One thing you can be sure of is this: replacing an old furnace is definitely worthwhile. Modern furnaces are able to burn gas much more efficiently than older models, which means you will use less gas. In this way, you can save on your regular heating costs. We estimate that homeowners can save as much as 30%.

Is gas furnace replacement always necessary? No! In some cases, the furnace can be repaired. The best way to ensure that your furnace is suitable for repair is to act quickly, as soon as you notice a problem. For example, it’s easy to ignore a furnace that is making strange noises or producing a lot of soot, but you really shouldn’t. The sooner you get these issued looked at by a professional, the lower the chance of irreversible damage occurring.

Some of the other signs of your furnace starting to struggle include a pilot light that will not stay lit, or a furnace that’s difficult to start. You might also notice a decline in indoor air quality.
