San Rafael Heating & Air Conditioning Services
Trusted HVAC experts in San Rafael, CA.
At Green Core Heating & Air, we provide dependable heating and cooling services designed for homes throughout San Rafael. The climate here sits right in between coastal and inland conditions, which means your HVAC system needs to handle both cooler marine air and warmer inland temperatures — often in the same day. Getting that balance right is what makes the difference between a system that works and one that actually feels comfortable.
Whether you're spending the afternoon exploring China Camp State Park, walking through Downtown San Rafael, or enjoying the local shops and restaurants, coming home should feel consistent and comfortable. If your system struggles with uneven temperatures, hot upstairs rooms, or constant cycling, it's usually not just the equipment — it's how the system was designed.

Designed for San Rafael Homes
San Rafael has a wide mix of home styles — from older homes near downtown to hillside properties and newer builds spread throughout the area. Each one comes with its own HVAC challenges. Hillside homes often deal with sun exposure and temperature variation, while older homes may have outdated ductwork or airflow limitations.
At Green Core Heating & Air, we provide heat pump installation, air conditioning services, furnace repair, mini split systems, and ductwork upgrades tailored to these conditions. Instead of simply replacing your system, we evaluate how your home actually performs — looking at airflow, layout, and insulation — to design a solution that works as a whole.
Whether it's upgrading to a high-efficiency heat pump, improving airflow with ductwork modifications, or installing a mini split for targeted comfort, we focus on solutions that fix the problem at the source.

Built for Comfort, Efficiency, and Consistency
San Rafael's mix of coastal influence and inland warmth makes consistency one of the biggest challenges for homeowners. After a day out enjoying the trails at China Camp or spending time downtown, you want to walk into a home that feels balanced — not one room warm and another cool.
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 keeps your home comfortable without constant adjustment or high energy costs.
