Northland Geothermal LLC was established by Tod Cosgriff to help create awareness of the geothermal process and to provide a local company that specializes in the installation of Geothermal systems. Cosgriff has been in the heating business for over 20 years with his company, Cosgriff Sheetmetal, and has been installing goethermal units since 2003.

In his experience, the economic advantages of using geothermal to heat and cool a home are unsurpassed. While the cost of fuel oil or gas jumps around dramatically, the relative cost of using electricity does not change. The study of geothermal energy has been around since the early 1980's and it is continually redefined and has evolved into the process it is today.
