Glassman Corporation is a leader in high performance geothermal heating and cooling systems. Geothermal systems offer the energy-conscious owner low operating costs and environmentally responsible operation. An additional benefit is improved comfort.

A geothermal system taps into the Earth to capture free, renewable energy. The Earth absorbs about 47% of the sun’s energy that reaches it, storing that energy in the ground. A geothermal system extracts that free energy for heating during the winter. In summer, the system removes heat from the home and dumps it into the cooler Earth. This transfer of heat energy is done through a series of pipes buried in the ground, sunk in a pond, or through well water. Because it moves heat instead of burning fossil fuel to generate it, a geothermal system is more energy efficient.

Geothermal heat pumps also provide warmer indoor air temperatures than conventional air source heat pumps. Because they are sized to run significantly more than a standard furnace, they don’t ‘blast’ hot air followed by an extended time when air is not being circulated. A geothermal heat pump provides steady, warm air — making it the most comfortable heating system available.

For cooling, the geothermal heat pump dehumidifies better than conventional air conditioning systems. Lower humidity equals greater comfort.
The U.S. Environmental Protection Agency calls geothermal systems “the most energy efficient, environmentally clean, and cost-effective space conditioning systems available today.”

→ Why choose geothermal?

Geothermal is an excellent option because it is:

  • Economical. Savings up to 60% on operating costs compared to ordinary systems.
  • Tax Credits. The Bipartisan Budget Act of 2018 reinstated the geothermal heat pump tax credit. Taxpayers can claim a 30% credit on all systems in place by December 31, 2019. Learn more here.
  • Comfort. Geothermal heat pumps provide warmer indoor air temperatures than conventional air source heat pumps. Because they are sized to run significantly more than a standard furnace, they don’t ‘blast’ hot air followed by an extended time when air is not being circulated. A geothermal heat pump provides steady and warm air, making it the most comfortable heating system available.
  • Low Humidity. For cooling, the geothermal heat pump dehumidifies better than conventional air conditioning systems. Lower humidity equals greater comfort.
  • Environmentally Friendly. Geothermal is a clean, green, and renewable technology.
  • Reliable. Geothermal units have a longer life expectancy than ordinary air conditioners & heat pumps, and operate for years with little maintenance because of fewer moving parts.
  • Quiet. Since no outdoor unit is required, geothermal units are housed in fully insulated cabinets for quiet operation.
  • Safe, Clean. No flame, no flue, no odors.

    "Glassman Corporation was involved in a significant building upgrade to Ashland Jr-Sr High School, beginning in March and concluding in September (2018)...Many items were discussed, such as interrupting class schedules, time on the site, addressing safety and security concerns, and interaction with students and staff...They took the time to show their pride in their work, but more importantly, they took the time to treat us like family."
