"MTP replaced my exterior sewer pipe after it was found to be in terrible condition. Mark did a great job getting it done. I didn't have the funds needed for this unexpected job and another person came over to work out a loan for me with GreenSky. I wound up on the wrong type of loan and didn't realize it until I got a letter saying my payments were about to change and interest charges would be incurred. I have called 4x and the person who I did the loan with hasn't called me back. He had the (genuinely lovely) person who handles the phone calls ring me back to say I to speak to the loan people, but the loan folks say it is an issue on the end of MTP. If he had simply called me back and even spoken to me after 3 weeks of calling, I wouldn't be writing this."

Open Loop Geothermal Heating, Cooling, Hot Water Systems use drilled GeoExchange supply and return ground water. energy wells. Closed Loop Geothermal systems use drilled Geoexchange energy wells with fluid filled U bend underground piping to transfer this free Solar Powered Geothermal Energy. Standing Column GeoExchange energy wells are a hybrid of open and closed loop using a single well in rock formations to transfer this free energy. So as the saying goes let's " Drill Baby, Drill " for the right reason.
