I already sent in a question Order # 29744. Our window air conditioner Frigididaire Gallery blows out black particles about 1/8-1/4 inch in size. What is it? Is it dangerous? Please answer immediately. ...

Probably, what you're seeing is rust from the drain pan under the unit, that has become dislodged and is being picked up by the AC unit's fan or it could be the air intake filter breaking down and being blown in the house. Have you removed and inspected the air intake filter for dirt or clogs or deterioration ?

These are the things you need to inspect and troubleshoot first, to determine where they are coming from. If the unit is continuing to cool, as it should, I suspect that what I mentioned above may be the cause of the particles.

If it's the air intake filter replace it. If the particles appear to be rusty or slick, try flushing the drain pan under the outside of the unit. Be sure the outside of the unit is tiled down at least 1/4". Or it will not drain properly.

Is this a dangerous situation? I don't feel comfortable saying "Yes" or "No". But, it has to be a messy one. Be sure to turn the Master ON/OFF Switch to OFF and unplug the unit, before attempting to troubleshoot anything.

Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks

The unit frosts and freezes up after only a few minutes of running...why???

Common causes of this problem are:

1., Dirty or clogged air intake filter.

2. The humidity level outside is extremely high.

3. The compressor is low on refrigerant gas and needs to be recharged.

4. The cooling coils are dirty and need to be cleaned, as do the fins

5. Defrost sensor has failed and needs to be replaced.

Allow the unit to completely thaw and unplug it, before attempting any of the above service work.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

I have a Haier Commercial Cool air conditioner, model CPRD12XC7, 12,000 BTU that has 2 hoses off the back and is made to be vented thru a window. I want to install it in a closet with no windows. Can I...

Mark, the two hoses serve different functions (Fresh Air Intake & Hot Air Exhaust). Therefore, they would have to remain separate. Also, Haier does not recommend extending the length of the hoses, to accommodate a specific change in installation. And yes, they can be vented through a wall to the outside. But, you would need to use something similar to a clothes dryer vent termination on the outside. Most exterior dryer vent terminations have insect screening and a flap door that opens when air from the dryer pushes it open. This would be fine for the exhaust hose, but not the Air Intake Hose. I guess if you could carefully remove the flap door. it could be used on the Air Intake hose. Also, keep in mind that the unit requires a minimum of one foot air space clearance off the back of the unit, for proper air circulation around the unit. If clothes will be hanging in this closet, that may present an air circulation issue.

Hope this helped you, please let me know. Thanks.

I have a danby portable air conditioner with no manual. The picture shows two ducts going outside. My question is why does the intake go outside?

On a portable a/c unit the cooling is done by taking heat out of the air inside and dispensing it outside.

That's accomplished by washing air over the heat coil in the unit, then the air goes back outside to let the heat out there.

You'll need inlet air, and outlet air to accomplish that.

Inlet air is cooler as it comes in, then that air absorbs some of the heat inside the space you're cooling and turns around to go back out leaching heat outside.

Most likely scenario.

There may be another need for outside air revolving around positive pressure inside the conditioned space.

Let me know if that doesn't solve your situ.

Air intake via hose & window or intake from room only?

Hello artrey3 The answer is yes, BUT the unit will be exausting room/basement air outside ruining any efficency the unit is rated for.Also you will need makeup/fresh air in the basement. The unit exausting air can put the basement in a vacuum/negitive pressure pulling in air from the chimney!

Our room air conditioner keeps dripping water when it is running, what can we do?

Most window air conditioners require a slight til downward while in the window to allow the water to run to the back and rain outside. Try that and if that does not help unplug and slide the AC out of the cabinet there is a drain at the bottom of the evaporator. Try cleaning it out so water will flow freely outside.

Chemicals in house from pool when running air conditioner

There is a small possibility that the air conditioner is sucking some of the air outside. If you're using a window type a/c, there is a small fresh air intake vent you can open and close. If your using a wall type or free standing a/c, fresh air would only come from opening doors or windows. Using a centralized a/c has a fresh air intake and that could be the cause of your problem. The solution would be an anti-odor filter.

I hope this helps.

the slope is downwards to furnace.The slope isnt for the moisture it is a rise for the flue gas to go outside.The intake is usually connected to the furnace to use outside air for the combustion but it does not have to be.if it isnt an option to take the pipe apart to glue it all up you can seal the water leaks with silicon.anymore questions
