Common Causes of Carbon Monoxide Leaks in Homes
Cracked heat exchanger (very common)
A cracked heat exchanger allows combustion gases, including CO, to leak directly into the home's air supply. This is the #1 cause of CO emergencies in furnaces. Heat exchangers cannot be repaired—they must be replaced by law and safety standards.
Blocked or disconnected furnace flue
If the exhaust pipe is blocked by animals, snow, debris, corrosion, or collapsed liners, CO backs up into the house. This is extremely dangerous and requires immediate professional attention to clear the blockage and restore proper venting.
Malfunctioning gas boilers
Boilers can produce CO due to poor combustion, failing control boards, low airflow, or burner malfunction. Boiler CO issues require specialized knowledge to diagnose and repair safely.
Improperly vented water heaters
A misaligned or backdrafting water heater flue can release CO into basements and living spaces. Water heater venting issues are common and can be deadly if not addressed immediately.
Gas stoves, dryers, or fireplaces malfunctioning
Any fuel-burning appliance can produce CO when there is insufficient ventilation or equipment failure. All gas appliances must be properly vented and maintained to prevent CO buildup.
Running a car in the garage
Even with the garage door open, CO can drift indoors. Never run a vehicle in an attached garage, even briefly. CO from vehicles can quickly reach dangerous levels inside your home.
Clogged burners or dirty HVAC components
Restricted airflow causes incomplete combustion, producing CO. Regular maintenance prevents this, but neglected systems can develop CO problems that require immediate professional attention.
Recently installed equipment not vented correctly
Poor installation is a top cause of CO exposure. Newly installed heating equipment must be properly vented and tested to ensure safe operation. Improper installation can create immediate CO hazards.
Carbon Monoxide Is One of the Most Dangerous Emergencies a Homeowner Can Face
Carbon monoxide (CO) is one of the most dangerous emergencies a homeowner can face. It's colorless, odorless, and deadly. When a heating system, boiler, furnace, or gas appliance malfunctions, CO levels can rise suddenly—often without any warning until symptoms appear. If your carbon monoxide detector is beeping, or if anyone in the home is feeling dizzy, nauseous, or light-headed, treat this as a life-threatening emergency. We provide 24/7 Carbon Monoxide Emergency Response throughout Nassau County with a 90-minute arrival guarantee, fully equipped to diagnose the source of CO, shut down hazardous equipment, and restore your home's safety. Carbon monoxide is produced when fuel-burning equipment fails to burn gas completely. When HVAC systems or gas appliances malfunction, CO can build up inside your home fast. You cannot see, smell, or taste it. Symptoms are easily mistaken for fatigue or flu. CO poisoning can escalate within minutes. It affects children, pregnant women, and seniors faster. Pets often get sick first—a critical warning sign. Carbon monoxide emergencies require immediate professional intervention to protect your home and your family. For prevention, consider our carbon monoxide detector installation service, and learn more about Home+ Air & Heat and our commitment to your safety.
What We Do During a Carbon Monoxide Emergency
Why Choose Our Carbon Monoxide Emergency Service
Our Simple Process
From call to comfort in 6 easy steps
Immediate Safety Assessment
Upon arrival, we verify occupants are safe, ensure no one is experiencing CO poisoning, shut down unsafe heating equipment, check for backdrafting, and use advanced CO meters to measure indoor CO levels. If CO levels are dangerously high, we coordinate with emergency responders. Your safety comes first.
Locate the Source of the Carbon Monoxide
Using professional-grade equipment, we diagnose furnace heat exchanger condition, boiler combustion system, flue integrity, ventilation blockages, water heater drafting, exhaust leaks, and gas-burning appliance failures. We perform a complete CO pathway inspection to identify the exact source.
Stop the CO at the Source
Depending on the issue, we shut off gas supply, disable unsafe equipment, repair or replace faulty components, clear blocked flue or venting, seal cracks or leaks, replace cracked heat exchangers, or correct ventilation issues. You'll receive photo documentation of the exact source of danger.
Repair or Replace Damaged Components (Same-Day When Possible)
Common emergency repairs include new heat exchanger, flue repair or replacement, combustion chamber repairs, gas valve or burner replacement, venting realignment, draft inducer repair, or boiler combustion tuning. For systems beyond safe repair, we provide temporary heat solutions and next-day installation options.
Full Home Carbon Monoxide Sweep
Before leaving, we retest furnace room, living spaces, bedrooms, basement, and kitchen. CO levels must read 0 ppm before the technician clears the home. We verify your home is safe before completing the service call.
CO Detector Inspection & Replacement
