Air Duct Cleaning - Is It Worth the Investment?

Hello everyone,

I've been hearing a lot about air duct cleaning lately, and I'm wondering if it's something I should invest in for my home. I know it can improve air quality, but I'm curious to know if anyone has had a noticeable difference in their home's air quality or energy efficiency after having it done.

Some specific questions I have:

• How do I know if my air ducts really need cleaning?

• Are there any particular signs that indicate it's time to clean them?

• How much does it typically cost, and is it worth the investment?

• Does it make a noticeable difference in reducing dust, allergens, or odors?

• Should I hire a professional, or can this be done as a DIY project?

Would love to hear your experiences and insights! Thanks in advance!
