Energy – Propane

Our approach to propane solutions is about providing you with as many options as possible. We develop a custom plan that fits your needs and budget to service home heat customers, commercial operations, and agricultural businesses.

Residential Propane

Our residential propane solutions offer the most diverse and customer-friendly contracting in south central Wisconsin and northern Illinois. With multiple contract options, we customize a program to fit your needs by offering Even Pay, Prepay, Booking, and Budget contracts.

You can also take advantage of low market pricing and the opportunity to lock-in propane pricing with multi-year contracts. And our contracts never have any hidden or rental fees.

Landmark offers the ultimate propane reliability with our propane tank monitoring system, which is free for the first year of service. This 24/7 access to tank levels and usage history gives you peace of mind knowing you’ll never run out of propane, even during the cold winter months.

Propane Autogas

The popularity of propane autogas vehicles is increasing throughout the country. Fleets including buses, law enforcement, and delivery vehicles are discovering that propane autogas offers reduced emissions, year-round reliability, and the lowest total cost-of-ownership available. We help fleets take advantage of this clean-burning fuel’s economic and environmental benefits.

With propane autogas, you’ll reduce your impact on the environment, but also see the benefits in your bottom line. Autogas vehicles need fewer oil and filter changes, require less maintenance, aren’t affected by cold weather like a diesel vehicle, and don’t require compliance additives.

Our knowledge and skill in this area, along with the strong relationships we’ve established to set up new and updated refueling stations across Wisconsin, have made us the area’s leader in propane autogas.

As a thank you for your propane business, Landmark would like to reward you. For referring friends, family or neighbors to Landmark propane, you will receive $50 for EVERY referral.
