No cooling. Upon arrival I found system was severely low on refrigerant. I advised NOT TO charge the unit and to replace it. Customer insisted that I charge the unit to get them through the weekend. I added 10 pounds of R-22 to bring system up to operating pressures. I advise customer that there is no warranty or guarantee on the refrigerant. Customer needs a quote for system replacement as soon as possible. I also replaced the media filter for the main house furnace and left the filter for the addition for the customer.
