If you’re leaving White Bear Lake for a vacation — whether it’s a winter escape or a summer lake trip — you may be wondering:
What should I do with my thermostat?
Should I turn my system off?
How do I protect my home while I’m gone?
Your HVAC system plays an important role in protecting your home while you’re away — especially in Minnesota’s extreme seasons.
Here’s how to prepare properly.
Should I turn my HVAC system off when I leave?
Short Answer:
No. In Minnesota, you should never fully shut off your HVAC system during winter — and rarely in summer.
Expanded Explanation:
In winter, turning your furnace off can lead to:
- Frozen pipes
- Interior damage
- Ice buildup
In summer, shutting off AC completely may:
- Increase humidity
- Encourage mold growth
- Cause indoor air stagnation
Instead of turning it off, adjust the temperature strategically.
What temperature should I set my thermostat in winter while away?
Short Answer:
Set your thermostat between 55–60°F during winter vacations.
Expanded Explanation:
Keeping the temperature above 55°F helps:
- Prevent frozen pipes
- Protect drywall and flooring
- Maintain minimal system operation
Even if you’re gone for a week or two, maintaining baseline heat protects your home.
What temperature should I set it in summer?
Short Answer:
Set your thermostat between 78–85°F during summer trips.
Expanded Explanation:
This reduces energy use while:
- Controlling humidity
- Preventing extreme indoor heat buildup
- Protecting electronics and furnishings
In humid Minnesota summers, maintaining airflow prevents moisture problems.
Should I change my air filter before leaving?
Short Answer:
Yes, especially if it’s close to replacement time.
Expanded Explanation:
A clean filter ensures:
- Proper airflow
- Reduced system strain
- Efficient operation while unattended
You don’t want a clogged filter restricting airflow while you’re away.
Is humidity control important while on vacation?
Short Answer:
Yes. High humidity can cause mold, odors, and material damage.
Expanded Explanation:
White Bear Lake summers can be humid — especially near the lake.
Maintaining moderate cooling helps:
- Control moisture
- Prevent musty smells
- Protect hardwood floors
Humidity matters just as much as temperature.
Should I close vents or doors before leaving?
Short Answer:
No. Keep vents open to maintain balanced airflow.
Expanded Explanation:
Closing vents can:
- Increase duct pressure
- Reduce system efficiency
- Cause uneven airflow
Leave interior doors slightly open to allow circulation.
What if I’ll be gone for a month or longer?
Short Answer:
Consider scheduling a system check before extended travel.
Expanded Explanation:
For long trips:
- Have your furnace or AC inspected
- Replace filters
- Ensure thermostat programming works correctly
- Confirm outdoor unit is clear
Proactive checks reduce risk while your home is unoccupied.
Should I use a smart thermostat?
Short Answer:
Yes. Smart thermostats allow remote monitoring and adjustment.
Expanded Explanation:
With a smart thermostat, you can:
- Adjust temperature remotely
- Monitor indoor conditions
- Detect unusual changes
If temperatures drop unexpectedly in winter, remote alerts can prevent damage.
What about outdoor HVAC units?
Short Answer:
Inspect and clear debris before leaving.
Expanded Explanation:
Before vacation:
- Remove leaves or snow buildup
- Ensure proper clearance
- Check for visible damage
Outdoor airflow is essential for proper system operation.
