Last-Minute Furnace Fixes: What Chicago Homeowners Need Before the First Cold Snap
A reliable furnace is a necessity during Chicago’s unforgiving winters. Before the chilly season arrives, you want to know that your furnace is up to the challenge. With the help of a few simple DIY checks, you can get your furnace winter-ready.
Discover which maintenance tasks you can perform yourself and when to call in the professionals.
6 DIY Furnace Checks You Can Do Right Now
A furnace check before winter should be part of your cold-weather emergency kit. This proactive approach to heating maintenance ensures your home stays cozy when the snow and ice hit. Try these tips for reliable heating comfort:
1. Test Your Furnace Early
Get ahead of the cold by testing your furnace now. Turn it on and check that it starts smoothly, runs as expected, and shuts down. Pay attention to unusual sounds or smells. If you notice anything strange, call an HVAC professional. Resolving minor issues can prevent major repairs or system failures.
2. Inspect and Replace Air Filters
Dirty or clogged filters reduce airflow, causing your furnace to work harder and use more energy. ENERGY STAR recommends inspecting your air filters monthly, especially during periods of high demand.
Here is a quick breakdown of how to change your furnace filter:
- Turn off the power to the furnace.
- Find the air filter compartment cover near the vent or blower unit.
- Take out the old filter and clean the compartment of any debris.
- For reusable filters, wash the filter with a solution of water and mild detergent and allow it to dry.
- Slide the new disposable or cleaned reusable filter into place, with the arrow pointing toward the blower motor.
- Close the compartment cover and secure it by tightening any clamps or screws.
Switch the furnace back on and test that it works as expected.
3. Clear the Area Around Your Furnace
A clean furnace is a better-working furnace. Beyond being an eyesore, clutter can cause fire hazards and affect efficiency. Remove any flammable materials, debris, or boxes from the area. Keeping the area around the furnace clear is crucial for proper operation and airflow.
4. Examine Your Registers and Vents
Closed or obstructed vents restrict airflow, straining your furnace and causing uneven heating. Open all vents and registers around your home and ensure they’re free of coverings, furniture or dirt that could block airflow. You can also vacuum the vents to remove dust.
5. Test the Thermostat
Confirm your thermostat’s performance by switching from cooling to heating. You should hear the furnace kick in, and the room should warm up. If nothing happens, your thermostat may be faulty.
Try these tips to diagnose the problem:
- Adjust the temperature settings to see if heating activates.
- Check for a tripped circuit breaker or loose wiring.
- Change the batteries in your thermostat and verify that the power is on.
- Compare the thermostat’s readings to a portable indoor thermostat for accuracy.
6. Check Carbon Monoxide Detectors
Gas and oil furnaces produce carbon monoxide (CO). This colorless, odorless gas becomes harmful when it accumulates in the air, and prolonged exposure can lead to carbon monoxide poisoning.
Every home with a gas- or oil-burning furnace should have CO detectors installed. Test these detectors regularly and replace the batteries when needed.
When to Call for Fast Furnace Repair
Some furnace issues need quick, professional attention. If you notice these furnace red flags, call your local HVAC pros:
- Unusual noises: Sounds such as banging, rattling, or screeching are clear warning signs of a problem. The cause could be as simple as loose parts or as serious as a cracked heat exchanger.
- Short-cycling: Overheating, a faulty thermostat, or an oversized furnace can cause frequent on-and-off cycles.
- Uneven heating: If some rooms are toasty and others are freezing, your furnace may be struggling to distribute heat.
- Rising energy bills: Have your heating bills spiked since last winter? An old or inefficient furnace could be the culprit.
- Yellow pilot light: Your pilot light should burn bright blue. A yellow flame indicates a carbon monoxide leak, which needs urgent attention.
- Reduced airflow: Weak air blowing through the vents could mean dirty filters, leaking ducts, or a failing blower motor.
- Strange smells: A slight burning smell can be normal when your furnace first fires up. A lingering or burning plastic smell signals a possible electrical problem. Sulfur or rotten egg odors indicate a gas leak.
- Aging furnace: If your furnace is 15 years or older, it may be time to replace it. Upgrading to a new model can improve energy efficiency and performance.
Why a Professional Heating System Tuneup Is a Smart Move
Regular furnace maintenance ensures safe and dependable heating throughout winter. Here are five reasons why annual service is a good idea:
Prepares You for Winter
A tuneup in the fall sets you up for winter comfort. During a service, technicians lubricate, clean, and test your system for smooth operation. This preventive care reduces the risk of unexpected breakdowns, so you can go into the icy season confident that your home will stay warm when temperatures drop.
Improves Energy Efficiency
A well-tuned furnace requires less power to maintain a comfortable home. With professional maintenance, every part operates at peak efficiency. Reducing energy usage can result in noticeable savings on your utility bills. Even small efficiency improvements add up over a full heating season.
Protects Health and Safety
Professional maintenance includes checks for gas leaks, airflow issues, and faulty electrical components. These inspections help prevent CO risks or fire hazards. A clean, well-maintained furnace also improves indoor air quality. Dust and debris stay out of your living space, creating a healthier environment.
Saves on Repairs
Routine service catches minor issues before they escalate into expensive repairs to avoid emergency callouts and major failures. This proactive approach leads to predictable upkeep instead of costly surprises.
Extends Your Furnace’s Lifespan
Your furnace lasts longer with proper care. Maintenance reduces the strain on its critical parts, helping to prolong its service life. You get more years out of your investment with fewer repairs along the way.
