How to Spot Carbon Monoxide Risks in Your Home: February Furnace Safety Guide

With the winter chill lingering in Woodstock, ON, and the surrounding areas like Ingersoll, London, and Stratford, your furnace likely works overtime to keep your home warm. However, heightened furnace use in February can increase the risk of carbon monoxide exposure—a silent, odorless gas that’s a potential danger in any home with fuel-burning appliances. At Lloyd’s, your local HVAC specialists servicing Woodstock and neighbouring communities, we’re dedicated to making sure your family stays safe and comfortable during heating season. 

Here’s your essential guide to spotting carbon monoxide risks and keeping your loved ones protected.

Why Is Carbon Monoxide a Winter Concern?

Carbon monoxide (CO) is especially hazardous in colder months. Homes remain sealed to retain warmth, limiting ventilation and allowing gases to build up if there’s a problem. Whether you live in Brantford or Stratford, furnaces, fireplaces, and other heating equipment can all be sources of CO leaks. Regular professional maintenance—from Carrier Factory Authorized Dealers like Lloyd’s—reduces these risks, but understanding the warning signs is equally vital.

Signs You Might Have Carbon Monoxide Issues

Spotting potential CO risks isn’t always straightforward, but there are telltale clues both homeowners and business owners should know:

• Stale or stuffy indoor air, especially when the heating is running
• Frequent headaches, dizziness, nausea, or unexplained fatigue among family members 
• Yellow or flickering furnace burner flames instead of blue (seen through the furnace’s inspection window)
• Excess moisture on windows (a sign of poor ventilation)
• Soot or scorch marks around heating appliances 
• An unusual pilot light that keeps going out or needs frequent relighting.

What Causes Carbon Monoxide Leaks From Furnaces?

Many homeowners ask: "Can a furnace leak carbon monoxide without producing any odor?”

The answer is yes—CO is colourless and odorless, making professional inspections crucial. Common sources of leaks include:

• Cracked or rusted heat exchangers 
• Blocked or improperly vented flue pipes 
• Faulty furnace installation or maintenance 
• Defective or aged gas burners

If you live in Woodstock or a nearby town within a 50–100 km radius, scheduling an annual furnace service is a must for peace of mind. At Lloyd’s, we offer comprehensive furnace repairs, tune-ups, and safety checks to prevent issues before they escalate.

How to Maximize Furnace Safety This February

Staying proactive is key—late February is the ideal time to check your furnace as cold snaps persist and furnaces have endured months of heavy use. Here’s a simple, actionable checklist for families in Southwestern Ontario:

Regular Maintenance:

• Book annual furnace inspections with a trusted, NATE-certified local technician 
• Ensure your carbon monoxide detectors are functioning and have fresh batteries
• Clean or replace your furnace filter monthly for optimal airflow. 

Visual Inspections:

• Look for visible damage, corrosion, or debris buildup 
• Test smoke and CO alarms in every sleeping area and main hallway
• Keep vents and registers unobstructed by furniture or drapery. 

Local Tip: If you own a fireplace or use a wood stove in addition to your furnace, have those inspected too—especially after heavy winter use.
