Understanding and Fixing Oil Furnace Odors in Cold Weather

As someone who's spent years servicing furnaces across Maine and New Hampshire, I've become quite familiar with the anxiety that comes when homeowners notice that distinctive oil smell from their furnace during cold snaps. Let me share a recent experience that perfectly illustrates this common winter challenge.

My Experience with Winter Furnace Problems in New England

Last January, during one of those bone-chilling New England nights, I received an urgent call from Sarah in Portland. Her furnace had started giving off a strong oil smell as temperatures dropped below zero. This scenario is something I encounter often at Select Chimney Services, and I want to help you understand why it happens and what you can do about it.


Common Causes of Oil Furnace Smells

Over my years of experience providing professional heating services, I've identified several reasons why furnaces might emit oil odors during cold weather:


Types of Furnace Oil Odors

Smell Type Likely Cause Risk Level

Rotten Oil Oil Leak Very High

Safety Concerns and Quick Actions

When you smell oil from your furnace, it's important to stay calm but act promptly. As someone who's handled countless emergency calls, I can tell you that quick action often prevents bigger problems.


"Never ignore an oil smell from your furnace - it's like your heating system sending you a smoke signal for help."

Emergency Response Guidelines

First, check if the smell is getting stronger. If it is, turn off your furnace immediately and contact our emergency team for professional assistance.


Troubleshooting Steps for Homeowners

After years of serving communities across Maine and New Hampshire, I've developed a reliable approach to investigating furnace oil smells.


Cold Weather Impact on Oil Furnaces

Cold weather can affect your furnace in several ways:

First, extreme cold can cause the metal in your furnace to contract, potentially creating small gaps where oil vapors can escape.


Next, colder temperatures often lead to increased system strain as your furnace works harder to maintain comfort.


Professional Furnace Maintenance Solutions

As an experienced professional at Select Chimney Services, I recommend regular maintenance to prevent oil smell issues.
