Heat pump?

So, even though the heat pump is not producing near enough heat to heat the house on its own, the heat it does produce is still more efficient than the strips. Also, shutting off your compressor in cold weather usually means starting it again in cold weather, which, even with a crankcase heater, is hard on compressors. Below 20 degrees, my compressor never shuts off, by design. The strip heaters cycle and the compressor keeps chugging along. Most wear and tear on a motor occurs on start-up, and factor in off cycle liquid migration displacing crankcase oil, cold weather starts can shorten compressor life.



This is just ridiculous. Knowing the science is essential to installing and working on this equipment. Not a day goes by that I don't use physics and chemistry. The guys that never learned the science are the guys who call me for help. Knowing the science is also recommended for giving advise on the internet. Spelling "capillary tube" right also helps.



Sure we want to sell something, but good pros sell heating solutions, not just boxes like the manufacturers and distributors seem to want us to sell.



Those are the errors I find.

Dual fuel is nice, if more complicated. I am starting to fall out of love with complicated systems as I get older. More parts to break do break more, and customers don't understand how fancy is supposed to work. I have never had to run a no heat call on a wood stove, and I wish more people had them and knew how to use them when they need them.

Chef i have never held with that near 100% run time . Fellow i know called me from Mi one summer said his Ac was falling way behind .Well everyone knows in Mi they don't have real hot summers ,that year they did the only time his house was cool was of a night . You are correct in running long enough the remove the moisture . I got by 40 years with out an expert i think i can make it the rest of the way .

Post #4:
"On your unit - one other thing I would verify is that the outside coil is not freezing up and that the defrost cycle is working properly."

No one.
