Heating in Florida. There is aways that two weeks out of the year we need our air system to heat our homes. Florida is about choices and here we have 3 different options: First we have the Electric supplimental heat installed in an air handler. These are the cheapest to buy and most expensive to run. Second we have Gas Furnaces. These are the most expensive option, but they make the most heat the fastest. Third we have heat pumps. These make great heat, but can struggle when the outdoor temperature drops below 40 degrees. Call us to help you decide on what would be your best fit.
