Leaky ducts can cause your electric bill to increase. When your cooling and heating duct system has leaks or holes in it, air is allowed to escape into the attic, which ends up wasting energy and costing you money. In fact, 50 percent of all homes have leaky ducts.
FPL representatives can visit your home and test your duct system. If repairs are needed, you might be entitled to an FPL rebate.
