Heat Pumps "usually" last no more than 5 to 8 years.
Its the 5-8 years that call attention & disagreement.
If you had said 8-10 its more palatable and somewhat closer to fact.
Personally, I would have said 10-12.
Its a funny biz though... I've seen really old Carrier's that lasted 30 years and on the other hand, say in the early 80's when for a period, they used Bristol compressors and had a very high failure rate.
First heat pump in the house went 9 yrs and lost a compressor (warrenty). Second compressor is on it's 14th yr. Everything else is original unit yet except I oiled the outside fan motor once(knock on wood). Yeah, you would think it should last 30+ years as many refrigerators/freezers do, but i guess the complicated switching valves and stuff just gives up.
Keep up the good work Doug.
