Is Your Furnace Ready for Michigan Winter? 7 Things Homeowners Should Check in October
As temperatures begin to drop across Southeast Michigan, October is the perfect time to prepare your home's heating system for winter. A little preparation now can help you identify potential problems before the coldest days arrive and ensure your home is ready when you need reliable heat.
Whether you have a gas furnace or another type of heating system, here are seven things you can do this fall to prepare your home for Michigan's winter weather.
1. Check Your Furnace Filter
One of the simplest ways to care for your heating system is to check the air filter regularly. A dirty or clogged filter can restrict airflow, making your furnace work harder to circulate warm air throughout your home.
Before heating season gets into full swing:
Locate your furnace's air filter.
Check for visible dust and buildup.
Replace the filter if it's dirty, following the manufacturer's recommendations for the correct size and type.
Check the filter periodically throughout the heating season.
How often you need to replace your filter depends on the filter type, your home's conditions, pets, and how frequently your system runs. When in doubt, follow the manufacturer's guidance.
2. Test Your Thermostat
Before you rely on your furnace every day, make sure your thermostat is working properly.
Set the thermostat to heating mode and raise the temperature a few degrees above the current room temperature. Your heating system should respond by starting a heating cycle.
If your thermostat uses batteries, check whether they need replacing. Also, make sure the thermostat isn't affected by drafts, direct sunlight, or other factors that could interfere with its temperature readings.
If your furnace doesn't respond, frequently turns on and off, or struggles to maintain the temperature you set, it may be time to have the system inspected by an HVAC professional.
3. Make Sure Your Vents Are Clear
Blocked vents can interfere with proper airflow and make it difficult to maintain consistent temperatures throughout your home.
Walk through each room and check that furniture, curtains, rugs, and other household items aren't blocking supply vents or return-air grilles.
If certain rooms are consistently colder than others, pay attention to when the problem occurs and whether it has changed recently. Uneven heating can have several causes, including airflow restrictions or issues with the heating system.
An HVAC technician can help identify the source of persistent temperature differences.
4. Pay Attention to Unusual Sounds or Smells
Your furnace may make some noise during normal operation, but new or unusual sounds are worth investigating.
Watch for warning signs such as:
Banging or popping: These sounds may indicate an issue with the system or ductwork.
Persistent rattling: Loose components or other mechanical issues may be responsible.
Frequent cycling: A furnace that repeatedly starts and stops may need professional attention.
Unusual burning smells: A dusty odor when you first turn on your furnace for the season can sometimes occur, but persistent or strong odors should not be ignored.
If you smell gas, leave the building without operating electrical switches or using a phone inside. From a safe location, contact your gas utility or emergency services. If a carbon monoxide alarm sounds, get everyone outside immediately and contact emergency services.
Never attempt to repair gas lines, burners, or other internal furnace components yourself.
5. Check Your Smoke and Carbon Monoxide Detectors
Heating season is an excellent reminder to check your home's safety devices.
Make sure smoke alarms and carbon monoxide (CO) alarms are installed in the appropriate locations, functioning properly, and maintained according to the manufacturer's instructions and applicable safety guidance.
Carbon monoxide is an odorless, colorless gas that can be produced by malfunctioning fuel-burning appliances. A properly maintained heating system, combined with working CO alarms, is an important part of keeping your household safe.
If you have a fuel-burning furnace, professional maintenance can help identify potential safety concerns before winter arrives.
6. Check Around Your Outdoor HVAC Equipment
If your home uses a heat pump or another system with outdoor equipment, take a moment to inspect the area around it.
Remove leaves, branches, and other debris that could interfere with airflow. Keep vegetation and stored items away from the equipment according to the manufacturer's clearance recommendations.
Avoid covering equipment unless the manufacturer specifically recommends it. Outdoor heat pumps, in particular, need adequate airflow to operate correctly during cold weather.
If you notice visible damage, unusual operating noises, or persistent ice buildup, contact an HVAC professional rather than attempting repairs yourself.
7. Schedule Professional Furnace Maintenance
Even if your furnace appears to be working normally, an annual professional inspection is an important part of preparing for winter.
During a maintenance visit, a qualified HVAC technician can inspect and service appropriate system components, check operating performance, evaluate safety controls, and identify potential issues that may not be obvious to a homeowner.
Professional maintenance can also help you understand the condition of your current system and whether repairs or future replacement planning may be appropriate.
October is a practical time to schedule service because you can address concerns before your heating system is needed consistently during freezing temperatures.
If your furnace is older, has needed frequent repairs, or struggles to keep your home comfortable, ask your HVAC professional whether additional evaluation is warranted.
