Why Your Furnace Might Struggle During Extreme Cold — And What to Do

When it’s -10°F outside, even a good furnace can struggle. But what’s normal... and what’s a sign of trouble?

Signs your furnace is overwhelmed:

• It runs constantly and never reaches the set temp
• Some rooms stay cold while others overheat
• Your energy bill spikes unexpectedly

What to do:

• Seal up drafts around doors and windows
• Add insulation in attics and crawlspaces
• Ask about dual-fuel or high-efficiency upgrades

Stay ahead of winter’s worst — and don’t wait until your system fails.
