Dry winter air on the Western Slope pulls more dust and particles into your home. A dirty filter forces the furnace to work harder during the coldest months when daytime highs may stay in the 30s and 40s and nights drop into the teens.

Replace standard filters every 1–3 months during heating season. Higher-MERV filters capture more particles but need more frequent changes. Check the filter monthly and replace it when it looks gray or clogged.

While changing the filter, feel for weak airflow at registers. Restricted airflow can signal dirty ducts, closed dampers, or a failing blower. Sealing obvious duct leaks in accessible areas (basement or crawl space) improves efficiency and comfort.

Cooley’s Heating, Cooling & Plumbing provides filter changes, duct inspections, and full system checks for homes in Delta, Montrose, and Mesa counties. Keep your system breathing freely all winter.

Key Takeaways

• Change filters more often in dry winter conditions.
• Monitor airflow at vents.
• Address restricted airflow early to avoid system strain.
