How Do I Switch from AC to Heat Safely in Fall?
Understanding the Seasonal HVAC Transition
As fall arrives, homeowners often ask when and how to switch from air conditioning (AC) to heating. Making the transition safely ensures home comfort, preserves HVAC efficiency, and prevents unnecessary strain on your system.
At CJ's Heating & Cooling, we help clients in the Poconos and surrounding areas prepare their HVAC systems for seasonal changes, ensuring smooth transitions and energy-efficient operation.
Signs It’s Time to Switch
Outdoor Temperature Trends
A consistent drop in daytime highs below 65°F (18°C) and chilly nights signals the need to switch to heating.
AC Inefficiency
If your air conditioner struggles to maintain comfortable indoor temperatures or cycles excessively, it’s time to turn on the furnace or heat pump. Continuing to use AC in cooler weather can increase energy costs and wear out your system.
Indoor Comfort Indicators
- Persistent chills or cold spots in your home
- Difficulty maintaining even temperatures
- Increased use of supplemental heating
Steps to Safely Switch from AC to Heat
1. Turn Off the Air Conditioner
Before activating the heating system, turn off your AC to prevent system conflicts and reduce energy waste.
2. Inspect Your Heating System
- Furnace or heat pump inspection: Check for leaks, worn parts, or unusual noises
- Filter replacement: Ensure clean HVAC filters for improved airflow and air quality
- Thermostat check: Program for gradual temperature increases to avoid overloading the system
3. Check Ductwork and Vents
Ensure that vents are unobstructed and ductwork is sealed to maximize heat efficiency and prevent energy loss.
4. Perform a Test Run
Run your heating system briefly to confirm proper operation. Listen for unusual noises, check airflow, and verify that the thermostat maintains consistent temperatures.
Benefits of a Safe HVAC Transition
- Energy efficiency: Proper seasonal switching reduces energy consumption and lowers bills
- Comfort: Ensures consistent indoor temperatures without cold drafts
- System longevity: Reduces strain on both heating and cooling equipment
- Indoor air quality: Clean filters and properly functioning systems maintain healthy air
Tips for Ongoing Fall HVAC Maintenance
- Schedule seasonal inspections with professional HVAC technicians
- Keep thermostat settings consistent to avoid sudden spikes in usage
- Clear space around outdoor units to prevent debris or leaf buildup
- Monitor system performance to address minor issues before they become costly
These simple measures complement a safe transition from AC to heat while preserving efficiency and system health.
