There are several different symptoms that can indicate that your furnace is leaking gas. One of the most noticeable signs of a furnace leak is when you feel it coming out of your vents or registers when you open them. This may come as a surprise to you as you normally do not use these vents often. You will probably notice that the gas leak comes out through the registers when you shut them off, but you should also be able to feel it on the side of your throat and in your nostrils. In some cases, if your furnace does not run properly, you may find that you can feel the leak. If you find that you are having this problem, you should call your furnace service company right away.
One of the other common signs of your furnace leaking gas is when you detect the smell coming from the vents. When you are doing something that might cause the gas to escape, it is important that you keep an eye on what you are doing while you are shutting off your furnace. If you find that your furnace is acting up and making strange noises that you do not normally feel, then you should take it in for service right away. Your furnace may have a broken thermostat, which means that the temperature will not return to normal once the thermostat is turned off. You should always check your furnace when it is hot. If you do not feel any leaking gas, then it is time to call your furnace service company.
If your furnace seems to be leaking more often than usual, it may be time to have your furnace cleaned by a professional. He will be able to determine what the cause of the problem is and how you can fix it. Having your furnace cleaned at least once a year will prevent it from costing you more money in repairs down the road. Also, having your furnace serviced once a year will keep you from suffering unnecessary energy costs as well as help you keep your home comfortable and warm.
