How it works
The ground under your yard stays around 55°F all year. A geothermal heat pump moves that steady heat into your home in winter and out of it in summer. Most projects run about two weeks door to door.
Typical timeline: 2 weeks
We walk your property, review your utility bills, and confirm your yard can host the loop field. You get a straight answer on day one, including whether geothermal is wrong for your site.
Our LoopLink certified designers size the ground loop and equipment to your home's actual heat load, not a rule of thumb. The design is engineered for the geology under your lot.
Our own drilling crews bore the wells and set the U-loop pipe, typically in one to two days. We have installed over a million miles of loop pipe across Virginia and Maryland.
WaterFurnace factory trained installers set the heat pump, connect the loop, and commission the system. We register your warranty and file your incentive paperwork before we leave.
Services
Design, drilling, installation, and every service call after. Nothing is handed to a subcontractor.
Complete WaterFurnace systems: loop field, heat pump, ductwork tie-in, and hot water assist. One contract, one crew, engineered start to finish.

02We repair and maintain all geothermal brands, not just the ones we sell, plus conventional furnaces, air conditioners, and heat pumps. If your current company gave up on your system, call us.
03Aging geothermal unit or a fossil furnace on its last winter? We swap it for a current WaterFurnace system, reuse your existing loop when it tests healthy, and cut your bills again.
Equipment
EER measures cooling efficiency, COP heating. A standard air conditioner is around 13 EER. These start at 22.
The flagship
The most efficient geothermal heat pump on the market, full stop. Variable speed everything: compressor, blower, and loop pump ramp to exactly the output your home needs, so it sips power and holds temperature dead steady. If you want the lowest possible bills, this is the unit.

Most HVAC companies sell geothermal as a sideline and rent a drilling rig when they land a job. We are the opposite: a geothermal specialist with our own designers, drillers, and installers, fluent in the geology from the Blue Ridge to the Chesapeake. That is why other contractors call us when their projects get complicated.

I've kept meticulous records and the average monthly utility bill has been $175 for a 5,000 sq ft home. That includes heating, AC, hot water, lights and appliances. Big fan of WaterFurnace and of this crew.

Crew drilled two wells, trenched, and left the yard so clean you can't tell where they worked. First winter without a propane delivery in 22 years.

Three companies told us our old geo unit couldn't be fixed. These guys repaired it in one visit and replaced it two years later when it was actually time. Zero pressure either way.

The REC checks are real. First quarterly payment arrived four months after startup, on top of a house that finally holds 71 degrees everywhere.

From site survey to startup in 12 days. The design lead walked us through the loop math like we were colleagues, not marks. Proposal price was the final price.

Swapped a 30 year old oil furnace for a 5 Series. House is quieter, no more fuel truck, and February's bill was a third of last year's. Should have done it a decade ago.

Most single-family installs in our area land between $25,000 and $45,000 before incentives. In Maryland, the 30% federal credit, the $3,000 state grant, and REC payments routinely cover more than half of that. Your proposal shows the exact math for your address before you commit to anything.
Yes. Six feet down, the ground holds about 55°F even in January. The system pulls heat from that steady reserve, so output does not drop off the way an air-source heat pump's does on the coldest nights. No backup fuel needed for a properly sized system.
A vertical loop needs a work area of roughly a parking space per borehole for a day or two. We trench the connections, backfill, and reseed. By the next season you will not find the wells without our map.
The indoor unit is rated for 25 years or more, roughly double a conventional furnace or AC. The ground loop itself carries a 50 year warranty and typically outlives the house's second roof.
Yes. We repair and maintain every geothermal brand, and a large share of our service work is fixing systems that other companies installed or gave up on.
Yes. We offer financing options that let the monthly payment sit at or below what you save on utilities, so most owners are cash-flow positive from the first month. Details come with your proposal.

The honest range is $25,000 to $45,000 before incentives, and the federal credit takes 30% off the top. Here is where the money goes: the loop, the unit, the ductwork, and the two line items people forget to compare.
