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 blowing hot air, repair shop wants to replace compressor, condenser, and expansion at a repair cost of $1300.00. This is a respected AC shop in city. Not sure if I should dump money to repair due to unexpected short life span of factory system. never had this type of problem before with other brand of vehicle. Still deciding.
