Fall HVAC Checklists: What to Do Before Winter Arrives

As the leaves change color and temperatures drop, it’s essential to prepare your HVAC system for the winter months. A well-maintained system will ensure your home stays warm and comfortable while also saving on energy costs. Here’s a comprehensive checklist to help you prepare your HVAC system, including mini splits, for the colder season.

1. Inspect and Clean Your Mini Split System

  • Clean the Filters: Remove and clean the air filters in your mini split units. This improves airflow and efficiency.
  • Check the Indoor Unit: Inspect the indoor unit for any dust or debris buildup and clean the coils if necessary.
  • Examine the Outdoor Unit: Clear away leaves, dirt, and other debris from the outdoor condenser unit to ensure proper airflow.

2. Schedule Professional Maintenance

  • Annual HVAC Tune-Up: Consider scheduling a professional inspection for your HVAC system. A technician can check for any issues and ensure everything is functioning properly.
  • Check Refrigerant Levels: Have a professional check the refrigerant levels in your mini split to ensure optimal performance.

3. Test Your Heating System

  • Run the Heating Function: Turn on your mini split’s heating mode to ensure it’s operating correctly before the cold weather sets in.
  • Listen for Unusual Noises: Pay attention to any strange sounds during operation. If you hear anything unusual, contact a technician for an inspection.

4. Seal and Insulate

  • Check for Drafts: Inspect windows and doors for drafts and seal any gaps with weatherstripping or caulking.
  • Insulate Ductwork: If you have ducted heating in your home, ensure that the ducts are properly insulated, especially in unconditioned spaces like attics or basements.

5. Adjust Thermostat Settings

  • Program Your Thermostat: If you have a smart thermostat, program it to optimize your heating schedule for when you’re home and awake.
  • Consider Zoning Options: For mini split systems, utilize zoning features to heat specific areas of your home according to usage.

6. Prepare for Power Outages

  • Check Backup Generators: If you have a backup generator, ensure it’s in working order before winter storms hit.
  • Have Alternative Heating Options Ready: Consider alternative heating methods, such as space heaters, in case of emergencies.

7. Review Safety Features

  • Inspect Carbon Monoxide Detectors: Ensure that carbon monoxide detectors are functioning properly and have fresh batteries.
  • Check Smoke Detectors: Test smoke detectors and replace batteries if needed.

8. Stock Up on Supplies

  • Emergency Kit: Prepare an emergency kit with essentials, including blankets, flashlights, batteries, and non-perishable food in case of winter storms.
  • Heating Supplies: Keep extra filters on hand for your mini splits and any other supplies you may need for maintenance.

9. Assess Your Insulation

  • Check Attic Insulation: Ensure that your attic is properly insulated to keep heat from escaping.
  • Evaluate Wall and Floor Insulation: Assess your home’s overall insulation to maximize energy efficiency.
