What 25° Nights Mean for Your Heating System and Energy Bill

Sponsored by SA Sloop Heating & Air Conditioning

After a weekend of snow showers in the mountains and sub-freezing lows across Rowan County, many furnaces and heat pumps got their first true workout of the season. As temperatures dipped into the mid-20s Monday morning, homeowners may have noticed longer heating cycles, higher thermostat readings, and that first real jump in energy use since spring.

Cold Nights Test Your System

When outside air falls below 30°, your heating system works harder to maintain a comfortable indoor temperature. Heat pumps in particular become less efficient as they extract warmth from the cold air, causing auxiliary or “emergency” heat to engage more frequently. This leads to temporary spikes in power consumption — especially overnight when temperatures bottom out.

If your system ran longer than usual this week, that’s normal. But it’s also a reminder that late fall is the ideal time for a quick inspection or tune-up. Ensuring filters are clean, vents are clear, and thermostats are calibrated correctly helps prevent overworking your unit during these early-season cold snaps.

Efficiency Improves Later This Week

The good news: a strong warming trend arrives mid-week. Highs will climb into the 60s by Wednesday and Thursday, and near 70° by Saturday. With daytime sunshine and calmer winds, heating systems will cycle far less often — giving both your equipment and your wallet a short break before winter sets in.

Energy-Saving Tip

If you’re adjusting your thermostat manually, try keeping it just one or two degrees lower overnight and using a heavier blanket or comforter. Every degree makes a difference — and with nights still dipping into the 30s through mid-week, those small changes add up on the monthly bill.
