Happy New Year! 🎉 As the holiday decorations have come down and routines settle back in, winter is still very much here and your HVAC system is likely getting a well-earned workout. No service pro required, yet.

So starting the year with the right HVAC settings can help you stay comfortable, keep energy bills under control, and reduce the chance of unexpected breakdowns…something every homeowner can appreciate.

Here’s how to keep your home warm, efficient, and protected all winter long.

The Ideal Winter Thermostat Settings 🏠 When You’re Home

Set your thermostat to 68°F–70°F

This range balances comfort with energy efficiency

Each degree above 70°F can increase heating costs by up to 3%

*Pro tip: Cozy sweaters and blankets go a long way toward comfort—without overworking your system.

At Night or When You’re Away 🌙

Lower your thermostat to 60°F–65°F

Cooler nighttime temperatures reduce energy use and are often more comfortable for sleeping

For extended time away, lowering the heat helps save money without risking frozen pipes

Programmable or smart thermostats make these adjustments automatic—and stress-free.

Use “AUTO,” Not “ON,” for the Fan

During winter, your fan setting matters more than many homeowners realize.

Set your fan to AUTO

This allows the blower to run only when the system is actively heating

Why it matters:

Reduces energy consumption

Limits wear and tear on the blower motor

Prevents unnecessary circulation of dry winter air

Manage Indoor Humidity for Comfort & Efficiency

Cold winter air is naturally dry—and dry air can make your home feel colder than it actually is.

Ideal winter humidity:

30–40%

Proper humidity helps:

Make lower temperatures feel warmer

Reduce static electricity

Improve overall comfort without increasing heat output

Options to consider:

Whole-home humidifiers

Portable humidifiers in frequently used rooms

Avoid Common Winter HVAC Mistakes

To keep your system running efficiently, avoid:

Turning the heat way up to “warm the house faster” (it won’t)

Shutting the system off entirely for long periods

Blocking vents with furniture, curtains, or rugs

Consistent, moderate settings are easier on your system—and your energy bill.

Winter HVAC Reminders Every Homeowner Should Know

Change Your Air Filter

• Replace filters every 1–3 months
• Dirty filters restrict airflow and can lead to system strain or breakdowns

Check Outdoor Units

• Keep heat pumps and outdoor units clear of snow, ice, and debris
• Maintain at least 2 feet of clearance around the unit

Watch for Warning Signs Contact a professional if you notice:

• Uneven heating
• Unusual noises or burning smells
• Short cycling (frequent on/off cycles)
• A sudden spike in energy bills

Schedule Preventive Maintenance Annual winter maintenance can:

• Improve system efficiency
• Catch small issues before they become major repairs
• Extend the life of your HVAC system
