Heat Pump, HVAC & Water Heater Services in Novato, CA
Heat pumps, water heaters, AC, furnaces, and mini splits for Novato 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 Novato, CA, from hillside homes that bake in the afternoon sun to established neighborhoods with older systems. Novato offers a unique blend of suburban comfort and open space, but that also means homes here experience a wide range of conditions — from warm afternoons to cool evenings. Your HVAC system needs to keep up with those shifts without overworking or driving up energy costs.
Whether you're spending the day hiking around Stafford Lake Park, exploring Indian Valley Preserve, or enjoying time near Downtown Novato, you should be able to come home to a space that feels consistently comfortable. If your system struggles with hot and cold spots or never quite feels right, it's often a design issue — not just the equipment. That's where we focus our work.

Designed for Novato Homes
We provide heat pump installation, air conditioning repair, furnace services, mini split systems, and ductwork upgrades tailored specifically to Novato homes. Many properties here — especially hillside homes or those with more sun exposure — experience uneven temperatures throughout the day. Others have older systems that were never properly sized or balanced.
Our approach is different. Instead of simply replacing equipment, we evaluate how your home actually performs. We look at airflow, layout, insulation, and usage patterns to design a system that works as a whole. Whether it's upgrading to a high-efficiency heat pump, improving ductwork, or installing a ductless mini split for targeted comfort, we focus on creating solutions that deliver real results.

Built for Comfort, Efficiency, and Long-Term Performance
Novato's climate may seem mild, but the variation between neighborhoods and home styles makes system performance especially important. After a day outdoors at places like Olompali State Historic Park or enjoying local community spaces, your home should feel like a consistent, comfortable environment — without constantly adjusting the thermostat.
We design systems that operate efficiently, quietly, and reliably over time. Whether you need AC repair, furnace replacement, heat pump installation, or ductwork improvements, our goal is to create a system that performs the way it should — day in and day out.

Why We Love Novato
Novato has a pace that's hard to beat — it's connected to the rest of Marin County, but still feels relaxed and grounded. With access to open space, historic sites, and a strong sense of community, it's a place where people truly enjoy being home.
We especially appreciate the variety of homes here, from established neighborhoods to hillside properties with incredible views. That variety means every project is different, and we take pride in designing systems that match each home's specific needs. Helping homeowners solve comfort issues and improve efficiency in a place like Novato makes the work meaningful.
