Question about Heating & Cooling

Open Question

I have a Roadtrek class B rv and when it rains, i have water coming in the rv just underneath the AC unit. It appears that the AC is sitting inside a self contained box and it looks like it's only open to the rear. However, when i take the cover off from inside the rv, i can see that the water accumulates in the bottom........it should drain outside but it doesn't even when i'm at a small incline of maybe 3-4%, the back being lower than the front. Pls help. Tks

SOURCE: Water not draining out the back

Check the weep holes in the bottom of unit. It is holding water and when it does flood itself it will be inside with you.

SOURCE: rv ac unit leaks, even when fan only

Where the pipes enter the building, look carefully there for a bad seal. Use a good quality sealant and block the leak properly. If there is no rain, and the unit is leaking still with the fan on only, then you have an issue with the drain pipe angle or a kinked pipe or a blockage. Suggest you have it seen to by a aircon. technician as that repair is really not easy.(AC will possibly have to come out to rectify problem).

SOURCE: water dripping out of rv ac into rv.

Is it a ducted system? If yes, check that there isn't gaps between the divider that separates return air at the front, with forced(cold) air. You can usually use a flashlight and look for gaps, or even (very carefully) feel it blowing cold into the warm air return. If you find some gaps, buy some foil tape, and tape them off good and retry and see if it still happens. Some older units experienced cracks in drip trays that allowed condensation to drip inside as well. Get back to me with year of your RV, and whether it's ducted or non-ducted system, and perhaps I can guide you better on what to look for.

SOURCE: ac unit keeps reading fl

After reading over the Owner's Manual for your unit, I wonder if you are operating it in the Cool & Dry Mode. If that's the case, the dehumidifier is in operation, which would account for having to drain the unit every 2 to 3 hours. Ideally, the Cool and Dry Mode should only be operated for about an hour, when the unit is first started . Removing the humidity will allow the AC function to cool more effectively. But, it is not necessary for it to remain in Cool & Dry mode all the time. Because the AC itself unit will remove some humidity too.

Hope this helped you to troubleshoot and solve the issue of having to drain the unit every 2 to 3 hours

Multiple clicking sounds coming from AC unit before AC unit turns on or before furnace turns on.


the is a 24v wire that feeds from your thermostat to your unit, inside there is a contactor that engages, this makes a click sound as it really is a basic mechanical part the makes metal touch metal to allow current to flow through the system, perfectly normal, your hearing the low voltage engage the highvoltage at the contactor.

RV AC is working fine, but the water is leaking from the ceiling Where is the drain tube on the unit, The AC unit is a roof type, Duo Therm serial # 43404934, Part # 3105459


Normally, the condensate will drain out of the unit onto the roof and off the edge to the ground. Remove your cover inside (probably 2 screws) and tighten the 4 bolts you will find inside. If they are tight, go to your RV supply place and get new roof gasket. Remove the AC and insert the new gasket and resecure the AC to your roof.

Thanks for your question @ FixYa.com

Water coming from ceiling about 3 foot from unit


Does the unit work other, than the leaking?If it does you need to install a square seal between the ac unit and the roof.You can either buy the seal from Ebay or I would recomend an Rv Repair place.(They Might even be able to install it where the Rv Sits)

I own a 2004 Suzuki Forenza and have noticed that water drips on the carpet when I run the AC or when it rains. We've already taken apart the drain and confirmed that the leak is not from the drain under...


You are exactly correct. There is a drain on the bottom of the evaporator case. Probably need to place the car on ramps or jackstands to get underthere and clean it out. If you don't feel you can do that safely go to a machanic and tell him what you need done. The drain is on the passengers side down by the front floor. Most times it's out side in the engine compartment, but some have a small hose you can get to inside.

Pop up camper-leaking from ac unit when it rains.


Personally I would undo the 4 bolts that hold the upper unit (outside) to lower unit (inside) , then with circuit breaker off & confirmed that no power to it, take cover off for hydro connection, and unhook those wires, and unclip harness from connector to upper unit, to allow for removal of the lower & upper unit, then remove both upper & lower and cover the hole for now until you decide on whether or not your going to fix the roof supports in that area. I'd cut a 16" square piece of painted plywood or fairly stiff aluminum, add a good thick bead of sealant (not silicone, it doesn't last long) to the area where you see the gasket was seated & screw the cover right to the roof for a temporary fix. Make sure you attach screws close to where gasket would be under your cover, (about 1"-1-1/2" in from edge of 16" cover) so that the holes will be covered later when AC unit put back on, by the gasket of the AC unit. Make sure you put maretts back on hydro wires & add some electrical tape over them as well to keep maretts on while traveling for now. Don't know how handy you are, but fixing that over the winter may not be as bad as you think. If you need advice later, get back to me/us.
