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.

Check that the thermostat is set to HEAT, not COOL, and that the fan is on AUTO, not ON. With the fan on ON, it blows air between heating cycles. Also common: a clogged filter that makes the furnace overheat and shut off its burners, a failed igniter or flame sensor, or a tripped safety switch. If changing the filter and checking the thermostat doesn’t fix it, call 312-500-4822.

Start with the basics: thermostat batteries and settings, the furnace power switch (it looks like a light switch), the breaker, the gas valve, and whether the blower door is closed tightly, since that door has a safety switch. If all of those are fine, the cause is often a control board, igniter, pressure switch or flame sensor problem, which needs a technician.

The cost depends on the part that failed, the furnace’s age and brand, whether parts are in stock, and the time it takes to diagnose and repair. A flame sensor cleaning costs far less than replacing a blower motor or control board, for example. We diagnose the problem first and give you an upfront quote before any work begins. Call 312-500-4822.

Sometimes. A small repair on a furnace that has been well maintained can still make sense. If the furnace needs a major part like a heat exchanger or blower motor, keeps breaking down, or your gas bills keep going up, replacement is often the better long-term value. We’ll show you both options so you can decide. Thinking about a new system? See our furnace replacement page.

Many common repairs, like igniters, flame sensors, pressure switches and capacitors, can be done in a single visit once the problem is diagnosed. Repairs can take longer when a part has to be ordered, such as a specific control board or blower motor. Your technician will tell you what to expect before starting the work.

Leave the house right away. Don’t flip switches, use your phone indoors, or try to find the leak yourself. Once you’re outside, call Nicor Gas or 911. After the gas utility says it’s safe, call us to inspect and repair the furnace. If your carbon monoxide alarm goes off, take the same steps.

Frequent short cycles usually come from a dirty filter that makes the furnace overheat, a dirty flame sensor, a thermostat that’s badly placed or failing, or a furnace that’s too big for the home. Short cycling wastes energy and wears out parts, so have it checked if changing the filter doesn’t fix it.
