Bassett has performed twice annual service and cleaning on our geothermal unit for the past several years. Their technicians are very knowledgeable on the operation and maintenance of our system and keep it in excellent condition. Kaleb, the tech who performed the service this fall, is a very competent professional. In addition to getting our unit ready for winter he provided a number of tips and insights to help me get the most efficient operation and life out of it. Thanks Very Much!!
