As temperatures in Markham drop, the last thing you want is a furnace that doesn’t work when you need it most. When your furnace acts up, you’re left with a cold home and the frustration of figuring out what’s wrong. Here’s a guide to some common furnace issues, possible reasons behind them, and why it’s often best to reach out for Furnace Repair Markham services when the time comes.
1. Furnace Won’t Turn On
One of the most annoying issues is when the furnace just won’t start. Here’s what could be going on:
- Thermostat Settings: Sometimes, the thermostat might simply be set wrong. Double-check that it’s set to “heat” and above the current room temperature. If this doesn’t work, it might need a deeper check by a professional.
- Power Supply: Check if the furnace has power. Look at your circuit breaker to see if it’s tripped, or check the furnace’s power switch. If power seems fine, there may be a wiring issue, which a technician can help resolve.
- Ignition or Pilot Light Issues: Older furnaces have a small pilot light that sometimes goes out and needs relighting. Newer models have electronic ignitions that can also fail. If this is the problem, it’s often best to let a repair professional handle it.
If the furnace won’t start and these quick fixes don’t help, calling Furnace Repair Markham can get it running again.
2. Furnace Not Heating Enough
If the furnace is on but still not heating your home properly, you might be dealing with:
- Clogged Air Filters: When air filters are clogged, airflow becomes restricted, causing the furnace to work harder than it should. Try replacing or cleaning the filter.
- Blower Motor Problems: The blower motor is what moves warm air through your home. If it’s not working properly, airflow will be weak or cool. You’ll likely need a professional to repair or replace the motor.
- Ductwork Leaks: Leaks in your ducts mean that warm air escapes before it reaches your rooms. A technician can inspect and seal any leaks, helping your furnace heat your home more efficiently.
3. Strange Noises
A furnace isn’t supposed to be loud. If you’re hearing strange sounds, here’s what they could mean:
- Banging or Popping: This often happens when there’s a buildup of gas in the furnace before it ignites. It’s a serious issue that needs immediate attention. A repair expert can check and adjust the burners and ignition.
- Squealing or Whining: High-pitched sounds usually mean a worn-out belt or blower motor parts that need lubrication or replacing. A quick call to a repair service can address this.
- Rattling or Rumbling: Loose parts in the furnace can cause rattling, while a steady rumble may point to burner issues. A technician can tighten components and inspect the burner to quiet things down.
Strange sounds are usually a sign it’s time to search for Furnace Repair Markham to avoid further issues.
4. Furnace Keeps Turning On and Off
If your furnace is cycling on and off constantly, it could mean:
- Overheating: A furnace will automatically shut off to prevent damage if it’s overheating, often due to restricted airflow from a dirty filter. Clean or replace the filter to see if this helps.
- Thermostat Issues: A faulty thermostat can cause the furnace to cycle too often. If adjusting it doesn’t solve the problem, it might need replacement.
- Limit Switch Problems: The limit switch monitors furnace temperature and tells it when to turn off if it gets too hot. A broken limit switch can cause your furnace to turn off too soon. A technician can test and replace it if necessary.
Short cycling wastes energy and can damage your furnace, so reaching out for help from a local service is a smart move.
5. Furnace Blows Cold Air
If your furnace is only blowing cold air, the cause might be:
- Pilot Light or Ignition Issues: A gas furnace relies on either a pilot light or an electronic ignition to heat air. When these fail, your furnace blows cold air. A technician can clean or replace the necessary components.
- Thermostat Setting: Check if the thermostat is set to “auto” instead of “on.” The “on” setting keeps the blower running constantly, even when it’s not heating. Switching to “auto” allows it to blow only warm air.
- Leaking Ducts: If there are leaks in your ducts, cold air may get mixed in, leading to cool air blowing from the vents. Sealing leaks can fix this issue.
If the furnace continues to blow cold air, reaching out to a Furnace Repair Markham professional can help solve the issue quickly.
6. Furnace Smells Funny
Odd smells coming from your furnace could be a warning sign. Here’s what they might mean:
- Burning Dust: A dusty smell is normal when you turn on the furnace for the first time in a while, as it burns off accumulated dust. It should go away quickly.
- Gas Smell: If you smell gas, turn off the furnace and leave the house immediately, as this could indicate a dangerous leak. Contact your gas company, then follow up with a furnace repair service once the issue is contained.
- Musty Smell: A musty odor often means mold or mildew in the ductwork. A professional cleaning can resolve this problem.
If the smell doesn’t go away or seems dangerous, don’t wait—call Furnace Repair Markham” to have a professional check it out.
