Dual Fuel Systems

Dual Fuel Systems: Precision Temperature Control for Every Season 

Looking for a smarter, more efficient way to heat and cool your home? Choosing a dual fuel system is the ultimate upgrade—combining the power of an electric heat pump with the reliability of your existing gas furnace. This dual-fuel system automatically chooses the most cost-effective and energy-efficient heating method based on the weather and your home’s needs with up to a $2,000 Federal Tax Credit (learn more here), National Grid rebates up to $600 (learn more here), and a 21 Seer (Seasonal Energy Efficiency Ratio) rating.

Welcome to Hybrid HVAC

Eco-efficient Comfort

Mitsubishi Electric’s intelli-HEAT™ Dual Fuel System consists of 2 units: an exterior heat pump, which replaces your existing air conditioning condenser, and an interior unit that is installed on your existing furnace*. This smart system not only improves air conditioning efficiency on hot days, but also determines the best source of heat (gas or electricity) on cold days, so your HVAC system is always running at peak efficiency and comfort.

*Mitsubishi Electric air conditioner and heat pump systems should only be connected with ANSI-Z21.47/CSA2.3 certified furnaces.
