AC Not Cold Due to Pressure Hose Leak on Nissan Altima

The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.

I had a new engine put in my car in 2010 due to an engine recall and every since my car has not been the same. My air conditioner is blowing hot air I had it serviced but now Nissan is claiming I need to put over $1200 to get new hoses but I refuse to put another penny into this car. I will never purchase another Nissan!
Looks like a tiny pin prick hole near the crimped area.

Ac blows but it's not blowing as cold as it used to. Makes like a empty air can sound when i first turn it on

I have had this problem for a few years now and decided to look at it. Long story short, low pressure hose had a pinhole where it was crimped. I just put some self-sealing 3M tape on it and refilled my "refrigerant". It got me through the summer but now it's leaking somewhere else. I'll probably just continue to refill the refrigerant. For the cost, it's going to be better than replacing it with another $200 OEM hose. I'm never selling the car so I might as well just wrap all the leaks with that self-sealing tape. That stuff is magic.

I have not solved it, but the car usually blows slightly cool air even when it is set to Max A/C.
