Michigan winters are no joke. With temperatures often dipping well below freezing, your HVAC system becomes the heart of your home. A breakdown in the middle of January in Howell or Brighton isn’t just uncomfortable—it can be dangerous. That’s why preparing your HVAC system for winter is one of the smartest steps Michigan homeowners and businesses can take.
At Oak Grove Heating and Cooling, LLC, we specialize in helping local residents with reliable heating repair and HVAC maintenance to keep their homes warm and energy-efficient all season long. Below, we’ll walk you through practical steps to ensure your heating system is ready to face Michigan’s coldest months.
1. Schedule a Professional HVAC Inspection
Before winter sets in, the best thing you can do is schedule a heating system inspection with a trusted local HVAC company. A professional technician will:
- Check for worn-out parts or leaks
- Test the furnace or heating system for proper operation
- Ensure the thermostat is calibrated correctly
- Inspect electrical connections and safety controls
- Verify that your system is operating at peak efficiency
This simple step can prevent costly breakdowns and extend the lifespan of your furnace.
2. Replace or Clean Your Air Filters
A clogged filter makes your furnace work harder, driving up energy bills and lowering air quality. Michigan homeowners should replace filters every 1–3 months, especially during heavy usage in winter.
Benefits of clean filters include:
- Better airflow
- Improved indoor air quality
- Lower energy consumption
- Less strain on your HVAC system
3. Check and Seal Air Leaks
Drafty windows and doors can cause your furnace to run constantly. Before the cold sets in:
- Inspect windows, doors, and attic spaces for air leaks
- Seal gaps with weatherstripping or caulk
- Add insulation where needed
Not only will this keep your home warmer, but it also reduces your HVAC system’s workload.
4. Test Your Thermostat
Your thermostat controls comfort and efficiency. Take a few minutes to:
- Switch from cooling to heating mode
- Program a winter schedule (lower temps while away or sleeping, warmer temps during mornings and evenings)
- Consider upgrading to a smart thermostat for maximum efficiency
Michigan’s fluctuating temperatures make programmable or smart thermostats especially valuable.
5. Clean and Inspect Vents & Ducts
Blocked vents and dirty ducts can cause uneven heating and higher energy bills. Before winter:
- Vacuum supply and return vents
- Remove any obstructions like furniture or rugs
- Consider scheduling duct cleaning if you notice dust buildup or inconsistent airflow
6. Inspect the Furnace Exhaust Flue
A blocked exhaust flue can create dangerous carbon monoxide buildup. Before turning your furnace on for the season:
- Check that the vent pipes are clear of debris, nests, or ice
- Make sure there are no cracks or rust that could leak fumes
- Install a carbon monoxide detector near your furnace and bedrooms for safety
7. Reverse Ceiling Fans
Did you know ceiling fans can help keep your home warmer in the winter? By reversing your fans to spin clockwise, you push warm air down from the ceiling, allowing your furnace to run more efficiently.
8. Stock Up on Furnace Filters & Emergency Supplies
Michigan winters can be unpredictable. Keep a supply of replacement filters on hand and consider stocking up on essentials in case of a furnace emergency:
- Portable space heaters
- Extra blankets
- Backup power supply (for severe storms)
9. Plan for Furnace Repairs in Advance
Even with the best preparation, HVAC systems can fail. Having a trusted heating repair company in Howell, MI on speed dial ensures you’re not scrambling when the furnace goes out in the middle of a snowstorm.
At Oak Grove Heating and Cooling, we provide 24/7 emergency heating repair services so you never have to go without heat.
10. Consider a Furnace Upgrade if Needed
If your furnace is 15–20 years old, inefficient, or requires frequent repairs, upgrading before winter may save you money in the long run. Modern furnaces are:
- More energy-efficient
- Quieter
- Equipped with smart technology
- Eligible for rebates and tax credits
Preparing Commercial HVAC Systems for Michigan Winters
