Residential Building Inspector Practice Exam

Which of the following is NOT a requirement for installing a new central heating and cooling system?

1. Must have adequate ventilation

2. Must be installed in accordance with approved plans

3. Must not use electricity as a power source

4. Must comply with energy efficiency standards

The correct answer is: Must not use electricity as a power source

Choosing not to use electricity as a power source for a central heating and cooling system is not a requirement based on modern building codes and practices. In fact, many heating and cooling systems, such as electric heat pumps, air conditioners, and electric furnaces, rely on electricity to operate effectively. Central heating and cooling systems can be powered using various sources, including electricity, natural gas, propane, or even renewable energy sources like solar power. It is important for these systems to meet specific installation requirements regarding ventilation, adherence to approved plans, and compliance with energy efficiency standards to ensure safe and efficient operation. However, there is no mandate that they must avoid using electricity entirely, making this choice the correct answer.
