1970s Colonial with Addition - Fallston, MD
Homeowner Takeaways from their BGE Energy Audit
The attic areas were under insulated and the two crawl spaces were major sources of their comfort problems and high energy bills.
The crawl space had missing insulation, open vents and an ineffective vapor barrier, making encapsulation a smart choice.
A large plumbing chase at the attic floor directly corresponded to an area below that the customer pointed to as particularly uncomfortable was identified as the culprit.
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)
Accessing the attic areas in this home required a ladder on the outside of the house.
Open crawl spaces that are not properly insulated are huge problems in winter with cold air infiltration and summer with high humidity levels.
Disconnected ducts were a big concern for this home and repairs were sure to make a huge difference.
Uninsulated ducts in an open crawl space is a recipe for high energy bills and low comfort.
Overhangs (cantilevers) and open crawl space was a key contributor to this homeowner's comfort problems.
