You need to use a leak detector , the points that has potential to leak is in the joints , fittings, but you need also to check all portion of the pipes. including the cooling coil, and condenser coil.

Stuff frozen is usually where the leak is. It's under high pressure and when it leaks out the pressure drop causes the freeze.

Cost to fix is a guess depending on where it is. If the evaporator is what is leaking, you probably have to buy a new one and it'll be $1500-$2000. If an excessible line is leaking, it probably won't be all that much for them to solder it.

Good luck.

MY AC WORKS FOR FOUR HOURS PER DAY AND BARELY COOLS DOWN THE HOUSE, NOT MUCH AIR COMING UP TO THE UPSTAIRS OF THE HOUSE. AFTER 4 HOURS, THE OUTSIDE UNIT SHUTS UP AND NOT MORE COOL AIR COMES IN. BEFORE THIS...


I am not understanding exactly what is happening with your unit. You say it only runs for 4 hours a day and then say that after 4 hours the outside unit shut off. But you don't describe the condition of the outside unit! Is there ice on your outside unit after it runs for four hours or is it so hot that the housing would fry an egg? Since it works for four hours and then stops working, I would guess that ice forms on the condenser grill which tells the thermostat that your air is much colder than it actually is. Then it takes time for the ice to melt off again. Am I close? If so this condition is usually caused by your unit being low on freon making everything work harder. But it could also mean that you have a leak in the system somewhere. But it shouldn't be much of a leak or it wouldn't run for the 4 hours.
I would recommend you charge it to the correct level and then check for leaks.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

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.

Hi have central air . Unit working ok but noticed not blowing cold air . The fan outside is working , Unit comes on . Could it be feron . unit it about 7 years old . Purchase house about 4 years ago


You need to have a pressure gauge the reads for R-22. (Freon) It sounds like the system might have a leak. Look for a wet place any place on the units pipe system. It has a little oil in with the freon that is forced out of any leak. If you see a wet place this is oil. It is also the location of your leak.

Central AC unit not cooling


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.

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
