Preparing Your HVAC for Fall: Maintenance Tips from Heartland Mechanical

Colby Kieffer • September 9, 2025

A Seasonal Checklist for Efficiency and Comfort

As the mornings get cooler and the days grow shorter here in Bellevue, homeowners start to shift their focus from summer air conditioning to cozy fall heating. But before you flip that thermostat over to “heat,” it’s important to make sure your HVAC system is ready. A little seasonal maintenance now can help you avoid unexpected breakdowns, improve efficiency, and keep your home comfortable all season long.


At Heartland Mechanical Contracting, we’ve put together this fall HVAC checklist to guide you through the steps that matter most.


Replace or Clean Air Filters

One of the simplest yet most effective ways to maintain your HVAC system is to replace or clean your air filters. Dirty filters make your furnace work harder, reducing efficiency and lowering your indoor air quality. A fresh filter ensures clean airflow and helps your system perform at its best as the heating season begins.


Test Your Thermostat

Before the first cold snap hits, test your thermostat to make sure it’s working properly. Switch over to heating mode and confirm that the system cycles on and off as it should. If you’re still using a manual thermostat, consider upgrading to a programmable or smart thermostat — it’s a great way to save money on energy bills during the colder months.


Inspect and Clean Vents and Ductwork

Blocked or dirty vents can restrict airflow, leading to uneven heating and higher energy costs. Walk through your home and make sure all vents are open, clear of furniture, and free from dust buildup. If you notice persistent dust or musty odors, it may be time to schedule a professional duct cleaning.


Check the Furnace and Heating Components

Your furnace has been idle all summer, so now’s the time to make sure it’s ready to go. Look for any signs of rust, corrosion, or loose connections. If you hear unusual noises when you turn it on, that’s a red flag worth addressing before winter.


Seal Air Leaks Around the Home

Even the most efficient HVAC system will struggle if your home is leaking warm air. Check for drafts around windows, doors, and attic spaces. Adding weather stripping or caulking can help keep the warm air in and the cold Iowa winds out — improving comfort and reducing heating costs.


Schedule a Professional Tune-Up

Nothing compares to a professional inspection. Our technicians at Heartland Mechanical Contracting perform a full system check: cleaning burners, checking electrical connections, inspecting the heat exchanger, and making sure your furnace is safe and efficient. Annual maintenance not only extends the life of your system but also gives you peace of mind heading into the cold season.


Stay Comfortable All Fall with Heartland Mechanical

A little preparation goes a long way in keeping your home warm and energy-efficient throughout the fall and winter. Whether it’s changing a filter, sealing up leaks, or scheduling your annual furnace check, these steps will help you stay ahead of the season.
