As homeowners begin to sense a compromised comfort in the indoor, the first thought goes towards the HVAC system. It is true that for most of the times, the reason behind compromised indoor comfort is the HVAC units but it is not always the case. Sometimes, the units are all okay but it is the ductwork that aches. Did you know that even small leaks and cracks can devoid you of 20% conditioned air rising the use of the appliances and the energy bills? It is, therefore, important to not be careless towards this issue and fix the problem as soon as it is observed.

All homes usually have one these three duct types;
They either have a metal sheet or an insulated flexible or insulated duct board. In the modern homes, the duct most commonly installed is of the flexible sheet. This, though easy to install and flexible to accommodate is hard to take care of. Not only that it is easily damaged but is also relatively less energy efficient. Whatever the duct type is, once it gets the leaks, the situation keeps on getting worse; the leaks widen and cracks expand resulting in more loss of energy and higher energy bills.
There are some signs that can help detect ductwork leaks;


Sings of a leaking ductwork 

* If your utility bills suddenly start to escalate and the HVAC units are working fine, it's the ductwork that you should check
* If there are rooms or areas of the home that are becoming difficult to warm/cool
* Indoor getting stuffy
* Air filters frequently getting dirty
* Dents or cracks in the ductwork
* Discolouring ceiling could also be an indication of leaking ductwork
* Home getting unusually dusty

These sings can help you find out the leaks and cracks. But you should also get to know of the primary causes of duct leaks.

Causes of Ductwork leaks? 

* Ductwork needs to be renewed after its lifetime is over. If you have an old home with an old ductwork installed, chances are you'll have leaks frequently
* Many people close the vents in the unused rooms. Doing so keeps the air trapped in the ductwork resulting in cracks
* If you have rats and rodents at home and a foil or flexible ductwork, you are at a constant risk. They can leave multiple cracks and leaks in your ductwork anytime
* A professional installation always matters. So if you had chosen a wrong tech who left loopholes, the loose connections in the ductwork would cause leaks
* Some ductworks need to have insulation in order to be properly efficient. Improper insulation may cause leaks

If you are suspecting a ductwork leak, do the following;
Take a piece of paper or burning candle and move it closer to the areas that you think have leaks. If the candle flickers or the piece of paper moves rapidly, there are leaks. Seal the leaks with a duct tape. However, there would be times when you'll find it difficult to find the leaks or to fix them on your own. When that happens, never overlook the matter and call a professional to check the ductwork to find and fix the problem.
