Leaks in the ductwork of a home are a major problem, and they are unfortunately one of those problems that often goes unnoticed or unrepaired for far too long. The consequences of leaking air ducts can be extremely high, so it’s important to know if your house has duct leakage. You can then arrange for a professional to seal the ducts and restore the integrity of the ventilation system.
Of course, that leads to the question of how to detect if you have duct leakage in the first place. The ducts are well-hidden within a home, so you can’t visually inspect them. But there are other signs you can watch for:
A drop in airflow from the vents
One of the immediate effects of leaks in the ductwork is that
it lowers the air pressure in the ventilation system. Ducts must be kept airtight
to maintain air pressure, and the consequence of a drop in air pressure is that
the airflow from the vents will also drop. If you put your hand to the room
vents and notice the airflow is weaker than normal, it may be duct leaks.
Uneven comfort around the house
Lower airflow will also mean rooms cool down/heat up slower, which will lower comfort around the house. This will happen unevenly: certain rooms will still feel normal, while hot and cold spots will appear in others. Duct leaks aren’t the only cause of uneven comfort, but it’s a serious problem no matter what the source.
Odd odors from the vents
Leaks in the ducts will allow air from closed-in spots of
the home to infiltrate the ventilation system, such as between walls and from the
attic. This will carry a musty and sometimes moldy odor to the rooms.
A rise in energy costs
The biggest chronic effect that duct leaks have on an HVAC
system is that they place more stress on the blower, heater, and air
conditioner. Around 30% of the air moving through the ductwork can disappear
through leaks, and this is air you’ve already paid to heat/cool and push into
the ventilation system. The HVAC system will need to put in extra work to
overcome this deficit—and that means energy bills will rise. If you see steeper
bills to heat and cool your house and you can’t account for the change, you
probably have duct leaks.
Solving the Problem
If you suspect duct leaks, the next step is to contact our
professionals. We will test the ventilation system to find out if it has leaks
and how extensive they are. If you do have leaky ducts, the next step for us is
to seal the leaks. We use a range of methods to ensure your ducts will be
restored to airtight condition once more. (By the way, store-bought duct tape isn’t
a method we use. This “duct tape” is not actually useful for ducts.)
