Rain runs off the roof of my home and pours into the AC at ground level. This can't be good for the unit - can it? Can you install something like a rain hood over the unit to keep that direct runoff from pouring into the unit? Gutters don't seem to stop the heavy runoff during heavy rains. Suggestions?
If your condenser blow air up through the top of the condenser and you are concern about rain water affecting the unit.
You can install a roof or rain hood about 4ft above the unit to keep the rain off, The unit must be able to blow air off without causing Hi head pressure to affect the unit, The condenser must breathe or desipate heat freely.

If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.
You are <b>building a log home</b> or a home that you want the rustic look of the <b>floors above also being the ceiling of the floor below</b>. You hate the thought of having to install ugly <b>heating and air conditioning ductwork</b> in your new home. For you there is hope. You can still have a comfortable home and have the look that you want.<br />
The advancements in <b>ductless heating and cooling</b> has made it possible for you to have those wood ceilings, roof lines, wood walls, and everything you can think of. The new <b>ductless HVAC units</b> take up very little space on your wall. They can be placed almost anywhere with a little planning, and they are<b> very efficient at both heating and cooling</b>.<br />
The many features do not stop with the<b> heating and cooling</b>. Most units have remote controls to run the unit. Many of these units can run <b>multiple inside units from one outdoor unit</b>. These units are so quiet that you have to feel the air coming from them to see if they are running. The installation has been simplified to the point that they can be installed very quickly by an <b>experienced professional</b>.<br />
If you are concerned about the looks on the outside, that too can be fixed rather easily. The <b>piping and wiring going to the indoor units</b> is relatively small and can be hidden in many ways by using a little imagination. Colored aluminum can be fabricated to cover the pipes. I have also run the piping through rain spouting and made it to look like just another rain spout coming off of the roof. <br />
If you are looking to build or remodel and are worried about the look you will have on the inside, then take a look at <b>ductless split heat pumps</b> to give the comfort and the looks.<br />
Good<b> heating professionals</b> can find many ways to make these units work for you. Make sure that you do not settle for something less than you want. You may need to look at more than a few companies to find the one that will give you the system that you want.
Check the bottom corners, one of them has a white rubber hose coming from the unit and may only be patruding out a little or you may need to look from close to the roof level to see it. Run a flexible wire, say #14 THHN into it about a foot to 18" and rotate it as you push it through. You should see debris and water coming out when its cleared. Yes, splashed rain can contribute to the full collector tray and leak through the duct, and so will a bad roof gasket that is between the roof and the unit. If you still have a rain leak after the tube is clear, then change the roof gasket. Good Luck!
Sounds like base gasket at roof is loose or defective to start with. Try removing ceiling assembly enough to tighten 4 bolts that secure roof unit to inside bracket. Do not compress too much, just snug them all evenly and see if water slows or stops. If not, you will have to remove upper unit (roof) and replace gasket and re-secure but don't tighten to excessive, only compress gasket approx half of original thickness. Also make sure upper unit is aligned properly with opening of roof.
This could be a lot of things, there is a contactor relay in the system that might be bad, there is a possibility the contactor is not getting voltage, there could be corrosion issues with connections or a bad start capacitor.
Once you have installed the jumper, you will need to kill power to the furnace for about a minute to reset the board. Make sure the the jumper is making good contact. Sometimes they appear to be plugged in but still are not making contact.
No, the units are sealed and the rain should not have affected the system at all. I would remove the outer cover of the unit and access the capacitors. Your start capacitor may be bad. You can visually inspect this and tell if there is a problem. Small black relay on top of capacitor often burns out, if so, replace capacitor and relay. If this looks fine, then we need to start at the thermostat and work our way forward.
They say you should only compress the gasket to approximately 1/2 it's original thickness, and sometimes there are tabs that touch roof to tell you that's far enough. If your sure it's coming in around gasket where it meets roof, try loosening bolts off to allow you to lift upper unit off roof enough to use a caulking gun with a tube of "dicor" self leveling sealant, and run a bead of Dicor around where gasket meets roof , then set unit back down, & tighten until gasket is about 1/2 thickness as new.I always find it better to remove bolts & flip unit on it's side and get good bead down center of where gasket meets roof, then set unit back down, line it up & snug it down.Let it sit for a while to set a bit. Be ready with a rag to catch or wipe any excess that squeezes out from under gasket to the inside, that may end up on floor below, as it's very hard to remove that stuff after the fact.Has worked for me in similar situations.
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.
