As the vibrant fall colors begin sweeping across the Wasatch Mountains in September and October, Salt Lake City homeowners know all too well how it won’t be long before winter brings its chill and influx of powder days in the Cottonwood Canyons.
But the tough truth is that the inevitable transition from warm summer days to icy nights can often be tough on a Utah household’s HVAC system, which is why the fall season is by far the best time to prepare your heating and cooling equipment.
Here at Apex Clean Air, we’re very proud to be a top-rated HVAC company in Salt Lake City that’s comprised of local specialists who help property owners take a proactive approach toward ensuring efficient, safe and reliable heating system runs all winter long.
If you’re currently wondering how to get started with your winter HVAC preparations, check out our ultimate 2025 fall maintenance checklist detailed in the below sections!
1. Scheduling A Professional HVAC Inspection
The most important step in your fall HVAC checklist is scheduling a professional heating maintenance inspection.
The Apex experts based in Salt Lake City always recommend annual tune-ups before the heating season begins, and one of our licensed technicians will thoroughly examine your furnace or heat pump system, clean all critical HVAC components, test various safety controls, and generally ensure that your home’s system is fully ready to handle the demands of Utah’s winter season.
These types of inspections are also known for identifying many small HVAC issues, including worn belts or dirty burners, long before they turn into expensive breakdowns.
And when keep in mind just how harsh Utah winters tend to be, an inspection is by far the best way to guarantee that your system doesn’t leave you shivering in January!
2. Replacing Or Cleaning Your Air Filters
Air filters play a vital role in keeping your indoor air clean and your HVAC system running efficiently.
During the fall months when leaves, dust and allergens are more prevalent, your filters can clog far more quickly as compared to other seasons. This is problematic because a clogged filter subsequently forces your furnace to work much harder than it’s actually supposed to, which increases energy bills and shortens the lifespan of the unit.
This is why our experts recommend replacing disposable filters every 1–3 months or cleaning reusable ones even more regularly. This simple maintenance step can significantly improve airflow and indoor air quality in your home this winter!
3. Cleaning & Inspecting Air Ducts
If your home’s ducts or vents are blocked with dust, pet hair or debris, your HVAC system is likely going to struggle to evenly distribute heat throughout your property. Fall just so happens to be a great time to vacuum vents, remove obstructions, and schedule professional air duct cleaning appointments as needed.
Our technicians often see homeowners overlook their ductwork; however, keeping your ducts clean can go a long way to improve efficiency, reduce allergens, and help your system work more effectively when the coldest months hit.
4. Testing Your HVAC System’s Thermostat
Your thermostat is essentially like the brain of your entire HVAC system, and the fall months like September and October are the perfect times to test your thermostat prior to heavily relying on it in the winter.
Be sure to set your thermostat to heat mode and check to see if your furnace kicks on properly. If you notice any delays, strange noises or uneven heating, it’ll be important that you schedule an HVAC system inspection with the Apex team this fall.
And it’s no secret anymore how a lot of HVAC experts in Salt Lake City are also now recommending smart thermostat upgrades. These smart systems are capable of allowing you to program heating schedules and monitor energy use, which can lead to significant savings on your winter heating bills!
5. Inspecting Your Furnace Flame & Pilot Light
For homes with older gas furnaces, checking the pilot light or burner flame is another important fall checklist task.
A healthy furnace flame should be steady and blue, so a yellow or flickering flame might subsequently indicate incomplete combustion—which is a serious safety hazard. If you’re currently noticing any pilot light irregularities, be sure to call us immediately to inspect the system.
And if your Salt Lake City home features a modern furnace with electronic ignition, you’ll still greatly benefit from professional inspections to ensure that your system’s burners are clean and operating safely.
6. Sealing Air Leaks Around Your SLC Home
Your HVAC system will always work harder when your home is losing warm air, which is why it’s imperative check for air leaks around windows, doors and duct connections before winter arrives.
You should also consider applying weather stripping or caulking to seal any gaps and improve your home’s energy efficiency this upcoming winter.
This is why our heating maintenance inspections always include home efficiency checks to help you maximize the performance of your furnace—while also lowering your energy bills!
7. Checking Carbon Monoxide & Smoke Detectors
With furnaces running more frequently in the fall and winter, safety should be your top priority.
Our Salt Lake City HVAC experts always stress the importance of checking and replacing batteries in carbon monoxide and smoke detectors, because although a well-maintained HVAC system is safe, these detectors provide an extra layer of protection for your household.
8. Clearing The Area Around Your Furnace
Many homeowners unintentionally store boxes, tools or cleaning supplies near their furnace unit.
For safety and performance purposes, it’s best to keep the area around your heating unit clear of any debris.
Proper airflow is essential, and reducing clutter around the furnace will help minimize fire hazard—while making it easier for technicians to perform maintenance inspections.
9. Preparing Your Outdoor Unit
If you have a heat pump or central AC unit outside your home, fall is the time to prepare it for winter.
This will include clearing away leaves, dirt and debris from around the unit.
Some Utah homeowners will also place a breathable cover over their AC unit to protect it from snow and ice buildup, so if you plan on doing this, just make sure that the cover allows airflow to prevent moisture damages.
10. Scheduling Any Needed Furnace Repairs Or Upgrades
If your HVAC system struggled last winter or showed signs of aging during the summer, fall is the time to address furnace repairs or consider furnace installation upgrades.
We also often offer seasonal promotions in the fall, which makes it more affordable to replace worn-out furnaces or install high-efficiency systems before the coldest months arrive!
