Could power flushing cooling system cause the low pressure hose to leak??

What is your question?

I had a multi point inspection on my car in May 2010. I had standard service done due to time/miles and they had power flushed cooling system and replaced AC filter. I took my car in on Nov 1. 2010 for another multi point inspection at which time I was told to replace the AC Low Side Hose. When I took my car in for an oil change on Nov. 3rd, I was told that the air filter needed changing. I also got a 2nd estimate for the hose repair. On Nov. 17, my AC completely stopped cooling. Could the flushing of a cooling system cause the hose to leak?
