Can someone please tell me the cost of re-gassing my split system air conditioner.I've been quoted 700 for 3 kg of gas.?

The typical labor rate varies from place to place but you can use an average labor rate including the service call for around $100.00 dollars and add around $65.00 a pound for R-22 freon which should be in the area of $529.00 dollars total for parts and labor plus tax...........
