Limited Account Access

Account access is running slower  than usual due to heavy traffic. We know it's a pain and we're working to get it back up to speed ASAP. 

In the meantime, payments can still be made from our mobile site on both desktop and mobile devices. Don't hesitate to contact us for emergencies or billing issues.

We apologize for the inconvenience and appreciate your patience. 

If you smell gas anywhere, including in your home, go outside and call 1-800-233-5325 or 911 immediately.

Do not assume that someone else has already reported the emergency. Help us keep your community safe! We consider all of the below a gas emergency:

  • You smell gas or suspect a gas leak
  • There is abnormal pressure (high/low flame) or no gas in all your gas appliances
  • Gas to an appliance or heating unit stays on and cannot be shut off
  • There is a continuous flow of water leaking from your gas heating unit or water heater
  • Gas pipes are making unusual noises like roaring, hissing or whistling
  • You notice dead vegetation that does not have a cause to be there
  • You see a white cloud, mist, fog or bubbles in standing water
  • There is an odor other than natural gas that is irritating to your eyes, nose and/or throat or someone is exhibiting symptoms of carbon monoxide exposure such as headache, nausea, lethargy, disorientation and combativeness

Smell Gas. Act Fast.

As every report of a gas leak is a potentially hazardous situation, we recommend you evacuate the premises and wait for our technician to arrive. Keep this in mind if you suspect a leak:

  • Leave the premise immediately.
  • Leave windows and doors as they are.
  • Do not touch any electrical or light switches, doorbells, phones or anything that could cause a spark such as any appliances or thermostats.
  • Do not turn any electrical equipment on or off.
  • Do not pull plugs from outlets.
  • Extinguish any open flames such as lit candles.
  • If you have a gas range or oven make sure the controls are turned off.
  • Do not smoke or light matches.

Did You Know?

We add a sulfur-smelling chemical called mercaptan to our natural gas to help you recognize a leak immediately. Natural gas is naturally tasteless, colorless, and odorless.
