Services
Commercial mechanical, start to finish. New construction and replacement.
Geothermal HVAC
Federal credit up to 50%
Ground-source heating and cooling for schools, churches, nonprofits and businesses. We drill and pipe the well field, set the heat pumps and connect them to the building, whether it’s new construction or a replacement for aging rooftop units and boilers.
- Vertical well fields under parking lots, fields and lawns
- Hybrid systems that pair a smaller well field with a boiler or cooler
- Heat pumps that work with existing ductwork where it’s sound
- Union labor that meets federal prevailing wage and apprenticeship rules
Schools, churches and other nonprofits receive the federal credit as a cash payment. Businesses take it against their federal taxes.

Geothermal HVAC
Geothermal costs more to install. Then the federal government pays 40% of it.
The well field is the expensive part. The federal credit closes the gap, and the system costs less to run for decades after.
Who gets what
The credit is 30% of the geothermal system, plus 10% for U.S.-made materials and another 10% near a retired coal mine or plant, or on a brownfield. It applies to the geothermal equipment (the ground loop, heat pumps and related parts), not every line of a project, so the final credit depends on how the bid breaks out.
- SchoolsSchools, churches, nonprofits and local governments get a check. They can’t use a tax credit, so the IRS pays them the amount in cash.
- BusinessesTake it off your federal taxes, or sell the credit to another company for cash.
- LifespanThe well field lasts about 50 years. Indoor heat pumps last 20 to 25. Rooftop units last about 15.
