As the first day of December arrives, it’s the perfect time for Philadelphia homeowners to ensure their HVAC systems are ready for the colder months ahead. With the temperatures dropping and winter in full swing soon, here are some HVAC-related things to consider on December 1st to keep your home warm and efficient all season long.

1. Schedule a Furnace Check-Up

Philadelphia winters can be unforgiving, and a well-maintained furnace is crucial to stay cozy. If you haven’t already, schedule a professional tune-up to ensure your system is running efficiently and safely.

  • Why Now: Catching minor issues early can prevent costly breakdowns during the coldest weeks of winter.

2. Replace Your Air Filters

Fresh filters help your HVAC system run more efficiently and improve indoor air quality—a must during the holiday season when homes are filled with guests, cooking smells, and decorations.

  • Pro Tip: Aim to change filters every 1-3 months, especially in the winter when your system works harder.

3. Check Your Thermostat Settings

Optimize your thermostat for the season by setting it to a consistent, energy-efficient temperature. For Philly residents, a programmable or smart thermostat can help manage fluctuating temperatures and reduce heating costs.

  • Suggested Settings: Keep your home at 68°F when you’re home and lower it by 5-8°F at night or when you’re out.

4. Seal Windows and Doors

Drafts are your HVAC system’s worst enemy, forcing it to work harder and increasing energy bills. December 1st is a great time to inspect your windows and doors for drafts and seal them with weatherstripping or caulk.

  • Local Tip: Philly’s older row homes and historic properties often have drafty spots—pay special attention to these areas.

5. Inspect and Clear Vents

Ensure all supply and return vents are free of obstructions like furniture, rugs, or holiday decorations. Blocked vents reduce airflow, making your HVAC system less efficient.

  • Bonus: Clean vent covers and surrounding areas to improve air quality and circulation.

6. Prepare for Holiday Gatherings

If you’re hosting holiday dinners or parties, your HVAC system will face extra demands from added guests and kitchen activity. Ensure it’s ready to handle the load by keeping filters clean and air circulating.

  • Fun Fact: Cooking and large gatherings can raise indoor temperatures, so consider adjusting your thermostat to save energy.

7. Plan for Unexpected Winter Weather

December can bring unpredictable cold snaps to Philadelphia. Ensure your HVAC system is ready by checking:

  • Your furnace’s emergency shut-off switch.
  • Backup heating options like portable heaters (ensure they’re safe and functional).
  • Your HVAC system’s outdoor components, clearing away leaves or debris to prevent ice buildup.

8. Upgrade Your System if Necessary

If your heating system has been unreliable or inefficient, December is an excellent time to explore options like a dual-fuel heat pump or high-efficiency furnace. These upgrades can handle Philly’s winter weather while reducing your energy bills.

9. Check Humidity Levels

Cold air can make your home feel dry and uncomfortable. Consider adding a humidifier to your HVAC system to maintain comfortable humidity levels, which can also reduce static electricity and keep your skin from drying out.

10. Consider Your Energy Bills

Philly winters can spike heating costs, but efficient HVAC habits can keep your bills manageable. Take advantage of PECO’s energy-saving programs or rebates on high-efficiency HVAC upgrades.
