I know this is a generic question with not a lot of detail but on average how long would you say it should take to change out a semi hermetic compressor? I do not have a lot of experience with service work but have been in sheet metal a long time and now I am in the office and I have a service guy changing one out at a local grocery store and one of my inside office guys thinks it is taking him too long. How many hours do you think it should take to change out? I had a crane there to get the old one down and the new one up. Thanks for any feedback you may have and I look forward to joining in on discussions with this community in the future.
