Is my oil tank safe?

As we all know, Maine weather takes its toll, causing ground shifts, frost heaves, rust, and general wear, all of which can affect a heating oil supply tank and its piping. Weather, corrosion, and poor maintenance can lead to spills, smells, leaks, well water contamination, and lower property values. It’s time to see if your tank and piping are in shape.

We’ve prepared the following checklist of items that you can easily observe about your oil tank. But remember, look – don’t touch. Even if you can see rust or an oily patch of wetness on the tank’s surface, do not touch your tank. It’s best to contact Crooked River Heating and A/C, LLC, and let a professional take care of it.

  1. Are the tank legs unstable or on an uneven foundation?
  2. Do you see rust, weeps, wet spots, or excessive dents on the tank’s surface?
  3. Are there any drips or signs of leakage around the oil filter or valves?
  4. Do the oil lines run either under concrete or above ground without being encased in a protective tubing?
  5. Are there any threats of snow or ice falling on the oil tank or the filter? The two main causes of spills come from copper lines leaking under a concrete floor slab and from falling snow and ice damaging fuel filters and outside lines.
  6. Are there any signs of the tank’s vent being clogged or blocked by ice or snow? (Screened vents are available to prevent insect nest problems.)
  7. Is the overfill whistle obstructed, or silent when the tank is being filled? (It should whistle.)
  8. Are there any signs of spills around the fill pipe?
  9. Is the tank’s gauge cracked, stuck, or frozen? Do you see oil or staining around it?
  10. Is your tank more than 25 years old?
  11. Is your outside tank a dark color? (It should be painted a light color to minimize corrosive condensation inside the tank.)

If any of your answers to this checklist are YES, please contact us for a more detailed inspection and corrective measures.

Is it time to replace my furnace or boiler?

If your furnace or boiler is more than 15 years old, you should seriously consider replacing it. New technology is always pushing the limits of efficiency. Odds are, you’ll save money on your heating costs right away.  But REMEMBER…..Crooked River Heating & A/C, LLC will NOT try to sell you a new unit if it is NOT needed!

Obviously, if repair costs are mounting, it’s time to replace your unit.

Too much noise could indicate a serious problem. A repair could remedy it, but consider the age of the unit. It easily could be wiser and more cost effective to replace it.

A yellow flame instead of a blue flame is bad. An improperly burning furnace can be a serous health hazard and may be  producing too much carbon monoxide.

Uneven heating throughout your home or business is a sign of problems. Depending on the age of unit, it may be better to replace it.

What does an emergency switch look like?


What does a reset button look like?
How often should I have my furnace/boiler cleaned?
Once a year (oil, propane or natural gas)
I have no heat. What can I check for?
  • Is the Emergency Switch turned on?
  • Do you have fuel (oil or propane)?
  • Is there anything blocking the venting system?
  • Is there a circuit/fuse that is blown?
  • If it is a Miller furnace, is the door shut tight on the furnace?
    DO NOT push the reset button, more than once; pushed more than once can cause bigger problems.
