As summer winds down in Northern Michigan, homeowners start thinking about cozy evenings, warm drinks, and the crisp fall air. But before you pull out your favorite sweater, it’s crucial to ensure your HVAC system is ready for the seasonal transition. Preparing your system now can prevent unexpected breakdowns, improve efficiency, and keep your home comfortable all season long.

At Mammoth Mechanical, we’ve helped Northern Michigan homeowners for over 20 years keep their heating and cooling systems running smoothly.

Here’s a practical guide to getting your HVAC system ready for the shift from cooling to heating mode.

1. Adjust Your Thermostat for Seasonal Comfort

Your thermostat is the heart of your home’s HVAC system. As temperatures drop, you’ll want to adjust your thermostat settings to maintain comfort while avoiding unnecessary energy costs.

Set a baseline temperature: Experts recommend keeping your home around 68°F during the day when you’re home, and lowering it slightly at night or when the house is empty.
Consider a programmable thermostat: These devices automatically adjust temperatures based on your schedule, keeping energy bills in check without sacrificing comfort.
Test your system: Before the cold hits, switch your thermostat to heating mode to ensure the system responds properly.

2. Perform End-of-Summer AC Maintenance

Even though you won’t be running your air conditioner as much, neglecting end-of-summer maintenance can lead to problems when the heat returns.

Clean or replace filters: Dirty filters reduce airflow and make your AC work harder, even when stored for the season.
Inspect outdoor units: Remove debris, leaves, and dirt around your condenser unit to prevent damage and improve efficiency.
Check for leaks or wear: Look for signs of refrigerant leaks, worn belts, or unusual noises. Addressing these issues now can prevent costly repairs later.

Performing these steps ensures your AC remains in good shape and is ready for next year.

3. Schedule a Pre-Heating Season Tune-Up

Northern Michigan winters can be harsh, and an unexpected furnace breakdown in January is the last thing you want. A professional HVAC tune-up ensures your heating system is safe, efficient, and reliable.

Inspection and cleaning: A licensed technician from Mammoth Mechanical will inspect key components, clean the system, and make minor adjustments to optimize performance.
Safety checks: We’ll examine your furnace for carbon monoxide leaks, proper venting, and electrical safety.
Efficiency optimization: Regular maintenance improves energy efficiency, potentially lowering your heating bills and extending your system’s lifespan.

4. Seal and Insulate Your Home

Even the best HVAC system can struggle if your home isn’t properly sealed for the season.

Check for drafts: Inspect doors, windows, and vents for air leaks.
Seal gaps: Use weatherstripping or caulk to close openings and reduce heat loss.
Insulate ducts and pipes: Proper insulation prevents heat loss, ensuring warm air reaches every room efficiently.

These small steps can make a noticeable difference in your comfort and energy costs.

5. Monitor Humidity Levels

Heating your home can dry out the air, causing discomfort and potential damage to wood floors and furniture.

Use a humidifier: Maintaining indoor humidity between 30–50% improves comfort and protects your home.
Ventilation check: Make sure exhaust fans and vents are working correctly to prevent excess moisture buildup in certain areas, like bathrooms and kitchens.
