Building lifelong relationships with clients by exceeding expectations as an expert in HVAC, Electrical & Plumbing.

Geothermal Services

JK Mechanical taps into the free energy source buried in your backyard. We take advantage of stable temperatures underground, in a pond, or well, to keep you comfortable while minimizing monthly costs. Geothermal heating and cooling operates on electricity but relies on the earth’s thermal energy to maintain perfect year round temperature in the average-sized home for a dollar a day.
