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. 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 recall the last time you called a qualified HVAC technician to 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 – You see water pooling around the furnace.
Every furnace is prone to having leaks, whether it is gas, oil, or even water. 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 the presence of a water leak is pooling near or underneath the surface. 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.
It’s true that a gas leak is an emergency situation, but the good thing is that whenever there’s a leak, it’s very easy to detect because of the smell. 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 – All of a sudden, your utility bills unexpectedly increase.
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. 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.
