deficiencies. Where would these be most likely to occur?
, a. Window heads
b. The center of large expanses of EIFS
c. Along the bottom edge of the EIFS installation

An inspector notes that the heat pump is not functioning and that the condensate
pan under the air handler is full of water. Why might these two things be related?
a. The full condensate pan tripped a condensate overflow switch. The unit turned off
in order to ensure that condensate did not spill.
b. The full condensate pan indicates that the fan in the air handler is not functioning,
as it should.
c. The full condensate pan indicates that there is a leak in the heat exchanger, which
has depressurized the unit, causing it to turn off.
d. The full condensate pan means that combustion byproducts have condensed and
are flowing back into the house through the flue. This tripped the flue gas spill switch,
turning the unit off. ANS:- The full condensate pan tripped a condensate overflow
switch. The unit turned off in order to ensure that condensate did not spill.
