The Deep Freeze is Coming: A Traverse City Homeowner's Last-Minute Furnace Checklist
The leaves have fallen, the air has that unmistakable Northern Michigan bite, and “lake-effect” is about to become part of our daily vocabulary. Here in Traverse City, we know what’s coming. That first real deep freeze is just around the corner, and the last sound you want to hear is silence when your furnace is supposed to kick on.
A furnace failure in the middle of a Michigan winter isn’t just an inconvenience; it’s an emergency. The good news is that you can take a few minutes right now to perform some simple, last-minute checks. This quick inspection can give you valuable peace of mind or help you spot a small problem before it becomes a no-heat crisis.
Here’s your last-minute checklist from the experts at Grant Mechanical.
Quick Checks You Can Do Today (DIY Tips)
These are simple, safe tasks anyone can do to ensure your furnace is ready for the work ahead.
- Change Your Air Filter
This is the single most important and easiest thing you can do. A clogged, dirty filter is like forcing your furnace to breathe through a straw. It restricts airflow, makes your system work harder, wastes energy, and can even cause the system to overheat and shut down.
- How to: Locate the filter slot (usually where the main return duct enters the furnace). Slide the old filter out, note the size and the airflow arrow printed on its side. Slide the new filter in, making sure the arrow points toward the furnace.
- Test Your Thermostat
The thermostat is the brain of your heating system. If it’s not working, your furnace won’t get the message to turn on.
- How to: First, if your thermostat uses batteries, replace them. This simple step solves a surprising number of “no-heat” calls.
- Next, turn the thermostat to “Heat” and set the temperature 5-10 degrees warmer than the current room temperature. You should hear a “click,” followed by the furnace kicking on within a minute or two. If nothing happens, you may have a thermostat or a larger system issue.
- Clear the Area Around Your Furnace
Your furnace room or closet often becomes a default storage area. This can be dangerous. Your furnace needs room to “breathe” (draw in air for combustion) and combustibles stored too close are a major fire hazard.
- How to: Remove any boxes, laundry baskets, paint cans, or flammable items from the immediate vicinity. A good rule is to keep at least three feet of clear space around your entire system.
- Check Your Vents and Registers
Your furnace can work perfectly, but if the warm air can’t get into your rooms, you’ll be cold.
- How to: Do a quick walk-through of your home. Make sure all supply vents (where warm air blows out) are open and not blocked by furniture, rugs, or holiday decorations.
- Inspect the Exterior Vents
If you have a modern, high-efficiency furnace, you’ll have one or two (intake and exhaust) white PVC pipes that vent out the side of your house.
- How to: Check these pipes to ensure they are clear of any obstructions. Leaves, bird nests, heavy snow, or ice can block them and cause your furnace to shut down as a safety precaution.
When to Call the Professionals: Red Flags
Your DIY check is a great start, but it doesn’t replace a professional inspection. If you notice any of the following warning signs, it’s time to call a certified HVAC technician.
- Strange Noises: Banging, rattling, or high-pitched squealing are not normal. This can indicate a loose part, a failing motor, or a problem with the blower.
- Odd Smells: A faint burning smell when you first turn it on for the season is common (just dust burning off). However, a persistent smell of burning plastic, or metal, is a major red flag.
- CRITICAL: If you ever smell rotten eggs or sulfur, you could have a natural gas leak. Leave the house immediately, do not use any electronics or light switches, and call your gas utility from a safe distance.
- A Yellow or Flickering Burner Flame: The flame in your furnace should be a steady, consistent blue. A yellow, flickering, or lazy-looking flame can be a sign of poor combustion or a potentially dangerous carbon monoxide issue.
- Frequent Cycling: Does your furnace turn on and off every few minutes? This “short-cycling” is inefficient and puts serious wear and tear on the components.
