“We are pleased to give our highest recommendation for Synergy Heating & Cooling and for the work and service of Derrick Ellefson. Synergy installed a new heating/cooling system for us in 2012: prior to that Derrick did other service work for us. He is exceptionally knowledgeable, careful and competent in his work and very fair in his pricing. He does the work in a timely manner and is thorough in his clean up and follow up. We are impressed by his experience and by his awareness of the latest technology in his field. It has always been a good experience to have him in our home.”
