You rely on your furnace to keep your home comfortable and warm when the weather turns cold. However, when heating system problems arise in freezing temperatures, they aren’t just a nuisance—they put you at risk for hypothermia and other health complications.
Having your furnace checked regularly can help prevent sudden breakdowns. Learning to recognize the warning signs of a furnace problem means you can also seek help soon to avoid bigger issues. Here, we describe common signs of a broken furnace and provide furnace maintenance tips. If you notice any of these issues, contact Davis Heating & Cooling for reliable furnace repair in Central and South Jersey.
1. Unusual Noises
Strange noises are a common indication that your furnace is experiencing problems. A soft and steady hum while the furnace is running is normal—banging, rattling, or squealing is not. If you hear any sudden or loud noises, they should be checked immediately.
The cause of unexplained noises could be loose components, motor issues, or ignition system problems. An experienced technician can diagnose the source of the problem and offer options to repair or replace your system.
2. Weak or Inconsistent Airflow
If your furnace has clogged filters or blower motor issues, then you may start to notice signs of inefficient heating. These include weak air coming from the vents or uneven heating in rooms. This could include cold spots within rooms or in certain areas of the house that aren’t getting warm air. General wear that happens over time, along with issues with air ducts, are additional culprits for poor airflow, which is another reason you should have your furnace maintained every year.
3. Strange Odors
Contact an expert for furnace repair services if you notice any new or unusual odors like burning or musty smells. These odors may indicate that you have dust buildup, which can negatively impact indoor air quality or even cause electrical problems. Gas-like smells should always be taken seriously as a gas leak is dangerous and requires expert intervention.
We recommend that anyone with a furnace also install carbon monoxide detectors in their home. This gas is odorless but can be deadly.
4. Frequent Cycling
If you start to notice that your furnace is short-cycling, or turning on and off more frequently than normal, it’s time to get it looked at. A faulty thermostat, dirty filters, or airflow restrictions can all cause frequent cycling. Heater tune-ups each year can help keep your furnace running smoothly, but you should always schedule an appointment quickly if your furnace starts to show signs of wear or damage.

FAQs
How often should I schedule furnace maintenance?
You should have your furnace serviced at least once yearly, ideally in the fall before winter begins. Regular maintenance appointments help to ensure your furnace runs efficiently. Besides changing dirty air filters and cleaning coils and other components, your technician will also identify minor issues before they become big problems.
Can I fix furnace issues myself?
Most furnace repair work requires the expertise of a licensed technician from a reputable HVAC company to ensure safety. Furnace repair often involves gas lines and electricity, which are dangerous if you don’t have the necessary training.
What should I do if I smell gas near my furnace?
If you smell gas, immediately evacuate your home and contact the gas company and emergency services. Never attempt to fix a potential gas leak on your own.
How long does a typical furnace last?
A furnace lasts between 15 and 30 years. The actual lifespan depends greatly on the type of furnace and the maintenance it receives.
Is it normal for a furnace to make noise?
A quiet humming sound is generally normal, but you should have your furnace checked if it makes any new or loud sounds.
