24/7 Emergency Service

Safety-related HVAC issues: what to do and when to call.

Some HVAC situations require immediate action before calling anyone. Others need professional diagnosis. Here is the breakdown.

Act Immediately: Before Calling Anyone

Gas smell: Exit home immediately. Do not touch switches. Call National Grid 1-800-892-2345 or NYSEG 1-800-572-1111 from outside.
CO detector alarm: Evacuate immediately, including pets. Call 911. Do not re-enter until emergency services clear the home.
Burning smell from electrical: Shut off the system at the thermostat or disconnect, exit if the smell is strong or smoke is visible.

Call AmeriHeat for Diagnosis

Furnace causing roll-out switch trips or frequent safety shutdowns
CO detector triggered but no active emergency: need source identified
Combustion analysis needed after gas utility clears a smell
Concerns about cracked heat exchanger (older furnace, unexplained symptoms)
Venting or draft issues on furnace or water heater
Burning smell after gas utility has confirmed no supply leak

Safety-related HVAC issues in Rochester NY: what we find and what it means.

AmeriHeat diagnoses and repairs safety-related HVAC issues across Rochester NY and the surrounding Monroe, Wayne, and Ontario County area. The real service call photos on this page are not stock illustrations. They are actual safety issues we have found on Rochester area service calls. This page explains what those issues are, why they matter, and what to do if you think you have one.

Cracked heat exchanger: the most serious residential HVAC safety issue

The hero photo on this page is a real AmeriHeat service call in Rochester: a cracked heat exchanger found via combustion analysis and visually confirmed, with roll-out switches tripping during operation. The roll-out switches are a safety feature: they shut the furnace down when flames roll out of the heat exchanger rather than staying contained in the combustion chamber. Roll-out switch trips are a safety signal that something is seriously wrong with the heat exchanger.

A cracked heat exchanger allows combustion gases, including carbon monoxide, to mix with the circulated air that the furnace blows through your home. CO is colorless and odorless. Without a functioning CO detector, a cracked heat exchanger can cause CO accumulation in a sealed Rochester home without any visible warning sign. The Macedon service call in our recent jobs section is the same failure from a different angle: plugged secondary heat exchanger producing extremely high CO output, caught during a routine service call before it became a health incident.

If your furnace is exhibiting roll-out switch trips, repeated safety shutdowns, unusual combustion smells, or you have an older furnace (15+ years) and a CO detector that has alarmed, call 585 454 8422. We run combustion analysis and visually inspect the heat exchanger. A confirmed cracked heat exchanger typically means the furnace needs replacement. We give you that assessment in writing before any decision.

Gas smell: what to do and who to call first

If you smell natural gas near your furnace or water heater, the correct sequence is: (1) do not touch any electrical switches or use your phone inside; (2) exit the home immediately and leave the door open; (3) call National Grid at 1-800-892-2345 or NYSEG at 1-800-572-1111 from outside; (4) wait for the utility to respond and clear the home before re-entering. Gas supply leaks are the utility's responsibility to locate and repair. After the utility has confirmed no active supply leak and the home is safe, call AmeriHeat to assess whether the smell is coming from equipment-side connections (gas valve, burner assembly, or fittings on the furnace or water heater) that we can inspect and repair.

CO detector alarm and carbon monoxide from HVAC equipment

If your CO detector alarms: evacuate immediately, including pets. Call 911. Do not re-enter until fire or emergency services clear the space. Carbon monoxide from HVAC equipment is produced when combustion gases are not properly exhausted. The most common HVAC sources in Rochester homes: cracked or plugged heat exchanger (confirmed in multiple Drive photos), blocked or improperly installed flue venting, and draft problems on water heaters or boilers sharing a venting system with the furnace. The Macedon venting issue in our process section is a real example: a water heater not drafting properly, found during a furnace cleaning visit. Shared venting problems are common in Rochester's older homes where multiple combustion appliances were added over decades.

