Q: Why are propane prices not the same for every customer?

A: Unlike oil, propane prices are based on the number of gallons you use per year. Because the uses of propane vary significantly the consumption can range from 25 to well over 1000 gallons per year. Those that use more propane pay less accordingly.

Q: What does propane smell like?

A: By nature, propane is clear and contains no scent at all. For safety purposes propane companies add a substance known as ethyl-mercaptan to the propane fuel. Ethyl-mercaptan has a strong rotten egg, or skunk-like scent, which allows the consumer to smell it in the case of a leak. If you smell something similar near your appliances and your tank it is possible that you are low in fuel. Ethyl-mercaptan is heavier than propane and sinks to the bottom of the tank so when the tank is low on fuel the ethyl-mercaptan smell will become more noticeable.

Q: How do you know when to deliver for customers on automatic delivery?

A: We deliver based on two factors: the current outside temperature and your usual usage. Our computer system calculates the amount of gallons each customer uses between deliveries and can therefore determine a general delivery schedule after 2 or 3 deliveries have been made. If there is going to be a drastic change in your usage such as: you are temporarily out of town (1month or more), more people have moved in to your residence, you are using more heat due to construction at the home, you add a new appliance or a new heating system, you should contact our company to let us know so we can ensure that you do not run out of fuel.

Q: What are the advantages to locking in the price of fuel for the winter?

A: The greatest advantage to pre-buying or locking in your fuel price for the heating season is that you are protected in the event of an increase in fuel prices. Typically oil and propane prices tend to rise when the demand is the highest, which in our case is in the winter months. For this purpose, pre-buying your fuel in the summer or fall for the winter months can save our customers hundreds of dollars. We offer a Guaranteed Price Protection Program which enables our customers to choose 1 of 3 money saving options.

Q: What are the different options you offer on your Guaranteed Price Protection Program and when is the best time to join the program?

A: Proulx offers Guaranteed Price Protection Plans that lock your fuel rate for all DIFFERENT kinds of terms and programs. These plans are available for Oil and Propane.
