24/7 Carbon Monoxide Emergency Service on Long Island

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.

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.

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.

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.

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.

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.

Restricted airflow causes incomplete combustion, producing CO. Regular maintenance prevents this, but neglected systems can develop CO problems that require immediate professional attention.

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.

Is it safe to stay indoors if the detector only beeps once?

No. Treat every CO alert seriously. Leave the home immediately and call us. Even a single beep can indicate dangerous CO levels. Carbon monoxide has no odor, so you cannot detect it without a detector. Don't take chances with CO.

Can you repair a cracked heat exchanger?

No. By law and safety standards, a cracked heat exchanger must be replaced. Repairs are not safe or legal. Heat exchangers are critical safety components—when they crack, they allow combustion gases including CO to leak into your home's air supply.

Can opening windows fix CO problems?

Opening windows may temporarily reduce symptoms, but the leak will continue. Professional repair is required to stop the source of CO. Ventilation alone cannot solve a CO problem—you must fix the equipment malfunction causing it.

Why didn't I smell anything?

Carbon monoxide has no odor—that's what makes it so dangerous. You cannot see, smell, or taste CO. This is why CO detectors are essential. Without a detector, you may not know CO is present until symptoms appear, which can be too late.

Should I call 911 or you first?

If anyone has symptoms (headache, dizziness, nausea, confusion): call 911 first, then us. If no symptoms but detector is sounding: call us immediately. In all cases, evacuate the home immediately and wait outside until help arrives.

What are the warning signs of a CO problem?

Physical symptoms include headache, confusion, dizziness, nausea, chest tightness, shortness of breath, blurred vision, or fainting. Home symptoms include CO detector beeping, furnace shutting off repeatedly, soot or scorch marks around equipment, condensation on windows, yellow or flickering flames, strange furnace smells, pets acting weak, or backdrafting from flue systems.

What causes carbon monoxide leaks in homes?
