Frequently Asked Questions


What Is Propane?

Propane is a naturally occurring product simply composed of hydrogen and carbon molecules (known as hydrocarbons). Other members of the hydrocarbon family are methane (natural gas) and pentane (gasoline).

Propane naturally occurs as a gas at atmospheric pressure but can be liquefied if subjected to moderate pressure. It is stored and transported in its compressed liquid form, but by opening a valve to release propane from a pressurized storage container, it is vaporized into a gas for use. Simply stated, propane is always a liquid until it is used. Although propane is non-toxic and odorless, an identifying odor is added so the gas can be readily detected.

2.      Naturally found as gas


3.      Liquefies at moderate pressure for transportation and storage


4.      Non-toxic, colorless odorless, tasteless - artificial odor is added


Where Does Propane Come From?

First of all, approximately 90% of propane is domestically produced!  Propane is not produced for its own sake, but is a by-product of two other processes, natural gas processing and petroleum refining.  US production of natural gas and petroleum normally provides enough propane as a byproduct to meet all consumer demand.

Natural gas plant production of propane primarily involves extracting materials such as propane and butane from natural gas. Similarly, when oil refineries make major products such as motor gasoline and heating oil, some propane is produced as a by-product of   those processes. It is important to understand that the by-product nature of propane production means that the volume made available from natural gas processing and oil refining cannot be adjusted when prices and/or demand for propane fluctuate.

In addition to these two processes, excess demand is met by imports of propane and by using stored inventories.   Although imports provide the smallest (about 10 percent) component of U.S. propane supply, they are vital when consumption exceeds available domestic supplies of propane. Propane is imported by land (via pipeline and rail car from Canada) and by sea (in tankers from such countries as Algeria, Saudi Arabia, Venezuela, Norway, and the United Kingdom).

·         Production is not demand driven.


·         High demand is met by imports & is time sensitive.



What Influences Propane Prices?

Crude Oil and Natural Gas Prices

Propane is a by-product of both natural gas and petroleum and its price is based on the going rate for both.

Supply/Demand Balance

Colder-than-normal weather can put extra pressure on propane prices during the high demand winter season because there are no readily available sources of increased supply except for imports. And imports may take several weeks to arrive, during which time larger-than-normal withdrawals from inventories may occur, sending prices upward. Cold weather early in the heating season can cause higher prices sooner rather than later, since early inventory withdrawals affect supply availability for the rest of the winter.

Proximity of Supply

There are three supply points in the propane distribution chain:

The consumer tank - A larger consumer tank will allow the consumer to last through supply shortages.

The supplier storage - A larger supplier storage will allow for more deliveries to the consumers before resupply is required.

Wholesaler storage - Suppliers who receive resupply from hundreds of miles away are subject to transportation and logistical restrictions & problems.

Markets Served

Propane demand comes from several different markets that exhibit distinct patterns in response to the seasons and other influences.

Residential demand, for instance, depends on the weather, so prices tend to rise in the winter.

The petrochemical sector is more flexible in its need for propane and tends to buy it during the spring and summer, when prices decline. If producers of petrochemicals should have to depart from this pattern for some reason, the coinciding demand could raise prices. And when prices rise unexpectedly, as they do sometimes   in   the winter, petrochemical producers pull back, helping to ease prices.

Prices could also be driven up if agricultural sector demand for propane to dry crops remains high late into the fall, when residential demand begins to rise.

How does “Pre-buy” work?


Since prices spike almost every winter for the residential propane market, we offer a pre-buy program each summer that permits you to lock in low summer-time propane pricing then use it through the following winter.  Payments for this service may be either lump sum or level/budget billing. 



How does “Level or budget billing” work?


For our level billing customers, we evenly distribute the year’s propane costs over the year to lessen the burden on a monthly basis.  Give us a call or come in and we can get you set up!



How do I read the gauge on my propane tank?


Not all tanks have gauges. If your tank does have a gauge, it is located on the top of the tank, usually under a liftable hood. (Note: Please be careful when you lift the hood–insects sometimes nest there.)



Why isn’t my tank filed to 100 percent capacity?


Your propane is delivered and stored in liquid form. Propane liquid, for example, will expand (become a gas) nearly 17 times as much as water over the same temperature increase. As a result, tanks and cylinders are never completely filled with propane liquid. Tanks are filled to about 80 to 85 percent of their capacity. This leaves a space above the liquid, which allows the propane liquid to expand freely due to changes in temperature.

There are several important characteristics that you need to understand about propane stored in containers. First, heat is added to propane in a tank or cylinder by transfer directly from the air surrounding the container. Hot days, cool nights, rain and snow are a few of the many factors that affect the temperature of the liquid. Because of these temperature changes, you may see fluctuations in your container gauge.



How do you know when to fill my tank?


Automatic Fill Service: We utilize software that forecasts your home’s average fuel consumption depending on the weather patterns and what equipment you have that burns propane.  We’ll use this information to automatically schedule you for a delivery when your tank is forecast to be 20%.  Please give us a call if you add or remove any equipment such as a stove, water heater, pool heater, etc. so we can keep our system accurate and your prices low!


Will Call Service: You need to periodically check your tank and call us when it reaches 30% in order for us to fit you into our delivery schedule so it may be filled when approximately 20%.



Why does Propane smell so bad?


Propane in its natural state is both colorless and odorless.  For these reasons and because propane is flammable, a chemical malodorant with a distinctive smell is added to provide a method of detection in the event of a leak.  Ethyl mercaptan is normally used for this purpose since it is chemically stable when mixed with propane and has many of propane’s physical characteristics.  One can be reasonably assured if ethyl mercaptan’s distinctive odor is detected propane vapors may also be present.  Some people say the smell is like rotten eggs.  Ask for a copy of our propane safety plan brochure that includes “scratch and Sniff” sample to identify the smell.



What if I plan to do any excavating or remodeling around my home?


Please visit or dial 8-1-1 first. 811 must be called 48 hours in advance to mark any utility lines, BUT, they do NOT mark propane gas lines, private electricity, water sewer, or phone lines. Contact our office to have your gas line marked. Not only is it dangerous to dig around underground utility and gas lines but fines and repair costs may be imposed if damage is done.
