Selecting a contractor is the single most important decision a consumer will make when deciding to install a geothermal heat pump system. The design, sizing, and installation of the geothermal system is the most critical part of the process. Strandlund Refrigeration, Heating & Cooling has been in business since 1962 and started doing Geothermal heat pump service and installations in 1985. The Strandlund's own 4 geothermal systems themselves. We have over 300 geothermal installations and service many of our competitors flawed systems. We maintain 4-5 refrigeration trained technicians in our service fleet.
Most heat pump manufacturers make good products. The difference between success and failure solely falls upon the contractors experience, training, and knowledge of how to design and install the ground source heat pump and it's loop field system.
Consumers would be wise to make decisions based on the contractors information - such as references, testimonials, experience, expertise in the geothermal field and service - versus buying because of the brand name of a heat pump. All geothermal heat pumps that are designed for closed loop applications will work in Minnesota and Wisconsin's climates. It comes down to the sizing, design, and installation of that geothermal heat pump and loop field that determines whether or not the consumer will save energy, save money, reduce emissions, and reap all the great benefits of geothermal technology.
