Disposable furnace filters should be checked monthly and changed every one to three months depending on use and manufacturer recommendations. Washable filters need the same frequent inspection; clean them thoroughly and allow them to dry before reinstalling. Regular filter maintenance helps your furnace run efficiently and prevents issues that might require heating repair.

Homeowners should have an HVAC professional perform a tune‑up on your furnace at least once a year, ideally in the fall before the heating season. Annual service keeps your furnace safe, efficient and ready for Chicago winters. Older systems or those that work hard all year may benefit from more frequent inspections.

Watch for inconsistent heat, sudden spikes in energy bills, unusual smells, or loud noises like rattling or banging. Frequent on‑off cycles (short cycling) and pilot light problems can also indicate trouble. If you notice any of these, schedule a heating repair promptly to prevent bigger issues.

A mild burning scent when you first turn on the heat is usually dust burning off and should fade within a few hours. Persistent smells can signal clogged filters causing the blower motor to overheat, debris trapped in the system, or even damaged wiring. If the odor doesn’t dissipate or smells like gunpowder, rotten eggs or burning plastic, shut off the furnace and call a licensed HVAC repair technician.

Whistling often points to air leaks in ductwork, while a high‑pitched squeal usually means fan belts need lubrication. Scraping or grinding can indicate loose parts or a failing blower motor. A loud bang after the furnace starts may be gas igniting after a delay. Shut off the system and arrange for immediate furnace repair if you hear this.

With regular maintenance, most forced‑air furnaces last 15-20 years. When your system approaches 15 years old, efficiency can decline, so it’s wise to start budgeting for replacement and consider a high‑efficiency upgrade.

Homeowners can handle basic tasks like changing filters or checking thermostat batteries, but most furnace repairs should be left to certified professionals. A malfunction could involve gas lines, electrical components or safety switches. Attempting DIY repairs can be dangerous; when in doubt, call a qualified HVAC technician.

Regularly replace or clean filters, keep vents and return ducts clear, and ensure your thermostat is working properly. Schedule annual professional maintenance to clean burners, inspect the heat exchanger and adjust gas valves. Clearing debris around the unit and sealing leaky ducts will also help your heating system run more efficiently, reducing the need for costly repairs down the road.
