Quality Of The Product

Flex ducts prefer colder places. That is why if you are living in a hot region and had it installed in areas such as the attic, your system will most likely deteriorate faster.

Benefits Of Duct System
Having properly installed ductwork in your home lets you have a comfortable, even temperature throughout the season. Not only that, but it also comes with so many benefits. Starting with decreasing the harmful substances in your house.
The ductwork helps distribute the air from your HVAC equipment. This includes transporting the conditioned air back in and blowing any excess amount outside.
This helps reduce harmful byproducts of heating and cooling systems such as carbon monoxide. The ductwork guides the harmful gas out of your home so it doesn't build up to dangerous levels.
Carbon monoxide replaces the oxygen in your body when inhaled. Of course, oxygen is important to keep us functioning and alive, so we want to minimize the level of carbon monoxide in our homes as much as possible.
Another advantage is that insulated ductwork saves you money. How? Since it helps circulate and disseminate the treated air, your HVAC equipment does not need to work as hard to maintain the temperature throughout the areas of your home. This means it uses less energy which will reflect in your electric bill.

Signs You Should Replace Or Repair Your Flexible Ductwork
You need to be cautious of these symptoms. You must be needing an immediate repair or replacement if you have the following:
- Making unusual, loud noises. The fiberglass or plastic joints are probably damaged, resulting in rattling or hissing sounds.
- Increase in the electric bill. As we have mentioned before, an insulated air duct helps in reducing your monthly bill. This is why a leak or hole in one of its parts may reflect in your energy consumption since your system needs to work harder for the air that escapes.
- Some parts of your home are not heated or cooled. Another implication is that your system's got a leak in it since the air might have been seeping out of the hose before it could even reach that area in your home.
- There is more dust than usual. If you have holes in any spot of your duct, the dust particles will most likely enter through it and will be flown towards the vents.
To know which solution applies to you, consult a professional and have your duct system checked.
