Home inspection Exam (HVAC) part 1
Questions with Complete Solutions
(Latest 2025)
In a forced air system with a central air conditioning system
installed, humidity is reduced by
running the humidifier in reverse.
condensation at the condensing coil
condensation at the evaporator coil
condensation at the compressor - Correct Answers
✅Condensation at the evaporator coil
The evaporator coil is cold, below the dew point so when
humid room air hits the coil two things happen. First the
humidity falls out of the coil on contact. Second the air
passing through the coil gives up heat which is absorbed by
the refrigerant material.
What is the most likely result of insufficient air flow across the
evaporator coil?
