As a homeowner or business owner in Garden City, NY, your furnace is crucial in keeping your space warm and comfortable—especially during the harsh winters in Nassau County. But like any hardworking system, it needs regular maintenance to stay in peak condition. At Five Star Mechanical, we’ve been helping families and businesses stay warm since 2011, and we know exactly what to look for when a furnace starts showing signs of trouble.
If you’re wondering whether your furnace needs a tune-up, here are some telltale signs that it’s time to call the pros.
1. Your Furnace Is Making Strange Noises
Your furnace should hum along quietly in the background, but if you start hearing banging, clanking, or high-pitched squealing, don’t ignore it. These sounds could mean anything from a loose belt to a failing blower motor. We’ve seen firsthand how a small noise can turn into a costly repair if left unchecked—so if your furnace is getting louder, it’s best to have it looked at sooner rather than later.
2. Uneven Heating – Some Rooms Feel Colder Than Others
Do certain areas of your home or office feel colder than others, even when the furnace is running? Uneven heating is often a sign of dirty air filters, ductwork issues, or a struggling blower motor. If you’re constantly adjusting the thermostat to compensate, your system might be working harder than it should—driving up your energy bills in the process. We can inspect your system to ensure warm air reaches every corner of your space.
3. Your Energy Bills Are Climbing for No Reason
Have you noticed a sudden spike in your heating bills? If you haven’t changed your thermostat settings but your bills are going up, your furnace might be losing efficiency. Over time, dust buildup, worn-out parts, and minor mechanical issues can force your system to work harder—costing you more monthly money. A quick maintenance check from our team can help you pinpoint the issue and restore your furnace’s efficiency.
4. Weak or Poor Airflow from the Vents
If your vents barely push out warm air, it’s a sign that something isn’t right. Weak airflow can be caused by clogged filters, blocked ducts, or a failing blower motor. We’ve helped many local homeowners get their airflow back to normal with simple cleaning or repair—so if your furnace isn’t pushing out enough warm air, don’t wait until it gets worse!
5. Your Furnace Keeps Turning On and Off Too Often
Frequent cycling—when your furnace turns on and off more often than usual—can indicate various issues, from a dirty filter to a faulty thermostat. This constant stop-and-start behavior makes your home less comfortable and puts unnecessary strain on your system. Our technicians at Five Star Mechanical can quickly diagnose the issue and get your system running smoothly again.
6. Unusual Smells Coming from Your Furnace
A musty, burning, or rotten egg smell from your furnace is abnormal. A burning odor could mean dust buildup or an electrical issue, while a rotten egg smell could indicate a gas leak—which is a serious safety concern. If you ever smell gas, turn off your furnace immediately and call a professional. Our team is always ready to respond to emergency situations to keep your home safe.
7. Your Furnace Is Over 10 Years Old
Like any appliance, furnaces have a lifespan—typically around 10 to 15 years. If yours is over a decade old and requires frequent repairs, it might be time to consider a replacement. We always prioritize maintenance and repairs first, but if we see that your system costs you more in the long run, we’ll give honest recommendations about your options.
