Car air conditioner blowing white smoke

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. The odorless, white steam or smoke coming out of your air conditioner is probably excess water stored in the heater box. Commonly, it is a sign of a restricted drain hole that needs cleaning. The steam or vapor collected during the process of condensation could have made its way out when the air hit it.

Your expansion coils get quite col and any moisture in the air will start to condense as the air crosses the cold expansion coils. 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. 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.

The white smoke is water vapor. 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. The Drier removes moisture from inside the system.

Blue Smoke = Engine burning oil. The air temperature near the unit is below Dew Point, this. One reason for white smoke is very common and completely harmless. 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.

Why do air conditioners blow out white smoke ? If this is your first visit, be sure to check out the FAQ by clicking the link above. You may have to register before you can post: click the register link above to proceed. 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. The cold air mixing with warmer humid air is causing the moisture in the air to condense and look like smoke or fog.

The cold dryer air blowing out of the air conditioner is mixing with warmer humid air causing the water to condense in the air producing a light fog or appear as smoke to blow out. The burning smell and smoke may be be caused by a wiring fire or melting components. Call NOW, for same day service. The refrigeration process is a result of some components that work together to create the cooling effect inside a vehicle. Air conditioning does.

It sounds like your smoke was the refrigerant leaking out very rapidly. It has a sweetish smell. Its possible the low coolant and the smoke are related to a blown heater core. The heater core is basically a radiator, where the hot engine coolant runs through to heat the interior of the car. There is a fan which blows over the heater core and heats the interior air.

But, people generally face this issue. Even if you have recharged your AC , the issue in other car machinery can affect its working too. So, let’s find out why the car AC not blowing cold air after recharge. He said it is quite common for a car producing white smoke in morning because of internal combustion of remaining fuel in engine. And I should not worry about it.

If there is a problem of oil and coolant mixing then car will continuously produce white smoke. This kind of smoke disappears. And that gave me a sensible answer and relief.

I suggest those whoever get panic of white smoke should keep cheching their cars based on below points for a week- 1. On two occasions–the only two that I have used it–running the air conditioner has caused bluish smoke to come out of the engine. If I turn it off, the smoke slows and stops. The air conditioner works regardless, and the engine does not overheat when this happens.
