No matter how advanced, sophisticated, or expensive your furnace is, in reality, it never will last forever. For the most part though, a furnace is expected to last 15 years before you develop headaches due to constant repairs. But you only can achieve that through proper and regular maintenance.
If you want your furnace at home to reach the maximum lifespan it is built for, then you should at least learn the signs that a repair is needed; obviously, you don’t have to do the fix yourself as you always can call a professional service technician to do that for you.
1 – You failed to have your furnace serviced for a year.
Can you figure out when was the last time you called a professional to examine or inspect your furnace? So, if it already is impossible to determine when was the last time you had you furnace checked, then it only means one thing: you need to have it checked and fixed right away. Because you haven’t allowed any inspection for a very long time, it means you also might haven’t replaced your filter for quite a long time already.
2 – There’s water pooling around the furnace.
Furnaces, as advanced and well-built they are, will eventually have leaks, and it could be oil, gas, or water, depending on the fuel your heating system uses. Obviously, there’s little concern if water is leaking; but the same cannot be said when it comes to gas or oil. The most obvious sign of a leak is pooling near or underneath the furnace. It’s very important for you to call a qualified furnace repair technician once you observe there’s a leak because there’s a big possibility that the condensate line is clogged or damaged.
3 – There is that dangerous smell of gas leaking.
While a gas leak that remains undetected is very dangerous, it is seldom ignored because once it leaks, the smell is apparent and obvious. The first step in preventing a major accident is to shut down the furnace the moment you figure out there’s a leak. Next, you need to find out where the gas supply valve is inside your furnace to turn it off. Be reminded that lights shouldn’t be turned on during a leak, more so that of lighting a match while you’re waiting for the local furnace repair technician to arrive.
4 – If your utility bills suddenly increase without any apparent reason.
Lastly, if you feel like you utility bills have increased quite significantly, there’s a good chance that it’s because of your furnace not being in tiptop condition, forcing it to work harder and use more fuel than usual. To identify what’s causing the furnace to work hard, you need to call in a qualified service technician to do a comprehensive check.
