As the temperatures in Spokane dip and winter approaches, a reliable furnace becomes essential for maintaining a warm and comfortable home. However, without proper maintenance, furnaces can falter when you need them most. Preparing your heating system before the winter chill sets in can save you from costly repairs and unexpected breakdowns. Here are some essential furnace maintenance and repair tips tailored for Spokane homeowners.

1. Schedule a Professional Inspection

Before winter arrives, have your furnace inspected by a licensed HVAC technician. Regular inspections help identify potential issues like worn-out components, gas leaks, or reduced efficiency. In Spokane, where winters can be harsh, an annual inspection ensures your system operates at peak performance when temperatures plummet.

Key Benefits:

Early detection of problems
Improved energy efficiency
Enhanced system lifespan

2. Replace or Clean the Air Filter

Dirty air filters restrict airflow, making your furnace work harder and less efficiently. During Spokane’s winter months, consider checking your filter monthly and replacing it as needed. Clean filters improve indoor air quality and ensure your furnace operates smoothly.

Pro Tip: Invest in high-efficiency filters to capture more dust, allergens, and pollutants.

3. Test the Thermostat

A malfunctioning thermostat can lead to uneven heating or unnecessarily high energy bills. Test your thermostat to ensure it’s accurate and responsive. If your thermostat is outdated, consider upgrading to a programmable or smart thermostat for greater control over your home’s temperature.

4. Check for Obstructions

Inspect air vents and registers around your home. Ensure they are free of obstructions like furniture, rugs, or debris. Blocked vents force your furnace to work harder, reducing its efficiency and potentially causing wear and tear.

5. Seal Air Leaks

Cold air entering through gaps around doors and windows can overwork your furnace. Use caulk or weatherstripping to seal these leaks, helping your home retain heat and reduce energy consumption.

6. Monitor Furnace Performance

Pay attention to warning signs that your furnace may need repairs, including:

Unusual noises (e.g., banging, squealing, or rattling)
Weak or uneven airflow
A sudden spike in energy bills
Difficulty maintaining a consistent temperature

If you notice any of these issues, contact a professional HVAC technician immediately.

7. Clean and Inspect Furnace Components

Keep your furnace in top shape by cleaning components like the blower motor, burners, and pilot light. For homeowners in Spokane, where debris buildup is common due to dust or ash from wood-burning stoves, this step is critical.

Safety Note: Turn off the power to your furnace before performing any cleaning or maintenance tasks.

8. Ensure Proper Ventilation

Blocked or damaged exhaust vents can lead to carbon monoxide buildup, a serious hazard in enclosed spaces. Check that your vents are clear of snow, debris, or nests that could obstruct airflow. Install carbon monoxide detectors in your home as an added precaution.

9. Consider a Furnace Tune-Up

A professional tune-up can optimize your furnace’s performance. Technicians will clean components, lubricate moving parts, and calibrate the system for efficiency. Spokane winters can be unpredictable, making a tune-up a worthwhile investment for peace of mind.

10. Know When to Replace Your Furnace

If your furnace is over 15 years old or requires frequent repairs, it may be time to consider a replacement. Modern furnaces are far more energy-efficient and can significantly reduce your heating costs.
