✍️ Sample CHI Questions & Answers
1. A home inspector identifies open step flashing where a roof plane meets a sidewall. What is the primary risk of this deficiency?
Open or improperly lapped step flashing creates a direct pathway for wind-driven rain to enter the wall-to-roof junction and damage sheathing, insulation, and interior finishes.
2. Which component of the HVAC system compresses refrigerant gas?
The compressor is a vital part of the HVAC cycle that pressurizes refrigerant and helps move it through the system.
3. Which insulation installation method delivers loose material pneumatically through a hose into attic spaces or enclosed wall cavities?
Blown-in or loose-fill insulation is delivered pneumatically, allowing it to fill irregular spaces and achieve uniform coverage in open attics or enclosed cavities where batts would be difficult to install.
4. When a conflict arises between standard procedures and a unique situation in Tenant Relations & Retention, what should a CHI professional prioritize?
Safety and ethics always take priority in Tenant Relations & Retention. When standard procedures don't adequately address a unique situation, consulting with experienced colleagues or supervisors ensures both safety and professional standards are maintained.
5. Which of the following best describes 'blistering' observed on asphalt shingles during a roof inspection?
Blisters form when moisture or residual solvents vaporize and push up through the shingle mat, creating raised bubbles that rupture and expose the asphalt to accelerated weathering.
6. A home inspector observes that a p-trap under a bathroom sink is installed without a vent pipe. What issue should be documented?
Without proper venting, negative pressure can siphon water out of the p-trap, allowing sewer gases to enter the living space.
