You do not mention the model, I presume that it is a cassette, in which case the float switch is located in the indoor unit. You have to remove the cover which is 4 screws. First make sure all power supply is turned off. Then remove the drain pan which surrounds the fan blade. You will see in one corner of the unit a slightly deeper part of the drainpan, this is the corner where both the condensate pump as well as float switch is located. Before you do any of this, give a serious blow into the drain pipe from outside and this may dislodge any sludge which may be causing the floatswitch to stick. You can also pull out a rubber plug which is under the pump on the drainpan.

How do i deal with the dripping of water from my Mitsubiishi split system from inside unit? Will putting the unit on 19 and then turning it full bore clear over condensing?


NO
the water is condensation from the humidity in the air turning to water on the cold evaporator core
normally it drips into a tray and drains away outside
if it is inside ( running down the walls it indicates
the drain hole and tube is blocked or the evaporator core is covered in gunk and holding the water up and not dripping where it is designed to
Call an accredited ac specialist shop to clean the fins and drain tube

Cooloing is not coming down from room temperature


The unit needs service. Call a technician! You can:
Check your air filters
Clean outdoor coil by turning off all power at breakers and tstat, clean o.d. coil with water hose
Inspect indoor coil (if you can) for build up or debris
Other than that? May be low on freon. A service tech will cost $ BUT not having the unit service will cost more due to electrical consumption and excessive run times shortening the life of the system.

Only recently my portable heller air conditioner is oosing out buckets of water each night. does it mean it finished and needs replacement,


Portable air conditioners cool the air, and in so doing, dehumidify the air. The "buckets" of water are coming from the humid air in your environment, so you need to do things that will reduce humidity, of be prepared to empty the condensate receptacle fairly often.

Using a small room, closing doors and windows to the room you want cooled, avoiding cooking or heating water, reducing the frequency of people walking into/out of the room and limiting the number of people in the room will all help in reducing, and keeping low, the ambient humidity.

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.
