Purchased a Westinghouse Heat Pump in 12/07/2008, Split systems model: ft4bf-06k/ftd080300162 Air handlers model: b4vm-x36k-b/b4d080105591 Since installation, we experienced problems after problem with our heating system. At first, the heat pump was not heating (winter 2008/2009) or cooling (summer 2009) properly. At installation, the installer gave us a 1-year warranty on the labor. However, after the first year we experienced more and more problems with the heat pump system. Here is some of the work done to the unit only in 2010 alone: July 2010 unit not cooling (loosing Freon, technician refills heat pump unit with Freon); October 2010 unit not heating (loosing Freon, technician refills heat pump unit with Freon); December 2010 unit not heating (Freon leaking ' technician replaces air handler heating coil); January2011 rubber burning smell coming from air handler unit, unit stops operating (electrical panel melted needs replacement). Since all this work has been done my Electric bill has doubles in kW usage from prior year: February bill for period of 12/13/2010 to 01/17/2011 goes up from 3069 kW (2010) to 6011 kW (2011); March bill for period of 01/17/2011 to 02/15/2011 goes up from 2847 kW (2010) to 4816 kW (2011). Call PECO (local electric co.) out to check the meter, no problem found. Meter working fine! Called the servicing company out again to check the unit and find out why my electric billed double in usage. Today the installer came to the house again and found out another part damaged: The Regulator Freon needs to be replaced. What next? You decide if its worth it!
