White smoke coming out of ac vent

Air Conditioners Fog Or Smoke Coming Out Air Vents Fog or smoke coming out the air vents is caused by cold dry air coming in contact with warmer, more moist air near the air conditioner. If the air temperature near the unit is below the dew point, this causes water vapor to form in the air and condense into water droplets, thus causing the fog or smoke. This is the second time this has happened.

I just hope its not a freon leak or something. One is the evaporator core has sprung a large leak, and the smell is from the refrigerant oil, and the fog is the refrigerant. At that point, the evaporator core needs to be replaced. When one of the resistors goes, white smoke is fed dirrectly up to the vents. Replacement is easy (admittedly while doing a head stand in the passenger footwell) and fairly cheap.

Suggestion: many other cars will have a similar layout. A visible stream of constant smoke tells you that the source is very near the blower or the air intake , or is inside the duct itself.

It started raining heavily for a little over minutes, and then the rain stopped.

Suddenly, what appeared to be whitish smoke started coming out of the center vents. When the core freezes, it can cause the air out of the vents to get warm because the air going threw the hvac box can not get threw the core any more and it makes its way past the heater core instead. There is a temp sensor on the evaporator core that should turn the compressor off when its around 35deg.

If there’s a small pinhole — which is a small leak typically caused by corrosion — in the heater core, drivers may have steam coming from the vents, but it will likely smell of coolant. Coolant may also drip on the passenger side floor. U can also smell exhaust smoke in traffic. You air vent is not closing properly and too much of outside air is mixing with your cold air, or your aircon coil is really dirty and lots of water condensation in you aircon system. A fine mist coming from the.

Recently, when turning on the AC , it appears that white smoke is blowing out of the vents. AC blows what looks like white smoke. It does not smell like smoke or fill the interior up with this cloudy substance.

The AC still gets cold. There are a few possible causes for this though. Your furnace’s heat exchanger may be cracke which is what’s allowing the soot to escape into your home’s air vents. A cracked heat exchanger means that not only is your furnace spreading soot around your home but poisonous exhaust fumes, too.

If the heat exchanger is cracke it’ll need replacing. Hey guys, so this has been happening for days in a row now and randomly when im driving or pulling hard smoke starts coming out of my front two air vents. It smells like an electrical smoke or something.

I have a 420a motor and the turbo is not yet installed the engine is mostly stock except for a cold air intake. Thread: Smoke coming out of vents. Refer to the following TSB.
