Ac blowing out white smoke

Commonly, it is a sign of a restricted drain hole that needs cleaning. 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.

Probably because AC system is pumping heat not cold now. You usually always replace the Drier when any AC system will be opened to the air (even home units), i. Your expansion coils get quite col and any moisture in the air will start to condense as the air crosses the cold expansion coils. AC blows what looks like white smoke Recently, when turning on the AC , it appears that white smoke is blowing out of the vents. It does not smell like smoke or fill the interior up with this cloudy substance.

A faint whiff and occasional wisp of oil smoke with the AC blower on low will generally indicate a minor oil leak in the engine compartment. Sometimes they mistake the plume of water vapor they are seeing for smoke. Some even thinking their outdoor fan motor burned-up, because when this is happening the fan actually stops running even though the compressor continues running, sometimes making a louder than normal sound. The AC still gets cold.

One of two conditions is responsible for white smoke blowing out of your exhaust. First is normal condition (so you don’t have to panic) and the second is a not so normal condition which should be fixed as soon as possible. If you the white smoke consistently comes out and the sweet odor smell is present, then it is definitely a problem with your coolant leaking.

One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant, it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust.

What you are seeing is probably fog which is a large amount of water in the evap box. Some times the evaporator freezes up due to a lack of air flow or a restriction in the flow of freon in the system. This is a normal occurrence when certain conditions are met. I was driving to work today and smoke just started coming out of my air vents, I had the AC running, and it was running fiine. 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.

I lasted for about seconds and then stopped. It is my first day driving this vehicle and it happened all times I turned on the AC. Strangely it was not coming out of all vents, just the center right dash vent. Re: Why do air conditioners blow out white smoke ? High humidity and low fan speed.

This happens often with Vehicle air-conditioners when the conditions outside are warm but wet and miserable. A puff of white smoke came out near the compressor. It blew hot air during the smoke but i went home and when i left i tried it and have cold air. I just dont want all of the freon i put in to leak out.

Last time I broke rings and the ring lands, but the piston was in one piece. If your car is blowing alot of white smoke, it could be your car is burning too much fuel without enough air. BUT… If you smell a sweet smell, it means your head gasket is gone, and anti-freeze is leaking into your exuast manifold. It sounds like your smoke was the refrigerant leaking out very rapidly.

It has a sweetish smell. Do this: Run your furnace for about minutes and keep some windows open to let your home air out. If the smoke continues after minutes, contact a furnace technician for help.

Soot smell means there’s a big problem. Do you have an older furnace? Does the smoke smell like soot? If so, you have a serious problem that needs fixing. There are a few possible causes for this though.

Otherwise the air coming out would be foggy and the ducts would be soaking wet. So I wonder if this is a dryer issue.
