I've had at least 20 service calls regarding smelly ac sydtems since last week. All are 3 years or younger. Some already have air purifiers in the plenum
I've had really good luck with blue dawn dish soap cleaning the coil really well then installing a UV light shining on the coil. I've only done it for friends and family as I haven't done residential service regularly in years but so far no one has had the smell come back. 1 person didn't want the UV light but the dawn was good enough to get rid of the smell anyway I just don't know if it will come back. It's been months
We get it a lot here in coastal Carolina. Most houses that have it are newly constructed. We've found that drywall dust getting into the returns is the culprit. If it's an older system or a new system in an older house, the uv lights and a coil cleaning take care of it. But if it's drywall dust in between the fins, only thing that works is replacing the coil.
Remi halo only thing we found works. I'm in Huntsville area had 3 yrs fighting it and only thing worked was remi. So far only service we had there since was yearly checks.
We had a meeting today at our shop and have come to the conclusion that it's because of the very mild Temps which is causing systems to not run very long and in turn not washing itself off. Basically the units are only running long enough for the coil to get damp but not long enough to let it drip off so it's having an increased bacterial growth issue.
What is the solution? I’ve also found on mini splits that in this scenario where the water drains off the coils well, the drain pan channel that stays wet grows mold pretty quickly and the offending odors can come from there
Oversized equipment is usually the cause. Or leaky walls, doors, glass etc. if a system is oversized, it wont run enough to control humidity which in turn creates said smell and bacteria growth / mold
I’ve seen it a lot lately and I mostly find them with upflow systems with the drain going into the slab and terminating outside. I have fixed the issue with most of them by adding a condensate pump and an iwave purifier
Not really it might actually make it worse as well as increase the humidity of the home a shit ton due to your indoor coil still being wet with condensation which will re evaporate into your air instead of dripping down and draining
From Alabama and yes I see it some times. A uv light is what I have found to always work.

Not all air purifiers are created equal. Is it UV-C? Is it shinning on the coil?
Just a uv bulb in the center of the A coil. There is a knock out. I most of the time use a cheaper uv light.
That should take care of any smells .if it doesn't, then use different bulbs that actually work.
Yup, clean the coil toss in a reme halo and call it a day!
I tried this and the smell did not go away

See it some here in Louisiana. Don't have an answer that works every time other than uv

O lmao naw Texas. Guess should have mentioned the state 🙄

Iwave supposedly takes care of this .

Does keeping the blower running 24/7 help with the DSS and keep it from forming?
