Carrier 38MURAQ dual fuel system installation in Foster City, CA

We installed a Carrier 38MURAQ dual fuel system, pairing a high-efficiency heat pump with a gas furnace so the home stays comfortable in any weather. This hybrid setup gives you the best of both worlds: electric heating and cooling for most of the year, with gas heat ready to take over when temperatures drop.

By automatically choosing the most efficient heat source for current conditions, a dual fuel system smooths out temperature swings and helps keep energy bills predictable instead of letting one fuel do all the work. In milder weather the heat pump handles heating and cooling on its own; when it gets colder and a heat pump becomes less efficient, the gas furnace steps in to deliver fast, powerful heat.

Why a dual fuel system works so well

• Energy efficiency: smart controls switch between electric and gas heating to optimize performance and running costs.
• Year-round comfort: the system holds consistent temperatures, even in more extreme conditions.
• Eco-friendly operation: leaning on the heat pump for everyday heating and cooling reduces overall energy use.
• Quiet performance: advanced sound-reducing features keep the equipment unobtrusive indoors and out.

This Carrier 38MURAQ is a strong fit for homeowners who want efficient cooling, reliable heating, and lower long-term operating costs from a single integrated system. As with every Nur HVAC project, the unit was set with clean line sets and fully tested and commissioned before we left, so it performs the way it should from day one.
