Why You Should Check Your Air Conditioner in Winter: Avoiding Carbon Monoxide Risks

As winter approaches, many homeowners may think their air conditioning (AC) system can be forgotten until the warmer months return. However, neglecting your HVAC system during the colder season can lead to dangerous risks, particularly the buildup of carbon monoxide (CO), a colorless, odorless gas that can be deadly if not addressed.

Here’s why it’s important to keep your AC in check, even when it’s not being used for cooling.

What’s the Link Between HVAC Systems and Carbon Monoxide?

While carbon monoxide is typically associated with heating systems, it can also pose a threat through malfunctioning air conditioning units. Many HVAC systems, especially those with a furnace or gas-powered components, are responsible for venting gases like CO outside. If something goes wrong with these components—such as cracks in the heat exchanger or blockages in the exhaust system—carbon monoxide can leak into your home.

This is particularly dangerous in the winter when people are indoors, relying on their heating system to stay warm. Without proper ventilation, this invisible gas can accumulate, putting you and your family at risk.

Why should you check your HVAC heating in Winter?

Winter is the ideal time for an HVAC check-up. Though the system is not cooling, it may still be running for heating, meaning there is a greater chance of wear and tear. Here’s what can go wrong:

Heat Exchanger: Over time, heat exchangers in your furnace or HVAC unit can crack. If this happens, carbon monoxide may leak into the air you breathe.

Blocked Vents and Exhausts: Snow, ice, and debris can block your system’s vents, preventing gases from escaping properly. A blocked vent may force carbon monoxide back into your home.

Malfunctioning Safety Features: Some systems are equipped with CO detectors, but if these sensors aren’t working or have become clogged, they may not alert you in time to a dangerous situation.

What does a heating inspection include?

To prevent carbon monoxide leaks and ensure your system is running smoothly, it’s essential to schedule an inspection with a professional technician.

Inspection for CO Leaks: Technicians will test your system for the presence of carbon monoxide, ensuring there are no leaks.

Check of Heat Exchanger and Components: The technician will look for cracks, rust, or other damage to your system’s heat exchanger, which could allow CO to escape.

Cleaning and Clearing: Blockages in vents and exhaust pipes are removed to ensure proper airflow.

Calibration of Sensors: Properly functioning CO detectors and system sensors will be checked to ensure they will trigger an alarm if needed.

Simple Tips for Winter Safety

In addition to scheduling a professional inspection, there are steps you can take to protect your home:

Install Carbon Monoxide Detectors: These are crucial for detecting dangerous CO levels in your home. Make sure they are placed near sleeping areas and tested regularly.

Keep Vents Clear: Ensure that nothing is blocking the outdoor vents and exhaust pipes of your HVAC system.

Change Filters Regularly: Dirty air filters can reduce airflow and cause system strain, increasing the likelihood of breakdowns or inefficient operation.

Conclusion: Don’t Wait for a Problem to Arise

While it’s easy to overlook your HVAC system during the colder months, a little maintenance can go a long way in preventing serious risks like carbon monoxide poisoning. Scheduling a winter inspection ensures your system is safe, efficient, and ready to keep you warm throughout the season. Take action now to protect your home and family from the dangers that could be lurking in your HVAC system.

Your peace of mind is worth it.
