     • Cleaning and lubricating moving parts.
     • Testing the thermostat to ensure accurate temperature control.
     • Checking and tightening electrical connections.
     • Inspecting and cleaning the combustion chamber and gas burners.
2. Change Air Filters:
   • Why: Clean filters improve efficiency and indoor air quality.
   • What to Do:
     • Replace or clean air filters every 1-3 months.
     • Consider using high-efficiency filters to capture smaller particles.
3. Inspect and Seal Ductwork:
   • Why: Leaks in ductwork can lead to energy wastage.
   • What to Do:
     • Inspect ducts for visible leaks or gaps.
     • Seal leaks with mastic sealant or metal tape.
     • Consider insulating exposed ducts in unheated areas.
4. Check Insulation:
   • Why: Proper insulation retains heat and reduces energy consumption.
   • What to Do:
     • Inspect insulation in attics, walls, and crawl spaces.
     • Add or replace insulation where needed.
5. Adjust Thermostat Settings:
   • Why: Optimal thermostat settings balance comfort and energy efficiency.
   • What to Do:
     • Set the thermostat to a lower temperature when you're away or asleep.
     • Consider investing in a programmable or smart thermostat for automated adjustments.
6. Consider Zoning Systems:
   • Why: Zoning allows you to control temperatures in different areas of your home.
   • What to Consider:

8. Ensure Proper Ventilation:
   • Why: Proper ventilation is crucial for indoor air quality.
   • What to Do:
     • Use exhaust fans to reduce indoor humidity.
     • Consider installing a heat recovery ventilator (HRV) for fresh air exchange.

By taking these steps, you'll not only keep your HVAC system in peak condition but also ensure a warm and comfortable home throughout the winter season. Stay cozy!
