WHAT CAUSES LOW HEAT LEVELS IN A FURNACE?

Most homes in Englewood, NJ and surrounding cities use forced-air furnaces for their heat. The air is warmed in the furnace itself, and then distributed through your home via the same system of ducts that carries cool air from your AC in the summer. It’s a simple and effective system, but like any other piece of technology, it can run into trouble from time to time.

Luckily, most of the signs are easy to spot, and while only trained technicians can properly diagnose a problem, you can certainly tell that something is amiss when the heat levels coming out of the air in your vents are not as high as you expect. That means your furnace will need to work harder to do its job, raising your monthly bills and the risk of larger breakdowns in equal measures. The causes can be numerous, which is one of the reasons you need a professional to fix it. But it can include any one of the following:

  • Clogged Burners. Dust, dirt and grit can gum up the heads of the burners, especially over a long summer when the furnace sits unused. For obvious reasons, that means less heat is available when you turn your furnace on.
  • Duct Breaches. A breach in your ducts somewhere will either pull heated air out of the ducts or pull cold unconditioned air in.
  • Clogged Gas Lines. A clog in the gas line causes the same kind of trouble that a clogged burner does: lowering the fuel and reducing the heat in equal measures.
  • Overheating. In the event of a clogged filter or similar obstruction, hot air will back up into the furnace. Depending on the system, it may shut off one or more burners to prevent other components from overheating. In these cases, the lower heat levels are often accompanied by a reduced amount of air flow.
