What Is a Dual Fuel HVAC System?
San Francisco winters are milder than cities in Northern states, which is why San Franciscans have little use for high-capacity heating and air conditioning systems. Instead, most opt to use heat pumps, which offer better energy efficiency for homes in milder climates. Heat pumps don’t consume as much energy or fuel as, say, a furnace. This means they also don’t produce the same amount of heat, making them perfect for a San Franciscan winter.
