Columbia, MD 1969 Contemporary Rancher Style
Year Built: 1969
Common Insulation Challenges: Crawl spaces are sometimes too low for treatment, attic areas are inaccessible or filled with storage or HVAC ducts

Unique Features: Often times these homes have large sloped ceilings with lots of recessed lights creating gateways to the outside.
Homeowner Takeaways from this Columbia BGE Energy Audit
The attic areas were under insulated and in needed of specialized treatment, including access cut in one location in order to properly treat the area.
The crawl space had a lot of HVAC ducts that were uninsulated, making encapsulation a smart choice.
A disconnected duct in the attic above the family room was the reason for their comfort problems, not the large window with a nice view!
Long-Term Problems if Left Unchecked
HVAC will have to run much longer shortening lifespan.
Comfort around the home suffers and different areas of the home only get used during certain times of the year.
More room for insect intrusion and other unwanted pests when gateways to the outside from the inside exist.
Higher energy bills that will not amount to better comfort.
Poor decision making on how to fix (buy new HVAC, purchase new windows)
Open crawl spaces that are not properly insulated are huge problems in winter with cold air infiltration and summer with high humidity levels.
Accessing the attic areas in this home required a ladder on the outside of the house.
Uninsulated ducts in an open crawl space is a recipe for high energy bills and low comfort.
Disconnected ducts were a big concern for this home and repairs were sure to make a huge difference.
