Winters in South Central PA can be cold, so having a reliable furnace to get you through those months is important. One of the worst things you can do is delay annual furnace maintenance, only to find that when winter arrives, you’re left without heat when you need it most. The best time to schedule a furnace or HVAC inspection is just before winter hits, which is typically in the fall.
Let’s look at five signs your furnace needs repairs before winter.
Your Furnace Is Making Strange Noises
If you’re hearing banging, popping, or whistling noises, that’s usually not a good sign. These signs could point to expanding and contracting air ducts or a dirty burner that’s delaying ignition. Loose screws or panels inside your system can also cause issues if ignored. You may also have a motor issue or a worn belt. Whatever the problem could be, it’s wise to call for an inspection, especially if you’re hearing these noises.
Don’t ignore unusual furnace noises. If you are hearing these types of sounds in your home, it is time to schedule an HVAC inspection.
Uneven Heating Throughout Your Home
Are there certain rooms in your house that feel colder or hotter than others? Uneven heating is a sign that your HVAC system isn’t working correctly. This issue can stem from a few different problems:
- A faulty thermostat
- Leaky or poorly insulated ductwork
- Clogged or dirty air filters
If your furnace is working, but the temperature in your home is inconsistent, it is time for a professional furnace inspection.
Rising Energy Bills
If your energy bills suddenly increase, it could be a sign that your furnace is working inefficiently and has to use more energy to maintain a comfortable home. This extra work leads to higher energy bills. Some common causes include:
- Dirty air filters
- Leaks in the ductwork
- Buildup inside the furnace
- Worn-out components
A furnace tune-up can make a big difference in efficiency and monthly energy bills.
Musty or Burning Smells When the Heater Runs
Have you noticed musty or burning smells when your heat kicks on?
- Musty Smells may indicate mold or mildew growing in your ducts or within the unit.
- Burning smells could be a sign of electrical problems, dust buildup, or overheated parts.
Both can impact your air quality and health, making it critical to get them checked immediately.
Your Furnace Keeps Turning On and Off (Short Cycling)
Does your furnace start, run for a minute or two, then shut off, and repeat this cycle? That constant cycling on and off, known as short cycling, is a sign that your system isn’t running as efficiently as it should.
Short cycling can:
- Waste energy
- Significantly reduce your furnace’s lifespan
- Make your home uncomfortable
Short cycling can occur if your air filter is clogged, your thermostat is broken, or there’s an issue with the unit’s airflow.
