Why Home Inspectors Test for Carbon Monoxide in a Home
Carbon monoxide (CO) is an invisible, odorless gas that can pose serious health risks if present in your home. Properly testing for carbon monoxide is a critical part of a home inspection, ensuring the safety of your family and the home’s occupants. At Executive Home Inspections in Edmonton, we take CO safety seriously, especially in a city where cold winters mean heavy reliance on heating systems that can be a source of this dangerous gas.
Why Is Carbon Monoxide Dangerous?
Carbon monoxide is produced when fuels like natural gas, oil, wood, or propane are burned. Common household appliances such as furnaces, fireplaces, and water heaters can emit CO if not properly ventilated or maintained.
Exposure to high levels of carbon monoxide can cause symptoms like headaches, dizziness, and nausea. Prolonged exposure or extremely high levels can lead to unconsciousness or even death. This is why testing for CO is an essential step during a home inspection.
How Do Home Inspectors Test for Carbon Monoxide?
Home inspectors use a variety of tools and methods to detect the presence of carbon monoxide and identify its potential sources. Here’s how it’s done:
1. Using Carbon Monoxide Detectors
Home inspectors rely on portable carbon monoxide detectors to measure CO levels in the air. These handheld devices are highly sensitive and provide real-time readings of CO concentrations.
How It Works: The inspector moves the detector around the home, focusing on areas near fuel-burning appliances, heating systems, and attached garages where CO buildup is more likely.
2. Inspecting Fuel-Burning Appliances
Inspectors closely examine appliances like furnaces, gas stoves, and fireplaces for signs of improper combustion, such as soot or yellow flames. They also check for blocked vents or flues that could cause CO to accumulate indoors.
Why It Matters: Poorly maintained or malfunctioning appliances are a common source of carbon monoxide leaks.
3. Testing the HVAC System
Inspectors assess the home’s heating system to ensure it is venting properly. They check for cracks in the heat exchanger or improper installations that could allow CO to leak into living spaces.
Why It Matters: A damaged or aging furnace is one of the most common culprits of carbon monoxide leaks.
4. Checking Ventilation
Proper ventilation is crucial for preventing carbon monoxide buildup. Inspectors evaluate the home’s ventilation system, including chimneys, exhaust fans, and air intakes, to ensure everything is functioning correctly.
Why It Matters: Blockages or inadequate ventilation can trap CO indoors, especially in airtight, energy-efficient homes.
5. Evaluating Carbon Monoxide Alarms
Inspectors verify that carbon monoxide alarms are installed in appropriate locations, such as near bedrooms and on each level of the home. They also check the alarms’ functionality to ensure they are in good working condition.
Why It Matters: A functioning CO alarm can be the first line of defense in alerting occupants to dangerous levels of carbon monoxide.
What Happens If Carbon Monoxide Is Detected?
If elevated levels of carbon monoxide are detected during an inspection, the home inspector will immediately alert the homeowner or buyer. Depending on the severity and source, the inspector may recommend:
- Servicing or replacing faulty appliances.
- Cleaning or repairing blocked vents or chimneys.
- Installing or replacing carbon monoxide alarms.
- Consulting a licensed HVAC technician for further evaluation and repairs.
Carbon Monoxide Testing in Edmonton Homes
Given Edmonton’s cold climate, homes are often sealed tightly during the winter to conserve heat. While this improves energy efficiency, it can also increase the risk of carbon monoxide buildup if ventilation systems or appliances are not functioning properly. Regular inspections are vital to ensure your home is safe.
