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.

The video gives you an example of the defrost cycle!

main reasons that cause ice on suction line

-low evap air flow
-low refrigerant
-low load
-liquid line restriction (possibly filter drier)

Wen was the last time you replaced the cabin filter? Open the glove box. In the far back you will see a plastic cover. Remove it and you will see the access door for the cabin filter. Remove the door and pull out the filters. There will be two of them. I'm going to bet they are filthy and possibly even have there own little Eco system growing on them. This is pretty common.

These have always been a problem. I would contact your hvac supplier and ask for a roll of 'hog hair' filter media. Most I;ve seen is green in color. It is cut to fit, but you can fasten it to the inside of the front panel with two-sided tape and or zip ties. Hope this is helpful.

first you have to have a EPA certification too purchase, and to handle Refrigerant. in order to stop the leak first it must be located and in most cases soldered shut depending on the leaks location if the leak is in the tube sheet of the coils it my be better to replace the leaking coil. if the leak can be repaired the refrigerant must be removed from the system, leaving it in a vacuum then bring it up to atmospheric pressure (0 psi) using dry nitrogen. then the leak can be repaired, after leak has been repaired pressure test system at 120 psi for 20 min. watching gauges to see if pressure drops. If pressure holds, release nitrogen then evacuate system with vacuum pump. most manufactures require a 500 micron of less vacuum to ensure no moisture is in system then charge system according Manufactures Specification. charging and service ports are normally located at outdoor condensing unit where copper piping connects too condenser, charging manifolds are a necessary tool for this repair. I would highly recommend having a HVAC contractor preform this repair, amount of refrigerant that goes into the system is critical to performance of heat pump operation.

Hi, if you are running this in cool when the icing occurs, there are several things that will cause this. #1, make sure the indoor fan is running up to full speed. #2, make sure that the indoor coil where the air comes in is clean and that the filter media is also clean and not clogged with dirt. The reason I asked if you were running it in cool when this happens is if this were a heat-pump and you were running it in heat, the ice would build up on the outdoor unit and you would have a defrost problem, so just forget that unless this is happening. If fan is running up to speed good and strong, the filter behind the cover on the indoor unit is clean and not clogged and the coil behind the indoor unit is clean, you will have a freon leak somewhere in the unit. Check what I have told you first. Use a ladder if you need to reach the indoor unit. Make sure all is clean and if the foam type filter is old and rotten, you can get some at a hardware store, like Home Depot, Ace Hardware, and so forth. If it continues to ice up, you do have a small freon leak and this will take a certified service tech to locate leak and recharge the system. Most leaks occur on these ductless splits at the freon lines where the lines screw together at the indoor coil to the outdoor unit. I have seen this happen many times as a A/C Refrigeration contractor. You do have a top of the line system I have to say, very little calls to make repairs on the Mitsubishi split system. Lets hope its just a coil or filter that is plugged up not letting air through the coil which will ice up the unit. Keep me posted and feel free to correct me if I was wrong about the way the unit is set up.Also, keep me posted on what you have found and if you have or have not solved the problem. Please get back to me.

Do not run it on maximum cool and fan on low. Freezes up all the time this way.

On a "Non Heat Pump" unit, icing of the pipes is not good. It is an indication that you either have a low freon level (Charge), low load, wrong superheat.
A low load usually means, in this case, something wrong with the air flow. Clogged filter, wrong fan speed, something blocking the return air grill, like a chair/ blanket, etc.
If low on charge, the evap (Indoor Coil) will ice up and the ice will then slowly creep along the pipe untill it gets to the outdoor unit. This is really no good. Air cannot go thru solid ice so naturally there is no cooling happening.
If a company replaces the outdoor unit (Condensing Unit), there is no warranty on the indoor unit. I do not know of any company that will repair an indoor coil (Evap). Just not smart money. They have to capture the freon, open the system, make the repair, ensure the correct level of freon is in the system, and most time, add a filter/ dryer for additional filtering and drying of the freon. With all that, no one is going to patch a leak on an old coil because if it leaks now, it's going to have another soon. You'll just be chasing leaks and spend money after money. Hope that makes sense. HVAC companys have to follow the EPA rules too. Leaving a system leaking above a certain percent of it's total charge is a major no-no. They will not do it.
Hope this helps clear up a few things and good luck.
