Geothermal Heating

We are the #1 Geothermal Heating and Cooling Experts in South Jersey, Central Jersey, and Southeastern Pennsylvania.

The U.S. EPA calls geothermal "the most energy efficient, environmentally clean and cost-effective space conditioning system available". And D&L Custom Services is a leading geothermal installation and maintenance company serving New Jersey and Southeastern Pennsylvania.

Upgrade to geothermal, and never buy heating oil or natural gas again. Plus, D&L's geothermal system replaces both your home's existing air conditioning and heating equipment with a powerful heat pump and safe, underground pipes that move heat between the earth and your home. In the winter, the ground loops move heat stored in the ground into your home. In the summer, the ground loops return heat from your home to the ground.

Don't just take our word for it when it comes to D&L's geothermal expertise. Here's what one of our recent customers had to say:

“D&L has been an absolute life saver. We had the hardest time finding a tech who knew anything about geothermal systems, until we called D&L... A real standup, old school, quality service company. D&L got a new long-term customer in me, and I strongly recommend them.”

How Geothermal Heating and Cooling Works

  1. Water or a refrigerant moves through a loop of pipes.
  2. When the weather is cold, the water or refrigerant heats up as it travels through the part of the loop that's buried underground.
  3. Once it gets back above ground, the warmed water or refrigerant transfers heat into the building.
  4. The water or refrigerant cools down after its heat is transferred. It is pumped back underground where it heats up once more, starting the process again.
  5. On a hot day, the system can run in reverse. The water or refrigerant cools the building and then is pumped underground where extra heat is transferred to the ground around the pipes.

Geothermal Frequently Asked Questions

What are the components of a geothermal heating and cooling system?

There are two main parts of a geothermal system – a heat pump inside your home that typically takes the place of your old furnace, and a buried "ground loop" of pipes outside your home that circulate fluid which transfers heat between your home and the earth.

What are the advantages of geothermal systems?

Geothermal combines heating and cooling into a single highly-efficient system with low operating costs that don't fluctuate with changes in gas or oil prices. There are no gas fumes, furnaces or potential carbon monoxide leaks. Geothermal is the cleanest heating and cooling technology available, and has the lowest ongoing cost of operation.

How long do geothermal systems last?

Install a geothermal system today, and prepare to enjoy reliable heating and cooling for decades. Geothermal heat pumps typically last 20 to 25 years, and the ground loops outside your home can last for more than 50 years.

Are there tax incentives available?

Yes! In fact, the Inflation Reduction Act of 2022 extends existing geothermal tax credits, and makes geothermal one of the most incentivized clean energy solutions on the market. A 30% federal tax credit with no upper limit covers most equipment and labor costs for residential geothermal projects. Eligible structures must be used as a residence by the taxpayer, although primary residency isn't required. In fact, if geothermal is installed in more than one home, there's no limitation on the number of times the credit can be claimed. As with any federal tax program, there are some nuances and specific equipment requirements. But D&L can help you maximize any credits you're eligible for. All in all, geothermal heating and cooling systems are now more economical than ever.
