Why Your Furnace Is Running Non-Stop During Cold NJ Weather
(And What Preventative Maintenance Can Fix)
If it feels like your furnace has been running constantly during this cold New Jersey winter, you’re not imagining things.
We hear this concern all the time in February:
“My furnace never seems to shut off — is that normal?”
Sometimes it is.
Sometimes it’s a warning sign.
Let’s break down why furnaces tend to run longer during extreme cold, when it’s a problem, and how preventative furnace maintenance can help protect your system before the end of winter.
Why Furnaces Run Longer During Very Cold Weather
When outdoor temperatures drop into the teens and single digits, your furnace has to work much harder to keep your home comfortable.
In cold Central New Jersey winters, longer run times can be caused by:
Larger temperature differences between indoors and outdoors
Heat loss through walls, windows, and doors
Dry winter air that makes homes feel colder
Older or stressed equipment nearing the end of heating season
In some cases, longer run times are completely normal. In others, they indicate your system is struggling.
When Non-Stop Furnace Operation Is Normal
Your furnace may be running longer than usual if:
Outdoor temperatures are extremely low
Your thermostat is set significantly higher than outdoor temps
Your system is properly sized and simply keeping up with demand
Modern furnaces are designed to run longer, steadier cycles for better comfort and efficiency.
Longer run times alone are not always a problem.
When Constant Furnace Operation Is a Warning Sign
If your furnace seems to never shut off, struggles to reach the set temperature, or runs loudly or unevenly, there may be an underlying issue.
Common causes we find during maintenance visits include:
Dirty flame sensors or burners
Restricted airflow from dirty filters
Improper gas pressure or combustion issues
Weak airflow due to duct restrictions
Components worn down after months of winter operation
Left unchecked, these issues can lead to breakdowns — often on the coldest nights.
How Preventative Furnace Maintenance Helps
Preventative maintenance is designed to identify and correct small issues before they cause a system failure.
During a preventative gas furnace maintenance visit, we check:
Safe and proper ignition
Combustion performance
Temperature rise and airflow
Burner and flame sensor condition
System controls and safety limits
This helps your furnace:
Run more efficiently
Cycle more normally
Experience less stress
Reduce wear on components
Lower the risk of late-season breakdowns
In short, maintenance helps your furnace finish the winter strong.
Why February Is a Smart Time for Furnace Maintenance
Many homeowners assume maintenance only matters before winter starts. In reality, late-winter maintenance is just as valuable.
By February:
Your furnace has been running for months
Components are stressed
Small issues have had time to develop
A breakdown now is especially inconvenient
A maintenance visit now helps catch problems before they turn into emergency repairs — and helps prepare your system for next winter.
