Underground oil storage tanks often remain unnoticed for years, even decades, especially if they have been abandoned in place. We’re often posed questions from our customers about underground oil tank removal and replacement. We’d like to provide some answers for you that will hopefully prove helpful in your research.

How Do I Know If There’s An Underground Oil Tank On My Property?

If you’re unsure if there is an underground oil tank on your property (or where it is located), don’t worry. It can be easily found using a metal detector, ground penetrating radar, or a magnetometer sweep. These methods will determine the location of the tank, and let a certified professional evaluate the scope of work that needs to be done for the removal/abandonment and replacement.

When Should You Remove An Underground Oil Tank ?

While there is no law in place requiring the removal of an underground heating oil tank prior to sale, many home owner’s insurance companies will not insure a home with an underground oil tank, and some banks may even require underground oil tank removal before they will finance the home.

If the tank is older, removal of the tank sooner rather than later is always advisable. A leaking underground storage tank can be costly if soil remediation is required, not to mention damaging to the ground water and environment.


What’s Involved With An Underground Oil Tank Removal?

If you’re unsure if there is an abandoned underground oil tank on your property, the first step is ascertaining if there is one and where it is located. This is easily accomplished using a metal detector, ground penetrating radar, or a magnetometer sweep. These methods will determine the location of the tank, and let a certified professional evaluate the scope of work that needs to be done for the removal.

Once the location is determined, a certified professional like the ones on the 7 Oil Company Tank Division team can evaluate the extent of work that will need to be done. This can vary from home to home, and is determined by factors like the location and size of the tank, the amount of excavation to be done, and any structures, trees, fences or other impediments to the excavation. If liquid remains in the tank, it must be evacuated and disposed of at a permitted recycling or disposal facility.

When the underground oil tank is uncovered, a hole is cut in the tank so a technician can enter and thoroughly clean the tank in place. The tank is then removed and inspected for obvious signs of ruptures or leaks, as is the soil around the excavation site. Your local municipality will inspect both the excavation and the tank itself. Once this municipal inspection is complete, the excavation is backfilled and the job is done. We highly recommend one extra step to our customers: obtaining at least one soil sample to be tested for Extractable Petroleum Hydrocarbon (EPH) levels.

If The Levels Are Too High?

If the levels of petroleum hydrocarbons are found to be too high, then certain further steps must be taken to adhere to New Jersey Department of Environmental Protection regulations and obtain a “No Further Action” letter. This letter is essentially a ‘clean bill of health’ for the property. Contaminated soil must be excavated and transported to a fully permitted recycling facility, and replaced with certified clean fill.

While excavating contaminated soil, the soil is continuously monitored and screened for the presence of petroleum hydrocarbons while it is loaded directly onto transport vehicle to be taken to the recycling facility. Once this screening process indicates acceptable levels according to DEP guidelines, final confirmatory soil samples are taken and analyzed, and a report is given to the DEP so that the No Further Action letter can be obtained.

The excavation is filled with certified clean fill dirt, and generally compacted and raked to existing grade. You as the homeowner can then sit back and enjoy your new yard, knowing that duly licensed and certified professionals have taken care of everything for you.

We hope this has taken some of the mystery out of underground oil tank removal for you. If you have questions that weren’t covered in this article, or would like further information, please give us a call at 856-786-0707 or email us!

Central AC Recharge, Repair or Replacement?

When it comes to central air conditioning, there are lot of letters and numbers floating around. R22…R410a…what does it all mean to you as a homeowner? When it comes time for an AC recharge, do you go ahead and do it, or is it time to consider replacing your system? Pondering this question can be downright…chilling. We’d like to answer some of the more common questions about the refrigerant mystery.

What Is An AC Recharge?

Central air conditioning works by running a refrigerant through copper tubing between an evaporator coil, condenser, and compressor. As the refrigerant moves through the evaporator coil, it absorbs heat from the warm air moving across the coil. The refrigerant then moves to the outside condenser and compressor, where the heat is dissipated. An AC recharge is needed when the level of refrigerant becomes too low for the system to work properly. Needing an AC recharge is an indicator of potential problems, as air conditioners are sealed systems and low refrigerant levels hints at a leak somewhere in that system.

