Isn't cooling now that i've fixed leak

My roof top a/c was leaking inside my rv and i found that the drain holes were plugged up. i cleaned them up then my a/c started whistling real loud and now it blows warm air. when its set on low on thermostat it rattles and whines but high speed is almost normal except for warm air, the a/c did run cold until then.

The repairman that unclogged the drain holes tore off the insulation and didn't put it back on,so the a/c ran hot from then on and the noise was amphilied(sp) without it. i went up and opened it up and put some of that silver sheet insulation on it ,put it back together and wa-la it ran cold and quiet. needless to say i won't have that repairman back.i guess common sense was the cure. thank you anyway.

You won the battle, but lost the war, you need a full service, like cleanning both coils (front back coils , wash fan blades Front--back) clean filter( or change,) oil fan motor, check wirings,and connections for tightness, and last check charge. If the compressor don't start then add a hard-start-kit $10:00!

Why rv ac condensate leaks into rv


Drain holes on underside of unit on roof are probably plugged. Need to get up and look under and use a stick or similar to unplug drain holes. Should have condensation running across roof , if not, the drain holes are plugged. If worse comes to worse, may have to remove cover, only takes a minute, just be sure to shut power off prior.

I have a jayco pop up camper with a Duo-Therm BriskAir roof top a/c. im having problem with it leaking water inside of the camper? Is there a drain hose? Or wat do u think is wrong?Thanks


Yes there are drain holes in base of upper unit (on roof), which may be plugged. Couple of questions though to see if we can better troubleshoot this for you.
-Do you remember seeing water (condensation) running off roof before when AC was used?
-Have you cleaned filter inside at ceiling lately?

I have a travel trailer with a coleman 7300 roof top ac unit. the unit will blow cold air but water leaks thru the plenum. i was told by the previous owner that it needs a new seal. i would like to fix it...


If it's leaking inside where filter cover is, then real good chance the drains being plugged is the only problem. If water (condensation) not running off roof when operating in cool mode, then I'd bet drains, which are located under unit on roof, and you should see them sticking down like buttons. They have a hole in side that needs cleaning with a pipe cleaner or similar to open them up. If need be, shut off power to unit and remove top cover on roof unit and look for the drain holes in base, and clean them out. If water comes in while raining, but AC not running, then it's gasket. That is remedied by removing ceiling assembly (just screws) and 4 bolts that pull/hold the upper and lower assemblies together, unplug wiring to upper unit, and simply lift it off, change gasket and re-install. Tighten those 4 bolts equally when gasket is aligned properly over hole, only until gasket is approx 1/2, original thickness. Plug harness back in and your done. (about an hours work.) Only other thing that may be wrong is styrofoam drip tray for cooling unit, under cover on roof may have a crack , allowing condensation to leak in. If that 's the case, you can try to find a sealant compatible with styrofoam to seal those cracks.

I have a 1990 rv and the air condition is leaking


The drains for that will be between the upper unit and the roof of the RV. You only have an inch or 2 to see under there so it's pretty hard sometimes, but you should see little round button like things sticking down from underside of the roof AC unit. They have holes in them, and can usually be unplugged with a stick, or piece of wire. If you can't get them cleaned out, you will have to make sure you shut breaker(power) off to unit, and remove the cover by taking out the 4 big Philips head screws. That will give you access to clean out holes in base of tray for drainage. If your getting dripping inside when unit not running but raining outside, then gasket will need to be changed.

Roof leak from seal between AC unit and coach roof


Not very often that occurs but possible. If it has been running well for quite a while and not leaking, just double check that all 4 bolts are snug, but don't tighten too much and compress the gasket too much. I suspect that drip tray may be cracked, or drain holes plugged, and that is what is dripping inside. If it doesn't leak when unit is shut off, and it's raining, then I would pull the cover off, and check for blockage in all the drain holes. In order to properly clean 2 drains at evaporator coils (rear of AC), you will likely have to remove screws holding cover over it, and carefully lift it up and out of the way. Hard to see, but there is usually 2 drain holes in there, one on each side, and the tubes get plugged as well. Make sure power/hydro is off to unit for safety. If it does leak when raining, and unit off, then I'd say gasket needs replacing.

My a/c is leaking from the ceiling of the rv. i cant tell exactly where, but something isnt draining properly. does anyone have a clue as to what i can do about this? my rv is a 1989 model. the a/c is cold...


Look between roof & base of AC unit for little round button like pieces sticking down, which are drains, that have holes in sides that get plugged up. poking with a piece of wire or similar in that hole may unplug it. You should see at least 2. Depending on what type of AC unit, it may just be holes in base for drainage, but if necessary to unplug, you can easily remove cover. Coleman has 4 big Philips screws on top to remove & dometic has a bunch of Philips screws around lower edge to remove & cover will come off, to check where plugged. Make sure power is off inside.(breaker) You should see a trail of water across roof from AC when running & cooling, if not plugged. There is the posibility of a cracked drainage tray allowing water to leak inside as well on some of the older models. You should be able to inspect all of that when cover is off on roof. P.S. CAREFUL! Observe before lifting cover off for wasps in the area, as not unusual for them to make nests under cover. Be prepared, or do on cloudy day, early in the morning, or near sundown when less active. Also, if dew on roof, could be slippery.

ROOF TOP AC UNIT ON COLEMAN POP-UP LEAKS


Does water drip out of unit on the roof while running ? If you look under the unit on the roof, you should see one or two little drains sticking down., that may be plugged up. Piece of wire or something and poke in the holes on the sides of those drains to make sure they're clear. Usually there is a plastic/nylon pan on roof unit to catch that moisture, and drain it off. Could be overflow because of the plugged drains, or I have seen the odd one crack but not too much recently, mostly back 5 yrs ago or so they had a run of them.
