Looks like a valve in our fridge compressor is bad, so the compressor needs to be replaced. This is for a Sub-Zero 700TC integrated unit. I can purchase a new compressor for $350 less than what I was quoted for the part. How do the appliance repair companies look at clients purchasing their own part(s), especially after being quoted for parts/labor already? If they are ok with it and will install for me should I expect the quote for labor to stay the same?

Thanks for the help!
