For homeowners in Glenview and the surrounding North Shore communities, maintaining an efficient heating system is crucial during our harsh Illinois winters. One of the most overlooked aspects of furnace maintenance is the simple air filter.

Why Air Filters Matter

Your furnace’s air filter plays several critical roles:
• Protecting your furnace’s internal components
• Maintaining indoor air quality
• Ensuring optimal system efficiency
• Preventing unnecessary strain on the system

The Cost of Neglect

When homeowners in Winnetka or Highland Park ignore their air filters, they often face:
• Higher energy bills
• Reduced heating efficiency
• Premature system wear
• More frequent repairs
• Shorter furnace lifespan

How Often Should You Change Your Filter?

The general rule of thumb for filter replacement is:
• Every 30 days for basic fiberglass filters
• Every 60-90 days for pleated filters
• Every 6-12 months for high-end filters

However, factors like pets, allergies, and construction work may require more frequent changes.

The Financial Benefits

Regular filter maintenance can reduce your energy consumption by up to 15%. For the average Northbrook homeowner, this could mean hundreds of dollars in savings over the heating season.
