The indoor fan motor and capacitor need to be replaced. In some cases it is only the fan relay. On newer air handlers this relay is usually part of the circuit board. Therefore the circuit board will need to be replaced. It would be in your best interest to have a technician give you a proper onsite diagnosis for this. I hope this helps:)

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.

Why does my home A/C unit result in a constant stream of water coming out of the overflow drain? I've had the same unit for 5 years, and it seems that it drains water in ever-increasing amounts. Als


Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow

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.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed

A/c fan not working=thermostat is working(central a/c system)a/c


The fan on the outside unit is powered from it's 240 volt source. Check that the breaker for the outside unit is not tripped. Also, a contactor is inside the outer unit that starts the fan - it may be faulty.
