NYC NYCHA Thermostat Repairer Examination – Brief Exam Coverage
The NYC NYCHA Thermostat Repairer Examination generally focuses on the knowledge and
practical skills required to install, inspect, troubleshoot, repair, calibrate, and maintain
thermostats and temperature control devices commonly used in residential, institutional, and
public housing heating systems. It also tests safety, tools, electrical basics, control logic, work
orders, and field judgment in occupied buildings.
Main Content Areas Covered
1. Thermostat Fundamentals
2. Heating System Controls
3. Installation and Replacement
4. Troubleshooting and Diagnostics
5. Electrical and Wiring Basics
6. Calibration and Adjustment
7. Safety Practices
8. Work Orders and Field Procedures
9. Preventive Maintenance
10. Practical NYCHA/Building Service Field Judgment
NYC NYCHA Thermostat Repairer Examination – Questions 1–50
1. What is the primary function of a thermostat in a residential heating system?
, Page 2 of 108
A. To increase water pressure in heating pipes
B. To sense room temperature and control the heating system based on the setpoint
C. To regulate electrical service to the entire apartment building
D. To replace the boiler safety controls during cold weather
Answer: B
Rationale: A thermostat monitors room temperature and signals the heating system to operate
when heating is needed.
2. Why is proper thermostat location important for accurate temperature control in an
apartment?
A. It determines boiler fuel type
B. It affects how accurately the thermostat senses the actual room temperature
C. It controls the building’s electrical meter reading
D. It changes the water level inside radiators
Answer: B
Rationale: A thermostat must be located where it can sense representative room temperature
without false influences.

3. Which of the following conditions is most likely to cause a thermostat to give a false room
temperature reading?
A. It is mounted on an interior wall away from drafts
B. It is installed near a radiator, sunny window, or drafty doorway
C. It is connected to low-voltage control wiring
D. It is mounted at normal wall height
Answer: B
Rationale: Heat sources, sunlight, and drafts can distort thermostat readings and cause poor
heating performance.
4. What is the most appropriate first step before replacing a thermostat?
A. Paint the wall behind the thermostat
B. Identify the thermostat type, wiring, and system compatibility
C. Turn the heat all the way up and leave it there
D. Remove all wires without labeling them
Answer: B
Rationale: Before replacement, the technician must understand the existing control type,
wiring, and equipment served.

5. Which tool is most commonly used to check voltage or continuity during thermostat
troubleshooting?
A. Pipe wrench
B. Multimeter
C. Putty knife
D. Caulking gun
Answer: B
Rationale: A multimeter is a standard diagnostic tool for checking voltage, continuity, and
electrical circuit conditions.
6. What is one common sign that a thermostat may not be calling for heat properly?
A. The heating equipment never receives a control signal when the room is cold
B. The thermostat cover is mounted level
C. The apartment windows are closed
D. The radiator has already been painted
Answer: A
Rationale: If the thermostat does not close the control circuit when heat is needed, the system
may not run.
