Came out averse the customer was concerned about air-flow in one bedroom. After checking the crawl space I found that the supply duct to that room was disconnected and losing all the air onto the crawl space. This is a rental property so the customer will have his landlord give us a call to make the repair. The property manager approved the repair so I went ahead a took care of the issue. I ran the system for 30-40 minutes and the system is according to specifications.
