Homes Built Between 1980 and 1989

1980 to 1989 home review

During a heat ducting exam for homes built between 1980 and 1989, The Ductologist may find these problems:

Poorly designed ducts

As the number of new homes increased rapidly, the builders had to be quick with the construction. This lead to a one-size-fits all approach to duct design. We can make adjustments and dramatically improve air distribution.

Metal ducts with poor connections

Metal to metal duct connections were often slipped together and "sealed" with duct tape. They should be fastened with screws and sealed with Mastic.

Broken or disconnected ducts

We find ducts that are completely disconnected. They need to be reattached and permanently secured and sealed.

Flex ducts with poor connections

In the 1980s, flexible ducts became commonplace because of their economy and ease of install. Often these were held together with tape that fails very quickly, or not secured well and pull apart. We can fasten them properly.

Insufficient or missing insulation on the ducts

Ducts should have 2 inches of insulation to achieve and R-value of 8 or better.

Insufficient or missing insulation for the floors and attic

Insulation is what keeps the heat energy in the home. Many homes of this era have less than required insulation.

Building cavities used as ducts

"Ducts" made from closing a wooden structure were common practice until recently. They leak a great deal of air to and from the outside of the home.
