The original question was directed at a direct replacement for a Duo Therm 59136 with a heat pump . The reply seems to be another brand with a heat strip?? I need to purchase two 15000 btu replacements for our aging Duo therm 59136s with heat pumps and 15000 btu. Can you furnish these items? tks

@WilliamB We don't carry those units anymore because we found they don't reliable replace Dometic upper units and work well with the lower unit. Only solution we have would be an all new setup that includes the upper and lower. Is that something you'd be interested in?
