Furnace Maintenance Tips: Preparing Your Heating System for Winter


As colder temperatures settle into Charleston, South Carolina during the winter months, ensuring that your heating system is operating at peak efficiency is crucial to keep your home comfortable and safe. Adequate preparation of your furnace for the season is essential for maintaining its performance, preventing potential breakdowns, and prolonging its lifespan. By taking the time to perform some simple maintenance tasks before the winter begins, you can save on unexpected repair costs, enjoy a more energy-efficient system, and ensure a cozy atmosphere in your home.

Our team at Fix It 24/7 Air Conditioning is here to outline essential furnace maintenance tips that homeowners can follow to prepare their heating systems for winter. While homeowners can do some tasks, it is always recommended to seek our professional assistance for more complex tasks and a thorough inspection of your furnace. Our family-owned and operated, full-service air conditioning, heating, and plumbing business serves Charleston residents and ensures your home stays warm all winter.

Inspect and Change Air Filters

One of the essential furnace maintenance tasks is to inspect and change your air filters regularly. A dirty or clogged filter can restrict airflow, forcing your furnace to work harder to heat your home. This decreases energy efficiency and can lead to potential breakdowns and a shorter system lifespan. As a homeowner, you should routinely check your air filters and replace them as necessary, typically every 1 to 3 months, depending on the type of filter and your household conditions. Choosing a high-quality filter can also help improve your indoor air quality during the winter months when your home is more tightly sealed.

Clean Furnace Components and Ductwork

Keeping your furnace components and ductwork clean is crucial for efficiently operating your heating system. Over time, dust, debris, and pet hair can accumulate on your system’s blower components, burners, and other parts, causing it to work harder and potentially leading to malfunctions. To ensure your furnace runs smoothly, make sure to clean the components thoroughly using a soft-bristle brush or vacuum with a hose attachment. Be careful not to dislodge any wires or connections while cleaning.

Additionally, it’s essential to keep your ductwork clean to maintain good airflow throughout your home. While you may be able to clean some visible registers and vents yourself, hiring our professionals to perform a thorough duct cleaning is often the best way to ensure your entire duct system is free of debris and contaminants.

Check for and Seal Air Leaks

Before the cold weather sets in, inspecting your home for any air leaks that could lead to drafts and reduced energy efficiency is important. Check around windows, doors, and other points of potential air infiltration, such as electrical outlets and ventilation openings. If you find any leaks or gaps, use weatherstripping or caulk to seal them and prevent cold air from entering your home. This simple task can help maintain a comfortable indoor temperature and reduce strain on your heating system.

Test and Calibrate the Thermostat

Your thermostat plays a significant role in maintaining the comfort and efficiency of your heating system. Test your thermostat by setting the temperature a few degrees above the current indoor temperature and observing if the furnace responds accordingly. If your furnace does not turn on or the temperature rises too quickly, you may need to recalibrate or replace the thermostat.

Upgrading to a programmable or smart thermostat can further optimize your home’s energy efficiency by allowing you to set daily temperature schedules according to your needs. This type of thermostat can automatically adjust temperatures when you’re away or asleep, reducing energy usage and saving you money on your energy bills.

Perform a Carbon Monoxide Test

As your furnace operates, it’s necessary to periodically check for any potential carbon monoxide leaks. Carbon monoxide is an odorless, colorless gas that can be deadly if it goes undetected. Ensure your family’s safety during the winter months by installing a carbon monoxide detector near your furnace and living areas. Test the detector monthly and replace the batteries as needed. If your detector alarms or you suspect a leak, immediately turn off your furnace and call our professionals to inspect the system.

Schedule a Professional Inspection and Tune-up

While performing basic maintenance tasks can help keep your furnace in good condition, the best way to ensure optimal performance and safety is to schedule a professional inspection and tune-up at least once a year before the winter season begins. Our experienced technicians can thoroughly examine your furnace, identify any issues or potential problems, and perform necessary adjustments, repairs, or cleaning tasks that may be beyond your expertise.

During a professional tune-up, we will check for proper ignition, ensure the heat exchanger is free of any cracks or damage, clean and adjust burners, lubricate moving parts, inspect and tighten all electrical connections, and verify that safety controls and venting systems are functioning correctlyInvestingng in a professional inspection and tune- lets youan enjoy peace of mind, knowing your furnace is ready to handle the colder months ahead efficiently and safely.
