It’s that time of year again for Salt Lake City homeowners to start thinking about their furnace maintenance and energy usage!

As the crisp autumn air settles over the Wasatch Front, homeowners in Salt Lake City are preparing for the colder months ahead.
While you might be thinking about cozy blankets and hot chocolate, your furnace is gearing up for its hardest working season of the year. This is exactly why fall months like October and November are the ideal time to focus on furnace maintenance in Salt Lake City, Utah—not just to stay warm, but also to save money on energy bills all winter long.
A well-maintained furnace system doesn’t just provide reliable heat, because it’ll also operate more efficiently, use far less energy, and last a lot longer. And with Utah’s fluctuating winter temperatures and rising utility costs, it’s now never been more important to keep your system in top shape before the first big snowfalls!
1. Schedule A Professional Furnace Maintenance Tune-Up Before Winter Hits
The most effective way to save on heating costs is through a professional furnace maintenance appointment.
During these appointments, the Apex Clean Air technicians will thoroughly inspect your entire system, clean key components, check for safety issues, and make performance adjustments to improve your home’s overall efficiency.
And more specifically, our technicians typically perform the following services during seasonal tune-ups:
- Inspect and clean the burners and heat exchanger
- Replace or clean air filters
- Check gas connections for leaks
- Calibrate the thermostat for accuracy
- Test airflow and system performance
When your furnace is running smoothly, it won’t need to work as hard to heat your home—which subsequently means it’ll use less energy and experience less wear and tear during the coldest days of the winter. Yearly furnace maintenance can also improve your property’s efficiency by up to 20%, according to the U.S. Department of Energy—which makes it one of the most cost-effective ways to lower your monthly bills!
2. Regularly Replace Or Clean Your Furnace Filter
It’s easy to forget about your furnace filter, but this small component plays a huge role in both indoor air quality and efficiency.
A dirty or clogged filter restricts airflow and forces your furnace to work harder to circulate warm air. This not only increases your energy use, but it also puts extra stress on your system and often leads to costly furnace repairs.
In Salt Lake City where dust from Utah’s dry climate and inversion season can build up quickly, it’s recommended to replace your furnace filter every one to three months during heating season. Doing so will go a long way to improve airflow, reduce allergens, and keep your furnace running efficiently all winter!
3. Seal Air Leaks & Improve Home Insulation
Even a perfectly maintained furnace can waste energy if your home leaks warm air. Before temperatures drop, be sure to take time to inspect your windows, doors and ductwork for leaks.
Proper insulation, especially in attics and basements, can further enhance your home’s efficiency. The U.S. Department of Energy estimates that homeowners can save up to 10% annually on heating and cooling costs simply by sealing leaks and improving insulation.
And when paired with professional furnace maintenance, these seemingly small upgrades can dramatically lower energy usage while keeping your home more comfortable.
4. Optimize Your Thermostat Settings
Another easy way to save energy this winter is to adjust your thermostat settings strategically. Lowering the temperature just a few degrees while you’re asleep or away from home can make a noticeable difference on your monthly utility bill.
For most households, setting your thermostat to around 68°F during the day and 60–62°F at night strikes a balance between comfort and efficiency. If you have a programmable or smart thermostat, you can automate these settings for maximum savings without sacrificing warmth.
A properly maintained furnace responds better to thermostat adjustments, which helps ensure consistent heating throughout your home.

5. Keep Vents and Registers Clean and Clear
Blocked or dirty air vents can disrupt airflow and cause uneven heating and wasted energy at your Salt Lake City home.
As part of your fall maintenance routine, our team will be sure to vacuum vents, wipe down registers, and make sure furniture or curtains aren’t obstructing them. If you notice weak airflow or dust blowing out of your vents, it may be time to consider air duct cleaning along with furnace maintenance.
Over time, debris buildup inside ductwork can limit efficiency and recirculate allergens. This is exactly why Apex Clean Air offers both furnace and duct cleaning services, because they’re a perfect combination for improving airflow and indoor air quality!
6. Address Small Furnace Issues Before They Become Big Problems
Fall furnace maintenance also helps you catch potential issues early and well before they escalate into costly repairs or breakdowns during freezing weather. Unusual noises, short cycling, or inconsistent heating may signal worn components or airflow problems.
During your tune-up appointment, our technicians will identify and fix these issues before they cause energy waste or safety risks. This type of proactive maintenance not only saves money on repairs, but it also extends the lifespan of your furnace.
7. Consider Upgrading An Inefficient Furnace
If your furnace is more than 15 years old, even the best maintenance plan may not make it as efficient as today’s high-performance models.
This is because newer furnaces feature energy-efficient technology that uses less fuel to deliver the same comfort. While upgrading can seem like a big expense, the long-term energy savings often offset the initial cost. This is especially the case in regions like Utah where heating demands are high for several months each year.
