Air Con service

Our air con units need to be cleaned. The service guy arrived only with a tank of compress air the size of a small propane tank. And a KFC plastic bag full of his tricks. The air con units were cleaned thoroughly. They are now pumping out cool air like no tomorrow. The cost was RMB230 (CAD$35.50). I couldn't pay that little to get anything cleaned in Regina. The service guy was knowledgeable, polite and only travel with a plastic KFC bag and a tank of compress air. That's his business.