Rochester's sealed winters amplify CO risk significantly compared to milder climates. When homes run with windows closed for six or more months, CO that leaks from a heat exchanger or poorly vented appliance accumulates in the living space more rapidly than it would in a home with regular fresh air dilution. A small heat exchanger crack that might cause only mild symptoms in a leakier home can cause serious CO exposure in a well-sealed Rochester home during a cold winter. This is why Rochester homeowners with older furnaces and aging housing stock benefit more from annual combustion testing than homeowners in warmer climates. Annual combustion testing is the primary prevention tool. We measure CO output, stack temperature, and combustion efficiency at every annual furnace service visit.

Safety-related HVAC concern in Rochester NY? AmeriHeat provides combustion analysis, heat exchanger inspection, and venting assessment across Monroe, Wayne, and Ontario Counties. Call 585 454 8422. Justin or Colby answers the phone. For active gas leaks or CO alarms: exit first, call your gas utility or 911 first.

Annual combustion testing: the most important HVAC safety practice

A combustion analysis measures CO output, stack temperature, and combustion efficiency on gas and oil-fired equipment. It is how we find safety issues before they become emergencies. The Macedon plugged heat exchanger in our recent jobs section was caught on a service call: combustion testing showed extremely high CO output from a furnace that appeared to be working normally. The Rochester cracked heat exchanger was found on a no-heat call where roll-out switches were tripping. Both were safety problems that had been developing for some time before they were caught. Annual service gives us the opportunity to catch these issues on your schedule rather than after a CO detector alarms at 2 AM. See our maintenance plans page for annual service options.

HVAC safety FAQ.

Direct answers to what Rochester homeowners ask about HVAC safety issues.

What should I do if my CO detector goes off?+

Evacuate immediately, including pets. Do not stop to investigate. Call 911 from outside the home. Do not re-enter until the fire department or emergency services clear the space. Once the home has been confirmed safe, call AmeriHeat at 585 454 8422 to diagnose the HVAC source. Common HVAC sources of CO in Rochester homes include cracked or plugged heat exchangers and draft/venting problems on furnaces or water heaters.

What should I do if I smell gas near my furnace?+

Do not touch any electrical switches, light switches, or appliances. Do not use your phone inside. Exit the home immediately and leave the door open. Call National Grid at 1-800-892-2345 or NYSEG at 1-800-572-1111 from outside the home. Wait for the gas utility to respond and confirm the home is safe before re-entering. After the utility clears the home, call AmeriHeat to assess whether the smell is coming from equipment-side connections on your furnace or water heater.

What is a cracked heat exchanger and why is it dangerous?+

The heat exchanger is a metal component in your furnace that separates the combustion chamber from the air that circulates through your home. A crack in the heat exchanger allows combustion gases, including carbon monoxide, to mix with the air blown through your living space. CO is colorless and odorless. A cracked heat exchanger can cause CO accumulation in a sealed Rochester home without any visible sign. It is diagnosed via combustion analysis and visual inspection. A confirmed cracked heat exchanger typically means the furnace needs replacement.

How does AmeriHeat check for heat exchanger problems?+

We run a combustion analysis that measures CO output, stack temperature, and combustion efficiency. Elevated CO output or an abnormal combustion profile prompts a visual inspection of the heat exchanger. We also look for evidence of roll-out switch trips, unusual combustion smells, or burner flame patterns that indicate a heat exchanger problem. Annual combustion testing is how we catch cracked or plugged heat exchangers before they cause a CO incident. We include this testing in our annual maintenance plans.

Can a furnace safety shutdown be a CO warning sign?+

Yes, in some cases. A furnace repeatedly shutting off on a high limit or with roll-out switches tripping is a safety signal that warrants investigation. When a furnace shuts off on a roll-out switch, do not reset it repeatedly. Call 585 454 8422 for a diagnosis. Our service calls have found furnaces shutting off on safety limits because the heat exchanger was producing dangerous CO levels.
