Welcome to our information center! We’ve grouped the most frequently asked questions we get from our customers and divided them into categories. If you don’t see a question/answer addressed here, please contact us and we’ll be glad to help.
A: Our headquarters are in Danbury, but we service homes in Fairfield, Litchfield, and New Haven counties. See our service area page for specific towns and zip codes.
A: We guarantee all our work, we obtain all necessary permits before beginning any work, and our workers are fully insured for both worker’s compensation and general liability.
A: Usually it’s only a matter of one day, excluding weekends. We can come out to your home at your convenience to determine and recommend the right size system for you and then give you an estimate.
A: Although every job is different and some take longer than others, it usually takes one day.
A: Yes. Whenever possible, we will recommend a system that will not only give you maximum comfort and equipment performance but save you money on its purchase through rebates or other incentives.
A: You are not alone. Many of our customers are having problems making ends meet. We recommend that you take a look at (1) our EZ Pay Price Protection Plans, which can cut your winter fuel bills by 50%, and (2) our home energy saving tips, which suggest many other ways to cut the costs of heating your home.
A: Yes, we offer financing through several financial institutions. To learn more, contact us today.
A: Yes. One of the things that allows us to be competitive is our storage capacity. We buy in larger quantities than some fuel dealers, which means a lower cost for us and a lower price for you. It’s also important to remember that we offer you advantages that fuel discounters don’t—like a dedicated team of highly-trained technicians, some of whom are always on call for you, 24 hours a day, 7 days a week.
A: We take the number of gallons you used last year, multiply by projected prices for the coming season, apply any credit balance on your account and divide the total by 10 months.
A: Before you contact us, we can give you some tips to make sure a service call is really needed. This could save you the cost and inconvenience of an unnecessary service visit. Plus, it will ensure our technicians are working where they are most needed.
If at this point you still don’t get heat, call us immediately.
When a service technician arrives, let him know everything you did to the system before he begins working on it.
You should also let him know if anything out of the ordinary happened, like an unusual noise, a strange smell or smoke.
In many cases, this will help the technician find the problem—and get your heat back on again—faster.
A: Heat is generated by burning oil, natural gas or propane inside the furnace. This happens in the combustion chamber, which gets very hot. Air absorbs this heat in the furnace’s heat exchanger. Next, the blower sends the heated air through a system of ducts, and warm air circulates through the home.
A: The heat exchanger is the main component of your furnace. If the heat exchanger has a crack or a rust hole, combustion fumes (including carbon monoxide) can contaminate the air in your home. This is a potentially deadly situation and should be addressed IMMEDIATELY. A cracked heat exchanger usually requires replacing the entire furnace. If you suspect that you might have a cracked heat exchanger, or a carbon monoxide problem caused by your furnace, turn the system off immediately. Then call Jennings Oil right away for service.
A: Installing a new furnace with two levels of heat and a variable speed motor is a good solution. These “smart” motors automatically adjust the volume and speed of air based on your home’s temperature requirements.
A: One indicator is Annual Fuel Utilization Efficiency (AFUE). All heating equipment manufactured after 1980 is required to have a label indicating its AFUE. The AFUE ratio is a measurement of a heating system’s seasonal efficiency, taking into account how well the system performs over an entire season of starts and stops. Modern heating systems can range in efficiency from 81% to 95%. If your system’s AFUE is lower than this range, we recommend that you contact us to talk about your replacement options.
A: Different people feel comfortable at different temperatures. Pay less attention to the number on the thermostat display (or the position of the temperature indicator on a nondigital display) and more to how comfortable the room feels to you. When you feel comfortable, check the setting. That’s the right temperature for you.
A: Absolutely! Programmable thermostats are especially useful for people who are away from home at regular intervals. They allow for customized comfort settings around the clock, and they can cut heating and cooling costs by as much as 10%!
A: In an indirect-fired water heating system, the domestic water is heated by hot water from the boiler. A typical design is a water tank with coiled pipes inside. These coiled pipes connect to your boiler. Hot water from the boiler passes through the coil, which heats up the domestic water surrounding it.
A: Heating oil produces the hottest flame of any home heating fuel. This means that an oil-fired water heater heats water fast. How fast? On average, oil-fired units heat water three times faster than gas heaters and five times faster than electric units.
A: In order to maintain your water heater, you can take the following steps:
A: No. At this time there are no federal laws governing active, underground, home heating oil tanks.
A: Yes. We offer price protection contracts year-round. You may stay at market price for now, and ask us to send you a price protection contract in the future.
A: No. There is no fee for the fixed price. There is only a fee for downside protection (capped price).
A: We recommend contracting for 85% of your expected annual usage. If you are currently a customer of ours, we supply you with information on your annual usage over the past several years.
A: We want all of our customers to use all of their contracted gallons before the expiration date. When you get your last delivery that includes contracted gallons, any additional gallons will be priced at our daily market price. We will then mail you a new price protection contract.
A: State law requires that we purchase the oil to match what our customers contract for. If you still have gallons left, we must sell that oil at our market price. You agree to pay us for the difference between the contracted price and the market price for the gallons that are remaining. We will then mail you a new price protection contract.
