3 ton goodman heat pump package unit, odor coming from vents

We installed a new unit last year, this is our second winter season and although it works fine, about every 45 minutes to an hour we smell a chemical-like smell blowing through the vents while the unit is running. It just started a couple of weeks ago and we can't figure out what is causing it. There are no signs of any leaks, but how do you know for sure? I'm worried we might get sick from it, I have never smelled this before, it smells almost like baking soda or the inside of a cooler. Thank you for any suggestions.

    I'm having the same problem. Goodman dual fuel unit installed last year . . . worked fine. This season, I'm getting a pungent odor inside the house through the vents. I turned off the humidifier thinking that might be the cause, but the odor continues. Odor seems to prevail during the cycle when cooler air is coming through, rather than warm air.

    I have the same problem but with my Goodman GPG13 13 Seer 3Ton Gas/Electric unit. The smell starts when the heater come on and blows throughout the house but concentrates in the rooms in the highest level of our home. The smell is not carbon monoxide or gas. It disappears when we turn the unit to 76 degrees or higher but is alway there when it is on the normal 70-72 degree settings. Causes itchy, watery eyes, sore throat and conjestion. Our next step is to bring in an air quality inspector to determine what the smells is since the installer/service company can't figure this out. If things don't get better we are going to need to remove the unite.

    We have a Trane 4 ton unit installed last year and have the same problem. It doesn't have any pattern so when the repair guy shows up to make it do it. The smell makes the whole house stink. Smells like dirty socks or something. It was a new unit with new duct work. This is the second winter that this has happened. Any thoughts what it could be ?

    We have the same problem. Weird "cooler" smell every 1/ 2 hour or so that gives me a sore throat. This happens whether the air conditioning is running or the heat is running. When we turn the heat pump off and just the emergency heat (just the furnace) is running -- there is no smell.

    I have the same issue. I have a small townhome with a Goodman heater. On some days,I can smell the odor from every part of the house. I've had ducts cleaned, gotten rid of carpet in part of basement, and have air purifiers running constantly in the house. It still doesn't seem to help the issue and I'm getting a scratchy, sore throat after being in the house a while.

    We had a 4 ton American Standard installed in 2007. When a/c is running, strong chemical smell emits thru the vents, like paint or glue or something along those lines. We are getting metallic taste in our mouths also when it's running. No odor when heat is on, just a/c. Installer came out once and found a white powdery substance inside the unit, refused to tell us what it was. Unit was cleaned out and seemed ok. Next season, odor returned. Installer refused to come out again, saying unit is just fine and the smell is due to our cats.

  • Brenda Venable Jan 30, 2013

    I AM ALSO HAVING this problem. Just had my old system replaced inside the attic (Houston Texas) and now I suddenly have this horrible chemical smell). Paid the A/c company another $65.00 to say they don't smell it..ugh. I make me feel sick. Does anyone know anything else about this new aluminum?

I ran upon this a few years agoafter 20+ years in the industry it is actually called "DIRTY SOCK". In the winter the drain pan and trap dry out and all the junk left behind when the summer rolls around mix with the condensateand cause the odor. "Home owner fix" pour a cup of bleach down the drain and in the pan let sit for about an hour then pour a gallon of hot water, that usually takes care of it.

Sounds like there may be mold growing in the evaporator drain pan and when the furnace comes on the its being burned off. I would get a UV light and have it installed in the return air and also have the coils cleaned up and the drain pan cleaned.

    I agree, that sounds like it could definitely be a mold problem. I would have a mechanic take a look at your air conditioner asap to make sure that whatever odor that is coming out isn't poisonous. You probably shouldn't use the machine until you are sure that it is working properly. http://thatservicecompany.com

The name "Dirty Sock Syndrome" has been used to cover up a major problem with the HVAC industry. The mold/mildew/bacteria smell was what originally came up with the name, but this latest smell isn't the same. It's the result of the new kind of aluminum that's being used in the units. As far as the ordinary installer would know, it's the same material. It looks the same, it bends easily just like the old stuff. But, it's a new formula of aluminum that has been used and sheds the oxidization much more often than the old formula. The white powder that will generally be found all over the floor and sides of the indoor air fan compartment is evidence of the new troubles. Eventually, somebody will do a study of this stuff and find out if it's dangerous or not. If lawyers get involved first, you can bet it's going to be called dangerous...

5 ton goodman package unit not coming on


If you look on the install manual. It says it will work for a heat pump without backup heat. No heat strips.........If you do not have strips the guide says as follows

"PLACE A JUMPER (PIECE OF WIRE) BETWEEN Y AND W IF YOU ARE USING A HEAT PUMP WITHOUT AUXILIARY/BACKUP HEAT." if this dosnt work check the fuse in the air handler you may have blown it if you did not turn the unit off before installing.

Ac unit keeps freezing up


what a heat pump is designed to do is reverse the evaporator inside coil and condensor outside coil. it trys to pick up heat from outside and transfer it inside. they work fairly well down to about 40 degrees ambient then not so good. that is why you have auxillary heat i.e. 15 kw. when it was shaking as you saw the compressor is trying to pump liquid instad of vapor as it's designed to. you either have a control issue or it's overcharged.

Will not come on but emergence heat works


Check contactor that operates compressor and condenser fan. Does it try to come on when you first turn it on, or just sits there? If it tries to come on, it could be the capacitor.

Goodman package unit heat strips will not turn on


Put meter probes at in put terminal of the element if you read 220volts that mean your relay is good. if you got it there use amp meter on one leg of that element. You should read some amp draw there but if there is no amp draw it mean the element broke.

Fan not running on Heat Pum


That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up!
The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.
