✅ 10-Point Winter HVAC Checklist
1. Filters & airflow
Clogged filters restrict air movement and force fans to work harder. Clean or replace them to improve comfort and efficiency.
2. Evaporator & condenser coils
Dust and debris on coils reduce heat transfer. A thorough clean can cut running costs and improve performance.
3. Belts, bearings & vibration
Listen for unusual noise. Tighten loose components and lubricate bearings to avoid costly motor damage.
4. Condensate drainage
Blocked drains cause leaks and odours. Check traps and pipework are clear.
5. Electrical safety
Inspect wiring, terminals and insulation. Any heat damage or corrosion should be addressed immediately.
6. Controls & thermostats
Verify correct temperature readings and calibrate sensors. Faulty probes can increase your energy spend by up to 20%.
7. Set-points & schedules
Adjust heating to around 20–21°C and cooling to 23–24°C. Review weekday and holiday settings before peak winter use.
8. Ventilation & air quality
Check airflow rates and cleanliness of AHUs. Good ventilation keeps your workspace healthy and productive.
9. Refrigerant & F-Gas compliance
Look for oil staining or poor performance—signs of a possible leak. Make sure your F-Gas log is up to date.
10. Hygiene & housekeeping
Keep plant rooms tidy, clear debris around outdoor units, and ensure panels and isolators are accessible.
