I just saved a fixing my FB4ANF048000AFAA Carrier central

I just saved a bundle fixing my FB4ANF048000AFAA Carrier central A/C using JA! It was the first problem with system for several years, otherwise, it just works. What maintenance should I do? I have seen the spray foam cleaner for the coils, is that a good idea? It cools ok, but should I have coolant checked or can I do it reasonably? I would have to buy equipment, I guess, is that a good investment? Lastly, I have never had ducting cleaned in 13 years, is that worth it? Several questions, I know, generally, can I do preventive maintenance myself or is it worth the fee for a professional to do it?

Sure! My FB4ANF048000AFAA Carrier fan quit blowing for A/C.

Sure! My FB4ANF048000AFAA Carrier fan quit blowing for A/C. It will blow if I turn the heater on. The outside unit runs and the coils quickly freeze up with no blower, so it's ok. With A/C, fan blow when set on auto or fan. Any ideas?JA: Did you double-check the thermostat? And what about the unit's filters?Customer: I figure the thermostat simplay says 'Run A/C' when appropriate, so my guess something wrong with blower unit. My guess is a thermostat that keeps fan blowing after turning air off to clear out blower unit and vents, what do you think?JA: Do you plan on doing the work yourself?Customer: Yes, if it simply replacing a part, if I can diagnose problem.JA: Anything else we should know to help you best?Customer: No
