Winter’s Not Over Yet: How to Keep Your Furnace Running Strong Through the Final Stretch

February might bring thoughts of spring being just around the corner, but here in Ankeny, winter isn’t packing up anytime soon. Iowa’s unpredictable weather means that your furnace still has some heavy lifting to do before the warmer months arrive. The last thing you want is a breakdown when you’re still relying on your heating system to keep your home cozy.

At Obsidian Heating & Cooling, we know that late-winter furnace issues are common—but preventable! Here’s how to keep your furnace running efficiently and reliably through the final stretch of winter.

1. Keep Up with Filter Changes

Your furnace has been working overtime for months now, and its air filter has likely accumulated a hefty amount of dust and debris. A clogged filter restricts airflow, forcing your system to work harder and increasing your energy bills. If you haven’t changed your furnace filter recently, now is the time! We recommend checking your filter at least once a month during peak heating season and replacing it as needed.

2. Don’t Ignore Strange Noises or Short Cycling

By now, you’re probably familiar with how your furnace normally sounds. If you’ve noticed unusual noises—such as banging, rattling, or whistling—it could be a sign of mechanical problems or airflow issues. Similarly, if your furnace turns on and off frequently (short cycling), it may be struggling with overheating, a dirty sensor, or improper sizing. These are warning signs that should not be ignored, as they could lead to a complete system failure. Call Obsidian Heating & Cooling for a professional inspection before the problem worsens.

3. Maintain Proper Airflow Throughout Your Home

Blocked or closed vents can cause your furnace to work harder than necessary, leading to uneven heating and system strain. Walk through your home and make sure all vents are open and unobstructed by furniture, rugs, or curtains. If certain rooms are always colder than others, you may need to have your ductwork inspected for leaks or blockages.

4. Check Your Thermostat Settings

With fluctuating temperatures in February, it’s a good time to reevaluate your thermostat settings. Using a programmable or smart thermostat can help you optimize energy usage by automatically adjusting temperatures when you’re asleep or away from home. Keeping your thermostat set at a consistent temperature (between 68-72°F) can prevent your furnace from overworking and improve overall efficiency.

5. Schedule a Late-Winter Furnace Tune-Up

Many homeowners think they only need to service their furnace in the fall, but a mid-season checkup can be just as important. Your system has been running for months, and wear and tear can start to take its toll. A professional furnace tune-up from Obsidian Heating & Cooling will:

• Inspect and clean key components

• Ensure proper airflow and efficiency

• Identify minor issues before they turn into costly repairs

• Extend the lifespan of your heating system

Regular maintenance can keep your furnace running smoothly and ensure it’s ready to transition to spring without unexpected surprises.

6. Be Prepared for Sudden Temperature Drops

Iowa weather has a mind of its own, and even as we inch closer to spring, another cold snap is always a possibility. Stay prepared by keeping your home insulated and sealing any drafts around windows and doors. This will help maintain consistent indoor temperatures and prevent unnecessary strain on your furnace.

7. Plan Ahead for Your HVAC System’s Spring Transition

While winter isn’t over yet, now is a great time to start thinking about your air conditioning system. Scheduling routine maintenance for your A/C in early spring ensures it’s ready to take over when the time comes. Obsidian Heating & Cooling offers seasonal tune-ups to keep your HVAC system in peak condition year-round.
