Schwantes responded to our service call promptly... and Mike did a great job diagnosing the problem. We just need to wait for a new part to be shipped in to complete the repair. Our system is still under warranty so no complaints on cost.Update: Mike finished the repair and the system is now up and running as expected. Great service!Update: Our system had been running great all winter until an "Alert" popped up on our thermostat regarding our heat pump. Schwantes responded promptly to our service call. Mike did a great job diagnosing the problem and found a leak in the A-Coil. Steve and Truman arrived the next morning and installed a new replacement A-Coil, recharged the system and checked out the entire system before declaring the system was good. They were both very efficient, knowledgeable, and a pleasure to work with! Once again, our system is still under warranty, so no complaints on cost. The service has been great! They demonstrated that they stand behind their products and their workmanship.read more
