New incentives coming to Virginia could make geothermal heating and cooling more accessible for residential builders, potentially changing how energy-efficient HVAC systems are incorporated into new housing developments.
Beginning in 2027, Virginia utilities are expected to purchase geothermal renewable energy credits tied to reductions in electricity demand from qualifying heating and cooling systems. The program adds another financial mechanism for builders and homeowners considering geothermal installations.
The policy shift follows similar incentive activity in neighboring Maryland and comes as builders face growing demand for energy-efficient residential systems without significantly increasing construction costs.
Virginia’s Geothermal Renewable Energy Credit program allows qualifying geothermal systems to generate tradable credits based on energy savings compared with conventional electric heating systems.
According to Dandelion Energy, the credits could reduce upfront installation costs by approximately $10,000 per home when monetized in advance. The company is also combining the state incentive with federal tax incentives and a lease-to-own financing structure developed with Upstream Lease.
Dandelion says the combined approach can support zero-down geothermal installations for qualifying projects. Under its leasing model, homeowners can lease systems for monthly payments while potentially reducing heating and cooling expenses.
The approach is particularly relevant to production builders, which typically need to balance construction costs with features that improve long-term operating performance and buyer appeal.
Geothermal systems use stable underground temperatures to provide heating and cooling, reducing reliance on conventional outdoor HVAC equipment.
For developers, the technology can provide another option for meeting energy-efficiency goals while offering homeowners potential reductions in heating and cooling consumption. Geothermal systems can also eliminate conventional outdoor condenser units, creating additional design flexibility for residential developments.
Dandelion reports that its systems can provide estimated heating and cooling savings of 30% to 40% compared with air-source heat pumps, although actual savings depend on the property, system design and operating conditions. The company has installed more than 4,000 heat pumps and drilled more than 1 million feet across the Mid-Atlantic region.
The company has also worked with residential builders including Lennar, Dream Finders and Ward on geothermal communities in the region.
Virginia’s geothermal incentive structure gives residential builders another pathway to incorporate high-efficiency HVAC technology into new homes. The program could also help shift geothermal from a niche feature associated with custom housing toward a more scalable option for production-built communities.
With the first geothermal renewable energy credit solicitations expected in late 2026 and the broader program taking effect in 2027, builders and developers operating in Virginia will have a new incentive mechanism to consider when evaluating HVAC systems, construction costs and long-term energy performance.
