If the inside fan motor is running OK you are low on refrigerant. If the inside fan motor is not running, repair the inside fan motor. Could also possibly be dirty inside coils.

Unit not working correctly. The unit worked for the winter, few days ago I turn on the AC and noticed that it wasn't cooling like it should.


It's could be the board or a heat relay. See if you have 24 volts on "x2" im assuming, emergency heat when in cool mode if so it's the board. Or unhook black or x2 or your emergency heat from board and run unit in cool. If heat stays on its a relay

Why does my ac not blow cold air?


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds After you turn it back on the system should reset. If you need any other assistance check us out online at Boca AC Service we are always happy to lend a helping hand

MY AC WORKS FOR FOUR HOURS PER DAY AND BARELY COOLS DOWN THE HOUSE, NOT MUCH AIR COMING UP TO THE UPSTAIRS OF THE HOUSE. AFTER 4 HOURS, THE OUTSIDE UNIT SHUTS UP AND NOT MORE COOL AIR COMES IN. BEFORE THIS...


I am not understanding exactly what is happening with your unit. You say it only runs for 4 hours a day and then say that after 4 hours the outside unit shut off. But you don't describe the condition of the outside unit! Is there ice on your outside unit after it runs for four hours or is it so hot that the housing would fry an egg? Since it works for four hours and then stops working, I would guess that ice forms on the condenser grill which tells the thermostat that your air is much colder than it actually is. Then it takes time for the ice to melt off again. Am I close? If so this condition is usually caused by your unit being low on freon making everything work harder. But it could also mean that you have a leak in the system somewhere. But it shouldn't be much of a leak or it wouldn't run for the 4 hours.
I would recommend you charge it to the correct level and then check for leaks.

Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I think I have it covered above. Let me know if you need something more specific. Thank you. Roger

Outside AC unit working, but inside there is no air flow and fan inside will not work unless it is turned manually. Also, a little ice on outside unit.


Depending on what type of Thermostat you have, it is usually as simple as setting a jumper for Electric heat instead of gas.
If you have a digital Thermostat then turn off the power to the Air handler and remove the thermostat. Look closely at the small jumpers and make sure your jumpers are set to elect. and not gas so the fan can run in heat mode.
If you have a standard heat cool mercury switch then same as before with the power and unscrew the thermostat, and where the yellow wire is connected if there is a factory with on the yellow, then move the factory wire to the (A) and put the yellow wire back on the (Y).

Good Luck!

Always wondered why there is no drain hole at bottom rear of unit, so no condensation can drip away-now I find it not cooling well and the bottom front of the condenser is iced up. What to do?


Newer models of window AC's use either a flailing fan to spin the condensate out the sides of the AC (outside the window) or the heat of unit and outside air will evaporate the condensate.

Either way, any excess will spill over the back edge, hence the reason that manufacturer's recommend that the AC be installed with the rear of the unit slightly tilted down to prevent excessive condensate (water) from building up and/or coming inside the front of the unit.

As to the icing, it could be that the unit is undersized for the space you are trying to cool and can't keep up and is running all the time in an attempt to cool the air down in the room you have it installed in. Try letting the unit "defrost" by shutting it off for awhile (until the ice melts) and then keep the shades pulled and the door closed once you restart it. I also tell people to give the AC a chance to adjust by setting the cooling temp to around 10 cooler than the present temperature of the room.

It's really hard to completely cool down a hot room all at once, so unless you're willing to let the unit cool it down in stages, it might not be able to ever get a 90 degree room down to 65 degrees in one day, if ever. Give it a try and see what happens, otherwise, you might need a larger rated BTU unit to get the cooling you desire.

You either have a refrigerant leak or a dirty inside coil or a slow running inside blower motor.
Set the thermostat for heat and run it until all the ice is thawed. Then check the incoming air side of the coil for lint and dirt. Check the fan motor for proper speed. If you have service gauges your low side pressure should be approximately 68 psi. If lower you have a leak.

Not blowing cool air on my Ruud, 18 years old, outside unit.


If you have ice on the Line you are iced up. If coil is iced no air can get thru. Now First. Turn of ac and turn fan to on posotion. That will thaw unit. Let it run 45 minutes. That should do it. If the fan is not running you amy have a bad fan relay. One of the reason iced up unit is dirty evap, coil inside. Try to thaw it out first. You can clean the coil with a stool brush. Does not damage the coils. Good luck
