Regardless of how advanced or pricey your furnace is when you bought it, the fact remains that it’s not designed to last forever. But for the most part, furnaces can last 15 years before major problems start surfacing. 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 forgot to have your furnace serviced in a year or even longer.
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. 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. You probably wouldn’t be that concerned if the leak is water; but if it’s gas or oil, now that’s doubly serious. The most obvious sign of a leak is pooling near or underneath the furnace. It is important that you call in a qualified furnace repair technician right away if there is a leak because it could be your condensate line failing or clogging, which eventually will result to the furnace’s inability to produce heat.
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. Open the furnace and find the gas supply valve and make sure this is turned off, too. You never should turn the lights off or light matches as you patiently wait for the furnace repair technician to arrive.
4 – If your utility bills suddenly increase without any apparent reason.
Lastly, in case you see a sudden spike in your utility bills, it could mean that your furnace is working harder than usual to produce heat inside your home, which in turn relates to the use of 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.
