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". Upgrade to geothermal, and never buy heating oil or natural gas again. 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.”
"He has done a good job."

"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us.

"A Raving Review for Green Mechanical LLC! If you’re looking for the absolute best HVAC service around, look no further than Green Mechanical LLC! This company is truly a gem, and I couldn’t be more thrilled with the incredible service they provided. My heater had been misdiagnosed by another company, leaving my family and me in the cold—literally! Thankfully, I called Green Mechanical LLC, and they completely turned things around. From the moment I called, I knew I was in good hands. Devin Green, the owner himself, came to my house to personally assess the issue. This level of dedication and care is something you just don’t see every day! Devin’s professionalism, deep expertise, and genuine commitment to solving the problem made all the difference. He didn’t just slap on a temporary fix or rush through the job—he made sure to thoroughly diagnose the issue and explain every step of the process to me. A huge shoutout to Jacob and G, who also worked on my system. They were punctual, knowledgeable, and incredibly respectful of my home. Their teamwork and attention to detail were top-notch, and it was clear they take immense pride in their work. Thanks to Devin, Jacob, and G, my heater is now working perfectly, and my family can finally enjoy a warm, comfortable home again! I also want to emphasize how important it is to support small businesses like Green Mechanical LLC. These are the companies that truly care about their customers and their communities. Devin and his team are local experts who go above and beyond to deliver top-notch service, and they deserve every bit of your trust and business. If you need HVAC services—whether it’s a repair, installation, or just regular maintenance—do yourself a favor and call Green Mechanical LLC. Their commitment to excellence, fair pricing, and outstanding customer service make them a company you’ll want to recommend to everyone you know. Thank you, Devin, Jacob, and G, for your amazing work and dedication. You’ve earned a lifelong customer! 🌟"

Horizon Services is the region’s largest and most well respected plumbing, heating and air conditioning company, with nearly 600 employees serving tens of thousands of homeowners throughout Delaware, Southeastern Pennsylvania, Southern New Jersey, and Northeastern Maryland. After a quarter of a century in business, Horizon Services remains fully committed to setting the industry standard for customer service, installation, and focusing on things that are important to busy homeowners: respect for their time, their home and their property; up-front pricing, and an unconditional 100% money back guarantee.
"Stellar service from a company with a well-earned reputation for solid workmanship. These guys are the real deal. Ramon was exceptionally knowledgeable and spent a great deal of time explaining what needed to be done. Once I signed the contract, everything happened at lightening speed. The servicemen showed up on time, were careful to not damage the doors, walls, or hardwood floors when they hauled in the new gas boiler and water heater, and left the basement in spotless condition. After I sold the oil stored in my old oil tank, Horizon was out the very next day to cut up the tank, clean the inside of it, and haul it onto the driveway for inspection. Not a single drop of oil was spilled. They are that meticulous about their work. A shout out not only to the remarkably zenlike Ramon, but also to Robert, who patiently and respectfully dealt with an unnecessarily finicky inspector."

Geothermal heating or cooling system installations FAQs
Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.
The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.
Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
