Carbon monoxide is a colorless, odorless gas that can build up in your Northglenn home without warning. A carbon monoxide testing & safety check before winter ensures your heating system, chimney, and appliances are safe, preventing poisoning and costly repairs.
What Is Carbon Monoxide and Why Does It Threaten Northglenn Homes?
Carbon monoxide (CO) is a deadly gas produced when fuels like wood, gas, or oil burn incompletely. In Northglenn, where winter heating systems run for months, CO can accumulate quickly if your chimney, furnace, or vents are compromised. Unlike natural gas, CO has no smell or color, so it’s impossible to detect without proper equipment. The ((Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that even low levels over time can cause headaches, dizziness, or worse. Homes with older furnaces, blocked flues, or poor ventilation are especially at risk. A carbon monoxide testing & safety check identifies hidden leaks before they become emergencies, giving you peace of mind as temperatures drop.
How Northglenn’s Winter Climate Makes CO Testing Essential
Northglenn’s cold, snowy winters force furnaces, fireplaces, and boilers to work overtime. When chimneys or vents are clogged with creosote or debris, CO can backdraft into living spaces instead of escaping outside. The ((National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that heating equipment is a leading cause of CO incidents in Colorado. Even a small crack in a furnace heat exchanger or a poorly sealed flue can release deadly gas. Scheduling a carbon monoxide testing & safety check in late fall—before the first freeze—lets you catch issues early. Our team at Julian & Gabriel Chimney LLC sees more CO-related calls after heavy snowfall, when chimneys are buried and vents freeze over. Don’t wait for a scare; test now to avoid winter hazards.
Signs Your Northglenn Home May Already Have a CO Problem
If you notice flu-like symptoms that improve when you leave home, it could be CO poisoning. Other red flags include soot around your fireplace, rust on flue pipes, or yellow flames in your gas appliances. In Northglenn, homes near the ((Thornton, CO|/areas/thornton-co/) or Federal Heights, CO areas often face older housing stock with outdated chimneys, increasing CO risks. Even newer homes can have issues if vents are improperly installed. A carbon monoxide testing & safety check catches these problems early. If you’re unsure, our experts recommend installing a CO detector near bedrooms as a backup. Symptoms like nausea or confusion warrant immediate evacuation and a professional inspection.
What Happens During a Professional Carbon Monoxide Testing & Safety Check in Northglenn?
A licensed chimney sweep from Julian & Gabriel Chimney LLC starts with a visual inspection of your chimney, flue, and vents for cracks, blockages, or corrosion. We then use specialized CO meters to measure gas levels in your home, focusing on areas near heating appliances. If we detect elevated CO, we’ll identify the source—whether it’s a cracked heat exchanger, a blocked chimney, or a faulty vent. Our team also checks your CO detectors to ensure they’re functional and properly placed. For Northglenn homes with wood-burning fireplaces, we’ll assess creosote buildup, which can restrict airflow and force CO back into your home. The entire process takes about an hour, and we provide a detailed report with recommendations. Schedule yours today before winter demand peaks.
How Often Should Northglenn Homeowners Schedule CO Testing?
The CSIA recommends testing CO levels annually, but Northglenn homeowners should consider more frequent checks if they have older systems, use wood heat, or live in drafty homes. After heavy snowfall or high winds, schedule a quick inspection—especially if your chimney is exposed on a north-facing roof. Homes in the Brighton, CO or Wheat Ridge, CO areas with older masonry chimneys may need bi-annual checks due to freeze-thaw damage. If you’ve recently upgraded your furnace or installed a new fireplace, test within 30 days to ensure proper ventilation. Our pricing starts at $99 for a basic CO safety check, with full inspections available for $199. View our full pricing guide for details.
DIY vs. Professional CO Testing: What Northglenn Homeowners Should Know
While $20 CO detectors are essential, they’re not enough to guarantee safety. DIY tests only alert you to existing gas—not the root cause. In Northglenn, where chimneys and vents are often hidden behind insulation or snow, a professional can spot issues like cracked flues or improperly sized vents that a detector misses. The EPA's Burn Wise program advises homeowners to pair detectors with annual professional testing. Our team uses calibrated equipment to detect even trace amounts of CO, ensuring no hazard goes unnoticed. For just $49, we’ll install a high-quality detector during your visit.

Frequently Asked Questions
Should I get a carbon monoxide testing & safety check in Northglenn even if my furnace is new?
Yes. New furnaces can still leak CO if vents are improperly installed or if the heat exchanger cracks. The CSIA recommends testing annually, regardless of system age. Schedule a check before your first winter use to confirm safety.
Is it worth the cost to upgrade my Northglenn home’s chimney before winter if CO levels are high?
Absolutely. Upgrading a cracked flue or installing a new liner can cost $1,500–$3,500, but it’s far cheaper than medical bills or a CO-related tragedy. Compare repair vs. replacement costs to make an informed decision.
Do I really need a professional carbon monoxide test if my Northglenn CO detector hasn’t gone off?
Detectors only alert you to existing gas—they don’t fix the problem. A professional test identifies hidden leaks, improper venting, or appliance issues before they become emergencies. Don’t rely solely on alarms; test proactively.
