Most of them are scams.

Here is a really detailed explanation of what to look for and when duct cleaning is recommended. Spoiler: almost never.

A few other links for your perusal, the first also gives the short answer to if duct cleaning is worthwhile

quote:

---

Generally, duct cleaning is not worth the money except for a few rare and extenuating circumstances, such as:

Substantial mold is visibly growing in your ducts
Vermin or rodents have infested your vents
Ducts are clogged to the point that debris and dust particles are being released into your home

As I stated in the other thread on ducts, was able to visually inspect the inside of my 30 year old rigid ducts with a HVAC changeout last year including a new air supply plenum, and the insides were pristine.

If you I wouldn’t clean them unless it was warranted. If your wife is insistent on spending $ on HVAC to improve IAQ install a Reme Halo or comparable.

It depends on a few things. Do you have flex or rigid ducts? Have you done any major construction with lots of dust lately? Do you have floor or ceiling registers? How often do you change your filter?

we just purchased the house on jan 1 and did hella construction.

we have a massive intake (24x36) which i replaced on the wall and swapped filters like crazy during construction.

however, we don't know anything from the period: 1978-Dec 2023

a long time for ducts to exist in an unknown state.

My downstairs ducts are on the floor (older house) and we bought the house from an old couple that were nasty cat people and had lived there for 30 years. I also don't think they used the HVAC much to save money. I had them cleaned and he showed me what came out and I was fricking mortified. A couple petrified mice, more than enough cat hair to fill a 30 gallon garbage can, etc.

That said, outside of a situation like that, I don't think you need to do it much, if ever, if you are a clean person, run your system fairly consistently, and change your filters.

ETA:

I knew the hair was a problem because when I cranked on the AC it shot up in a clump onto the duct vent grate and stuck there, then fell back down when the air shut off

I think their cats liked to lay on the vents. I know my dogs do in the Summer

Just a theory.

I also had to rip out part of the sub floor in a guest room because of the largest concentration of cat urine in the Northern Hemisphere. And that shite doesn't just go away.

I paid some jabroneys to clean my ductwork a couple of years back. They got a ton of shite out of them. However, I couldn’t tell any difference in air quality after I had it done. I won’t be doing this again.
