Backwords a/c for heat.
I'd like to heat my shop a little in the winter. It doesn't get that cold here- but it can for a few days.
I have an older 2 ton cooling only system I pulled out and was thinking.
If I installed the air handler outside and the condenser inside- wouldn't that give me heat on 35* days and above?
I could increase the air handler blower speed if needed to help prevent icing when it gets colder and install a freezstat. ?
Crazy idea huh?
Fit a reversing valve and accumulator on it. And defrost board!
I'm thinking there won't be much load on your evaporator coil so the pressures would be off. It might work a little bit but it would be inefficient.

Wouldn't work. Coils not designed for the application.
You could try re-piping the outdoor unit so the compressor discharges into the suction line, remove the meterting device from the indoor coil and install it at the outdoor unit between the liquid line and outdoor coil, and pipe the outdoor coil to the compressor suction. Then come up with some creative way to defrost.
Or you could buy a heat pump.

You can get a dry 22 hp for pretty cheap.
You can get a small gas furnace cheaper
Just wait till you change out a heat pump.
It was just a challenging thought as to why it would or wouldn't work.
I guess piping it would be the better solution. Defrost would be a problem if it did ice up and a freezstat would probably just keep it off all the time below 32* anyway.
I can just run the elect heat (No natural gas pipe run to the shop- 90' away from the house.) I hate giving the elect co-op my money though.
I made a used motor oil drip heater out of a freon jug with a furnace draft blower that heats up real well, gets red hot and rumbles, but I don't like the idea of possible runaway burning oil.
i dnt think it would work but you should wait for a change out and do it anyway...sounds like a fun beer drinking project for the weekend
bring couple of the local college chick and a bed....lol.
