Steps for a Successful HVAC Seasonal Shift from Warm to Cold

As temperatures drop in Chico and across Northern California, your HVAC system must transition smoothly from cooling to heating mode. A well-planned seasonal shift keeps your home comfortable and energy bills low. Follow these key steps to prepare your HVAC system for fall and winter.

1. Replace or Clean Air Filters

Before the first cold snap, check and replace your HVAC filters. Dirty filters restrict airflow, reduce efficiency, and force your system to work harder. Bob’s Air Repair recommends checking filters monthly and replacing them at least every 90 days.

2. Inspect and Clean Vents and Ductwork

Dust, pollen, and summer debris can accumulate in vents and ducts, lowering air quality and heating efficiency. A professional duct inspection and cleaning helps prevent clogs and improves airflow throughout your home.

3. Test Your Thermostat

Switch your thermostat from cooling to heating mode and set the desired temperature. Ensure it responds correctly and maintains steady heat. If you have a programmable or smart thermostat, review your schedule and adjust settings for energy savings during cooler months.

4. Schedule a Professional System Checkup

A seasonal tune-up is essential. Our licensed technicians inspect burners, heat exchangers, and electrical connections, lubricate moving parts, and check for carbon monoxide leaks—ensuring your furnace is safe and ready.

5. Check and Seal Drafts

Examine windows, doors, and duct joints for leaks. Sealing gaps with weatherstripping or caulk prevents warm air from escaping and reduces heating costs.

6. Clear the Outdoor Unit

Remove leaves, sticks, and debris from around your heat pump or outdoor unit. A clear area allows proper airflow and protects the system from damage during winter storms.
