Waterfurnace

I am extremely disappointed in Waterfurnace! I have had this unit for 4 years and have had nothing but problems. Approximately, 6 months after the unit was installed repair service was required. On average, the unit is repaired twice a year. Despite my calls to Waterfurnace, who claim to have a great customer service department, I am left with an inadequate product. As I read in a previous review, I too, am given the option of replacing the compressor at a cost of 800.00 or replacing the unit for 3400.00 I find this unacceptable! What-ever happened to standing by your products? I will not buy another Waterfurnance product again.
