Residential vs. commercial propane delivery: what's actually different

We hear it most often from a rancher outside Mountainair or a shop owner off the interstate near Moriarty: "We were on the same delivery plan as my house, and it just didn't keep up." That's usually the whole problem in one sentence. Residential and commercial propane accounts look alike on an invoice, but they consume fuel on completely different clocks — and running a business on a residential schedule is how a job site or a barn ends up empty at the worst possible time.

Here's what actually separates the two, and how our team decides which one you belong on.

Tank size is set by peak load, not square footage

Most homes across our service area — Mountainair, Pecos, Moriarty, and roughly 35 miles around each — run a tank in the 250-to-500-gallon range when propane handles heat, hot water, cooking, and a dryer. Homes using propane only for a range or a fireplace get by with less. Those sizes are built around a heating season in the high desert, where nights drop hard even after a warm day.

Commercial sites blow past that quickly. A welding or fabrication shop, a restaurant kitchen, a greenhouse, a livestock or poultry barn, a construction trailer running temporary heat — these draw at rates that would empty a home-sized tank in days. That's why commercial locations commonly run 1,000-gallon tanks, sometimes several manifolded together.

And size isn't only about how often we come out. In cold weather, a tank has to vaporize liquid propane fast enough to feed your burners. Undersized storage can starve equipment on a cold morning at elevation even when the gauge still shows fuel. At the altitudes we serve in central New Mexico, appliance derating and vaporization capacity are worth taking seriously — that's a sizing conversation, not a guess.

Delivery cadence: the thermostat vs. the work order

Residential usage is predictable. Colder weather means more furnace hours, and consumption follows in a curve our team can forecast from a household's own history. That's what makes automatic delivery genuinely reliable for homes — we can plan the fill before anyone thinks about the gauge.

Commercial usage doesn't follow the weather. It follows the work. A shop that picks up a big contract triples its burn for six weeks. A greenhouse hits its heaviest demand in a specific stretch of spring. A crew running temporary heat on a build consumes on the general contractor's calendar, not ours.

So commercial accounts need a different rhythm: an agreed reorder point, usage monitoring, and a live line to dispatch instead of a weather formula. Some of our commercial customers call when a job is booked. Others are on a fixed interval regardless of the gauge. What doesn't work is quietly inheriting a residential autofill pattern and hoping it stretches.

Agricultural and irrigation propane is its own category

New Mexico ag runs on propane in ways most homeowners never encounter: irrigation pump engines, livestock and poultry barn heat, greenhouse and nursery heat, weed and pest flaming, crop drying, and standby generators at remote wells. These loads are seasonal, heavy, and unforgiving about timing — an irrigation engine that quits mid-set costs water, labor, and sometimes a crop.

Remote ag sites also come with delivery realities our drivers need to know up front. Long unpaved access roads, arroyo crossings that wash out after monsoon storms, cattle guards and gates, and tank locations set well back from anywhere a bobtail can turn around. In a wet August those roads change fast; in a dry winter they're fine. Telling us about site access before the first fill saves everyone a wasted trip.

If you farm or ranch, give us your calendar. Knowing your irrigation season or your barn schedule lets us stage volume ahead of demand instead of chasing it across the county.

Billing structure and why route separation matters

Home accounts and business accounts are usually built differently. Households commonly use even-payment or budget plans, prebuy or price-protection arrangements, and simple per-delivery invoicing. Commercial accounts more often involve volume-based terms, contract pricing tied to a market index, net payment terms, purchase orders, and separate invoicing by site for operations with more than one location.

Route economics matter to you as much as to us. A residential route is built on density — many stops in a stretch of town, each taking a modest drop. One commercial stop can take most of a truck. Slide that stop into a residential route and either the business waits or the neighborhood behind it does. Across the distances we cover between Pecos, Moriarty, and Mountainair, that difference is measured in hours, not minutes. Separating the routes is how both groups get served properly.

A quick self-check — you likely belong on a commercial schedule if:

• Your usage tracks production, jobs, or irrigation, not the thermostat
• You store 1,000 gallons or more, or run multiple tanks
• A runout costs you money, spoilage, or downtime — not just comfort
• You need PO numbers, net terms, or per-site invoicing
• Your site needs a coordinated delivery window or a specific contact on the ground

Getting set up the right way

Most of this comes down to one honest conversation about what you burn and when. Our team can pull your usage history, look at the site, check tank sizing against your real peak load, and put you on a schedule and billing setup that fits — a simple autofill for the house, or a monitored commercial account with terms.

If you run a shop, farm, ranch, greenhouse, or job site anywhere within about 35 miles of Mountainair, Pecos, or Moriarty and you're not sure your setup holds up, call us at (505) 407-2260 or visit https://southwestpropane.org. Tell us what you run and how hard you run it, and we'll give you a straight answer about whether your current arrangement will carry you through the next season.
