Most problems are originally related to dirt....
Many are refrigerant related.....
Very very few are electrical (not caused by dirt or refrigerant)......

Shoddy work that makes the equipment fail, due to working outside of its specifications! :(
Then, lack of maintenance.

Air flow problems cause many of the conditions listed.

Homeowners that try to install energy saving automatic setback thermostats. They remove all of the wiring, then try to install the thermostat.Don't bother to TAG any of those wires! Then they know they are in trouble. Then they have to call me. :) Think of all the money they could have saved to pay for all of that energy they use to keep cool. Too bad they have to give it to me for a service call. So much for saving energy and money! :)

It does not matter what the most common problems are. We are not in the business of throwing dice.
What matters is the problem the system you are working on actually has!
Use your troubleshooting skills and determine what YOUR problem or problems are. Often, systems have multiple problems. A system that has not been maintained usually has multiple problems.
