Intermountain Gas Company bill payment methods and where to send payments
Intermountain Gas Company, which serves customers in Idaho and eastern Oregon, offers several ways to pay your bill: online through their website, by phone, by mail, or in person at authorized payment locations. The fastest route is online at intermountaingas.com, where you can set up a one-time payment or enroll in automatic monthly payments. If you prefer to call, their customer service line accepts payments by phone, though you may encounter wait times during peak hours.
Mailing a check or money order takes longer — typically 7 to 10 business days to reach their processing center and post to your account. If you mail a payment close to your due date, it may arrive after the deadline, which can trigger a late fee. The company's mailing address appears on your bill statement; use that specific address rather than searching for a general corporate office address, because payments sent to the wrong location will be delayed.
Some customers pay in person at local authorized retailers or payment centers in their service area. These locations vary by region, so check the Intermountain Gas website or call their customer service line to find one near you. In-person payments typically post to your account within one business day.
Key Takeaways
- Online payment through intermountaingas.com is the fastest method and allows you to pay immediately without waiting for mail delivery or phone lines.
- Automatic monthly payments can be set up online or by phone and remove the risk of missing a due date, though you should monitor your account to catch billing errors.
- Mailed payments take 7 to 10 business days to post, so sending a check near your due date risks a late fee if it arrives after the deadline.
- Late payments incur a fee and may result in service disconnection if the account falls significantly behind, so paying by the due date shown on your bill matters.
Setting up automatic payments to avoid missed due dates
Automatic payments, also called autopay, withdraw money from your bank account or charge your credit or debit card on a set day each month. You can enroll through the Intermountain Gas website by logging into your account, selecting the autopay option, and providing your banking or card information. The company will ask you to choose a payment date — typically between the 1st and the 28th of the month — and the amount to pay (usually your current bill balance).
Autopay removes the burden of remembering to pay each month, but it does not protect you from billing errors. You should still review your bill each month to catch mistakes, unusual charges, or rate changes. If you spot an error, contact customer service before the autopay date to dispute it or adjust the payment amount. If you cancel autopay, you return to manual payment, so mark your calendar or set a phone reminder for the due date.
What happens if you miss a payment or pay late
A payment is considered late if it does not reach Intermountain Gas by the due date printed on your bill. Late payments trigger a late fee, which is added to your next bill. The amount of the late fee varies by state and is shown in your service agreement or on the company's website; contact customer service if you need the exact amount for your account.
If your account remains unpaid for a longer period — typically 30 to 60 days past due, depending on your state — the company may issue a disconnection notice. This notice gives you a window (usually 10 to 15 days) to pay the full amount owed or arrange a payment plan before service is shut off. Once service is disconnected, you must pay the full balance plus a reconnection fee to restore gas service.
If you cannot pay your full bill by the due date, contact Intermountain Gas customer service immediately. Some customers are offered payment arrangements or budget billing plans, which spread your bill over several months or average your payments across the year. These options are not may provide, but asking before you fall behind gives you the best chance of working out a solution.
Understanding your bill and what you are paying for
Your Intermountain Gas bill includes the cost of the natural gas you used during the billing period, plus several other charges. The commodity charge is the price per unit of gas consumed; this fluctuates with market prices and is the largest variable part of your bill. The delivery charge covers the cost of maintaining pipes, meters, and customer service; this is usually fixed or changes only once or twice per year.
You may also see taxes, regulatory fees, and seasonal adjustments on your bill. Some of these are set by state law or local ordinance and are not negotiable. If a charge appears unfamiliar or unusually high, your bill statement should explain it; if not, customer service can walk you through each line item.
Your bill also shows your usage in therms (a unit of heat energy) and may include a comparison to your usage in the same month last year. If your usage spikes unexpectedly, it may signal a leak or a meter problem. Contact customer service to report a suspected leak or request a meter check.
Disputing a charge or reporting a billing error
If you believe your bill contains an error — a charge you do not recognize, usage that seems too high, or a duplicate charge — contact Intermountain Gas customer service and explain the problem. You do not need to pay the disputed amount while the company investigates, though you should pay any undisputed charges to avoid a late fee on the rest of your account.
The company will review your meter reading, your usage history, and your account for errors. This process typically takes 30 to 45 days. If the company finds an error in your favor, they will issue a credit to your account; if they find no error, they will explain their findings and you can choose to pay the bill or request further review. Keep records of all correspondence about the dispute in case you need to reference it later.
Payment options if you have trouble affording your bill
If your gas bill is difficult to afford, several options may be available. Budget billing averages your annual gas costs and spreads them evenly across 12 months, so your bill is more predictable and usually lower in winter months when usage peaks. You can ask about budget billing when you call to make a payment or log into your online account.
Some states and local utilities offer low-income assistance programs that help pay heating bills for households that meet income limits. These programs are often run by community action agencies or local government offices, not by Intermountain Gas itself. Your state's energy office or a 211 referral service can tell you whether such a program exists in your area and how to reach it.
If you are facing disconnection, contact customer service immediately and ask about a payment plan or deferred payment agreement. These arrangements allow you to pay part of your bill now and the rest over several months, though interest or fees may apply. The sooner you contact the company, the more options you may have.
Frequently Asked Questions
Can I pay my Intermountain Gas bill with a credit card online?
Yes, you can pay with a credit or debit card through the Intermountain Gas website. Be aware that the company may charge a convenience fee for credit card payments, typically 2 to 3 percent of the payment amount. Check the payment screen for the fee before you confirm the transaction. Paying by bank account transfer (ACH) usually has no fee.
What should I do if my payment was not posted to my account?
If you paid online or by phone and the payment has not appeared within one business day, log into your account or call customer service with your confirmation number. If you mailed a check, wait at least 10 business days before contacting the company. Have your bill statement and payment details ready when you call.
Can I set up autopay to pay only part of my bill each month?
Most autopay systems allow you to choose the payment amount, so you can set it to less than the full bill if you prefer. However, paying less than the full amount will leave a balance that accrues interest or late fees. It is usually better to pay the full bill or contact customer service about a formal payment plan.
What happens if I move and still owe a balance on my Intermountain Gas account?
Contact customer service to close your account and arrange final payment before you move. If you leave an unpaid balance, the company may pursue collection action or report the debt to credit agencies. Settling the balance before you leave is simpler than dealing with collection calls later.
Does Intermountain Gas offer paperless billing?
Yes, you can enroll in paperless billing through your online account. This means you will receive an email notification when your bill is ready to view, rather than receiving a paper statement by mail. Paperless billing does not change your payment options or due date — it only changes how you receive the bill.
