Fall in southern Minnesota means crisp mornings, colorful leaves, and the reminder that another long winter is right around the corner. Before the snow starts flying, it’s important to make sure your furnace is ready to keep your family safe, warm, and comfortable. At Streitz Heating & Cooling, we recommend scheduling a professional furnace tune-up in Dundas, Northfield, Faribault, and the surrounding areas to avoid costly breakdowns and improve energy efficiency.

Why a Furnace Tune-Up Matters

Many homeowners wait until the first cold snap to turn on their furnace—only to find out it’s struggling, noisy, or not working at all. Regular maintenance solves this by:

• Improving efficiency – A cleaned and calibrated system uses less energy.

• Preventing breakdowns – Catch small issues before they become major repairs.

• Extending lifespan – Well-maintained furnaces last years longer.

• Keeping your family safe – Tune-ups include carbon monoxide and combustion checks.

Fall Furnace Tune-Up Checklist

Here’s what our technicians look at during a professional heating inspection:

• Thermostat & safety controls testing – Ensure accurate temperature readings and proper cycling.

• Heat exchanger inspection – Check for cracks or damage that could lead to dangerous CO leaks.

• Blower motor cleaning – Reduce dust buildup and improve airflow.

• Electrical connections – Tighten and test for safe operation.

• Filter replacement – Swap in a clean filter for better air quality and efficiency.

• Vent system inspection – Confirm flue gases are venting safely outside.

• Carbon monoxide testing – Ensure your system isn’t producing dangerous levels.

Local Tip for Dundas, Northfield & Faribault Homeowners

Minnesota winters are no joke — temperatures often dip well below zero. A furnace failure on a January night can be more than an inconvenience; it can put your home and family at risk. By scheduling service in September or October, you’ll beat the rush and have peace of mind heading into the coldest months.

How to Prepare Before Your Appointment
