The Donmar guy came to check the AC. Put the Freon check instrument and kept leaking the gas, so that he can say that gas is low and can charge $500 for Freon. The outside unit’s fan motor was bad. The guy said he has to replace the motor and then fill in the gas and total cost will be $800. It sounded fishy to me, why the Freon needs to be refilled if we are not doing anything to the Compressor, Coil or the gas lines? Then we checked with the local store, got the new motor for $120 and replaced it. They guy was trying to fool us by making it a low Freon issue.
