So, mine wasn’t working very well, just barely keeping up & I cleaned the filter which was way overdue for a cleaning. Much better. But it got me thinking. Energy use of an AC is related to the amount of heat that it extracts from the air that passes through it. So a clogged filter means reduced air flow and much less energy used. Sigh.
Interesting, though, everything out there on the internet says the opposite i.e. that changing your filters will reduce your bill. Not buying that sales pitch. It violates thermodynamics. It does make things cooler, though.
