Creating a Year-Round HVAC Maintenance Plan

Step 1: Inventory and Documentation

Start by compiling a detailed inventory of all HVAC equipment, including:

• Model and serial numbers
• Installation dates and warranty info
• Manufacturer’s recommended maintenance schedule
• Filter and belt sizes/types

Keep this information in an accessible location for staff and service technicians. Digital facility management tools can streamline record-keeping and reminders.

Step 2: Establish a Preventive Maintenance Schedule

Preventive maintenance is best divided into monthly, quarterly, and seasonal tasks. Align your plan with warranty requirements and local climate conditions. Coordinate with a certified HVAC contractor for inspections, tune-ups, and repairs beyond your staff’s expertise.

Step 3: Assign Responsibilities

Clearly define which tasks are handled by in-house staff (e.g., filter changes, visual checks) and which require professionals (e.g., refrigerant checks, electrical diagnostics). Assign a point person to oversee compliance and log completed tasks.

Monthly and Quarterly HVAC Maintenance Tasks

Monthly Tasks

• Inspect and Replace Air Filters: Dirty filters restrict airflow and overwork the system. Replace or clean filters every 30 days, or as needed in dusty environments.
• Check Thermostats and Controls: Test for accurate temperature/humidity readings and adjust settings for seasonal needs.
• Look for Visible Leaks or Blockages: Inspect for water drips, refrigerant leaks, or blocked vents and report issues immediately.

Quarterly Tasks

• Clean Condenser and Evaporator Coils: Dirty coils hinder efficiency. Schedule professional cleaning if needed.
• Lubricate Moving Parts: Motors, fans, and bearings require lubrication to reduce friction and wear.
• Test System Safety Controls: Ensure all safety shutoffs and alarms function properly.
• Inspect Drain Lines and Pans: Clear any clogs to prevent water damage or mold growth.

Seasonal HVAC Maintenance: What to Prioritize
