Preparing Your Heating System for the Fall: A Checklist

As the crisp autumn air begins to settle in Cheyenne, Wyoming, it's time to start thinking about your home’s heating system. Ensuring that your heating system is ready for the cold months ahead is crucial for staying comfortable and avoiding unexpected breakdowns. At Marv's Plumbing & Heating, we’ve put together a comprehensive checklist to help you prepare your heating system for fall and ensure it runs efficiently all winter long.

1. Schedule a Professional Inspection

Before the temperatures drop, it’s wise to have a professional HVAC technician inspect your heating system. A thorough inspection can identify potential issues before they become costly repairs. At Marv's Plumbing & Heating, our experienced technicians can assess your system, make necessary adjustments, and provide recommendations to keep everything running smoothly.

Key Points:

  • Check for any signs of wear and tear.

  • Inspect and clean burners and heat exchangers.

  • Test the system's overall efficiency and safety.

2. Replace or Clean Air Filters

Clean air filters are essential for your heating system's efficiency and air quality. Dirty filters restrict airflow, causing your system to work harder and potentially leading to higher energy bills. It’s recommended to replace or clean your filters at the start of the fall season and then check them monthly throughout the winter.

Key Points:

  • Replace disposable filters or clean reusable ones.

  • Consider upgrading to high-efficiency filters for better air quality.

  • Mark your calendar for regular filter checks and replacements.

3. Check and Seal Ductwork

Leaky ducts can result in significant heat loss, leading to higher energy costs and uneven heating in your home. Before you start using your heating system regularly, take the time to inspect your ductwork for any visible leaks or loose connections. Sealing these leaks with duct tape or mastic sealant can improve your system's efficiency.

Key Points:

  • Inspect duct joints for leaks or gaps.

  • Seal any leaks with appropriate materials.

  • Consider professional duct cleaning if there’s significant dust buildup.

4. Test Your Thermostat

Your thermostat plays a crucial role in maintaining a comfortable temperature in your home. As part of your fall heating system preparation, test your thermostat to ensure it’s functioning correctly. If you’re still using a manual thermostat, consider upgrading to a programmable or smart thermostat for better control and energy savings.

Key Points:

  • Test the thermostat to ensure it responds correctly.

  • Calibrate the thermostat if necessary.

  • Upgrade to a programmable or smart thermostat for improved efficiency.

5. Inspect and Clean Vents and Registers

Blocked or dirty vents and registers can restrict airflow and make your heating system work harder than necessary. Before firing up your system for the season, take the time to inspect all vents and registers in your home. Make sure they are clean, open, and free from obstructions like furniture, curtains, or rugs.

Key Points:

  • Vacuum vents and registers to remove dust and debris.

  • Ensure all vents are open and unobstructed.

  • Consider installing vent covers with built-in filters for improved air quality.

6. Test Carbon Monoxide Detectors

A properly functioning heating system is crucial for safety, especially when it comes to preventing carbon monoxide (CO) leaks. Make sure your carbon monoxide detectors are in good working order by testing them before the heating season begins. Replace batteries as needed, and consider installing additional detectors if your home lacks adequate coverage.

Key Points:

  • Test each carbon monoxide detector in your home.

  • Replace batteries or units that are not functioning properly.

  • Install additional detectors in key areas like bedrooms and near the heating system.

7. Inspect the Chimney and Flue (If Applicable)

If your heating system includes a furnace or boiler that vents through a chimney or flue, it’s important to have these inspected before the cold weather sets in. Over time, chimneys can accumulate soot, debris, or even animal nests, which can block proper ventilation and create safety hazards.

Key Points:

  • Have a professional inspect and clean the chimney or flue.

  • Ensure there are no blockages or damage that could impede airflow.

  • Install a chimney cap to prevent debris or animals from entering.

8. Bleed Radiators and Check for Air in the System (For Radiator Systems)

If your home uses a radiator heating system, you may need to bleed the radiators to remove trapped air. Air in the system can prevent radiators from heating up properly and reduce the overall efficiency of your heating system.

Key Points:

  • Bleed each radiator to remove trapped air.

  • Check for any cold spots on the radiators after bleeding.

  • Ensure the boiler pressure is correct after bleeding radiators.

9. Check Insulation Around Pipes and Water Heater

Proper insulation around pipes and your water heater is essential to prevent heat loss and avoid frozen pipes in the colder months. Inspect the insulation around any exposed pipes, especially those in unheated areas like the basement, attic, or garage.

Key Points:

  • Add insulation to exposed pipes in unheated areas.

  • Check the insulation blanket around your water heater.

  • Consider upgrading insulation for better energy efficiency.

10. Stock Up on Emergency Supplies

Even with the best preparation, Wyoming’s harsh winters can bring unexpected challenges. Ensure you have a stockpile of emergency supplies in case of a heating system failure or power outage. This includes space heaters, blankets, and backup batteries for your thermostat and detectors.

Key Points:

  • Keep space heaters and blankets accessible.

  • Stock up on batteries for thermostats and detectors.

  • Have a plan in place for heating your home during an emergency.


Preparing your heating system for the fall is an essential step in ensuring a warm and comfortable home throughout the winter. By following this checklist, you can help prevent unexpected breakdowns, improve your system’s efficiency, and keep your energy bills in check.
