What do I do if the Oil Burner fails to operate?

Check the following:

1) Be sure that the oil burner switch is ON.
2) The thermostat should be set above room temperature.
3) Make sure there is oil in the tank.
4) If the burner does not run at all, check for a blown or loose fuse.

If the burner still fails to operate, call us for service.

How energy efficient is it to heat my home with oil?

Very Efficient! The average oil heat system consumes less fuel than gas, and oil burners produce the most efficient flame when compared to gas systems. According to the U.S. Department of Energy, oil heat systems are 16% more efficient than gas heat systems and 30% more efficient than electric heating systems.

Will oil heat keep my home warm enough?

Absolutely! The oil heat flame quickly burns at 2,200 degrees Fahrenheit. This is the reason oil consumers are much more comfortable in their homes versus those who complain that their electric heat pump does not provide the comfortable warmth of oil during those cold days of winter.

Can I get my heat to come on faster if I turn the thermostat up higher?

No. It takes time for your heat to come on. Once the thermostat has switched on, it doesn’t matter if you put it up one degree or all the way. Set it to the desired temperature and wait a few minutes.

Can I tap on my oil tank to see if it is full?

No. Your oil tank will sound hollow even if it is full. If you think your gauge is not working or you do not have a gauge, you can use an oil tank measuring stick to measure the level of oil in your tank.

How often should I have my ducts cleaned?

Approximately every 2 years. If you have recently completed a renovation, have incurred major water damage or have mold issues you may want to consider having your ducts cleaned sooner than the 2 year window. Also people with asthma, allergies, pets or who have smokers in their homes should consider having their ducts cleaned more frequently.

How much water does a small leak waste?

Even a drip from a faucet or toilet could waste over 1,000 gallons per year. A stream as small as 1/16 of an inch can waste up to 74,000 gallons in 3 months!

I don’t know how old my water heater is, when should I replace it?

If you need to ask, it is time! As a general rule, use twice the manufacturer’s warranty as a guide. So, a 6 year tank warranty heater should be good for 12 years. Many factors affect this estimate so have your water heater inspected yearly. Plan to replace the sacrificial anode in your water heater to get the longest life possible from your equipment – every 5 years is the approximate useful life of the anode. When it is completely eroded away (used up), the risk of leaking increases as time goes by.
