When it comes to heating and cooling your home, why not have the best of both worlds? A high efficiency dual-fuel heat pump uses electricity to heat and cool the home and switches to gas heat backup when the temperature takes a dip during the cold, winter months. Not only can a dual-fuel system save you an average of 30-50% in energy costs it often pays for itself over time.

How? Heat Pump systems can heat a home for less money than gas heating because typically 85% of the heating needs come from first stage heating. Dual fuel systems have first stage heat pump heating systems with second stage gas heating – which replace traditional heat strips. This can be package or split system with propane or natural gas.

New system installations may now qualify for up to a $1000 rebate through Berkeley Electric Cooperative’s Dual Fuel program when switching from gas to dual fuel. Members can also qualify for up to $2,000 in federal tax credits as well.

A $500 rebate is available to members switching from a heat pump to a dual fuel system. Both rebates are limited to one per home.

So why not earn up to $3,000 in savings toward making your home more comfortable and energy efficient?
