Nobody wants to risk the lives of their loved ones and neither would you. It is, therefore, important that you make sure none of the home comfort heating and cooling appliances at your home is a potential threat to your life and the life of your loved ones. Many appliances use natural gas to work. While this gas helps them work, it should also be noted that natural gas is highly combustible. It burns and can put everything on fire with a slight flame. The problem begins when gas from heating and cooling appliances begin to leak. This problem could occur with any home comfort devices but mainly with the furnaces and the water heaters.
