What Options Are Available to Improve Indoor Air Quality?

Then there’s also the concern of your comfort. Too much humidity in the air, for example, can make your space feel hot and sticky, no matter how well your AC is performing.

How Often Ductwork Should Be Replaced

While ductwork can last up to 20 or 25 years, it’s usually around the 15-year mark that air ducts begin to deteriorate. While air is still flowing through them, damaged ducts can significantly reduce your HVAC system’s efficiency, which means higher energy bills. In some cases, the damage can be repaired. However, when ducts are beyond reparations, the prudent option is to have the ductwork replaced. 

Common signs that ductwork needs to be replaced include: 

If you are experiencing any of these issues, reach out to our professionals for an inspection of your ductwork. Once we evaluate the condition of your ducts, we’ll advise you on the best way to proceed. If you are getting ready to install a new AC or heating system, and your ductwork is older and deteriorating, now would be a great time to consider installing new ducts.  


Mold inside your HVAC units air ducts can be dangerous. People with asthma, younger children, or people weak immune systems may feel the impact more than others, so it is best to ensure you have regular ac maintenance. This will allow you to have a better indoor air quality and help keep your family safe from potential harm.
