The condition of your ductwork can play a large role in the quality of the air coming from your HVAC system.
The problem is that many people do not know when they should be replacing their HVAC ductwork. If you are one of these people, you need to know what signs to look for that tell you that the ductwork should be replaced.
The Age Of The Ductwork
As your ductwork ages, problems can start to arise. Ductwork will generally last between 10 and 15 years before problems start to make themselves known. If your ducts are older than 15 years, you need to have them replaced.
At this age, gaps could start to form in the ductwork. There is also a chance that sections could start to collapse at this age. Of course, you should have the ductwork looked at by a professional to determine what needs to be replaced.
High Energy Bills
A lot of people assume that high energy bills associated with HVAC use tell them that they need to replace the HVAC system. While this is often the case, if you have an energy efficient and newer system, your ductwork might be the issue. In these cases, you might be losing energy through leaks in the ductwork.
To test if this is the case, you will need to hire a professional to run a blower door test. If the leaks are small, you will not have to replace the ductwork as they can be sealed. However, if the leaks are larger, sections of your ductwork may need to be replaced. After this, you will generally see a reduction in your energy bills.
Poor Indoor Air Quality
Another sign that your ducts need to be looked at will be poor quality air inside the building. If there are gaps and holes in the ductwork, pollen, dust, and other pollutants are able to bypass the filtration system in your HVAC. This will cause the quality of the air to drop and result in allergies, irritated eye, and other health complaints.
Poor air quality can also be caused by the spread of mold through the ductwork. When this happens, there will be an unpleasant odor coming from your HVAC system. If you have these issues, you need to contact an HVAC professional as soon as possible because mold spread can be extremely dangerous. And if it is not fixed immediately the consequences can be catastrophic.
If you hear strange noises coming from your HVAC system, you need to consider having the ductwork replaced. The noises you might hear including rattling and shaking. If there are other types of noises like explained on https://primehvacrepairservice.com then surely you will need to have your ducts looked at immediately.
Rattling from the ducts will generally be a sign that the ductwork is loose and needs to be secured correctly. However, if you hear a whistling sound coming through the ducts, this is a sign that there are holes in the ducts. In these cases, you will need to have sections of the ductwork replaced.
There are many signs that tell you it is time to replace your ductwork. This will include high energy bills, the age of your ducts, poor indoor air quality and unusual noises coming from the ducts.
