Have an Amana 6300 BTU comfort zone ac if you stand in front of it you feel the cool air but not cooling off a room. Cleaned filter. Does it need more freon??

The window units normally have a sensor thats attached to the front of the indoor coil. This controls the thermostat. I usually pull this sensor away from the coil because it stops cooling before the room is cool. It is attached to the cold coil so it senses the coil temp, not the room temp. You can normally see it when you remove the air filter. Don't break it! It may be a wire or small copper tube

The DeLonghi PACA120E Portable Air Conditioner quickly cools rooms up to 400 square feet and comes equipped with several functions that make operation easy and low maintenance. Its 3 operating modes are supplemented with no-drip technology, an adjustable thermostat, 24-hour timer, and much more. This unit truly takes the work out of cooling medium- to large-sized spaces. Multiple Modes and Functions The DeLonghi A120E-also known as the Delonghi Pinguino PAC A120E-offers 3 operating modes and 3 additional operating functions that make this model versatile and energy efficient. Cool Mode: 12,000 BTUs of cooling power help cool large rooms, offices, or basements. Dry Mode: Reduce room humidity by removing excess moisture from the air. Fan Mode: Circulate air to keep your room comfortable without using a lot of energy. Low, medium, high, and an auto-speed are all included (auto speed selects a fan speed for you). Smart Function: Your AC uses Cool and Fan mode based on ambient room temperature. This function will also select your fan speed and keeps your room comfortable without wasting energy. Sleep Function: Using a low fan speed, the AC gradually reduces operation so your room remains comfortable but the AC runs more quietly and efficiently while you sleep. Boost Function: This function is ideal for the summer months and uses the maximum fan speed to rapidly reduce your room temperature. Useful Features Using DeLonghi's patented no-drip technology, this unit is "dripless" under normal conditions, meaning the AC will discharge all of the moisture collected from the air-so you typically won't have to worry about draining the water. When dehumidifying a lot of moisture in Dry mode, excess water may collect in the internal collection tank. Once the tank is full, the air conditioner will automatically turn off to avoid overflow damage. You can also use the included continuous drain hose as a no-fuss way to eliminate excess water as needed. An adjustable thermostat provides additional convenience by allowing you to set your room temperature. The DeLonghi portable AC will cycle on and off to eliminate over-cooling and maintain the set temperature. Additional Features Washable Air Filter: A washable air filter helps remove allergens and other particles from incoming air and saves you money on replacement filters. Quiet Operation: High efficiency compressor and components result in quiet performance. Electronic Controls: The LCD screen displays the timer and temperature settings, while intuitive indicator lights accompany each operating mode. 24-Hour Timer: This feature lets you program your AC to turn on or off up to 24 hours in advance, so it only runs when needed. Window Bracket: Double window bracket is included with purchase for flexible installation. Self-Diagnosis System: The unit includes a self-diagnostic maintenance system that identifies malfunctions should they occur. Remote Control: Use the full-featured remote control to change modes, set the timer, and select a fan speed up to 23 feet away from the receiver (on the front of the unit). Portability: Easy-roll casters and dual carrying handles make it simple to move this model from space to space.

Lack of air flow or a lack of refrigerant are the two primary reasons why coils freeze. Clean the filter and the coil, if frost continues it is likely low on refrigerant.

The dimensions you gave only equal 230 sq ft. It may seem larger, because it's long and narrow. Even with lots of windows*, you shouldn't need more than 15,000- Btu's to cool the area comfortably. *That's assuming you close the blinds, shades or curtains, while the room is in direct sunlight. Even with a higher Btu output, those "lots of windows" will always be an air conditioners worst enemy. So, in your case, more is not better. In fact, it's a waste of energy.

If you have a ceiling fan in that room, run it on the highest speed that comfortable to you, in a clockwise (looking up at the fan blades) direction. This will help move the cool air around and generate a wind chill. That will make it feel cooler than it really is. Plus, it takes the strain of the AC unit.

I hope this helps you and thanks for choosing FixYa.

you need to find out the size of the unit.
Rule of thumb - for every 600 sq ft of cooling area (in a well insulated house) you will need 1 ton of air conditioning. 1 ton = 12000 btu.
So, if your cooling area is 600 sq ft you would need an AC which was rated at 12000 btu, assuming your house is well insulated.
If it is not insulated well - you might need a bigger unit, i.e. 15000 btu.

Check filter, if you have a 5000BTU unit (small) and it is extremely hot, then it wont work great for a big room. BTU is the rate of what the AC will put out. 5000 BTU is good for a small single room. 10,000 will cool a bigger room and 18,000 btu is meant to cool a home.

Yes they Do they are called Dual Zone Units. At http://www.paylessminisplit.com they are very helpful if you call them they can answer alot of questions about many brands of mini split air conditioners.

The condensate drain line is clogged, causing the condensation water to overflow. You can use a shop vac to clear the line. attatch it to the outlet side of the line. also clean out the condensate drain pan located at the bottom of the indoor coil.

you have a slow leak in your refrigerant and need to find the leak. you will have to get an AC repairman to come to your house and check it for leaks and fix the problem.

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
