# What to Expect During a New Propane Tank Installation

If you're setting up propane for the first time at your home or small business in Pecos, Mountainair, Moriarty, or anywhere in our 35-mile service radius, a tank installation involves more than just dropping a tank in your yard. There's permitting, site prep, delivery logistics, safety testing, and a final fill—and understanding the timeline helps you plan around it.

Here's what happens from the day you call us through your first full tank.

Permitting and Site Assessment

Once you contact our team, we schedule a site visit. Our technician walks your property to check setback distances from buildings, property lines, and other structures. New Mexico's terrain—rocky soil, elevation changes, seasonal weather—affects where we can safely place your tank and how we'll prepare the ground.

Depending on your municipality, we may need a permit before installation. In some areas around our service territory, a permit is required; in others, it's not. We handle this step for you and factor any permit timelines into your project schedule. Most permits in our region process within 1–2 weeks, but we'll give you a realistic estimate when we assess your site.

Aboveground vs. Underground: What Fits Your Property

Aboveground tanks are the most common choice for residential customers in our area. They're faster to install, easier to maintain, and don't require digging or frost-line considerations—important in New Mexico's variable winter conditions. Aboveground tanks sit on a concrete pad and are typically 120–500 gallons, depending on your heating and appliance needs.

Underground tanks are an option if you prefer them out of sight, but they require excavation, frost-line compliance, and more complex installation. Underground work takes longer, costs more, and depends on soil conditions. If you're in a rocky area (common in our region), digging can uncover obstacles that add time and expense. We'll discuss both options during your site visit and help you choose what makes sense for your property and budget.

The Installation Timeline

Once permitting is complete, we schedule delivery and installation. Here's what the day looks like:

Preparation (1–2 hours before arrival). Our crew arrives with the tank, concrete pad materials (if needed), and all fittings and piping. We mark utility lines, set up the pad, and position the tank according to code clearances—typically 10 feet from doors and windows, 5 feet from property lines, and clear of high-traffic areas.

Tank placement and piping (2–4 hours). We secure the tank, run copper or steel piping from the tank to your home or building, and install the regulator and safety shut-off valve. If you're connecting to a furnace, water heater, or appliances, our technician coordinates with your HVAC or appliance contractor if needed.

Pressure testing and leak detection (30–60 minutes). Before we fill the tank, we pressurize the system with nitrogen and use a soap solution to check every connection for leaks. This is non-negotiable—it's how we ensure your system is safe. If we find a leak, we fix it on the spot.

First fill (30 minutes). Once the system passes the leak test, our delivery truck fills your tank. You're now ready to use propane.

Total time on-site is usually 4–6 hours, depending on tank size, distance from the truck, and whether the ground requires extra prep work.

Clearance and Safety Requirements

New Mexico's weather—dry summers, occasional heavy snow, and dust storms—means your tank placement has to account for drainage and accessibility. We maintain clearances from buildings, vents, and electrical equipment per industry safety standards. Your tank also needs to be accessible for our delivery driver on fill days, so we avoid placing it in tight corners or behind landscaping.

If you have questions about where we're placing your tank or why, ask. We're happy to explain the reasoning—it's your property, and you should understand the setup.

What Affects Installation Cost

Several factors influence the total cost of your installation:

Tank size: Larger tanks cost more but reduce fill frequency.
Aboveground vs. underground: Underground installations require excavation and are more expensive.
Site prep: Rocky or uneven ground may require extra concrete work.
Distance from the truck: If your property is far from the road, setup takes longer.
Piping runs: Longer distances from tank to your home mean more materials and labor.
Permitting: If your area requires a permit, there may be a municipal fee.

We provide a written estimate before we start work, so you know the cost upfront. We don't surprise you with add-ons.

After Installation: Your Responsibilities

Once your tank is installed and filled, keep the area around it clear of snow, leaves, and debris. In winter, our drivers need safe access to fill your tank. If you notice any unusual smells (propane has an added odorant so you can detect leaks), frost buildup on the tank, or damage to piping, call us right away.

We recommend scheduling your first fill-up before the heating season begins. In our region, that's typically September or October. If you wait until November or December, you'll be competing with dozens of other customers, and we may have longer wait times.
