3 Reasons Why Your Oil Burner Isn't Blowing Hot Air

Does your home rely on an oil burner for heat? Is that burner working, but not blowing sufficient hot air through your vents? Insufficient heat can be frustrating, especially if you live in an extremely cold climate. Fortunately, solving this problem usually isn't too difficult. You may need to replace a part or make a slight adjustment to the heater. However, the fact that the burner is working is a good sign. Here are three steps to troubleshoot your oil burner and find a solution:

Check the filter. The simplest answer is that the burner's filter is too dirty. The filter serves an important purpose in keeping dirt, grime, and other contaminants out of your airflow. However, if you don't change the filter regularly, it will become covered in dirt and that will keep hot air from passing through. Your burner may be blowing air, but the air isn't making it past the filter.

Fortunately, there's an easy fix. Simply replace the filter. You can find one at any hardware store. After you've replaced the filter, wait a bit and then check some vents to see if the air feels warmer. If it does, you've fixed the problem. If not, you'll need to move on to another step.

Inspect the air ducts. It also may be possible that your burner isn't broken at all. Instead, it could be the duct work. This is especially true if there only seems to be a lack of air from certain vents. Check each vent to identify where there is insufficient air. Then follow the duct work from that vent to see if there are gaps where air is leaking out. You may need to have the ducts sealed up or even have sections of duct work replaced. A furnace or duct service company could help you figure out a solution to the issue.

Examine the fan belt. Finally, the problem could be that the burner's fan belt is damaged. Your burner has a fan that is driven by a belt. The fan is responsible for blowing the hot air up into the ducts. However, if the belt is cracked or broken, then it won't drive the fan at a proper speed. It may not even work at all. You can take a look at the fan and fan belt by opening the front panel to the burner. The fan should be readily apparent, with the belt connected to it. Examine the belt for any cracks or other damage.

If none of these steps work, or if  you're not comfortable doing them yourself, contact an oil burner service company like Shearman Oil Inc or others. They can come out and inspect your burner and recommend a solution.
