How much does it cost to have free-on put in one compressor and to replace one of the copper pipes?
It somewhat depends on what you're wanting freon put into. If it's a window A/C, there's a good possibility that the companies in your area won't even bother with it. They claim it's more money than it's worth.
If refrigerant is needed there is a leak that should be found and repaired before recharging it. Maybe that is why the pipe has to be replaced. Cost depends on how much refrigerant, how much labor and how much pipe. You have no details of what you have but a guess for costs might be$500-600.00
You will be able to hear an exhaust leak, if you put to mush fuel treatment in the tank, you could cause a fire at the converter, Good Luck !
