Overall, our experience with Dandelion was positive, and like any large, multi-phase project, there were some inconveniences that were resolved. Despite these issues, we would undertake the project again. We upgraded from an oil heating system (over 20 years old) to a geothermal system for heating and air conditioning. - Initial Consultation: In early November, Patrick interviewed us online to address our concerns. He analyzed the property using special software to determine if the project was feasible (considering dimensions and terrain) and provided us with an estimate for the entire project. - Feasibility Study: A few days later, a team of engineers visited the property to verify that the house met the requirements and proposed a system. We already had HVAC ducts in the house, although it was proposed to add more ducts to increase the volume of hot/cold air on the second floor. We felt that the team that came was very professional and used science to estimate the system. We had obtained quotes from other heating companies, but they did not seem as professional. - Drilling: Permits were submitted with the city around mid-November. By mid-December, the excavation was done. A team of two skilled workers carried out the vertical drilling to insert the pipes/loops that would later be connected to the house. One area for improvement throughout this process would be receiving notification a few weeks in advance that they were ready to come for the next phases. In general, we were notified only a couple of days in advance. It would be helpful to have a timeline diagram for the phases so that users know what to expect from subsequent steps. - Installation: At the end of March, we were informed that the loops would be connected to the basement of the house. Dandelion brought an excavator, and within a few hours, the loops were already installed in the basement. A week later, we were told that everything was ready to start the installation. Five vehicles arrived with various teams, and the system installation began. One team removed and disconnected the old equipment, another made duct connections for the new machine, another assembled the new equipment and installed the thermostat, and another filled the loops with the necessary fluid. By the end of the third day everything was installed. The week after installation, we had some issues, but as soon as we called to report them, we received a response and a technician was sent to resolve them. Almost a month after installation, the thermostat stopped working, but it was replaced, and it has been working well since. During the installation, we noticed a lack of communication between the teams (sales, design, engineering, installation, maintenance). It seems there is a need for a Project Manager to oversee all the aspects of the project, rather than the project being handed off between different teams. - Permit Closure: At the end of May, an electrical inspection took place that lasted no more than 10 minutes. Now, in early September, the final plumbing inspection was completed, and it was also very quick. It was originally planned for early July but was delayed due to availability issues with both us and the inspectors. Overall, all the employees from Dandelion who worked on the project were very friendly, with a good attitude and knowledge. It was evident that they were trying to do their job well. As mentioned at the beginning, despite communication issues, some changes, and problems that arose, we are satisfied.
