Fall HVAC Transition: Switching from Cooling to Heating in East Texas

Why now?

East Texas gets 20–40 heating days per year, but they arrive unpredictably — sometimes as a hard freeze with little warning. Discovering your furnace doesn't work at 11pm in late November is avoidable.

Your Checklist

• ✓Test your heating system on a mild day before you actually need it — run it for 30 minutes
• ✓Replace air filter before switching to heating mode
• ✓Check gas connections and smell for any gas odors (call gas company immediately if detected)
• ✓Inspect heat pump reversing valve operation — should switch from cooling to heating mode smoothly
• ✓Schedule a furnace or heat pump service if not done in the past 12 months
• ✓Test carbon monoxide detectors and smoke alarms — replace batteries if needed
• ✓Check your attic for animal nesting activity that could block vents (fall is prime season)
• ✓Seal any air leaks found around window frames and door thresholds before heating season
