We love our Water Furnace, which was installed by Allgeier in 2006. Prior to that we had had nothing but problems with a Carrier Geothermal unit installed by another local company. Rick worked with us to use most of our current plumbing and we couldn't be happier! We are part of the Silver Service Plan and Matt is the most wonderful technician in the world: honest, professional and knowledgeable. No one does it better!
