1. Document Objective
This guide outlines the standard procedures for transitioning the building-wide heating, ventilation, and air conditioning (HVAC) systems between seasons. Following this timeline ensures resident comfort, system efficiency, and compliance with local housing bylaws. [1]

2. Spring Transition (Switching to Cooling)

• Target Timeline: Mid-to-late Spring (or when outdoor temperatures consistently exceed 21°C / 70°F). [1]
• Core Tasks:
  • Deactivate the central heating boilers and close primary steam or hot water valves.
  • Power on the central cooling towers or chillers and run diagnostic tests.
  • Inspect and replace air filters in all common area ventilation systems. [1]
• Staff Protocol: Update the resident portal to notify tenants of the exact week the cooling system will become active.

3. Autumn Transition (Switching to Heating)

• Target Timeline: Early Autumn (or when outdoor temperatures consistently drop below 15°C / 59°F). [1]
• Core Tasks:
  • Shut down and safely drain the outdoor cooling towers to prevent winter freezing.
  • Fire up the central heating boilers and verify that all safety relief valves operate correctly.
  • Bleed air from the main loop lines to ensure even heat distribution across all floors. [1]
• Staff Protocol: Remind residents via the portal to clear any items blocking the vents or baseboards inside their apartments.

4. Year-Round Efficiency Checks

• Thermostat Calibration: Verify that central thermostats in lobbies and hallways are locked and set to energy-saving baseline targets.
• Exhaust Systems: Clean the building's central roof exhaust fans quarterly to maintain proper air circulation throughout the building.
