The unit outside makes a loud noise & blows cool air. For the last 2 years we have had to put freon in it. We were told we had a leak in the A coil. We just paid someone $996 to fix that. Now our unit is loud & blows cold air & inside is not cooling off. Right now it is 80 degrees in our house & the air conditioner is on & fan is running outside. HELP PLEASE!!

Re: outside makes loud noise
I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

sounds like it is either low on Freon or the compressor is going out. The blowing ice cold is an indicator that it may be freezing up because the low Freon. when it stops blowing cold, turn it to fan only mode and see if it gets colder again. If that is the case then the unit is low on freon and freezing up. I know that sounds confusing but that is how AC works. The low freon pressure means the gas is expanding too fast and the air flow cannot take up the cold from the evaporator fast enough. Turning the compressor off and keeping the fan on will alow the room air to take up the cold.
No Freon doesnt evaporate the only way you have to charge an A/C unit is if it has a leak somewhere in the system. It sounds like your compressor is locked up I would try installing a super boost to the Condenser (outside unit). Let me know
If both fans runs (inside and outside), check if the compresor runs , if does probably the unit is low in freon and needs to be recharged after the freon leak has been fixed (remember this is a seal system and it shouldn't leak), but if the compressor doesn't work , it could be the capacitor , the pressure switch (if it's low on freon ) or the compreessor itself.But befor do anything ,if you have a digital thermostat replce the batteries.
Check and see if it is froze up. Check big line at outside unit for ice. check filter and replace as needed. Check outside fan to see if it is running. Wash out outside coil If fan and compressor are running and has hot small line at outside unit. If not froze up and coil is clean you will need to call in a pro. If compress over heated you may need to wait for it to restart if coil was dirty. Again make sure out door fan and or unit is running and clean.
If you have access to your piping system you may use a soap bubbles to test the pipe connection. the leak gas will blow the bubbles if there is leaking. But if your system is out off freon gas, you can not use this method. just try it check the connection first put the bubbles around it.
Sounds like you have a freon leak or your compressor has stopped working. You will probably need a service tech. If it is out of freon, don't let them just add more freon, make them find and repair the leak first. Good Luck.
