Winter 2026–27: where heating, plumbing and water damage demand will land

The winter setup has flipped from last year. NOAA's Climate Prediction Center expects a strong to very strong El Niño through January–March 2027, which usually means a milder North and a wetter South.

What the forecasts say

• El Niño is in charge. On October 8, CPC put the chance of a historically strong event at 83% for October–December. NOAA CPC
• Heating demand shifts west. EIA's Winter Fuels Outlook (Oct 6) has heating degree days down 12% in the Northeast and 2% in the Midwest, up 1% in the South and up 25% in the West versus last winter. EIA
• Search still peaks in January. Monthly searches for "furnace repair" climb from about 34,000 in September to about 62,000 in January, then fall back in February. WebFX / Ahrefs

Cold snaps decide the season

Averages hide the money. During a January 2024 Arctic snap, one North Dakota HVAC owner saw service calls roughly triple (KFYR). After the late-January 2026 storm, a Jacksonville company logged more than 200 heating calls in a weekend (Action News Jax). Southern markets get short, sharp spikes; northern markets carry steady volume.

What to do with it

• HVAC: plan crews and budgets around cold-snap forecasts, not the calendar. Expect the West to be busier than last year.
• Plumbing and water damage: frozen-pipe calls follow the same cold snaps, and El Niño's wetter South brings more flood and roof-leak water damage.
• Media buyers: raise caps and bids by state when freeze and winter-storm alerts go up. The Demand Index tracks those alerts live.
