Thread: Heat pump question

I saw a system that was reported to be a heat pump, but I did not see a reversing valve at the compressor. The compressor did operate as a heat pump. Is the reversing valve inside of the compressor?

The only heat pumps I see without a reversing valve are heat only units, such as pool heaters or similar (heat only) units.

The reversing valve on a Trane heat pump is behind a cover panel to the left of the service panel cover. You cannot see it looking down through the outdoor fan motor like you do on most heat pumps.

This one was an American Standard
Is that the same

I found a picture of a reversing valve on a Trane heat pump at this web site: HEAT PUMP TRANE TROUBLESHOOTING - HEAT PUMP

Trane was acquired by American Standard in the 80’s.

Thanks Jeff

I run across a few homes where they list the unit as a heat-pump but are actually an electric forced air furnace, and an A/C unit that uses the same air handler. Most of these are older units, pre 1985. Heat pumps are very popular here, but sometimes what the listing shows is not what is actually found. Yes I have had to explain what a heat-pump is to many agents, buyers and sellers.

Also when I test the heating side of heat-pumps, I try to run it both as a heat-pump and also kick on the Aux or Emergency heat, and note the Temp. rise for each.
