Do you have to refill with freon? the unit I got does not seem to be bringing the temp in the room down below 85

compressor not running or low on freon i woud say compressor.

Sounds like it could be low on freon I believe these units have about 1.5 pounds of freon in them and are critical in not undercharging or overcharging them if it is a freon 410 ac unit the pressures should be about 135 and both lines cold if is low on freon a service tec will need to be called to try to repair the leak if possiable

Its going to take a hile to cool down a hot room . have you cehck the filter? while your at it wash it out . what is the temp of the room and the temp of the air coming out of the unit?

Check the supply air tempeture and the retun air temp.. to do this you put a termitor where the air come out and take the temp. then you check the air at the return where it goes back to the blower. you shoudl see a 15-20 degree diffrence. the oterh thing MIGHT be that cold air is heavier than warm air so it sinks down stairs. close off all the rooms upstairs might help .

Hi,
The unit has a leak and is low on charge (freon) Find and fix leak, then vacuum and recharge...Leak is probably in flare fittings behind unit...
Here is a tip about troubleshooting your air conditioner...
There are many things that can cause your air conditioner not to cool...

AirConditioner Trouble - Review the Possibilities

Let see if I can help. The numbers don't come up so we'll just try your information.

Exhaust - should be closed when using for Air Conditioning
Energy savings turns the fan off with the compressor when set for Air Conditioning
Fan Only means just that (no Air Conditioning)
Fan speeds Quite same as low, Norm same as medium, Super same as High
Temp settings, what the thermostat senses before cycling compressor.

Yes it is! These are sealed systems, so if the tech made no effort in locating your leak, it will continue to loose freon. We are required by the E.P A. law, to make every effort we can to locate the freon leak. We can get away the first time, but always check for any signs of leakage. How much freon did he add? Should say on the service order as we charge by the lb. Look on the data plate on the outdoor unit to see what it holds, and compare how much was added. The compressor is working overtime trying to keep up. I would schedule a leak check to take care of the problem. They will not let us keep coming out to add freon with out finding the leak, its changed so much do to our o-zone layer. Please rate me on my help to you.

The E.P.A. keep records of our freon use, and where it goes.

To manually operate the thermostat set the system to cool and fan to auto then press the HOLD button one time then release, you will see the hold word on the screen after that up the UP or DOWN arrows is setting the desired temperature.

If it's only 92° outside and the unit won't cool the house, then the unit is either to small or it's low on refrigerant. They are designed to cool a house with outdoor temperatures up to 115° to 120°.Usually you need one ton a/c for every 400 square feet of house, but, you have to take into account for average outdoor temperature and humidity, windows, doors, especially sliding glass or patio doors and which side of the house they are on, insulation in walls and attic.
The air leaving your duct work going into the rooms should be about 20° lower than the room temperature, if you have a 80° room then the air leaving the duct should be around 60°. if it is then the unit is probably to small if, everything is working properly.

An 11'500 btu Is appr. 1 ton of cooling capacity or enough to cool approximatly 450 sq ft of floor area. Be sure to read the instructions of course and be sure that all the packaging material was removed that may be restricting airflow. On high you should be able to easily feel the air blowing 10-15 ft from the unit and the air should be dropping about 15- 20 degrees when it exits the unit. So if the room temperature is 85 degrees the air exiting the unit should be around 65 -70. The amount of time it takes to cool the entire room depends on how big the room is and how much and the intensity of the heat infiltrating the room and the number and heat output of appliances and people in the room. Hope this helps you out GL!
