Default Home AC Stinks

We just fired up our ac unit for the first time this year. And it stinks, the duct work isn't that old maybe 5 years?

Any thoughts.

It's most likely the coil on the FCU. I buy mine at Grainger but I'm sure you can get it at any supply store. (I'll leave out the joke here) I've only needed to use it on 3 units out of 13 in 18 years. I get the no rinse spray can stuff. I'm not sure what causes it but it's moldy smelling in my case. You may as well take the time and dump some bleach in the drain to kill the ugly stuff that can grow in there. That is part of the PM program I use. Just be sure to have nothing but clean water in there before you dump it in.

You could also use a citus based cleaner or Simple Green but I prefered to get the proper cleaner for the job.

Default More info

This is the unit on the first floor. Heat and AC flow through the same duct. Ac/heat unit is one year old. Duct work is 5-6 years old. I believe the duct is wrapped but I need to go under house to look at it.
Unit is a York package unit? has a gas heat pack with ac.

Filters are new and are changed every 30 days. It is a weird smell not moldy but almost metalic. I can't put my finger on what the smell is, but is there.

I am going to look into the coil cleaner. Any other thoughts other then having the duct work redone

What does it smell like? Maybe you had a rat or mouse die in the system somewhere.

That is what I was thinking, or mold. Does it smell musty?

They won't help with diy but they will help you be more informed.

make sure the condensate is draining properly. Most often when I find stinky AC it's because the condensate can drain, it sits in the pans and gets funky.

If that unit is only a year old, I'd be inclined to call the company that installed it and have them check it out. Even if it's slightly beyond warranty, they may do a check as a PR measure. The best advertising is word of mouth from a happy customer.

Is the ductwork steel or fiberglass ductboard? Crawlspace, right?

Many of the previous posts make good points, especially the possible FREE PROFESSIONAL check. Doesn't hurt to have the system checked by an expert anyway. You might want to try the system in the off position at the thermostat and turn the fan from "auto" to "on" and see if you still get the smell.

I wonder what a ozonator would do if one stuck it in front of an air intake vent while the system was on? I know in a car it will clean the smell up with either the heat or A/C turned on.

The duct is fiberglass in the crawlspace. I will get the guy who installed it to look at it. Probably a dirty coil, I am going to go under the house this weekend and inspect the duct work.

Thanks for the input!

Is the fan operating smoothly? I once found a dead mouse inside the fan of a unit. Had been there for a while and it stuck BAD! The fan was the squirrel cage type and poor little guy was all wrapped in between the blades! I remember the homeowner saying "Huh, looks like he got quite the workout!"

It just amazes me on how bad a dead mouse can smell.
