Problems detected

The ceiling insulation was dusty loose fill fiberglass insulation with different residues potential cause of allergies. The insulation was uneven and the R-value low.

The air barrier of this home was compromised in numerous areas, mainly on the ceiling surface creating pathways for air to move between the attic and the interior of the house.

The air distribution system shows duct leakages. Some of the ducts have been sealed at joints using only tape which easily becomes loose over time causing leakages to occur. The foil surface of the duct board boxes is torn in some areas allowing cold air to escape.

The air conditioning system was performing well, however extra heat loads are placed on the system due to air infiltration through the air barrier of the house and duct leakages causing extra $$ in customer electric bill.
