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 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. 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 always will be prone to leaks, and it could either be oil, gas, or 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. 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 – 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. You then will have to open up the furnace to find the location of the gas supply valve; this is important because you likewise have 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 – 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. To identify what’s causing the furnace to work hard, you need to call in a qualified service technician to do a comprehensive check.
