Texasmark hit the nail on the head as far as what the slingers do on the condensor fan blades. Actually the older versions also had slingers and did this to an extent but still had a drain extend out the back for the majority of condensate to flow. The manufacturers do not care if they develop a machine that needs to have a higher degree of maintenance to maintain the rated efficiency....all they care about is the efficiency rating as it is tested in laboratory conditions. Kinda like gas mileage estimates in a car or truck !!!!
The dirty condensor (outdoor) coil is responsible for rejecting the heat transferred (via the refrigerant) from inside the house plus the heat of compression added to it by the compressor. As stated by Texasmark, the pressure and temperature of all refrigerants is directly proportional and it requires more horsepower (wattage) to do the work at the higher pressure caused by the airflow blockage created by the crusty dirt accumulation on the coil.
Efficiency goes down dramatically, the system runs too hot because of the high head pressure, the compressor begins running hotter because the warmer returning refrigerant doesn't cool it properly and eventually the compressor will cycle on its external thermal overload (internal on most single phase compressors of a capacity larger than around 12,000 btu). It becomes an endless circle unless it is kept fairly clean by annual cleaning.
WWGrainger will sell a acid based coil cleaner called "Foaminator" for around $14.00/gallon. It will foam profusely and force unbelieveable amounts of unseen dirt from between the fins. It is to be diluted and sprayed on with a pump sprayer and rinsed with a hose. It is friendly to the environment. Works wonderfully, just follow the directions.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
