No matter how advanced, sophisticated, or expensive your furnace is, in reality, it never will last forever. In most instances, furnaces are meant to last 15 years. However, your furnace wouldn’t last that long if you don’t know how to properly and regularly maintain it.
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 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? The fact that you no longer can determine when’s the last time you have it checked only means that your furnace needs to be inspected for major problems right away. The lack of inspection could even mean that you have not changed your filter for a very long time.
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. You probably wouldn’t be that concerned if the leak is water; but if it’s gas or oil, now that’s doubly serious. As for the case of water leaking, the most obvious sign is pooling near or under the furnace. You need to have it checked right away because your condensate line might be clogged, which in turn could lead to the inability of your furnace to keep your living space warm and comfortable.
3 – There’s a smell of glass leaking.
Luckily, it’s very easy to detect a gas leak because you will immediately smell gas. First of all, you need to prevent a major accident from happening by shutting the furnace down right away once you realize there’s a leak. 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.
