A propane tank can look simple from the outside, but the service behind it matters most when the temperature drops and your home depends on reliable heat. This first-time propane customer guide explains what to expect before your first delivery, how to make safe choices, and how to avoid the stress of an unexpected runout.
For many Montana homeowners, propane supports more than one appliance. It may heat the house, provide hot water, fuel a range, run a fireplace, or keep a generator ready for an outage. Getting set up properly from the beginning helps protect your comfort all year long.
Start With How You Will Use Propane
Your propane needs determine the right tank size, delivery approach, and pricing option. A home using propane only for cooking will consume far less fuel than a home using it for a furnace, water heater, clothes dryer, and backup generator.
Before arranging service, make a simple list of every propane appliance on the property. Include equipment that may only run occasionally, such as a garage heater, patio heater, generator, or fireplace. If you are buying a home with an existing tank, ask which appliances are connected and request any available past usage records. Those details give your propane provider a better starting point for estimating your needs.
Usage also changes with the property itself. A well-insulated newer home may use less propane than an older home of the same size. Full-time occupancy, thermostat settings, winter travel, rental use, and the elevation and exposure of the property can all affect consumption. A mountain cabin left vacant for weeks requires a different delivery plan than a family home with daily hot-water and heating demand.
Choose a Tank That Fits the Property and the Job
Most residential customers use either an above-ground tank or an underground tank. Above-ground tanks are typically easier to access for inspections, maintenance, and service. They are a practical choice for many homes, especially where the tank can be placed safely while still allowing dependable delivery access.
Underground tanks can be a good option when appearance, lot layout, or neighborhood requirements make an above-ground tank less desirable. They require appropriate site conditions and installation planning, so this option may involve different costs and maintenance considerations.
Tank size is not just about how much propane you want on hand. It is about matching the tank to your expected usage and delivery pattern. A tank that is too small for a propane-heated home can require more frequent deliveries, particularly during a cold Montana winter. A larger tank can offer more reserve and flexibility, but the right choice depends on site access, household demand, and your provider’s delivery system.
Your provider should also evaluate the location before installation. Propane tanks have required clearances from buildings, ignition sources, property features, and other equipment. Delivery trucks need a safe route to reach the tank in every season. A beautiful tank location is not helpful if deep snow, parked vehicles, gates, or a steep driveway prevent a safe winter delivery.
Understand Delivery Options Before You Need Fuel
For a first-time customer, delivery service generally comes down to two approaches: automatic delivery or will-call delivery.
With automatic delivery, your provider estimates when you will need propane based on factors such as historical usage, weather, and the time of year. Many customers prefer this option because it removes the need to watch the gauge every day. A provider using degree-day tracking can adjust delivery timing as temperatures change, which is particularly valuable during long cold spells.
Will-call delivery puts you in charge of monitoring the tank and requesting fuel. It can work well for low-use accounts, seasonal properties, or customers who closely manage their own supply. The trade-off is clear: you must plan ahead. Do not wait until the gauge is nearly empty, especially in winter or before holidays, storms, and busy delivery periods.
Wireless tank monitoring adds another layer of protection. A monitor sends tank-level information to the provider, allowing the delivery team to see usage patterns and schedule fuel proactively. At Big Sky Propane, monitored customers are supported by a Guaranteed No Runouts promise, including a $500 credit if a monitored customer runs out of propane. That kind of accountability matters when propane is keeping your family warm.
Learn the Basics of Your Propane Gauge
Most residential propane tanks have a percentage gauge, not a gallon-by-gallon fuel gauge. The number represents the approximate percentage of the tank’s capacity that remains.
A tank is not normally filled to 100 percent. Propane expands and contracts as temperatures change, so space is left in the tank for safe expansion. A fill level around 80 percent is typical. That means a 500-gallon tank generally holds about 400 gallons when filled to its normal maximum level.
If you are on will-call service, contact your provider well before the tank gets low. Many propane companies recommend calling around 30 percent. Your actual timing may depend on weather, delivery schedules, road conditions, and the amount of propane your home uses each day. During a severe cold snap, a household can use far more fuel than expected.
Never assume a low gauge means you have plenty of time. Propane usage can rise quickly when the furnace runs continuously, guests arrive, or an appliance develops a problem. If you are uncertain about your remaining supply, call and ask. A quick conversation is far better than a cold house and an emergency delivery request.
Make Safe Access Part of Your Routine
Your propane provider handles delivery, but customers play an important role in keeping the tank accessible and the property safe. In Montana, that often means planning for snow and ice long before the first major storm.
Keep the route to the tank clear enough for the driver to reach it safely. Remove vehicles, trailers, stacked firewood, and other obstacles from the delivery path. In winter, clear snow from the tank, regulator, and the route leading to them. Do not bury the tank or regulator under snow, and do not use sharp tools that could damage equipment or piping.
If your tank is behind a locked gate, make sure your delivery arrangement accounts for access. Let your provider know about changes to your driveway, construction work, aggressive animals, or a new code or gate system. These details may seem small, but they can prevent a missed delivery when your tank needs fuel.
Know What to Do If You Smell Gas
Propane has an added odorant so leaks can be detected. If you smell propane, hear a hissing sound near the tank or gas line, or suspect a leak, take it seriously.
Leave the area immediately and keep others away. Do not turn lights, appliances, or electronics on or off. Do not smoke, use a phone near the suspected leak, start a vehicle, or create a spark. If it is safe to do so on your way out, shut off the propane supply at the tank valve. Then call 911 and your propane provider from a safe location.
If you run out of propane, do not simply relight appliances yourself once fuel is delivered. A qualified technician may need to perform a leak check and safely restore service. This protects your home and ensures pilots and appliances are operating correctly.
Ask About Pricing Plans and Billing Options
Propane costs can vary with market conditions and the season, so it helps to understand your payment choices before winter demand arrives. Some customers prefer paying at delivery. Others value monthly budget plans that spread estimated fuel costs over more predictable payments.
Pre-buy or price-protection programs can also be useful for households that want greater control over winter expenses. These options are not one-size-fits-all. A seasonal home with lower and less predictable use may need a different plan than a full-time household with steady heating demand.
Ask how fees, tank rental or installation arrangements, delivery minimums, and service calls are handled. A trustworthy provider will explain the terms clearly and help you choose an approach that fits your household rather than pushing a plan you do not need.
Prepare Before the First Cold Night
Once service is established, save your provider’s phone number where everyone in the household can find it. Teach responsible family members where the tank is located, what propane smells like, and why the tank area should stay clear. If you leave town during winter, keep the thermostat at a safe setting and arrange for someone to check the property after major storms.
Propane service should feel dependable, not complicated. With the right tank, a clear delivery plan, safe access, and a local team that takes responsibility for your supply, you can spend less time watching a gauge and more time enjoying a warm home.
