Mrs. Wrighthood need a second mortgage on her home/business. She had to qualify for the loan and had been told from her real estate agent that her attic air vents needed some work. She called my service company for an emergency repair.

Step 5: Fig.5 shows the real problem, the attic air handler is not connected to the single fiberglass air duct pipe. The picture below shows the spiral air pipe has an fiberglass exterior is completely disconnected from the air handler. All the other duct pipes were connected and there seamed to be no other issues from the duct pipes.

Step 6: Fig.6 shows the duct pipe has a metal cable spiral around the duct pipe. The cable keep the duct pipe open so it does not fall inside the itself. The attic was not well vented, dusty and was over 100 degree Fahrenheit.

Step 7: Fig.7 and fig.8 shows two possibilities to replacing the air handler collar. The possible choices can start at 6 inches to 14 inches, all depending on what size the air duct has been used in the attic. This job required an 8-inchs starting collar.

Step 10: Fig.12 shows that metal duct tape was used to keep the fiberglass duct tape in place to prevent any ac leakage. Once the duct pipe was secured to the air handler the air conditioner was able to pass the cool air to the bedrooms. Now Mrs. Wrighthood has a nice cool home in the Inland Empire.
