degree of ductwork damage. When the ductwork has become compromised, your heating system will be unable to operate at optimum performance. You may notice hot or cold spots in different areas of your home, or you may feel that the system is not able to maintain your preferred temperature.
The Implications of Leaky Ducts:
Although a little air leak may seem like a very minor issue, it can have some serious consequences for your system and home. Ventilation systems are designed and manufactured to be completely airtight. This seal is necessary to maintain the air pressure as air is driven from the furnace blower fan or heat pump to the registers inside the room. Even a minor leak can trigger a massive drop in air pressure, and leaking ducts could result in up to a 30% drop in your heating efficiency.
This type of drop in efficiency can affect your heating system in a number of ways. These include;
Cold Spots: When the rooms inside your home experience a drop in warmth, it is usually due to leaks in the ducts connected to the vents. If you have not had previous issues with cold spots inside your home, it is a sign of a ductwork issue, and you should call in a professional.
Higher Heating Bills: As the heater starts to lose air pressure, the system will attempt to work harder to compensate for the need to heat the colder air surrounding the ducts. This will lead to greater energy use and higher heating bills. Until the leaks have been sealed, you may notice your heating bills suddenly and steadily increasing. So, if your heating bill has come as an unpleasant surprise this month, it could be worth investigating if you have a duct leak.
Increased Repair Demands: When your heating system is forced to work harder due to the escaping air, it will place it under greater strain. This strain will be shown in the need for more frequent repairs. If the issue is not addressed, in the long term it will cause premature wear and tear, compromising the lifespan of your system.
Compromised Air Quality: Finally, a leak can also allow dirt, dust, and other debris to enter the ducts. This can not only cause damage to the heater as it is allowed entry to the cabinet and mechanical parts, but it can also compromise your indoor air quality. If you notice that allergy symptoms have begun to flare up, you need to change your air filters more frequently, or you just feel under the weather, you should consider having your ducts checked for leaks.
