Winter Furnace Maintenance Tips for Georgia Homeowners

While Georgia winters may be milder than northern states, your furnace still works hard to keep your family comfortable during those chilly months. Proper winter furnace maintenance not only ensures reliable heating but also helps you save money on energy bills and prevents costly breakdowns.

At Duncan Heating and Air Services, we've been helping North Georgia families maintain their HVAC systems for years. Here are our top winter furnace maintenance tips to keep your system running smoothly throughout the season.

Essential Pre-Winter Furnace Checks

Replace Your Air Filter

Your furnace filter is the first line of defense against dust, debris, and allergens. A clogged filter forces your system to work harder, increasing energy costs and reducing efficiency.

• Check your filter monthly during heating season
• Replace standard 1-inch filters every 1-3 months
• Consider upgrading to higher-efficiency filters for better air quality
• Mark your calendar as a reminder

Inspect and Clean Vents and Registers

Blocked vents can create uneven heating and strain your furnace. Walk through your home and ensure all supply and return vents are clear.

• Remove furniture, rugs, or curtains blocking vents
• Vacuum dust and debris from vent covers
• Check that dampers are open in rooms you want heated
• Close vents in unused rooms to improve efficiency

Safety First: Carbon Monoxide Prevention

Test Your Carbon Monoxide Detectors

Carbon monoxide is a silent, deadly threat that can result from faulty furnace operation. This odorless gas can be lethal, making working detectors essential.

• Test detectors monthly and replace batteries twice yearly
• Install detectors on every level of your home
• Place units near sleeping areas for maximum protection
• Replace detectors every 5-7 years

Watch for Warning Signs

Be alert for these potential carbon monoxide indicators:

• Yellow or flickering furnace flames (should be blue)
• Soot buildup around the furnace
• Excessive moisture on windows
• Frequent headaches or flu-like symptoms

Energy Efficiency Tips for Georgia Winters

Optimize Your Thermostat Settings

Smart thermostat programming can significantly reduce your heating costs without sacrificing comfort.

• Set temperature to 68°F when home and awake
• Lower by 7-10 degrees when sleeping or away
• Use programmable or smart thermostats for automatic adjustments
• Avoid frequent temperature changes that waste energy

Improve Home Insulation

Even in Georgia's mild climate, proper insulation makes a difference in heating efficiency.

• Check attic insulation levels (should be 10-14 inches deep)
• Seal gaps around windows and doors with weatherstripping
• Use draft stoppers under doors
• Consider upgrading to energy-efficient windows

Monthly Maintenance Tasks

Check Your Furnace Area

Keep the area around your furnace clean and safe:

• Maintain 3 feet of clearance around the unit
• Remove stored items, especially flammables
• Ensure adequate ventilation
• Check for unusual noises, odors, or vibrations

Monitor System Performance

Stay alert to changes in your furnace's operation:

• Listen for unusual sounds like grinding, squealing, or banging
• Notice if some rooms aren't heating properly
• Watch for frequent cycling on and off
• Check that warm air is flowing from vents

When to Call a Professional

• No heat or insufficient heating

Preparing for Georgia's Unpredictable Weather

Georgia weather can be unpredictable, with sudden temperature drops catching homeowners off guard. Don't wait until the first cold snap to discover your furnace isn't working properly.
