Professional Geothermal HVAC Repair, Installation, & Maintenance in Richmond, VA
Geothermal is the most common name given to heat pumps that use water or underground energy transfer rather than air transfer. Water and underground sources of energy remain more constant under extreme temperatures. With more constant temperatures available for energy exchange, geothermal heat pumps do not typically require electric heat for backup, and thus yield much higher efficiencies with lower energy use.
Geothermal HVAC Systems Are Environmentally Friendly
By tapping into renewable energy, geothermal heat pumps eliminate the combustion process and the associated threat to both your family and the environment. There’s no fire hazard, no fumes, carbon monoxide, carbon dioxide, or other greenhouse gas emissions. Considered the most environmentally responsible form of heating/cooling by the Environmental Protection Agency, geothermal HVAC takes advantage of the free energy source found in your own backyard and typically pays for itself in under five years.
How Do Geothermal Heat Pumps Work?
Geothermal heat pump systems operate using similar principles to air-to-air heat pumps but use water or the heat of the earth to transfer heat.
A fan passes ambient air over an evaporator causing the refridgerant to boil and form a vapor.
A compressor increases the pressure and temperature of the vapor.
The warm vapor passes through a heat exchanger to produce heat.
The vapor passes through an expansion valve and cools before repeating the process.
