Regardless of how advanced or pricey your furnace is when you bought it, the fact remains that it’s not designed to last forever. For the most part though, a furnace is expected to last 15 years before you develop headaches due to constant repairs. But then again, there’s no way your furnace will last that long if you don’t value 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 failed to have your furnace serviced for a year.
Can you recall the last time you called a qualified HVAC technician to 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 – 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 a leak is pooling near or underneath 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. Open the furnace and find the gas supply valve and make sure this is turned off, too. 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 – You observe that your most recent utility bill has increased without doing anything different the last time.
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.
