After twice paying $65 for a service call where they attach a vacuum to the condensation line on the outside, I went out and bought a shop vac for $35. Last Labor day the AC stopped, I saw that the check valve had water in it and employed the shop vac. Sucked the goo right out and was back in business in 15 minutes.
And on a monthly basis I pour hot water into the condensation line to keep it clear. Was told to never use anything but water or vinegar...
Had the same issues up north with a drain line that wasn't exactly all downhill....
