I would spray it with a clorox/water solution and then wipe it down with a rag wrapped around a knife... It is time consuming but gives the beat results...

Idling rough at stops

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Getting years and years out of your Window Air Cond.Unit.

The filter in the front if your unit is the life of the unit.You should check no less than once a week.Clean it under low warm running water w/soft towel.Then w/soft dry towel wipe dry gently- so not to tear the filter.If it doesn't look dirty,it still is a little,you can just wipe it down then,Before you put filter back(of course make sure unit is (OFF)Then do this: You can use a multi~surface cleaner like 409,spray a clean towel sprayed w/cleaner until it is very damp,then you're going to clean the coils Carefully;Slowly & gently follow the pattern of the coils(aluminum panel in the front same size as your filter)There should be some black on your towel & a noticeable difference in the shine of the coil panel.Once you're done w/entire panel,rinse towel clean while still damp.respray w/cleaner then to the left & one to the right you'll see what looks like copper tubes.One longw/ horseshoe shaped others running sideways ontop of the big one.Get in there &wipe all of it,top,bottom sides,as far back as uou can ''EASILY"reach,then do the same on other side.Also,In the winter cover the outside of the unit from the weather.In the summer (again unit OFF) you can spray w/a water hose the outtermost section of unit,removing leaves,debris,etc.Do checkups of unit in front (inside, part you move to control which way to blow air)for mold.Use quetips to clean around area.If you do this on a regular basis not only will your window unit stay clean and look much nicer but the unit will last years after its average est.time to replace.

Think theres mildow or mold in unit from last year, how can i clean unit out

First, pull-out your a/c unit. Open the electrical control and remove the wiring connections of your fan motor and the compressor. Separate the electrical control and make sure you have the wiring diagram for termination. Unscrew all panels to remove the fan motor, blower, and fan blade from the unit base. You have to move the evaporator farther but be careful with the pipes. After removing the panels, fan motor, fan, and blower wash the coils with water using pressurized water. Spray coil cleaner to remove excess dirt from the coils and wait until all dirt come out. make sure the chemical is not too strong to eat the aluminum fins. Wash and rinse thoroughly the coils to remove any chemicals left in the unit.Clean the panels, fan, blower, and motor.Oil bush type motor.Then assemble fixing the panels, blower, motor, fan blade panel, and fan blade. Screw all parts and rewire the unit.

Black particles coming out of the room air conditioner

dirt, dust, or mold. could also be the tubing insulation flaking off. either way, open it up and clean it out. the dirt, dust, and flaking insulation can restrict air flow through the coils and cause the ac to not function properly. if it is mold, it's can cause sickness (legionaire's disease). do not use chemicals on the coils. it might be best to replace the ac alltogether. to prevent mold: when installing the ac, make sure the unit is slightly tipped towards the outside. any condensation that collects on the coils will drain out. failure to do so will result in water pooling inside, and this can cause mold.

My duo therm ducted ac not blowing cold air...has a flaky crusty black stuff on the inside coils of return air side?

you need to clean this section of coils badly. Get a plant or weed sprayer. go to a a/c parts supply store and get some coil cleaner. Tell the staff that you need something to clean the coils on your a/c coil. Tell them what kind of a/c you have abd they will assist you in the purchase of the proper chemicals. Make sure to read directions for the use of the chemical and also wear all necessary protection equipment, i.e. safety glasses, gloves. Follow the instructions on the chemical as how to clean your coils. Once the coils are cleaned you still may need to have the pressures checked on your unit. It won't help to check the pressures on your unit when coils are dirty since that will give you false readings. So you need to start by cleaning the coils. Good luck Dave

I have a heat pump AC unit. Amana ASZ140241 SEER 14. The AC is not working; no cold air is blowing. I checked the unit outside and there is a block of ice around the pipe leading into the house. Is there...

The ice shows that you have freon so that to me is an indicator of an inside problem. Could be dirty air filter. Dirty a-coil, or bad blower motor.
I may need a little freon but do the cleaning yourself before you call anyone. It don't take an HVAC guy to wash coils. Use a foaming coil cleaner that is specifically for indoor use and go by the directions. The no rinse formula will draw out the coils and open the drain.

Clogged emmission

well you could say that almost every part of the engine is part of the emissions system, but in the main in the trade we mean the breather pipes and the air intake system, if the motor has high mileage it could be that its burning a little oil and could have clogged the catalytic converter if you put some upper cylinder cleaner in to the air intake following the instructions on the can it could clean it out for you the chemical is not that expensive and its not that hard a job to do. if you still have a problem you will need to look at checking that none of the little pipes are blocked if they are just blow them out or use some carburettor cleaner to clean them out (off the car) and blow them dry.
hope this helps JR

My coleman 3 ton heat pump blows very little air

Check the blower capacitor and blower speed, you probably have a 3 or 4 speed motor make sure it's on medium high or high speed.
If these are ok then shut the power off to the indoor unit and pull the blower housing out so you can see the blower wheel, make sure it's clean and very carefully spin the wheel to see if it spins freely keep hands away from wheel while it's spinning, if it doesn't then the bearings are bad and you need to replace the motor.
