Geothermal Paducah, KY
More and more residents in Paducah, Kentucky are choosing geothermal heating and cooling.
When the seasons change, outdoor temperatures fluctuate. Underground temperatures don’t experience as drastic of a change, due to the insulating properties of the earth. When you dig four to six feet below the ground, temperatures will remain relatively constant year round. A geothermal system, consists of an indoor handling unit and a buried system of pipes, called an earth loop and/or pump to reinjection well.
The pipes on the earth loop are usually made of polyethylene and buried horizontally or vertically, depending on the job site. When an aquifer is available, AAA HVAC engineers may prefer to design an “open loop” system in which a well is drilled into the underground water. Then water is pumped up, ran past a heat exchanger, and then the water returns to the same aquifer, through “reinjection.”
In the winter, fluid circulating through the system’s earth loop or well absorbs stored heat from the ground and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it through the building, as if it were an air conditioner working backwards. In summer, the geothermal HVAC system pulls heat from the building and carries it through the earth loop/pump reinjection well, where it deposits the heat into the cooler earth/aquifer.
Geothermal Tax Credits
In February 2018, the 30% geothermal federal tax credit was reinstated through 2019 and can be retroactively applied to installations “placed in service” on January 1, 2017 or later. Property is usually considered to be placed in service when installation is complete and equipment is ready for use. However, if the system is part of the construction or renovation of a house, it’s considered placed in service when the taxpayer takes residence in the house. To save the most on your installation, you’ll want to act quickly—this credit is set to decrease each year through 2021 with the amount dropping to 26% in 2020 and 22% in 2021.
• 30% of total system cost through 2019
• 26% of total system cost in 2020
• 22% of total system cost in 2021
• No limit to credit amount
• Can be used to offset AMT tax
• Can be used in more than one year
• Can be combined with solar and wind tax credits
• Can be combined with energy efficiency upgrade credits
What Else Makes Geothermal HVAC Different?
Ordinary HVAC systems burn fossil fuels to generate heating, geothermal systems do not, and instead they transfer heat to and from the earth. The only type of electric power is used to operate the systems fan.
Main Components of a Geothermal Cooling and Heating System
* The Heat Pump
* The Liquid Heat-Exchange Medium (Open or Closed Loop)
* The Air-Delivery System and/or Radiant heating
Geothermal Maintenance – Beyond Routine
Geothermal systems need little maintenance. When installed correctly, which is critical, the buried loop can last for generations. A geothermal system requires little maintenance because the system’s fan, pump and compressor is stored inside, protecting them for extreme weather. At AAA HVAC, we do suggest periodic checks, changing the filter, and coil cleaning.
