Your Fall Furnace Tune Up Checklist for Garrett Homes

When the crisp autumn air rolls into Garrett and the leaves start turning brilliant shades of orange and red, most of us know it’s time to pull out the sweaters and prep for another Indiana winter. But before the first frost hits DeKalb County, one important task should be at the top of your fall to-do list: a furnace tune up.

Your furnace system works hard all winter to keep your home cozy. Without a little annual furnace maintenance, it can become less efficient, more expensive to run, or even unsafe. T&T Plumbing & Heating, Inc. is here to guide you with a clear, homeowner-friendly checklist that covers the basics you can tackle yourself, along with a few professional steps that are best left to trained technicians.

Why Every Home Needs a Furnace Tune Up This Fall

Garrett winters are no joke. Average temperatures dip well below freezing, with icy winds that sweep through town and long stretches of heavy snow. Residents know that when the season shifts after fall football games at Garrett High School, it’s only a matter of weeks before the cold settles in for good.

A furnace tune up improves comfort, safety, and efficiency. Dust, clogged filters, or a worn-out part can cause higher energy bills, poor indoor air quality, or unexpected breakdowns. Scheduling this regular furnace maintenance in October or early November gives you peace of mind that your system is ready before temperatures fall to their lowest.

Your Fall Furnace Tune Up Checklist

Here’s a practical checklist designed for Garrett homeowners. We’ve broken it into two categories: simple DIY tasks you can handle yourself, and professional services that T&T Plumbing & Heating, Inc. can perform during a regular furnace tune up.

Homeowner DIY Furnace Tune Up Tasks

These steps are quick, safe, and don’t require special tools or training. They’re perfect for preparing your heating system before calling in the professionals.

  1. Change the Air Filter: A fresh air filter is the simplest way to improve furnace efficiency. In most Garrett homes, filters should be replaced every 1–3 months during heating season. A clogged filter restricts airflow, forcing your HVAC system to work harder and wasting energy.
  2. Clear the Vents and Registers: Walk through your home and make sure vents aren’t blocked by furniture, rugs, or curtains; if they are, you may experience uneven heating. Proper airflow helps maintain consistent temperatures in every room, from the cozy living spaces near the Garrett Historic District to newer homes on the edge of town.
  3. Vacuum Around the Furnace: Dust and debris can build up around your furnace. Carefully vacuum the area around the unit to reduce fire hazards and keep the system cleaner overall. Just remember not to open sealed panels—leave the inside cleaning to the experts.
  4. Check the Thermostat: Test your thermostat to make sure it’s working properly. Set it a few degrees higher than the current room temperature and listen for the furnace to kick on. If you have a programmable thermostat, update the schedule for your family’s fall and winter routine.
  5. Inspect Carbon Monoxide Detectors: Furnaces that burn natural gas or propane produce carbon monoxide. Check your detectors to ensure they’re working and replace batteries as needed. This is especially important in older homes like the Mountz House, where historic architecture can come with drafty rooms and older systems.

Professional Furnace Tune Up Services

While homeowners can handle the basics, there are parts of furnace maintenance that require the expertise of a licensed HVAC professional. This is why you need to schedule regular tune ups. Here’s what T&T Plumbing & Heating, Inc. includes in a fall furnace maintenance visit:

  1. Comprehensive System Inspection: A professional HVAC technician technician a full inspection to check for hidden issues with the flame sensor, safety controls, and other components. This includes looking for loose parts, signs of wear, or anything that might turn into a breakdown once the furnace is running daily.
  2. Deep Cleaning the Furnace: Our technicians carefully clean internal components such as the blower assembly, burners, and heat exchanger. This ensures your furnace runs efficiently and safely throughout the coldest months.
  3. Lubricating Moving Parts: A furnace has several mechanical components that need lubrication to avoid wear and tear. Professional tune ups keep these parts working smoothly and extend the life of your system.
  4. Inspecting Electrical Connections: Loose wires or failing connections can cause short circuits or shutdowns. During your furnace tune up, we check every electrical component for safety and performance.
  5. Checking the Heat Exchanger: A cracked heat exchanger can leak dangerous carbon monoxide into your home. This inspection is one of the most important reasons to call in T&T Plumbing & Heating, Inc.
  6. Testing System Performance: After maintenance is complete, our team tests your furnace’s startup cycle, airflow, and overall efficiency. That way, you know it’s running at its best before winter weather hits Garrett.

At the end of your furnace tune up, T&T Plumbing & Heating, Inc. provides you with a complete report of everything we inspected, cleaned, and tested. This report gives you peace of mind by showing exactly what condition your furnace is in, noting any potential concerns, and confirming that your system is ready for the Garrett winter ahead.
