Summary

This blog explains how Western Washington homeowners can improve comfort and air quality in the fall by sealing drafts, balancing humidity, and maintaining HVAC airflow. It covers DIY tips, benefits of professional maintenance, and local seasonal insights to help readers reduce energy costs and protect their heating systems.

Are you feeling cool air even when the heat is on?

As our weather is shifting, it’s vital to maintain efficiency, keep our indoor air quality healthy and continue to have a balanced airflow. We have already experienced cooler temps, rain, and wind, all of which can increase our energy bills.
In this article, learn to keep your home warm, save energy, and ensure your HVAC system performs at its best throughout fall and winter! You’ll learn how sealing leaks, improving ventilation, and cleaning filters can all help.

Why Poor Airflow Will Cost You Money (and Comfort)

Your furnace or heat pump is already working harder due to the days getting shorter and cooler. When your home has cracks that the warm air can escape through, or you have vents that are blocked, it makes it harder for your system to maintain the temperature you enjoy. It’s very common in older Western Washington homes to have gaps around windows, doors, or baseboards. These areas can let in cold air and in turn, push your furnace or heat pump to its limits. If your home has poor ventilation, that can trap humidity and pollutants in your home which can affect your air quality, as well as your comfort.

When you have restricted airflow you’ll experience:

• Uneven temperatures across rooms
• Higher heating bills
• More wear and tear on your system
• Increased risk of HVAC repairs over time

How to Boost Efficiency with Better Airflow and Ventilation

What you will experience when you solve airflow issues:

• Energy Savings:
  • The U.S. Department of Energy estimates that sealing leaks can reduce heating costs by up to 20%.
• Improved Comfort:
  • Balanced airflow eliminates hot and cold spots.
• Longer Equipment Life:
  • Your system won’t have to run as hard to maintain temperature.
• Healthier Air:
  • Cleaner air circulation means less dust, allergens, and humidity buildup.

Even small improvements around your home can help with performance and comfort!

Simple DIY Steps to Improve Airflow

1. Seal Drafts Around Doors and Windows
   Use weatherstripping or caulk to block leaks and prevent warm air from escaping. Don’t forget outlets on exterior walls! You can use foam gaskets help there, too.
2. Keep Vents and Registers Open
   Closing vents can cause pressure imbalances and duct leaks. Instead, make sure vents are open and unobstructed by furniture.
3. Clean Return Air Grilles
   Vacuum grilles regularly and keep at least one foot of clearance to maintain proper air return flow.
4. Reverse Ceiling Fans for Winter
   Set ceiling fans to spin clockwise at low speed—this helps push warm air down without creating drafts.
5. Balance Humidity Levels
   Aim for 30–50% indoor humidity. Too dry? Add a humidifier. Too damp? Run a dehumidifier. Always be sure to run your bathroom fan during and after showers.

When in doubt, call a professional.

Why Professional HVAC Maintenance Matters

A professional HVAC technician can:

• Inspect and clean ducts, coils, and fans to ensure free airflow.
• Test your system for leaks, pressure issues, and efficiency.
• Provide duct cleaning when needed (especially after remodels or if dust or odors are present).
• Help you choose upgrades like an HRV or ERV for fresh air exchange without losing heat.

Professional maintenance also protects your warranty, prevents costly breakdowns, and keeps your heating system ready for the rainy season.

Fall HVAC Tips for Homes in Western Washington

1. Seal up early: Rainy fall weather brings drafts and moisture—caulk and weatherstrip before storms set in.
2. Leverage natural warmth: Open curtains on sunny days to let in heat, then close them at night to retain it.
3. Stay ahead of moisture: Use ventilation fans to prevent mold and mildew from forming in our damp climate.
