If you need furnace repair or furnace replacement best thing you can do is to call a company who specializes in these type of services. Problems tend to appear especially when you have a gas furnace. Even though gas furnaces and heaters have control shutoffs to prevent gas leaks, they are not fail-safe and in the event you smell gas in your home you should first think about your family's safety and immediately get out of the house, leave the door open and call the gas company or the fire department.

One of the things you can do is to make sure the air filter is cleaned or changed on a regular basis, after all, they heat air, which is then moved through the house using a blower motor. If you decide you don't want to run the risk of calling the fire department you can always go for an oil furnace instead of a gas one.
