what is the average cost if there is a leak in hose in air conditioner? on 2003 Hyundai Santa Fe

for about 6 mos, I believe I have had no cold air from air conditioner. there is no Freon at all. thank you for any information you may have.

we would charge the A/C up and it would only last a day. Found the O-ring leaking on the compressor. The factory puts the two pieces of the compressor together and seals it with an o-ring. the only way to fix it is replace the compressor like I had to do. you can use soap and apply it to the middle of the compressor to check for leak, you need to add some Freon in order to check it. hope this helps.
