The compressor is not compressing. Either the compressor isn't running or the freon has escaped.

    How good are you as a mechanic?

    This is tough! A compressor with no freon sounds pretty much like a compressor that's not running. If you have an amp meter, you can watch the compressor use electricity, or not. Without any meter at all, you might have to touch the compressor to see if it is vibrating.

    What you should hope for is "compressor not running". Repairing freon leaks is way expensive and impossible to do without special tools. Even topping up the freon requires pressure gauges and a license to buy freon. An electrical failure is way cheaper and easier to fix.

    I suggest you open the cover on the outside half and look at the wires, relays, capacitors, to see if something is corroded or come loose. After that, you have to use electrical meters to see if things are working.

My outside toshiba split system is leaking a lot of water

If the unit is on heat mode, the outside unit is the "cold" end... Sometimes if the ambient air temperature is very cold ( Under 5 degrees C), the outdoor unit can start to ice up. If it ices up too much, the air con will automatically go on to a defrost cycle where the outdoor unit will heat up and melt the ice. Water is then drained out the bottom.. its the opposite of what happens in the summer when the indoor unit has water running out of the drain hose. Especially on humid days..

The compressor and fan in the outdoor unit is functioning alright but the indoor unit fan is not blowing in cool air , in fact my split ac is not cooling at all. Is it something to do with the refrigerant?

Hello, first touch both pipes while the ac is running, the pipe with insulation should cold with condensation and the small pipe should be warm. If they are both warm then the unit is very low on refrigerant or completely out of refrigerant due to a leak, if this is the case you will need a hvac tech to come out, repair the leak, and recharge the unit.

My samsung split ac is not cooling. there is air blowing no cool air .before the roomwill get cooled within 30 minutes.

could have leaked out all its gas. if its an older unit it may be cheaper and easier to replace the whole unit. will make a buzz noise occasionaly from the outdoor unit. this is the compressor tring to pump the gas that is not there. check if the fan on the outdoor unit turns on.

Fan doesnt work on heat cool ok

Often the fan will cycle on and off on the heat mode. A cold air prevention mode is often built into modern Ac units whereby the indoor fan wont turn on until the internal system pressure is up to a certain point and heat is available to pump into the room. If the system cant come up to pressure or temperature then possibly the system is low on gas. Place your hand on the large pipe leaving the outdoor unit, it should be HOT when the system is on heating mode and running. If not Hot, then it is low on gas.

Does not heat or cool

Hi, If the outdoor unit is running, make sure the fan is on also. If the system is new and has just been installed, it sounds like you may have a freon leak and have lost all its freon. Turn it on cool and let it run for a few minutes. Go outside and grab hold of the larger copper line coming out of the unit. It should be nice and cold and sweating. If not, and the fan and compressor are up and running, you have a leak and lost its charge. Check this and get back to me and let me know what you have found. We can go from there.
PS, When these installers put these units in, they sometimes get in a hurry and there welds are not very good and will leak over time, just to let you know.

Air Conditioner compressor not turning on

Check the following:

* The outdoor condesner coil to make sure it's clean

* The outdoor condenseing unit to make sure the fan runs

* The circuit breaker for the A/C condenser and any other circuit protection , if present

* The regrigerant charge

* Wiring connections

* The thermostat setting (make sure it's calling for cooling)

Samsung 1.0 ton(split) AC stops working during 36-37 degree C.

i believe you have a high pressure switch on your condenser that is going bad .it is a switch that has two red wires connected to it inside your outside unit
