Quail Creek homes run on propane gas. Your tank is either above ground adjacent to your home or buried underground behind your home. Many homes lease their tanks from one of the service providers listed below so you can expect to receive an annual bill for this lease on top of what you pay for gas. Be aware that of all your utilities, gas will be the most expensive because propane is a gas by-product where the price rises and falls with the market. Your service provider should be able to tell you how large your tank is, normally 250 to 500 gallons.
