We are especially thankful for the comforts of home when it’s extremely cold, snowy, or icy outside. While built to withstand the cold temperatures, extreme weather conditions can impact your furnace over time, leading to increased wear and tear that requires furnace repair, and even premature failure requiring replacement. Preventing the untimely need for furnace service is one of the top reasons it’s so important to keep your scheduled preventive maintenance appointments.
How Freezing Temperatures Impact Your Furnace
When temperatures plummet, your furnace must work harder to maintain a comfortable indoor environment. This extra strain can result in:
Ignition or Pilot Light Problems – If the ignition system fails, your furnace won’t generate heat. Ignition system failures may be due to a faulty ignitor, thermocouple issues, or pilot light malfunctions.
Clogged or Dirty Air Filters – A clogged filter restricts airflow, making the furnace work harder and possibly causing overheating or short cycling.
Faulty Thermostat – A malfunctioning thermostat can prevent the furnace from cycling correctly or maintaining a consistent temperature.
Blower Motor Issues – If the blower motor fails or slows down, your furnace won’t circulate warm air efficiently, leading to cold spots in your home.
Cracked Heat Exchanger – Extreme cold and continuous operation can cause heat exchanger damage, which can be dangerous as it may lead to carbon monoxide leaks.
Frozen or Blocked Exhaust Vents – Snow and ice can block the furnace’s intake or exhaust pipes, causing the system to shut down as a safety precaution.
Condensate Line Blockage – High-efficiency furnaces produce condensation that must drain. If the line freezes or gets clogged, the furnace may shut down.
Worn-out Bearings or Belts – The mechanical components of a furnace, such as belts and bearings, can wear out over time, causing strange noises and reduced efficiency.
Gas Supply Issues – Low gas pressure or leaks can prevent proper furnace operation, leading to inconsistent heating or failure to start.
Electrical Component Failures – Wiring issues, sensor malfunctions, or circuit board failures can prevent the furnace from operating correctly.
Signs That Your Furnace is Struggling in Extreme Cold
Even if your furnace is still running, warning signs of trouble can indicate that it’s not operating efficiently or is on the verge of failure. Be on the lookout for:
- Frequent cycling: If your furnace turns on and off more frequently, it may be overworking due to clogged filters or struggling to meet demand.
- Uneven heating or system failure: Older furnaces or systems with neglected maintenance may struggle to distribute heat evenly, resulting in cold spots in your home, potentially leading to breakdowns.
- Strange noises: Rattling, banging, or screeching sounds might indicate loose or failing components.
- Higher utility bills: A sudden increase in heating costs could mean your furnace loses efficiency.
Preventive Maintenance: The Key to Furnace Longevity
The best way to ensure your furnace can handle extreme weather is by taking proactive steps throughout the year. Consider these essential maintenance tips:
1. Schedule Regular Furnace Inspections
Annual maintenance ensures your furnace is in peak condition. A professional technician will:
- Check and clean components to prevent breakdowns.
- Identify wearing or worn-out parts before they fail.
- Improve efficiency, reducing energy costs.

2. Change Your Air Filters Regularly
A clogged filter restricts airflow, forcing your furnace to work harder than necessary. Change your filters every 1-3 months for optimal performance.
3. Monitor Your Thermostat Settings
Avoid drastic temperature swings that can overwork your furnace. Programmable or smart thermostats help maintain efficiency and reduce strain on your system.
4. Keep Vents and Exhaust Pipes Clear
Regularly inspect outdoor vents for blockages caused by snow, ice, or debris. Blocked vents can lead to dangerous carbon monoxide buildup and system shutdowns.
5. Consider a Preventive Maintenance Plan
Signing up for a furnace maintenance plan can save money and prevent costly emergency repairs. As you prepare your home for winter, ensuring your HVAC system is in top shape helps avoid unexpected failures.
Emergency Preparedness: What to Do If Your Furnace Fails in Extreme Cold
Even with proper maintenance, furnaces can fail when you least expect it. If your system stops working during a cold snap:
- Check the thermostat: Ensure you set it to heat and that the batteries function.
- Inspect the circuit breaker: A tripped breaker may be the culprit.
- Look for blocked vents: Clear snow, ice, or debris around external vents.
- Call for professional assistance: If troubleshooting doesn’t resolve the issue, contact Precision Comfort Systems immediately for emergency service.
