We had a service man come out and he added freon to our air conditioner, he also checked for leaks. It blew cold air for about 10 minutes and stopped blowing cold. WHAT COULD BE THE PROBLEM? The filters are clean and everything seems to be working fine except it will not blow cold air.

Re: Turbo air not blowing cold air
I don't understand why someone would just add freon to a system.without checking for leak and fixed it .
Only way for refrigerant to loose refrigerant is by a leak .
I think the Technician that way there know the problem but don't want to fixed it because if unit work for 10 minutes and Technician is not around then something is wrong

A mechanic would check the system with a set of pressure gauges. If the compressor is running, the low side would read around 30psi and the high side would be around 250psi. That is how you know if the system is full of freon or not. You may have to get a professional diagnosis to proceed. If you replace the compressor, the accumulator needs to be replaced and a vac pump is used to pull all of the air out before the freon is added.
Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.
When self adding freon after it leaks out you get air trapped in the system. After adding freon a couple of times the air expands not leaving room for the needed freon. To continue adding freon with air tapped will knock the compressor out pretty quickly, there's not enough room for both & the air is keeping the freon from being able to cool properly give the false indication of being low on freon. The freon you are adding has the dye added to assist in finding the leak since freon does not evaporate nor dissipate it its being leaked out. A black light will assist locating the leak. The best thing is to have the unit checked & serviced by a mechanic...he'll charge about $ 150.00 to check for leaks, remove the old freon...his machine will tell him how much air its trapped in the system by how little freon is removed. For the service fee he will replace valves & gaskets, where needed, correcting most leaks. After sucking the system down & recharging the problem should be corrected.
Hello, you can add freon by installing a piercing valve on the low side of the system. Before adding freon I would check and make sure the air filter and both coils are clean. If everything is clean then most likey the unit has a leak and is low on freon.
Sounds like the compressor has gone out of your AC system. They are not too terrible to change, but can be time consuming depending on location. IF the freon is good, check the compressor and you should here it at idle speed w/ hood open clicking on and off as the clutch engages and disengages when the AC is operated. If there is no clicking on and off by the compressor, new compressor will be required. IF it gets cold when first adding freon, and then fades quickly, it is likely a leak in one of the high or low sides of the lines between the coil and the compressor.
Sounds like you have a good sized leak in the system. The service man should be able to locate a leak that big. You might be able to locate it yourself. It's more than likely in the outside unit or indoor coil not in the lines that run between them. Look in the outdoor unit and look for any oily spots. The compressor has oil in it and it will show up where there is a leak. Look for any pipes that may be rubbing together as this will rub a hole in a line. Look at the indoor coil looking for the same indications. Hope this helps.
