Carbon Monoxide: What Every Homeowner Must Know
Carbon monoxide is a colorless, odorless, tasteless gas produced by the incomplete combustion of fossil fuels. Any appliance that burns natural gas, propane, oil, or wood — including furnaces, water heaters, gas stoves, and fireplaces — is a potential source of CO in your home.
When inhaled, CO binds to hemoglobin approximately 200 times more readily than oxygen, effectively starving tissues and organs. At low concentrations, symptoms mimic the flu. At high concentrations, CO can cause unconsciousness and death within minutes. Consumer CO detectors do not detect gradual buildup at the low levels that cause chronic symptoms.
Professional testing your consumer detector cannot match.
Our technicians use calibrated professional CO detection equipment to measure ambient levels in every occupied room and near every combustion appliance. We inspect heat exchangers, venting, and flue connections — the most common sources of residential CO leaks — and document all findings in a detailed report.
If elevated CO or appliance deficiencies are found, we provide specific remediation options with clear written pricing before any repair work begins.
Certified Safety Inspection
Every Combustion Appliance Checked
Our CO inspection covers every combustion appliance in your home — furnace, water heater, boiler, gas range, and fireplace. We test combustion quality, check heat exchanger integrity, and verify detector placement.
Warning Signs of Potential CO Exposure
Persistent Headaches at Home
Headaches, dizziness, or fatigue that consistently improve when you leave the house are a classic early indicator of low-level CO exposure.
Multiple People Symptomatic
When multiple family members experience flu-like symptoms simultaneously — especially without fever — CO exposure should be ruled out immediately.
Appliance Warning Signs
A yellow or orange furnace flame instead of blue, soot around gas appliances, pilot lights that frequently extinguish, or excessive condensation near appliances all indicate combustion problems.
Older Appliances and Systems
Furnaces and water heaters over 10 years old are at higher risk for cracked heat exchangers and deteriorating flue connections — the primary causes of appliance-related CO leaks.
Our Professional CO Testing Process
Initial Assessment
Our technician surveys all fuel-burning appliances, venting systems, and potential CO sources throughout your home using calibrated detection equipment.
Ambient Air Testing
We measure CO levels in every occupied room and utility area to establish a comprehensive baseline of exposure throughout the home.
Appliance Inspection
Each gas furnace, water heater, stove, and combustion appliance is inspected for proper venting, complete combustion, and heat exchanger integrity.
Report and Recommendations
You receive a detailed report of all readings and any identified risks, along with specific recommendations for remediation, detector placement, and ongoing monitoring.
Protecting Your Family
CO Safety and Indoor Air Quality Together
Carbon monoxide testing is the first step in comprehensive indoor air safety. We combine CO inspection with an IAQ assessment so you get a complete picture of your home air health in a single visit.
What Our Customers Say
“We had been having headaches for weeks and couldn't figure out why. Weatherford found a cracked heat exchanger in our furnace leaking CO. They fixed it the same day.”
“I wanted CO testing as part of our annual furnace inspection. They used professional-grade equipment, not just a consumer detector, and gave us a written report. Very thorough.”
“Our CO alarm kept triggering at low levels and no one could explain it. Weatherford traced it to an improperly vented water heater. Fixed and safe the same visit.”
Frequently Asked Questions
How is professional CO testing different from a consumer CO detector?
Consumer CO detectors are calibrated to alert at 70 PPM or higher to reduce nuisance alarms. Professional instruments can detect and measure CO at 1 PPM or below, allowing technicians to identify chronic low-level exposure and trace it to a specific appliance or venting fault before it reaches alarm levels.
When should I get professional CO testing?
Any time family members experience unexplained headaches, nausea, or flu-like symptoms that resolve when they leave the home. Also before winter heating season, when a furnace is installed or repaired, when a new fuel-burning appliance is added, or after any flooding that could have affected appliance venting.
What happens if you find elevated CO levels in my home?
If we find dangerous levels, we identify the source immediately and provide a written repair estimate on the spot. For any situation that poses an immediate risk, we will advise you to vacate until the source is corrected. All repair work requires your written authorization before we begin.
