Maintain HVAC System for Efficiency and Longevity

Cost Savings

Checklist Tasks

• Replace or clean air filters with proper MERV rating to prevent blower damage.
• Vacuum and clean supply/return vents to improve airflow and system output.
• Clear debris around condenser unit to prevent overheating and compressor failure.
• Flush condensate drain line with vinegar to prevent leaks and mold.
• Verify thermostat calibration using a separate thermometer to avoid over-cycling.
• Tighten electrical connections at control panel to reduce risk of arcing.
• Lubricate blower and motor bearings if accessible to minimize friction.
• Test startup and shutdown cycles to spot any short cycling.
• Inspect ductwork for gaps or loose joints and seal with mastic.
• Clean evaporator and condenser coils with coil cleaner.
• Check refrigerant line insulation for damage or missing sections.
• Listen for unusual noises during operation to catch early component failures.
