Or, you don't actually know how to read a set of gauges and charge a system correctly. Or, you don't know how to charge a system based on the type of metering device. Or, well, there are many other "or's"
I'm not here trying to get into a pissing match. Does it happen sure, I'm not gonna say it doesn't. It does NOT however, happen as much as apparently you seem to think it does. Are ducts dirty? Yup! That's why you, and every other "entrepreneur" (if you are) out there with a slightly higher than avg, technical IQ try to sell retarded "duct cleaning" services. Do coils get dirty over time? Yup! I get that, and I have seen it also. Almost always in a commercial or industrial atmosphere. My point was that unless the OP, in a residential setting, has some extraordinary, or heavily soiled environment inside his home (cats, dogs, drywall, lives in an actual dust cloud...whatever) it's more likely the air filter
is what would be causing an airflow issue. If there is one (an airflow issue). I'm not throwing out a diagnosis here, simply stating a factual discrepancy in yours. And now I know you are gonna tell us all how you have years of experience and blah blah blah....sure...ok. If that's true...whatever, I'm glad you aren't in a position to attempt to sell anyone I know any of your snake oil. If you don't have any actual HVAC experience, stop trying to google the answer.
Edit: If the AC is short cycling......any good technician would NOT think a "heat anticipator" had anything to do with it.
