I've had a great experience with Spring Home. They have replaced my broken furnace and aging AC and were very professional, provided great customer service and were reasonably priced.
Before settling on the equipment, their technician Jack stopped by a couple of times to give us different options and explain the differences between the types of available equipment and brands (brand differences, single stage vs two stage furnace, case coil etc). He was incredibly helpful, patient and worked with us to get the best combination for our house in terms of performance and available rebates. (in our case OPA and Lennox).
The installers did an excellent job, worked fast and clean and did a really nice job of running the piping and condensate pump hoses. Jack came back after the job to make sure that we were happy and everything was done properly.
Really good company, I would highly recommend it.
