How do I know if I have a gas leak?

Gas leaks are extremely hazardous. Signs of a gas leak can include:

  • Hissing or whistling sounds near gas lines or appliances
  • Blowing dirt or bubbles in standing water
  • Dead or discolored vegetation near gas lines
  • Physical symptoms like dizziness, nausea, or headaches
If you suspect a gas leak, immediately evacuate the area and call your gas company or 911 from a safe location. Avoid any open flames or sparks.

What is carbon monoxide, and how can it affect my HVAC system?

Carbon monoxide (CO) is an invisible and odorless that is dangerous when inhaled. Malfunctioning fuel-burning appliances, like furnaces or boilers, can produce carbon monoxide. A cracked heat exchanger in a furnace is a common source of carbon monoxide leaks in homes. Regular HVAC maintenance, including inspection of the heat exchanger, is important for preventing carbon monoxide leaks. CO detectors save lives.
