This is Comfort Bear, here to tell you more about furnaces. Lucky for me I don’t really need a furnace. To be honest, I’m already looking forward to the feeling of cool air from an AC unit blowing through my fur…
Sorry, spaced out there for a second. As I was saying: furnaces. Gas furnaces are incredible devices, and they’re crazy popular across the whole nation. Even so, you want to make sure it runs safely all year long. Gas appliances are safe when installed by a pro, but even then, they can fall into disrepair and invite some trouble.
Here are some of the common safety issues you can look out for with your own furnace:
Heat Exchanger Cracks
As your furnace begins to age, you should keep an eye on the heat exchanger. This is the component that’s responsible for heating the air. It constantly expands and contracts during operation, and over time, that can lead to cracks and deterioration. If you notice cracks in your heat exchanger, stop running it and immediately call for furnace repairs in Independence, MO, as it can cause a carbon monoxide leak or other serious problems.
Cracks or corrosion in the flue pipe are equally as dangerous as a cracked heat exchanger. The flue pipe’s purpose is to vent out carbon monoxide and exhaust from the furnace. If the flue is cracked or corroded, those poisonous gasses can flow into your home!
Also, before you fire up the furnace for the first time every season, make sure to have the flue checked for obstructions. It’s not uncommon for birds to build their nests inside the flue. That can restrict airflow and lead to fire hazards.
Clogged Air Filters
The air filter is one of the most commonly forgotten parts of your furnace. Yet, neglecting to change it can be dangerous.
Dust and dirt will gradually clog the air filter (as it should), but you need to remember to have it changed roughly every three months. A clogged air filter will restrict airflow, leading to lowered efficiency, overheating, and possibly carbon monoxide leaks.
Dirty Gas Burners
Over time, the gas burners will gather soot and dirt. This can cause them to burn the fuel at lower temperatures, and that will affect the efficiency of your furnace. It can also prevent the furnace from working properly at all.
If the flame coming from the gas burner is orange or red rather than blue, it’s an indication that the gas burners need cleaning.
There’s no time where the smell of gas around your furnace is something you should ignore. If you smell gas in your home, leave the house first and then call a professional immediately. They’ll instruct you on how (or if) you should attempt to turn off the gas from outside your home and what other steps to take.
There are times where you may smell some gas around the furnace and find that it’s harmless. The real threat is when you smell gas coming from the air vents because that indicates a cracked heat exchanger. Regardless, we suggest calling a professional instead of guessing at what the problem might be.
