How Often Should You Service Your Furnace in Seattle?

Seattle winters can be damp, chilly, and unpredictable—making your furnace one of the hardest-working systems in your home. One of the most common questions homeowners ask us at Black Lotus HVAC is: “How often should I service my furnace?”

The short answer: once a year—ideally in early fall before the first real cold snap hits.

Why Annual Furnace Maintenance Is Essential

• Efficiency: A tuned furnace uses less fuel and keeps energy bills lower.

• Safety: Professional inspections detect gas leaks, carbon monoxide risks, or faulty wiring.

• Longevity: Regular maintenance prevents small issues from becoming expensive breakdowns.

Seattle-Specific Consideration

The Pacific Northwest’s damp climate can cause more dust and moisture buildup than in drier regions. That makes annual furnace service even more critical here.

Think of furnace maintenance like an oil change for your car—skip it, and you’re gambling with your comfort and safety. Scheduling service before winter ensures efficiency, reliability, and peace of mind.
