What To Do Before Requesting Service

One of the great things about heating your home with our Bioheat® SuperPlus™ is that it gets your home warm faster, comparatively, than any other fuel source.

But once your home gets warm, your furnace shouldn’t keep running. If it does, that’s a problem. It’s inefficient and will drive up your heating costs. Your furnace constantly running will also cause more wear and tear on the parts inside it, setting up a potential breakdown down the line.

If you’re facing this problem, the trained, experienced service technicians at Cubby Oil are here for you. We show up on time and get the job done right the first time.

But before you call us, there are some troubleshoots you can do. A little detective work can have your furnace running properly again without the cost of a service call! Here are three areas to check.


What is the temperature setting on your thermostat? Settings in the upper 70s or into the 80s make the furnace is going to run for a much longer time to reach and sustain those temperatures.
The U.S. Department of Energy recommends setting your thermostat at 68˚ Fahrenheit when you are at home. Your home will still be comfortable, and you’ll save on heating costs.

Air Filter

If it’s been more than a month since you changed the air filter, check it right away. Clogged air filters reduce the air flow through your furnace. Heated air is not reaching your living spaces. Your furnace will be forced to run longer and cycle on more frequently. The dirty air that does get through the filter can also damage the parts in your furnace.

Set a reminder on your calendar to check your air filter once a month. Do it more frequently if you have pets, or if someone in your home has allergies or a respiratory problem.

Blower Motor

Check the air coming out of the vents. Is it warm? Then both the furnace and blower are running. Is it cool or cold? That means only the blower is running. If the latter is the case, check to see if your thermostat is set to “on” and not “auto.” It is set to “on,” switch it to “auto” and see if the problem clears up.

Give the thermostat a closer look if this doesn’t do the job. There may be a wiring problem or worn batteries. If changing the batteries doesn’t work, you will likely need a new thermostat.
