Suspect a gas leak? Leave the area immediately. From a safe location, call 911 and Southwest Gas at 1-877-860-6020. Follow the utility’s emergency instructions; do not wait for an email response.
Contact Southwest Gas Customer Solutions
The posted Customer Solutions hours are Monday–Friday, 7 a.m.–6 p.m. PST, excluding holidays. Relay users can dial 711. The contact page links to online account service and an email form for nonemergency questions. The office-hours listing is for routine assistance, not a reason to delay reporting a suspected leak.
Billing, Payments and Account Questions
Start with MyAccount for your account information, or open Contact Us for payment and assistance links. When asking about an unexpected bill, have the service address, billing period, disputed amount and payment confirmation available. Explain whether you are querying usage, a fee, a missing payment or the total balance; these are different problems.
For a payment difficulty, ask which arrangements or assistance programs apply to your account and what deadline still applies while the request is reviewed. Record any agreement and confirmation number. A request for help is not itself confirmation that a payment date has changed.
Start, Stop or Transfer Gas Service
Use the Start, Stop or Move Service option linked from Southwest Gas’s contact page. Prepare your current and new service addresses, requested dates and a reliable contact number. Ask whether access or an appointment is needed and keep the confirmation for each address. Do not assume service transfers automatically because your mailing address changed.
Outages and Urgent Concerns
Southwest Gas links its outage information through the account portal. An outage update and an individual service appointment answer different questions; contact Customer Solutions if you need to clarify which applies to your address. If the situation includes a suspected leak, use the emergency instructions above immediately.
Following Up on an Unresolved Request
Keep a short timeline with contact dates, case numbers and what was promised. On a follow-up, ask for the current case owner, any missing information and the next expected step. For a billing dispute, identify the specific charge and the resolution you are requesting. Send supporting records only through the utility’s official channels.
