Is the condenser outside unit working. (Evaporator is inside the home.) If so you may be low on refrigerant. Have a qualified technician test it.

My hotel room ac is blowing cold air just not strong enough to cool entire room

It may be frozen over. At the front of the unit there should be an air filter. May be behind a panel that opens, or it may slide out. Behind that filter will be the indoor coil or evaporator coil. Look to see that coil and if there is any ice on it. It will be a white ice covering the coil. If it's frozen up, turn the cooling mode to off, turn the fan mode to on, and let it run at least a couple of hours to thaw. Let maint. know it's frozen up and needs service. Get what you pay for! If it's not frozen up, find some way to check the supply air temp. Some sort of a thermometer. It should have a 50-60°f supply air temp, depending on the indoor temp. Most I've seen will supply 45°f, but 50-60 is a good reference. Hope this helps! I bet it's frozen up.

Only blowing hot air and red light flashing on panel. Also no noise from the main unit on the balcony which is usually loud when a/c in use

Whenever there is problem in unit, the error code will be displayed. Please check. As per your statement, it's communication error between indoor and out door. Check power in out door unit.If not check your temp setting.
To get proper cool, keep the tips as follows:
1. Check air filter is cleaned. 2. Check indoor coil is cleaned. 3. Checkindoor blower motor is working. 4. Keep in cool mode. 5. Set temp minimum 3degrees less than room temp.6.Check compressor is working . Thanks.

Why doesn't it get cooler ?

you may have a dirty condensor coil its the coil near where the warm air blows out or maybe a dirty evaporator coil its where the air gets sucked in check both of them and then see whats the air temp going into the evaporator and the temp. coming out of the vents that blow cold air the diffrence should be about 15 - 20 deg f let me know what the temps are ...but first clean the filter and both coils

AC is running continously but it is not cooling.

You mean the evaporator has no condensate? Is the condensor hot? It sounds to be in need of servicing. The temp coming out of the evaporator should be 10 to 20 degrees cooler than the air in the room which is being blown through the evaporator to be cooled. No condensation, either low humidity or no refrigerant in system. You may need to call an a/c repair. Good Luck, Ned---- The condensor is the outside unit and there should be no water coming from it and it should be blowing hot air

Air conditioner and heat blower

You will have two fans, one fan blows out the rear of the unit that cools the condenser soil, one blows out the front across the evaporator that blows the cold air out into the room. Some window a/c's have whats called a squirrel cage fan assy. that has one motor that runs both fans. So you either have one bad fan motor (the evap fan motor) or you have a bad fan blade that has fallen off the shaft. Also check the filter see if it is clean.

The 10,000 BTU portable room a/c unit is not running cold enough

Make sure your vent is closed. check the filter to see if its clean. If you run the a/c you can check your evaporator to see if you have condensation or does it freeze up?
Make sure you have your unit on early in the morning. If you turn it on in the afternoon the humidity might be too much and it will take along time to cool down.
Try those things if that doesnt work then you need a service call.

Rheem Criterion II air conditioner runs but it does not cool

Check air temp out vent should be approx 20 degrees colder than room temp if it is your unit is too small for the amount of space you are cooling.Rule of thumb 1 ton(12,000btu's) for every 400 sq ft of uninsulated space
