Gurgling in A/C pressure lines
This is an Amana whole house central AC unit about 17 years old. It cools and dehumidifies well; the A coil is clean and the drain pan is clean and drains properly. Lately there is an occasional gurgling sound coming from the area where the lines go in and out of the house.
I'm wondering what the range of problems might be and the cost of repair, and if this is a DIY.
Also, is there any kind of lubrication or other maintenance you can DIY, other than just cleaning the condenser coils. Can you oil the fan motor?

I agree. The gurgling can be caused by the liquid refrigerant. It's not a problem that needs repairing.
Most of the condenser fan motors are sealed and cannot be lubricated.
Some blower motors in the air handler can be lubed.
If you're handy..... turn the power off to the condenser. Remove the wiring access cover and inspect the contactor for burned contacts. That would be the most likeliest part needing replacement.
