GUIDE: Seasonal HVAC Maintenance Tips for California Homeowners
Key Takeaways
- Seasonal HVAC maintenance is the key to comfort, efficiency, and lower energy bills all year long.
- Each season in California demands a different focus: cooling in summer, heating in winter, and tune-ups in between.
- Proactive care for systems like heat pumps, mini-splits, smart thermostats, and ductwork can prevent costly repairs and extend equipment life.
At Elevated Comfort, we’ve helped thousands of California homeowners keep their HVAC systems running smoothly, no matter the season. Our unique climate in Northern California means your heating and cooling needs shift throughout the year, and your HVAC maintenance routine should shift with them.
This guide offers a complete, season-by-season breakdown of how to care for your system, avoid emergencies, and stay comfortable 365 days a year. Whether you use a heat pump, ductless mini-split, or traditional furnace and AC system, this guide will help you stay ahead of the curve.
Winter HVAC Maintenance in California
Even though Northern California winters are mild compared to the East Coast, your heating system still works overtime during the colder months. A well-maintained system ensures you stay warm and energy-efficient.
Key Winter Maintenance Tasks:
- Replace filters monthly if you’re running your system frequently.
- Inspect and clean furnace burners, pilot light, and heat exchanger.
- Test your thermostat to ensure accurate temperature control.
- Clear debris from outdoor heat pump or mini-split components.
- Check for signs of carbon monoxide leaks in older heating systems.

Tip from the Field:
Many no-heat calls we get in January could have been avoided with a quick pre-season tune-up in November. Don’t wait until you’re cold.
Spring HVAC Maintenance in California
Spring is a great time to clean, reset, and prepare your HVAC system for the hotter months ahead. Pollen, dust, and fluctuating weather can strain your equipment, especially if it’s been dormant.
Key Spring Maintenance Tasks:
- Clean around outdoor AC or heat pump units, removing leaves and debris.
- Inspect ductwork for leaks, mold, or disconnected joints.
- Change air filters and clean vents to improve air quality and airflow.
- Test your cooling system early, before the first 90°F day arrives.
- Clean or upgrade your smart thermostat settings for seasonal shifts.
If your ducts are leaking or full of debris, it might be time to consider Duct Replacement.
Summer HVAC Maintenance in California
When temperatures climb past 90°F in Santa Rosa, Healdsburg, or Marin, your AC system becomes the most important appliance in your home. Summer maintenance isn’t optional, it’s essential for cooling efficiency and energy savings.
Key Summer Maintenance Tasks:
- Schedule a professional AC tune-up before the first heat wave.
- Clean condenser coils and check refrigerant levels.
- Clear obstructions around the outdoor unit (fencing, plants, debris).
- Inspect the blower motor and fan belt for wear.
- Ensure proper thermostat calibration for better zone control.

Bonus Tip:
Summer is also the perfect time to replace older systems with energy-efficient options. Ask us about ductless mini-splits for room-by-room cooling and long-term savings.
Fall HVAC Maintenance in California
Autumn is the ideal time to shift your HVAC system from cooling mode to heating readiness. It’s also when wildfires, falling leaves, and smoke can clog filters and ducts, affecting your indoor air quality and equipment performance.
Key Fall Maintenance Tasks:
- Check and replace air filters, especially after wildfire season.
- Inspect water heaters for leaks and sediment build-up.
- Schedule a pre-winter furnace or heat pump tune-up.
- Reprogram your smart thermostat for fall-to-winter temperature shifts.
- Test CO and smoke detectors, especially if you use gas heating.

Year-Round Maintenance Tips from Elevated Comfort
In addition to seasonal tasks, here are smart habits to keep your system running smoothly:
- Keep at least 2 feet of clearance around all HVAC units.
- Use ceiling fans to reduce load on AC or heating systems.
- Join a preventative maintenance program to stay on schedule.
- Track your energy usage. Sudden spikes often signal HVAC issues.
- Know your equipment’s age. Most systems last 10–15 years with care.
