“The weather outside is frightful.” That’s when you’re glad you had your central heating system in New Jersey checked and serviced in the autumn.
It’s a good feeling to know that it may be rainy, freezing, blizzardy, windy horrible weather outside, but that you’ve got your own comfortable ‘weather’ inside.
But… what if you can tell that there’s something wrong with your furnace? Maybe you can hear the thermostat click, the furnace starts up, you’re all ready for some toasty warm air, and then… it just shuts down. Or maybe you wake up and you can see your breath. Not good.
But don’t worry! Mark Lindsay and Son Plumbing & Heating has you covered! Here are 5 things that you should check before calling one of our trusted HVAC contractors in West Milford. Of course if you have any questions, or still need help, don’t hesitate to give us a call!
Start with the most straightforward step—your thermostat. Incorrect settings are often the culprit.
✅ Quick Tip: For programmable or smart thermostats, reset them to factory settings and see if that resolves the problem.
A clogged air filter can restrict airflow, overheat your West Milford furnace, and shut down the heating system.
✅ Why this matters: A clean air filter not only helps your furnace function properly but also improves indoor air quality.
If your heating system isn’t turning on, it may not be receiving power.
✅ Safety Reminder: If the breaker trips repeatedly, there may be an electrical issue requiring professional attention.
For gas furnaces, the pilot light or ignition system is crucial.
For oil or propane systems, a lack of fuel can stop your heating system from functioning.
✅ Pro Tip: Schedule regular fuel deliveries to avoid running out unexpectedly during cold weather.
If you’ve worked through these steps and still have no heat, it’s time to call an HVAC professional. Issues like malfunctioning components, faulty wiring, or broken parts may require expert diagnostics and repair.
This could indicate a dirty air filter, blocked vents, or a problem with the blower motor.
Schedule professional furnace maintenance annually—ideally before the heating season begins—to ensure your system runs efficiently.
With proper maintenance, most furnaces last between 15-20 years.
This issue, known as short cycling, can be caused by a dirty air filter, a malfunctioning thermostat, or an oversized furnace. Start by replacing the air filter and checking the thermostat settings. If the issue persists, it may require professional attention to prevent damage to your furnace.
Unusual sounds like banging, screeching, or rattling often indicate an issue:
– Banging: Could signal delayed ignition or expanding ducts.
– Screeching: Likely a worn-out blower belt or motor bearings.
– Rattling: May mean loose panels or components.
If you hear these noises, turn off the furnace and call our HVAC technicians to avoid further damage.
Consider replacing your furnace if you notice these signs:
– Age: Furnaces typically last 15-20 years.
– Rising energy bills: Older, inefficient furnaces consume more energy.
– Frequent repairs: If repair costs are adding up, investing in a new unit may save money long-term.
– Uneven heating: If some rooms are colder than others, your furnace may be struggling.
