As the days grow shorter and the temperatures begin to dip, most homeowners start to think about what it’ll take to get their heating systems ready for the cool weather ahead. Your furnace will soon be working hard, but is it ready for the job? Taking time now to prepare your system will keep your home comfortable, safe, and energy-efficient all season long. Here are seven must-dos to complete before the cold hits.

1. Schedule Professional Furnace Maintenance
The most important step you can take is to schedule a professional furnace tune-up with our team. A licensed HVAC technician will inspect, clean, and test your system to ensure it runs at peak performance. This reduces the risk of unexpected breakdowns, improves efficiency, and can even extend the life of your furnace.
2. Change or Clean Your Air Filter
Your furnace filter works overtime to trap dust, pollen, and pet dander. A dirty filter restricts airflow, forcing your system to work harder and potentially increasing energy bills. Make it a habit to check your filter monthly and replace it every 1-3 months, or more often if you have pets or allergies.
3. Test Your Thermostat
Before cold weather sets in, test your thermostat to ensure it’s working properly. Turn up the temperature and listen for the furnace to kick on. If the system seems unresponsive, it may be time for a new thermostat. For homeowners looking to save on energy costs, upgrading to a programmable or smart thermostat is a smart investment. These devices can automatically adjust temperatures based on your schedule, keeping you comfortable while cutting down on utility bills.
4. Inspect and Clean Air Vents & Registers
Blocked or dirty vents make it harder for warm air to circulate throughout your home. Take a few minutes to vacuum dust from registers, and make sure furniture, rugs, or drapes aren’t obstructing airflow. Clear vents mean your furnace will run more efficiently and evenly heat your home.
5. Check Carbon Monoxide & Smoke Detectors
Furnaces that burn fuel can produce carbon monoxide (CO), a colorless, odorless gas that’s extremely dangerous. Before the heating season begins, test all CO and smoke detectors in your home. This simple step provides peace of mind and ensures your family is protected from unseen hazards.
6. Check for Air Leaks Around the Home
Even the most efficient furnace can’t overcome a drafty home. Inspect windows, doors, and attic spaces for leaks and seal them with weatherstripping or caulking. Leaky ductwork can also waste a significant amount of heated air before it reaches your living space. By sealing leaks, you reduce energy waste and help your furnace maintain consistent comfort with less effort.
7. Clear the Furnace Area
Your furnace needs space to breathe. Check the area around your unit and remove any clutter, boxes, or flammable materials. A clean, clutter-free furnace area is a simple but often overlooked safety measure.
