Heating your home with a heat pump from Oxygen Air is the cheapest form of heating and cooling your home. From just 60 cents for every 8 hours of use* there is no better way than heating or cooling your home. And on cooling your heat pump / air conditioner will dehumidify as well. Not all heat pumps are equal. You will find that Fujitsu has some of the highest energy ratings and this is why we recommend Fujitsu heat pumps for most residential and commercial applications. This, coupled with a 6 year residential & commercial warranty on your Fujitsu heat pump, means your heat pump purchase is a safe one!
