However, as temperatures start to fall and Milton residents begin using their gas furnaces for the first time in months, complaints about heating systems tend to arise. Bedding down for the winter also means getting cozy with your furnace again, which, after a summer of inactivity, may be suffering from various performance issues that impact comfort, efficiency, and even safety. Knowing what the usual furnace issues are that occur during the first cold snap could help keep you toasty and save you from expensive repairs this winter.
1. Furnace Won’t Turn On
One of the most annoying issues is when your furnace won’t turn on. This problem can be as minor as a flipped circuit breaker or a malfunctioning thermostat. At times, it may be due to a dirty flame sensor or ignition failure as well. Before you panic, check your thermostat settings, confirm that the furnace switch is turned on, and replace the batteries if necessary. If the issue persists, consider contacting a professional to inspect the system in person.
2. Strange Noises or Odors
When you fire up a furnace that has sat idle for months, strange noises (banging, rattling, or squealing) can develop, and even a burning smell is not out of the question. Although a faint scent and some noise are to be expected when dust burns off, constant smells or noises might be a sign of more serious problems, such as loose parts, motor issues, or even a cracked heat exchanger. These types need to be repaired immediately to prevent further harm and ensure the safety of any loved ones.
3. Uneven Heating or Weak Airflow
If some rooms in your home seem colder than others, your furnace may not be circulating warm air evenly throughout the house. This may occur due to blocked air filters, obstructed vents, or leaky ductwork. Your system has to work harder when there is limited airflow, leading to increased wear and tear. Options include replacing the air filter and ensuring that vents are open and unobstructed, which can significantly impact both performance and comfort.
4. Pilot Light or Ignition Problems
Ignition problems are widespread with gas furnaces shortly following the start of the heating season. An obstructed pilot light, a faulty thermocouple, or a failed electronic ignition can be the reason your furnace has trouble igniting and maintaining its fire. Because these are gas components, they must be inspected and repaired by a licensed technician for safety reasons.
5. Blower Motor Malfunctions
The blower motor distributes warm air throughout your home. If it’s dirty, worn, or has trouble starting, you might experience weakened airflow or strange sounds. Routine tasks, such as lubrication and cleaning, can help save you money by preventing motor burnout.
6. Thermostat Calibration Issues
At times, the issue with a furnace isn’t the furnace itself; it’s the thermostat. If your home isn’t reaching the desired temperature, your thermostat may be getting an inaccurate sense of indoor conditions. Re-calibrating or upgrading to a smart thermostat can restore that accuracy, along with improved energy savings, and maintain reliable comfort.
7. Dirty Filters and Blocked Intakes
A dirty furnace filter is the simplest yet most frequent reason for inadequate heat performance. Dirty filters block airflow, forcing your furnace to work harder and putting it at risk for overheating. Every 1 -3 months, you should change your filter for cleaner air and energy efficiency.
