How to Prepare Your HVAC System for Fall & Save Money

Get Your Heating & Cooling System Ready for Cooler Weather

As summer fades and cooler temperatures roll in, it’s the perfect time to prepare your HVAC system for fall. A little maintenance now can help you save money on energy bills, prevent costly repairs, and ensure your home stays comfortable all season long.


1. Replace or Clean Your Air Filters

  • Why? Dirty filters restrict airflow, forcing your system to work harder and increasing energy costs.
  • Solution: Change your filter every 1-3 months to maintain efficiency and improve indoor air quality.


2. Schedule an HVAC Maintenance Check

  • Fall is the best time for a professional HVAC tune-up to ensure your furnace or heat pump is ready for the cold.
  • A technician will inspect, clean, and fine-tune your system to catch small issues before they become expensive problems.


3. Check Your Thermostat Settings

  • Lower temperatures mean it's time to adjust your thermostat for energy savings.
  • Consider upgrading to a smart thermostat for automated temperature control and cost savings.


4. Inspect & Seal Air Ducts

  • Leaky or poorly insulated ducts cause energy loss, making your HVAC system work overtime.
  • Fix: Seal leaks with foil tape and ensure all vents are open and unblocked for even heating.


5. Clean Your Outdoor Unit

  • If you have a heat pump, keep the outdoor condenser unit clear of leaves, dirt, and debris.
  • Pro tip: Maintain at least 2 feet of clearance around the unit for better airflow and efficiency.


6. Test Your Heating System

  • Turn on your furnace before temperatures drop to check for strange noises, odors, or performance issues.
  • If you notice anything unusual, schedule a repair before peak heating season begins.


7. Reverse Ceiling Fans for Better Heat Distribution

  • Set your ceiling fans to rotate clockwise in the fall to push warm air down and improve comfort.
  • This simple trick can help you save on heating costs.
