Many people do not know where the air duct system is in their houses. Their houses are old; thus, the HVAC ductwork was placed long ago and is also aging.
Little thought is given to the ductwork after initial HVAC installation. Are you in a house with old ducts and wondering if you should replace them?
In most homes, the HVAC ducts are made to last about 15 to 20 years. After this time, the ducts will likely be quite damaged and need replacement.
They are generally made of plastic or fiberglass, and these materials get damaged over time. If your HVAC ductwork has remained intact for about two decades, it is time to consider replacing it.
Signs That You Need Air Conditioning Duct Replacement
If you are replacing your old HVAC system with a new one, it might also involve replacing your ductwork. Most old ductwork does not go well with the modern-day high-efficiency AC unit.
The old ducts may be undersized, start leaking and break down a lot when matched with today’s ultramodern HVAC systems, which is why they need replacement. Here are other telltale signs that your ductwork requires replacement.
You can expect some noise whenever your HVAC is heating or cooling air in your house. However, it should not make loud rattling sounds.
Neither should the HVAC duct work vibrate too much when functioning. If this is happening, you may need to inspect your ducts.
The joints in your ducts are made of fiberglass or plastic. When these ducts are damaged, the materials that make the ducts produce whistling or rattling sounds.
Leaks in the ductwork also produce loud sounds when air flows through them. Such ducts need to be replaced since waiting only makes the noises worse.
Different room temperatures around the house
You might notice that some rooms are at times warm while others are cold. These temperature zones can arise from damaged ductwork that transfers air differently to the different rooms.
If the temperature differences are rather pronounced, you need to inspect your ducts immediately.
There could be big holes in the ductwork that causes air to escape into the rooms without serving its purpose of heating or cooling.
High Utility Bills Because Of Air Duct Air Escape
Air ducts are always leaking a little air here and there. But when about 20% of air escapes, your HVAC unit is compelled to work harder to keep temperatures right.
All the preceding will be reflected in high energy bills from overworking the HVAC. To keep your energy bill down, inspect your ductwork for leaks and have those with large holes replaced.
Dust Comes Out Of The Ducts
Dust is everywhere since it is impossible to get rid of it completely. However, if there is too much dust in your home, it could arise from damaged ducts which need to be replaced.
What happens is that dust from the outdoors gets into your ductwork through leaks and other holes. This dust stays in the ductwork, which flows to the vents and gets dispersed around the house.
Pests, Mold, And Mildew
If you smell mold and mildew a lot in your house, it could be because of poorly insulated and poorly connected ducts.
Different temperature zones around the house can also cause mold and mildew growth. For instance, condensation can form when warm air travels through cold ducts. This humid environment is a good breeding ground for mold and mildew.
Leaks and holes also allow rodents and other pests such as bugs to enter. Over time they can be a real headache when they establish colonies.
These pests can further damage your ductwork as they thrive and cause blockages in the air duct system.
When you notice blockages and other signs of pest infestation, seek professional help to eliminate the pests and replace the damaged ductwork.
Vents drive the air around the house. If the air happens to be dirty, it will leave dirt on the vents.
The vents get dirty over time because of the buildup of dirt, dust, and other contaminants such as pets’ hair.
Dirty vents signify that your ductwork is wallowing in dirt and debris. Inspect the air conditioning system and replace all damaged ducts.
Tangled Ducts That Needs To Be Replaced
Heavy objects such as stones or logs may fall on your ducts, causing them to twist in a weird way that restricts airflow.
If you see ducts twisted at some angle, replace them before they become a source of other problems.
Having respiratory problems
If you have persistent and weird respiratory symptoms not associated with colds and flu, they could arise from poor indoor air quality due to damaged ducts.
Your symptoms could arise from the dust, pollen, pet hair, cigarette smoke, and other allergens in the air circulating in the house. Such damaged ducts need replacement as well.
What Is The Cost Of Replacing Air Ducts?
Duct replacement can only properly be done by an expert. It takes a lot of work to replace ducts. The ducts are also typically found in very tight spaces such as the attic.
Temperatures in such a space can often hit three figures, making working in the space uncomfortable.
These difficulties that you encounter when replacing ducts are another reason why an expert is best placed to replace them.
The ductwork installation costs varies based on several factors. These costs are about 40 to 60% of air conditioning equipment project costs.
