Ok im living in a older prowler 5er right now for school and my dad told me to clean the coils on the ac from inside the trailer. So my question is do i clean the coils from inside the trailer or should i get on the roof and do it?

 

Do you know what type of roof you have?

 

not sure

 

Some roofs are not strong enough to support adult weight. May need to use a couple of boards to help distribute the weight.

 

well my dad told me that a rv guy said to clean em from the inside but i pulled the cover and i just dont see how to do it.

 

You may need to remove the hood from the unit from on top of the roof.. Never heard of cleaning them from inside the camper? I could be wrong though

 

Thats what i was thinking that i needed to remove the hood on the roof. I can some what see the coils and feel them from the inside but there is sheet metal and wires that are there and i dont really wanna spray this coil clean and then water to clean it.

 

You do it from the roof. Most RVs will suppord the weight of an average adult. Remove the filter inside, and put a bucket under it. Go on the roof & remove the plastic cover. Next remove the sheet metal shroud/cover over the coils. You will see both coils then. You can clean them with a toilet brush or simular. The rear coil will drain outside when water is splashed thru for rinsing. The front coil will drain into the cabin. Make sure you have the bucket under the coils. Not too hard of a job, and can make a difference in AC performance.

 

Thanks yall

Now what kinda of weight do yall think the roof will hold. You say avg adult do yall think it would hold me being around 6'4" and 245#?

 

lay a piece of plywood up on the roof where you'll be walking and standing and you should be ok. Most rv roofs are 1X2's about 24" apart with some 1/4" luan plywood stapled on as a deck. I have been on roofs without extra support but you can feel that it's thin under there. A scrap of plywood will disperse your weight out further and be ok.

 

Thanks again yall i will try it when i get out of class/lab today

 

Remember too, DO NOT over tighten the 4 mounting screws on the inside of the ac unit. As long as the unit is not leaking water from the outside, leave them alone. Most people see that they are not too tight and crank them down. This will destroy the thick foam gasket and cause a leak.

If your just cleaning the coils, you shouldn't even need to mess with them. So this is just a simple FYI

 

I clean my coils from inside the unit. Be sure to cover the floor with visqueen first. Also, make sure the condensate drain is open. Works great - - don't even get on the roof. Pull the filter, cover the floor, spray the coils with cleaner, let it sit, then CAREFULLY rinse the coils using a small jet sprayer on your hose. You will get a little overspray back at you and on the floor. Do not use copious amounts of water too quickly - - keep looking into the pan to make sure it is draining and not filling up.

condensate drain what is this and where might it be?

I know that i probly need to turn the a/c of but should i unplug the trailer also before i do this and also im guessing i should allow it time to dry before i turn it back on correct?

 

usually not a condensate drain. It runs out of the outer unit on top. Thats why folks are always trying ti tilt thier rigs diffrent directions to control the path of the drip.


Hint===toss a length of cotton rope over and around the roof unit. Pull both ends towards the side you want it to drip on. The cotton rope will act as a dam and direct the condensation to where YOU want it to go.
