Geothermal.contractors

Silvernail Plumbing, Heating & Cooling has operated in Oklahoma City since 1921, making it one of the oldest active mechanical contractors in the state. Now in its fifth generation of family ownership, the company designs and installs ground source heat pump systems tailored to individual properties, assessing soil conditions, lot size, and load requirements before specifying a loop configuration. Vertical drilling is available for smaller or constrained lots, while horizontal ground loops are offered for properties with open acreage. Services extend to geothermal maintenance, ground loop pressure and antifreeze checks, and hybrid systems pairing a geothermal heat pump with a gas backup unit. Smart thermostat integration and zoning are included in installation scoping. The firm holds HVAC and plumbing contractor licenses in Oklahoma and serves residential and commercial customers across the Oklahoma City metro, including Edmond, Nichols Hills, Deer Creek, and surrounding communities.
