Is there a sealant that can be shot into the suction line and can it seal micro leaks in the evaporator coil? Sort of like Fix-a-Flat but for air conditioners. I was told that it can buy a couple more years service out of an aging evaporator coil. I've only lost about 5 degrees of temperature drop across the coil from last year when the hvac tech fully charged the unit. It uses the old refrigerant, R100 I think.
