Just had a new heat exchanger put in our furnace. We also had a new coil put in for the Ac at the beginning of the summer (it had grown bacteria, and smelled awful when the AC was running). We had a very warm day today, and we turned on the AC (first time since the new heat ex. was put in). The air from the AC wreaks!! The tech said he was using silicone, etc. to put in the heat exchanger. It smelled for awhile when the heat was running, but went away. But the heat doesn't smell. Just the AC. Again, we turned it on because it's extraordinarily warm, almost 80 in the house. We are not happy. We just replaced the coil for the AC! Could the installer have gotten some chemical on our new coil when he was installing the heat exchanger? He said he's only worked for the Co. a short time. Any advice? I refuse to pay for a new coil AGAIN, if they state that's the issue. Sure smells like it. Thanks.
I'm not sure of anything that would just make the A/C smell. Even if the tech was using silicone, it shouldn't leave a smell that long.... Might stink for a little bit but not that long. I'm not sure of any chemicals he could have gotten on the coil that would make it stink.. Even if he just cleaned it, and used a coil cleaner(which said before would leave a smell) it should stink that long. I would contact the company and tell them, your problems, ya never know it might be some stupid little mistake that the tech made while installing it. Good Luck.
It doesn't matter heat or cooling the blower fan is still blowing Thru the same unit. The cooling coil and heat exchanger is in line with each other, it's the same air blowing thru the unit. What I'm trying to say is that you should smell the same smell while cooling or heating. Vinny
Too many stuff smell funky yet some issues it incredibly is are mould on the A frames interior the blower from water placing in it throughout the iciness or a plugged drain pan. some thing might are starting to be into the duct paintings and is rotting. in the journey that your duct paintings is below your place and animals can get to it you have a nest interior the duct. There might desire to be some thing on the threshold of the intake vent it incredibly is giving off a smell which you cant smell on the intake.
Other remedies: Replace filters Clean inside ductwok yourself or hire contractors. Ensure humidifier in ductwork is clean
don't know of anything that they would have used,i've installed several hundred and never used anything,are you sure its new and not just been cleaned with coil cleaner? now that leaves a smell
