omg what is that odor?
 
Got my new Trane AC installed today and the crew were polite, professional and cleaned my garage better than it was when they began.

I did notice a smell when they were working. Tonight when I looked into the return air I saw a big pile of a foam. I think its one of those spray things that harden.

Just turned the AC on for the first time and that odor is horrible and is permeating the house. I'm a bit sensitive to odors, so maybe it bothers me more than most.

I do read labels and know some materials with odors aren't healthy to breathe.

Will this smell go away. Is there anything I can do to help dissipate this odor?

Another question is that the old unit sat closer to the house. This is 12" away. That big gap means less space on the sidewalk, not that I use that side of the house. I wondered if they had to position the new unit there so that it matched up something or the other.

I figured they didn't like pesky homeowners following them around asking questions, so I didn't ask them when they were here.

thanks

The gap is so it can get enough air.

After the foam cures the odor will go away.

Not sure anyone could even guess why it had to be moved without a picture.
To locate it so it was behond the drip line of the hosue may be one reason.

thanks.

The odor is strong and close to my bedroom so I taped plastic over the grill and that helps to keep the odor away. But I can still smell it out in the living room.

It was irritating my sinuses. Glad I didn't remove the window unit yet.

BEENTHERE: approximately how many days will it take for the foam to cure?

Depends on how thick it is. Could take several days.

The AC Co. called the foam, "Mastik".

Today at 1 pm I can barely smell it.

Mastik is like duct sealer and yeah it stinks for a few days. Another reason for the 12" space is so they can remove the doors/louvers/covers to service it and clean the outdoor coil properly. AND especially with that unit the outdoor coil should be professionally cleaned once a year. Has a spine fin coil that looks like Xmas tree tinsel/garland and gets dirty very easy but is supposed to be more efficient than a regular fin coil.

yuri,

thanks. I tend to save money by skipping service calls, but I'll try to do this annually.

I think it was already posted, but I'm sure the reason for them moving your outdoor unit was to keep it away from the drip line (rain coming off the roof) Most installers do this if possible...if they can't, no big deal.
And for your odor, you say you turned on the A/C? So I'm assuming you turned on your cold air and not the heat. Some customers complain about the smell when turning on the heat for the first time when using a straight cooled unit (heat strips). The new heat strips tend to smell initially due to the oil's that are around the coils of the heater strips.
And the "mastik" or as we call it "pookie"... typically doesn't have much of an odor to it from what I recall... But most are water based products anyways, so you don't have anything to worry about.

thanks. It happened to be the AC I was using.

The AC owner came Friday to check the work. Couple of minor things he's having his guys re-do so it will pass inspection. Like some spots in the return air cubby hole need a bit more mastik.

He said the condenser has to be 12" from a house to meet code.

My roof line, or soffit, is exceptionally deep so it will still drip on the condenser.

Also, it's a good thing I had this work done now. The owner said the leak in the old air handler had rotted the wood that it sits on. They replaced the wood.
