I have been having the same problem, only I've had THREE separate techs out to "fix" this. Each one uses the "most powerful" stuff in the industry to clean my coils, then lectures me on using candals (when I NEVER burn candals). One even suggested I get rid of my dogs. They claim there is a waxy buildup on the coils that prevents the water from trickling, and instead it drops down to the ground (where I've now put buckets that I have to drain with my wetvac everyday). When I use my fingernail to try to find and see this waxy buildup, there is none...and my coils are squeaky clean. They also claim the coils are in great shape, no holes, not bent, etc. What am I to do? Additionally, one tech complaimed that my coils were at a 45 degree angle and that gravity was just working against me, but if that were the case, the other 200 townhomes in my neighborhood with the same exact unit would also be having this problem.
