Heat Pump, HVAC & Water Heater Services in Santa Rosa, CA
Heat pumps, water heaters, AC, furnaces, and mini splits for Santa Rosa 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 Santa Rosa, CA, from historic homes near downtown to hillside builds in Fountaingrove and Bennett Valley. As Sonoma County's largest city, Santa Rosa has a wide mix of neighborhoods, climates, and home styles — and your HVAC system needs to be designed around your specific home, not a generic template.
Whether you're spending the day in Railroad Square, hiking Annadel State Park, or enjoying time around Howarth Park, you should be able to come home to a space that feels balanced and comfortable. If your system runs constantly, leaves rooms uneven, or drives up your energy bills, it's usually a sign the system wasn't designed for your home's real conditions.

Designed for Santa Rosa Homes
Santa Rosa neighborhoods range from historic homes near downtown to newer builds in Fountaingrove, Bennett Valley, and the west side. Each comes with its own challenges — older homes may have outdated ductwork or airflow limitations, while newer hillside properties deal with sun exposure and temperature variation.
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. We take a design-first approach — evaluating how your home performs so we can recommend solutions that actually fix the problem, not just swap equipment.
