Is Your Furnace or Boiler Ready for Fall? October Maintenance Tips

As the leaves start to fall and cooler air rolls into Chicagoland, it is the perfect time to ask yourself—is your furnace or boiler ready for the season ahead? At Doornbos Heating & Air Conditioning, we have been helping families and businesses in the South suburbs prepare their heating systems since 1927. We know how quickly Illinois weather can change, and the last thing anyone wants is to be caught off guard when temperatures drop.

Whether you have a gas furnace or boiler system, a little maintenance in October can go a long way toward keeping your space warm, safe, and energy efficient. Let’s take a closer look at what you can do now to avoid issues later.

Why Fall Maintenance Is So Important

A lot can happen between heating seasons. Dust and debris can build up, parts can wear out, and minor issues can turn into costly breakdowns. Annual boiler maintenance and gas furnace tune-ups help catch these problems early. Not only can this save you money, but it also gives you peace of mind knowing your system is running safely and efficiently.

In fact, many manufacturer warranties require routine maintenance to stay valid—so skipping your fall tune-up could cost you down the line.

Gas Furnace: October Maintenance Checklist

If your home or business uses a gas furnace, here are some key steps to take this fall:

1. Change the Air Filter

This simple step often gets overlooked, but it plays a huge role in keeping your system running smoothly. A clogged filter restricts airflow, making your furnace work harder and increasing energy costs. We recommend checking your filter monthly and replacing it at least every 1-3 months during the heating season.

2. Test the Thermostat

Before the cold hits, switch your thermostat over to “heat” mode and make sure it responds correctly. If your furnace doesn’t kick on or it takes a long time to heat up, it might be time for a checkup.

3. Listen for Unusual Noises

Grinding, banging, or rattling sounds are not normal. These noises could signal a loose part or a more serious mechanical issue. Don’t ignore them—call us for an inspection.

4. Schedule a Professional Inspection

A qualified HVAC technician from Doornbos can clean internal components, check for gas leaks, inspect heat exchangers, and test safety controls. Our technicians are trained to spot even small problems before they become big headaches.

Boiler Maintenance Tips for Fall

Boilers tend to be extremely durable, but that doesn’t mean they are maintenance-free. Regular boiler maintenance can help prevent breakdowns and increase system lifespan.

1. Check the Pressure Gauge

Boilers operate within a set pressure range. If the pressure is too low or too high, it could affect heating performance. If you’re unsure how to check this safely, our team can assist.

2. Bleed Radiators (If Needed)

If your home has radiators, you might notice cold spots or uneven heating. Air can get trapped inside, and bleeding the radiators can solve the issue. It’s a quick fix, but you’ll want to follow safety instructions—or leave it to the pros.

3. Inspect for Leaks

Water around your boiler, rust, or damp areas near pipes could indicate a leak. Addressing this early can help you avoid water damage or total system failure.

4. Schedule a Fall Tune-Up

Like gas furnaces, boilers benefit from yearly inspections. At Doornbos, we check for corrosion, test burners, clean components, and ensure everything is operating safely and efficiently.

Don’t Forget Commercial Properties!

If you own or manage a commercial building in the Chicagoland area, now is the ideal time to schedule maintenance for your heating system. Commercial boiler maintenance and gas furnace care is just as critical—and often more complex—than residential systems. Our team has trusted partners that can assist you with professionalism, precision, and care.
