One issue that HVAC system owners may face is that they may find that their oil furnace bangs when starting up. A variety of factors can cause this. For many homeowners, their oil furnace is the heart of their HVAC system. 

Not only does it provide warmth during the winter months, but it also helps circulate air and regulate humidity levels.  However, oil furnaces can sometimes develop issues that can be both frustrating and costly to fix.

So What Are The Common Issues An Oil Furnace Can Have

If your oil furnace bangs when starting up it’s usually because the filter is dirty, the vents are closed, or there’s an obstruction in the ductwork.

Additionally, the oil furnace itself may need to be cleaned or replaced. Another common issue is oil furnaces shutting down prematurely. A faulty oil filter, a clogged fuel line, or a problem with the oil pump can cause this. Significant oil leaks indicate a problem with the oil pump or delivery system.

So it’s important to be on the lookout for any possible sign your HVAC system might be giving out when something is off. 

Signs You Should Change or Give Maintenance to Your Oil Furnace

Like any other appliance, furnaces require regular maintenance to function correctly. Here are some signs you need to give it care or replace it:

  • Your energy bills are going up: If you’re suddenly paying a lot more to heat your home, it could be due to inefficiency in your furnace. Older furnaces are less efficient than newer models, so if that is happening, it might be time for an upgrade.


  • The furnace is making noises: If your furnace starts cracking, popping, or banging noises, it could be due to a problem with the heat exchange. 


  • The stove isn’t heating evenly: If some rooms in your home are much warmer or cooler than others, it could indicate a blockage in the ductwork. 


  • You see rust or water around the furnace: Rust or water around the furnace is never a good sign. It could be due to a problem with the condensation drain or a leaking oil line.