R22 versus R410a: Recharge or Replace?

R22, more commonly known as Freon, has for years been the refrigerant used in most air conditioners. Since 1992, the government has been shifting away from its use. R410a, commonly known as Puron, is the replacement. All newly manufactured air conditioners are made to use R410a. In fact, R22 will no longer be commercially available by 2020. The limited production has made R22 hard to come by, and more expensive than R410a. R22 is also less efficient, and more harmful to the environment than R410a. If your air conditioning system uses R22 and is in need of a recharge, it may be time to consider a new system. At the time of writing, R22 can cost anywhere between $100 and $200 per pound. With the average air conditioner using 5 to 11 pounds of Freon, this can lead to a costly AC recharge. A good rule of thumb is to multiply the cost of a recharge or repair by the age of the unit. If the result is more than 5000, that’s a good indicator that it’s time for a new air conditioner. For example, if the AC recharge uses 5 pounds of R22 at $125 per pound, the cost of the refrigerant alone would be $625. If your performing this service on a 12 year old air conditioner, multiply $625 x 12, and you get a figure of 7,500. Time to think about a new AC installation.

Fix It Or Replace It?

What type of repair is needed? A new evaporator coil? A new condenser? The higher the cost of the repair, the more you should consider a new air conditioner installation. Couple this with a unit that uses R22, and the answer becomes apparent.

Another thing to consider is the efficiency of your existing unit. The Air Conditioning, Heating and Refrigeration Institute uses a rating known as SEER, or Seasonal Energy Efficiency Ratio to measure the cooling efficiency of air conditioners. The SEER rating indicates the ratio of cooling in BTU’s to the energy consumed in watt-hours. The higher the rating, the more efficient your air conditioner is. An air conditioner with a higher SEER rating could save you a lot of money on your electric bill. The example below shows how upgrading from an existing unit with a SEER of 10 to a high efficiency unit with a SEER of 14.5 can save you up to $1300 per year. Broken down over 12 months you could save $108 a month. With financing as low as $59 a month, a new air conditioner could be a sound investment!

Prepare Your Air Conditioner For Spring

Spring is here! It’s time to start thinking about spring cleaning, warm weather, and preparations for summer. A complete air conditioner tune-up is a great way to get ready for the warm summer months that are approaching. We’ve come up with a few things that you can do to help maintain your air conditioner.

Tune Up Your Central Air Conditioner


air conditioner filters

The easiest thing and most important thing for any homeowner to do to maintain their air conditioner is change the filters regularly. Clogged and dirty filters can drastically reduce air flow, and thereby reduce the efficiency of your unit. Central air conditioner units usually have the filter located somewhere along the return ductwork, in the air conditioning unit itself, or in the furnace. A window mounted air conditioner will have the filter located right in the front of the unit facing into the room. Air conditioner filters should be changed every few months, or even more frequently if there are dusty conditions present, pets, or if smoking is allowed in the home.


Air Conditioner Condenser Maintenance

The evaporator and condenser coil can collect dirt and debris over time. This dirt can restrict air flow and insulate the coils, causing them to lose efficiency and hampering their ability to absorb heat. Regular cleaning of these coils prevents these conditions, and extend the life of your central air conditioner. Bent coil fins can also restrict air flow. Most home improvement stores carry “fin combs”, which can be used to gently straighten the coil fins back to their original positions.


air conditioner condensate line

Occasional clearing of the drain lines improves the A/C unit’s ability to remove humidity from the air inside the home. This both improves the A/C unit’s efficiency, and helps prevent the discoloration that can occur in carpet and furniture from excess moisture within the building.


sealed window air conditioner

If you’re using window air conditioners, make sure that any gaps between the air conditioner and the window frame are sealed, so that as little air as possible escapes. The sealing material should be in contact with the metal structure of the air conditioner. A moisture resistant material is best.


air conditioner air flow

Making sure that air flows freely around your central air conditioner can go a long way towards making it run efficiently and keeping it running for the long haul. Make sure that you keep any vegetation that is near the condenser well pruned and away from the A/C unit. At the beginning of spring, open up the grate at the top of the condenser and remove any debris that may have fallen in during the course of the winter.
