Heat Pump, HVAC & Water Heater Services in Sebastopol, CA
Heat pumps, water heaters, AC, furnaces, and mini splits for Sebastopol homes. Same-day water heater replacement when our schedule allows.
Green Core Heating & Air installs and services heat pumps, water heaters, air conditioning, furnaces, and ductless mini splits for homes in Sebastopol, CA, from older farmhouses and cottages to modern, eco-conscious builds. The climate here is shaped by coastal influence, morning fog, and warm afternoons, which creates a unique balance of temperature and moisture. That means your HVAC system needs to do more than just heat and cool — it needs to manage airflow, humidity, and efficiency all at once.
Whether you're spending the day at the Sebastopol Farmers Market, exploring The Barlow, or enjoying the surrounding orchards and open space, you want to come home to a space that feels comfortable and balanced. If your home feels damp in the mornings, uneven throughout the day, or struggles to maintain temperature, it's often a sign the system wasn't designed for Sebastopol's conditions.

Designed for Sebastopol Homes
Sebastopol homes vary widely — from older farmhouses and cottages to custom-built properties and modern eco-conscious homes. Many properties sit on larger lots or have unique layouts, which can create airflow challenges and inconsistent temperatures if the system isn't properly designed.
At Green Core Heating & Air, we provide heat pump installation, air conditioning services, furnace repair, mini split systems, and ductwork upgrades tailored to these homes. We often help homeowners transition to more efficient, all-electric systems like heat pumps, which work especially well in Sebastopol's moderate climate.
Instead of simply replacing equipment, we take a whole-home approach — evaluating how your home performs so we can recommend solutions that improve comfort, efficiency, and reliability.

Built for Comfort, Efficiency, and Air Quality
In Sebastopol, comfort isn't just about temperature — it's about how the home feels throughout the day. Coastal air, agricultural surroundings, and seasonal changes can all impact indoor air quality and humidity levels.
After a day spent outdoors or at local spots like Ragle Ranch Regional Park, you should be able to come home to clean, comfortable air. Whether you need heat pump installation, AC repair, furnace service, or airflow improvements, we design systems that improve both comfort and indoor air quality — without overcomplicating things.
