I have an older a/c in my window in my bedroom, the past two days its been extremely humid outside and i have noticed white air or steam coming out of the vent? It seems to be running fine, its been used ALOT. Is this a problem? I have kept it clean, cleaned the filter, its venting properly outside. Is it the humidity?

Smoke or frost? More than likely frost make sure the air filter is clean and evaporator coil is clean this is a sign of low air flow across evap coil or turn fan speed up.

Due to high humidity and perhaps, an air intake filter that needs to be removed and cleaned. That "steam" is actually a misty fog and is harmless. Window & Thru the Wall AC units often do this when the outside humidity and temperatures are high. Keeping the air intake filter clean will help to lessen this mist.

Hope this helped to allay your concern. Thanks fo choosing FixYa.

If it is hot and humid when you run the dryer, then the exhaust tube has come loose from the back of the dryer, or you have a hole in the vent hose. Basically what is happening is the moist air that is supposed to travel outside is backing up into your house. No cause for alarm right now since the steam is harmless, But over time, the hummidity might cause a mold problem if it not addressed. I'm looking for answers on loud dryers so I cant answer your second part, but I'll bet its a belt issue.

AC vent to close to your dryer. This is usually because your house ac is cooling the caseing of your dryer down and outside air is creeping back in thru your exhaust on your dryer. Make sure the vents are closing on the exhaust dryer air and that there is not a vent close by that is helping your dryer shell to chill. I have only seen this 3 times but it is a problem. you will notice the water after drying a load and removing it after a hour or so you open the door and there will be water. This happens only in extreme heat and usually hi humidity outside.

This is caused by high humidity and difference in temperature from inside to outside. So in winter when you have the heater on, there is a reaction when the inside of the upvc is heated and the outside is cooled and causes condensation to build up. Very similar to when you are in a car and there is humid cold weather. The black spots are very possibly a fungus growing as a result of the high humidity. You need to introduce fresh air into the house possible with a small inlet fan.

I replaced the control board and it works now.

If the fridge is working and keeping things cold and frozen, you don't have a refridgerant leak that is producing vapor that might appear as steam or smoke.

The steam/smoke is actually water vapor being made visable due to the temperature difference between the freezer/fridge temperatures and the air temp in the room (or garage) the appliance is in.

It's nothing to worry about and is normally more likely to happen when the outside or house air temp is very warm (Summer months) and when the air is humid.

What's happening is the very cold and cool air is hitting and mixing with the much warmer and much more dense air (humid air contains microscopic water particles) when you open the doors, and is instantly being cooled. Thus it appears as thou the fridge is steaming or smoking.

Have a great day an hope this explains the situation. Best regards.

I would consider replacing the t'stat if it does not seem to cycle at the desired temps. Also, the outside air allows fresh air to be introduced into the conditioned space but it will also effect, to a degree, the units ability to cool the conditioned space. Once you get the unit running, try it with the baffle on and closed and see which one you like. Remember, the outside air has and add humidity and can make it seem hotter than it really is in the room.

If the humidity is low then the amount of water removed will be low. The AC (I assume is a window unit) May be evaporating it off as soon as its drained outside..

Yes in low temps and humidity it is normal for no moisture to be made in abundance.

This is all assuming the temp is coming down as you direct it to.

Please rate me as high as you can and thank you for using fix ya.

The most probable reason that the humidifier does not reach the levels you describe is because you said you had the unit in your bedroom.

Bedrooms typically contain materials that are known as "hygroscopic." What that means in plain English is that items such as the bedding, mattress, any carpeting, wood, curtains, you, etc. all absorb moisture , kinda like a sponge. Since that moisture is being held by these materials, the air itself contains less by percentage. 25-30% humidity is actually pretty good for any room, especially in colder climates and higher humidity levels can lead to the production of mold, condensation on windows, etc., which are not good things. The good news is that reasonable humidity levels are healthier for textiles such as carpeting, cloth, and so on because the fibers won't dry out and crack. Dust is also reduced, but again, only to a certain level.

If your humidifier is reaching 30% it's probably working ok.
