We are super impressed with Greenwood Heating, As you wish Electric and Earth Heat and would recommend them without hesitation.
Description of Work: Looking to replace an aging inefficient gas furnace with a more eco friendly option, we contacted Greenwood heating about installing a Geothermal Heat Pump. The salesman, Kevin, was prompt, nice and very knowledgeable. He was able to explain the ins and outs of the system, how it functioned, how it is maintained the promises and the realities. After working with Kevin through several on-site discussions, we opted for a gas-hybrid geothermal system. We also had Greenwood install a Heat Recovery ventilation system, high efficiency whole house filter, installing a new return, replace our soft ducts and joist ducts with hard ducts, for a total of $47,000. From the initial install through completion took 8 weeks - with 3 different phases. Phase 1 included installing the gas furnace which we would use during power outages (using a generator, it would not drive the geothermal unit). This phase included installing the heat exchanger, filter, and HRV. They also did the majority of the duct work. I was amazed at greenwood’s creative solutions to some of the challenges they faced in our house, from routing around poorly placed joists, routing through ceiling, and connecting through the floor - a floor which spanned an addition. Phase 2 included installing the ground loop. Earth heat is a commercial company which specializes in the ground loop installation. 2 trenches are dug 6 feet deep, and two sets of coils of plastic pipe laid in those trenches, hooked up to a manifold which ultimately is hooked into a flow center inside the house. It was then filled with an anti-freeze solution. Phase 3 included the geothermal unit hookup to the flow center and the heat exchanger using a refrigerant line. A system this complicated should not be expected to run flawlessly initially, and mine was no different. How a company handles problems with the system is where companies really shine. Our system had the following problems, and solutions: The geothermal compressor had a strange sound, which was causing light dropouts and eventually faulted the system. It turns out that there was an interesting interaction between the transformers in the hybrid. Greenwood was able to work with the electrical contractor - As you wish electric to solve the problem. The geothermal unit was not shipped with a refrigerant charge, which caused some construction debris to enter the system. Greenwood was able to isolate the problem and implemented a solution quickly. The compressor was causing severe electrical dropouts, which resulted in dimmed lights. Greenwood and As you wish diagnosed the whole house current and tracked it down to a power company issue. We contacted the power company, who instrumented our house and the transformer for the community. Turns out that the transformer is undersized, but within specs so they said ‘deal’. Greenwood was able to find a solution using a soft start transformer which eliminated motor power spikes and improved the runtime electrical requirements, correcting the dimmed lights and improving our electrical efficiency.
