How to Transition Your HVAC System from Cooling Your Home to Heating

As crisp Kansas mornings arrive, it’s time to transition your HVAC system from AC to heat. At Comfort Systems in Wichita, we help you make the switch right—boosting comfort, efficiency, and safety for the new season.
HVAC Seasonal Changeover: The Step-by-Step Wichita Checklist
- Finish cooling season
- Prep the furnace
- Change thermostat mode
- Book professional tune-up
Step 1: Wrap Up the Cooling Season
- Replace/clean air filters: A clean filter is essential for both AC and heat performance.
- Inspect outdoor unit: Remove leaves and debris for smooth running and easier winterization.
- Check for odd smells/sounds: Fix minor issues before the switch to heat.
Step 2: Give Your Furnace a Once-Over
- Test the furnace early: Don’t wait for the first cold snap—check for start-up or noise issues now.
- Listen & sniff: A mild burning smell is normal (dust); gas or strong odors are a red flag—call for service.
- Check vents & ducts: Ensure nothing is blocking airflow for even comfort.
Step 3: Thermostat & System Mode Change
- Set to “heat” mode: Simple but crucial—be sure your thermostat is set for heating!
- Increase temps gradually: Avoid jumping the setting up by 10° at once; ease into fall for savings and system health.
- Check/adjust programmable schedule: Update for chilly nights and busy mornings.
Step 4: Consider Professional Maintenance
Signs You Need Attention During Changeover
- Uneven heat/cold rooms: Check vents and blower; could be duct issues.
- Unusual noises: Rattles, squeals, or bangs need attention.
- Energy bill spike: Sudden jump usually means a system working too hard.
- Constant cycling: Frequent on/off often signals the need for a quick adjustment or repair.
