Heat Pump problems

Heat Pumps "usually" last no more than 5 to 8 years. Same for residential Heat Pump units. I state this for people that are using their unit MORE than 8 months a year. Since Heat Pumps cool and heat, they are run twice as much so they will wear out twice as fast. Now, if you full time and stay in a warm climate, your Heat Pump will still be used as much as a standard AC unit. Since Rv's are usually recreational and NOT full time homes, the AC or HP may last 10 years or more, it all depends on how many days a year the HP is used. Doug

Doug, you maybe correct about RV heat pump units lasting 5-8 years, but your giving miss information about residental heat pump units lasting only 5-8 years. There are thousands of residential units that are 25 plus years old and running just fine. I am a HVAC contractor in California, I recently changed out a heat pump system that was 35 years old, so please don't compare a residential heat pump system with a RV heat pump system when it come to longevity.

I do enjoy reading your anwsers to many of the RV related problem and have learned from those answers, keep up the good work.

I base MY comments on residential on my OWN experience with Heat Pump in my old house. And Friends also. I had to replace the complete system after 8 years and when I had 4 different HVAC contractors come out to give estimates, and I asked WHY I had to replace so soon, they ALL stated that due to double duty (Heat and COLD) they wear out twice as fast. Sorry, but it makes sense to me. Yes, some may last longer, but It all depends on how well the maintenance was and how often it was run. Doug
