Regardless of how advanced or pricey your furnace is when you bought it, the fact remains that it’s not designed to last forever. In most instances, furnaces are meant to last 15 years. But you only can achieve that through proper and regular maintenance.
Now if you plan on taking advantage of your furnace for as long as it’s possible, then you at least have to understand and learn the signs that it needs repairs; and with that skill, you’d be able to know when to call in a qualified service technician to fix it for you.
1 – You haven’t serviced your furnace for a year or two.
Can you figure out when was the last time you called a professional to examine or inspect your furnace? If you no longer can trace back the time when you had your furnace checked, it only means that it needs to be subjected to a comprehensive inspection immediately. 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 is 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 – You smell leaking gas.
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 thing you must do is shut the furnace down the soonest time possible. Next, you need to find out where the gas supply valve is inside your furnace to turn it off. Never turn the lights on or light any matches or candles while you wait for the furnace repair expert 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. The only way to figure out if there is a problem with the furnace, causing it to work hard is by calling in a qualified service technician.
