Issues with heating systems are reality, and most people having a heating system in their home experienced them at one time or another. However, many of these are just minor kinks that most of us can fix on our own, saving time and money. So, before you call a certified technician, make these important checks to see if the problem can be fixed easily or not.

1. Is your furnace actually ON?

The furnace’s on switch is not the only thing which needs to be turned on. It is usually connected to an emergency switch which is on the wall and usually looks like a common light switch. And once you make sure there’s power coming to the furnace, you should allow up to few minutes for it to start running. Heating systems which use forced air may also feature a separate switcher for the air blower.

2. Thermostat Settings

Obviously, if everything looks fine, but the furnace is still idle despite the fact that it’s cold in your home, you may need to check the thermostat. Even if you have a smart thermostat it doesn’t mean it will always “think” like you, or may have an issue with wiring and power.

3. Is there enough fuel oil in your tank?

Oil powered furnaces should not be working if oil level is below 25% of the tank capacity. You should monitor your tank oil level as often as possible, should you get an insight in your actual consumption and perhaps detect some problems such as a hidden oil spill or some other problem with the tank.

4. Are Filters Clogged

All oil furnaces, just like cars, have fuel filters. Heating oil fuel filters can be clogged by particulates from oil. . This is more likely to happen when you use oil from the tank bottom or low quality oil. Additionally, if you use a forced air furnace, there are air filters as well. These can be clogged by dust and other environmental agents, diminishing the heating efficiency of your system.

5. Blown Fuse

If there is no power in your system at all, the first thing you should look at is your home fuse box. Fuses occasionally burst, leaving no signal, such as sound, and remain undetected until you check them. Fuses have small windows on their tips, which help you determine if it’s blown – if the window is grayed or you see melted metal it needs to be replaced. Bring the broken fuse to the hardware store to make sure you will buy the right replacement.

6. Furnace Age

Although oil furnaces are known to be lasting and perhaps the most durable among all heating solutions, these aren’t made to serve for an eternity. If your furnace or boiler consumes more heating oil for the same amount of heat than before, it’s losing efficiency and you can consider replacement. Remember that new furnaces are much more efficient than your old one ever was, so this investment will pay back relatively quickly.
