Duct work runs through attic.

I called out the original hvac company and they took a look and said they saw no water. Foam tubing or fiberglass will work but it s also possible to buy pre insulated 4 duct. You re trying to get warm air to a room and the duct is running through the coldest part of the house. Don t let a contractor talk you into it.

If those dampers can t be accessed from below you ll want to install them close enough to the register so that you can reach them through the register opening. It was new when the ac was put in 7 years ago. It also makes maintenance and or modification easier. Doing so would fill your attic with warm moist air that could rot the.

It s done this way because it s easier and cheaper to run a flex duct through a wide open space than to fit it through and around floor and wall framing. Adding heat runs in a basement may change the airflow in the ductwork going to other rooms. Recently i had another hvac company come out and put in a new bathroom vent and they told me they believed the duct work was full of water. The attic ductwork is flex duct work.

In last week s blog i discussed the practice of burying attic ducts in deep insulation since burying ducts is simply one of several ways to address the energy waste associated with the decision to locate ducts in a vented unconditioned attic it s worth taking a fresh look at all of the possible solutions to the attic duct problem. Install dampers at the registers to adjust airflow. In my experience heating ducts that run through attics cause serious problems in snow country. Each register should have its own damper that can be accessed for adjustment.

Smooth rigid ducts with tape or mastic around all joints will prevent air leakage. Unfortunately this practice is all too common in our northern cold climate putting air conditioning ducts in the hottest. Always insulate the duct to prevent condensation problems as the warm air will be potentially running through cold ductwork. Can i put a vent in the ceiling of the bedroom or must it be in the wall baseboard.
