Why should duct heaters be accessible?

Duct heaters should be accessible primarily for maintenance purposes. Ensuring that duct heaters can be easily accessed allows technicians to perform essential tasks such as inspecting, cleaning, repairing, or replacing components as needed. Regular maintenance is crucial to ensure that the duct heaters operate safely and efficiently, preventing potential breakdowns and enhancing the overall performance of the HVAC system. Accessibility supports proper airflow management and reduces the risk of issues that could arise from neglect, such as overheating or component failure, ensuring that the system remains reliable and effective in heating the air distributed throughout a building.
