Safety guide

Stay safe with propane

Propane has an added odorant (ethyl mercaptan) — it smells like rotten eggs or a skunk. Listen for hissing near appliances or the tank. Look for dead or discolored vegetation near buried lines. Frost on the outside of your tank can also indicate a problem.

Put out all flames immediately. Do NOT touch any electrical switches. Leave the building and leave the door open. Turn off the main valve on your tank if safe to do so. Call us and 911 from outside or a neighbor’s phone. Do not re-enter until cleared by emergency responders.

Never let your tank drop below 20% in winter. Keep snow and ice clear from tank vents, regulators, and lines. Do not use a heat gun or open flame to thaw frozen regulators — call us instead. Note: propane contracts in extreme cold, so your gauge may read lower than expected.

When a tank empties fully, air and moisture enter the lines. All appliances must be inspected and re-lit by a certified technician before use — this is a safety code requirement, not optional. Call us immediately at (320) 555-0197. We’ll deliver and send a technician for the re-light.

Have all propane appliances inspected by a licensed technician every year. Check that burner flames are steady blue — not orange or yellow. Install carbon monoxide detectors on every level of your home. Never attempt DIY repairs on gas lines or appliances.

Pricing programs

Manage your propane costs

Propane prices fluctuate seasonally — rising in fall as winter demand builds. We offer programs to protect your budget.

Limited time

Pre-buy propane & lock in this season’s price before winter

Pricing varies by volume, delivery location, and program. Call us for a current quote — we’ll find the program that fits your needs and budget.

Frequently asked questions

Call when your tank gauge hits 20–30%. In winter, deliveries can take 2–3 business days, so don’t wait until it’s below 10%. Automatic delivery customers don’t need to monitor this — we handle it.

It depends on your original installation. Leased tanks are tied to a specific supplier. Owned tanks can be filled by any provider, including us. Check your installation paperwork, or call us at (320) 555-0197 — we’ll help you find out.

Yes, if you own your tank outright. We cannot fill tanks leased from another provider as those remain their property. Call ahead to confirm before scheduling your first delivery with us.

Residential deliveries typically have a 100-gallon minimum. For smaller tanks or unusual situations, call us — especially for first-time customers or emergency fills where we’ll do our best to accommodate you.

We use your usage history and weather data to estimate when you’ll need propane and schedule delivery proactively. You’ll receive a notification before we arrive. No calls or monitoring required on your end.

Residential tanks from 100 to 1,000 gallons, agricultural bulk tanks, and commercial tanks of various sizes. We also sell portable 20 lb, 33 lb, and 100 lb cylinders at our C-store location.
