NBC complaint: Service through American Home Shield

I called American Hone Shield on July 25 to inform them my AC was not cooling. They charged me the service fee of $75 and sent someone to see what was wrong. The gentleman told me the compressor was gone and I had two options either replace the compressor or request a cash out and purchase a new unit.
I have already replaced a compressor in this unit so decided this was going to be a recurring problem so it is more feasible to replace the unit having spent monies fixing this unit numerous times.
I contacted Home Shield who went ahead and ordered a compressor which would cost me $1700 out of pocket.
I asked the service company not to accept the compressor because I believe it is better to replace the unit due to it’s age as well as what it has been costing to keep it running.
Home Shield has offered me about $947 with a bunch of stipulations.
I inherited this contract from the owner of the house when I bought it over 14 years ago so I do not think I am being treated fairly.
I have not yet responded to their offer because I feel it is an insult and have been enduring this heat since I contacted them.
I have been doing my best with fans and I am seeking any assistance or advise I can get to resolve this issue amicably.
