Gas Leak Signs & Symptoms
Smells & Sounds
Rotten Egg or Sulfur Smell
A strong sulfur smell in your home is the clearest indicator that natural gas is escaping somewhere in the system.
Hissing Near Gas Lines
A hissing or whistling noise around gas lines, fittings, or the gas meter often means gas is leaking under pressure.
Gas Odor Around Appliances
If the smell is strongest near your furnace, stove, water heater, or fireplace, the leak may be coming from a connection or valve.
Appliance Warning Signs
Unstable or Red Pilot Light
A flickering, weak, or red pilot light on your household appliances can signal poor combustion or a nearby gas leak.
Unexpected Gas Bill Increase
A sudden spike in your gas bill without increased use can point to a hidden leak in your home’s gas lines.
Dead Plants Above Lines
Discoloured or dying plants above buried gas pipelines may indicate gas escaping underground. If you notice any of these signs, call Real Deal HVAC immediately.
Visual Signs
Dust or Air Movement Around Gas Lines
A dust cloud, blowing soil, or unusual air movement near a gas line can point to a break or loose fitting.
Bubbling or Disturbed Ground
Outdoor leaks can cause bubbling water, shifts in soil, or small disturbances around underground gas lines.
Gas Smell Near the Meter
If the odor is strongest around the gas meter or shutoff valve, the leak may be coming from the supply line.
What To Do If You Suspect
A Gas Leak
If you suspect a gas leak inside your home, it’s important to act quickly and follow proper safety steps. Start by evacuating the house and moving everyone a safe distance away, avoiding the use of light switches, cell phones, or anything that could create a spark. Stay clear of open flames, avoid smoking, and do not start your car. If it can be done safely, shut off the gas shutoff valve before calling your utility company or the gas company emergency number to report the issue. If you cannot leave safely, contact the fire department for assistance. Once authorities confirm it is safe to re-enter, Real Deal HVAC can provide a full inspection and complete repair to restore your home’s natural gas safety. To help prevent emergencies, keep smoke alarms, carbon monoxide detectors, and smoke detectors in working order on every level of your home, keep a fire extinguisher accessible, and consider installing a dedicated gas leak detector for added protection.
What Causes Gas Leaks
Across Toronto Homes
Many gas leaks begin with conditions that develop slowly over time, especially in older homes where the natural gas system has been exposed to years of wear. As gas pipelines age, corrosion, rust, and weakened fossil-fuel piping materials can create tiny openings that allow natural gas to escape without being immediately noticeable. Valves and seals also deteriorate with use, and even a small amount of wear can lead to inconsistent pressure or a gradual leak.
Loose or poorly fitted connections on furnaces, stoves, water heaters, fireplaces, and other household appliances are another common source of leaks. These appliances run frequently throughout the year, and small shifts, vibration, or temperature changes can cause fittings to loosen. In many cases, the leak remains hidden until the sulfur smell becomes strong or a hissing sound is heard near the appliance.
Environmental factors play a large role as well. Extreme weather, rapid temperature swings, or shifting ground pressure can stress outdoor gas lines and fittings, increasing the chance of cracks or weakened joints. Poor ventilation inside the home may also contribute to carbon dioxide buildup and create unsafe conditions around natural gas appliances.
During our inspection, we look beyond the leak itself. Our team identifies the exact point of failure and determines what caused it, whether it was aging components, appliance issues, or environmental stress. This approach ensures your home stays safe long-term and reduces the chance of the problem returning.
Common Gas Leak Causes
Aging or Damaged Gas Lines
Older or corroded gas pipelines, worn fossil-fuel piping materials, and damaged valves can let natural gas escape into your home over time.
Loose or Faulty Appliance Connections
Household appliances such as furnaces, stoves, water heaters, and fireplaces can develop loose fittings or malfunctioning parts that lead to slow, hidden leaks.
Pressure or Ventilation Problems
Extreme weather, shifting ground pressure, and poor ventilation can cause carbon dioxide buildup and stress your natural gas system, increasing the risk of leaks.
